Refrigerator Will not dispense water after replacing filter.

I had the same "hammering" problem. For me, replacing the new filter with the old still produced the same results. It turned out that the water pressure was too high for the filter. I have a spigot attached to my water supply. I replaced the o-rings, turned off the water source and while the water dispenser was running, I slowly turned it up until the "hammering" started. Then I backed off on the spigot a bit until the 'hammering" stopped. No more issues.

Hi, Wanted to share my solution that worked. Best of all, it just costs as much as a water hose washer !

I had the same exact issue after I replaced the water filter. Returned the original GE one, and got another GE one thinking it was a defect in the filter. That did not work. Then also tried a generic filter from home depot. Even that did not work. So it was clear it was not the issue with water filter.

I agree that the issue is with the filter head assembly. You can either replace the filter head or do a cheap fix by using a water hose washer. I got this idea after watching this YouTube video

https://www.youtube.com/watch?v=cjShdHoi...

Though he mentions to use a metal washer, a simple garden hose washer will work as good. Check it out. The video provides more information and shows about the part in the filter head that needs some extra push. A washer in the filter can do the trick.

I am very glad this worked and also to know the root cause of this problem. This appears to be a common problem and one definitely don't have to replace the filter head each time.

I am surprised by some of the answers that are posted.

Here is the problem and how to AVOID it.

The filter head assembly has a nipple sticking out in the spot that water will come into the filter. This nipple will be pushed out by the water pressure behind it to stop the water coming out when there is no filter mounted.

When you mount the filter it will push that nipple in slightly and allow the water to flow through your filter, in this process you can damage that nipple and it will not be pushed in, so water will not flow(or flow is reduced) unless you change the filter head assembly.

Solution: before changing the filter shot off the water AND eliminate the water pressure by turning on a cold water faucet.

This way your filter will not damage the nipple in the filter head assembly.

I finally fixed this problem permanently in my GE Profile side-by-side thanks to the helpful hints of others on this site. The solution is that you need to replace the entire filter head assembly. It consists of the filter head (i.e. the structure the filter attaches to) and water lines that connect to the main supply to the fridge. It's an easy and inexpensive fix. Good luck.

IMPORTANT AND TRY THIS! Make sure the filter is turned a FULL quarter turn. Sometimes it takes more force than you realize. It needs to be a tight seal to really work well.

For me, the solution to the hammering was to unscrew the filter and screw it back in again, TIGHTER. I don't think it was lined up properly before as I didn't have it tightened all the way. It could be some filters are slightly misaligned. My theory anyways and tightening it with my mechanic gloves worked.

The resolution for my Jenn-air: there is a black gasket that formed an outer seal. It must not have been seated properly after removing the old filter. I pulled it off and reinstalled it. Then installed the new filter with no hammer and strong flow.

I had the same issue and tried all of the above. I resolved it by reducing the water pressure to the fridge. My water hookup has a spigot handle like a garden spigot. With someone dispensing water (or trying to) I very slowly decreased the pressure by closing the valve until it stopped "hammering" and began to dispense water. I over-shot a few times adn had to keep adjusting until I found the most pressure without the ill side effects.

My husband figured it out. We had the same problem of just a trickle of water after replacing the cartridge. The answer is that you fill the new cartridge with water. IT TAKES AT LEAST 20 MINUTES TO FILL. You will notice little air bubbles at the fill hole . Add a little more water. Keep doing it till they have almost stopped. Then insert the cartridge as directed.

I just went through this hair pulling problem. I changed my filter and little to no water pressure. No its not air in the lines ,No its not freezing lines,No its not low water pressure in my house. If you put your old filter back in and it still has no pressure ,its no the filter "makes sense". I shut of my water line to my fridge and removed my filter. I looked inside and saw 2 small little tits that have an "X" marked shape, The centre one was filly out but the outside one was partially out. I you depress both of them they bounce back cause of spring pressure, The correct term "Check valves" possible one way . Any ways what i did was push the one that you think is not fully extended in and out maybe 20- 25 times with a long screw driver or a coat hanger. If you have a long pair of needle nose pliers handy grab the "X" valve and push in and out while turning side to side at the same time"keep in mind this is a plastic valve and could be damaged very easily" Hope this helps. Install your filter and turn water supply back on , this should do the trick.

I've read a lot of solutions to this problem. Here is the foolproof solution. Put the water filter bypass cap that came with the fridge back in (or buy a new one on Amazon). The water will now flow freely, but won't be filtered. Pull the fridge away from the wall and install an in -line water filter. Not as convenient as having the filter in the fridge, but there are a lot of different brands available and some of them last for years. Good luck!

Oh my gosh I am so glad I came to this page. We had to change our filter 2/3 days ago bought Samsung at lowes installed following all directions still no water. Took filter back to lowes for exchange thinking it was faulty put in new filter still no water!! For days we talked to SAMSUNG CS had email from Samsung CS still

no water. OK today I went searching found this page thank you all so much. We put filter in bucket of water to let fill up til no bubbles, while my husband inserted filter,removed filter and repeated I held down the water dispenser closed door and we had water.

unplug fridge for 30 seconds

Once fully installed turn filter back a little may be 1/2inch and try it. That is what worked for me after uninstalling it and re stalling it about 12 times.

This video helped me solve my problem. Water comes out great after buying 2 different filters. It just needed a washer. Watch the video.

For GE water filter MFINT. Same problem. Examined old and new filter saw that the ARROW that tells you where to insert the filter caused the filter to actually be installed incorrectly so it could not open the water line ,therefore getting the hammering noise.

Installed it with the arrow facing the back of the fridge and voila, it works perfectly!

Manufacturing defect??? The fact that the old filter worked every time I put it back in made me believe the filter was the problem, not the fridge!

Go with the washer (or at least try it first!). It’s simple and cheap.

As pointed out in the video link above, the filter assembly has a tiny "wedge" that must be fully pressed in for the filter system to work. It seems that new filters, even official brand ones, do not fully press this "wedge".

We bought garden hose washers at home improvement store. Make sure the inner cut-out is wide enough to go around the nozzle in the filter assembly.

One final comment: We bought rubber garden hose washers because it seemed like rubber was "better" than metal. However, after a week of the filter working, the noise and lack of water pressure returned. Upon removing the filter, it was clear that the little "wedge" had actually made an indent into the rubber washer. So I think a metal washer (possibly combined with a rubber washer) may be the real way to go. So a thin metal + rubber washer would probably be the best or just a single reasonable width metal washer or a hard plastic washer.

Check out the “slight” indent in the first rubber washer. It was much more pronounced right after removing it from the filter assembly (picture taken about 4 days after we switched it). We fixed the filter again by using another of the 10 rubber filters we bought but I’m willing to be in another week or so, we’ll have to either swap that one out with another “new” rubber one (or rotate or flip the one currently in the filter assembly). Hence, my suggestion to use a metal or “very hard” rubber one.

Thanks to @shrinivas for the easy and cheap fix!

I'm having the same issue. I've tried the remedies listed above. I think something has changed in the manufacture of the filters in recent years such that the filter is actually putting up too much resistance to water flow. When I try to fill the filter from the sink, It's tough to get water in or out. It just pools in at the top. The only solution may be to simply re-install the bypass plug and find another answer for the filtered water my family enjoys.

I had the same problem with a Samsung and the technical support dept said I must have used a cheap Wal-Mart replacement filter but they were wrong it was a Samsung.

After a year of not being able to filter my water I realized that I had removed a restriction on the supply side which would have increased my flow/pressure.

So I turned down the valve behind the refrigerator reducing pressure during a lower flow rate and it has been working ever since.

I have the same issue, no water flow. The Sears repairman came this morning and said the door with the

Water dispenser will have to be replaced. The refrigerator is under a service contract so I'm ok with it but it still doesn't make sense to me because all he did was check the filter and check the water flow. He checked the connection on the bottom of the door and decided I needed a new door because the problem is inside the the door. Your thoughts?

For those worried about water pressure to an ice maker/water dispenser in the door, in my Kenmore Model 106.55112 Side by Side Refrigerator Manual it says; "With the water filter removed, dispense 1 cup of water. If 1 cup of water is dispensed in 8 seconds or less, the water pressure to the refrigerator meets the minimum requirement." Not as accurate as professional methods but would give you a clue.

I had the same problem. I found that if I turned the filter in and out under pressure will holding the water flow open, eventually it started to work and is working perfectly now.... It's worth a shot.

I had this issue and I fixed it by filling the filter with water then connecting it. It's the air in the lines that causes the hammering noise. I think it would eventually purge the air if you cycle the dispenser for 5 sec then wait 5 sec, repeating the cycle as necessary. But the fill method seems to speed things up.

I re-read the filter cartridge and the last step is to bleed the system. Hold the dispenser line for four minutes. Ten minutes later we had working water.

I had the same issue after replacing the (GE) water filter--I had no water and no ice. I actually called a repairman, and he removed the filter and just reinserted it properly. The refrigerator is particular about alignment. There was no need to replace the filter system in the refrigerator.

I had a water hammering noise in my GE Adora side by side refrigerator when I tried to dispense water. Do not waste your time or money on repairs. I tried everything from thawing the lines to replacing the water coupler. It's as simple as making sure the water filter is installed correctly. You might have to loosen it a little by twisting a tiny bit to the left or take it off and install it again until the water starts dispensing without the hammering noise. Good luck.

Just had and solved this problem. At least for us..Remove the filter and shake it a few times. The water is trying to find its way through and resettling the contents changes the density. The hammering goes away..

after repair of water line and sears water filter that is full water will not dispense even after following sears instruction video

cannot purge system even after doing all told by sears vidio with door water

In my case, with a Samsung refrigerator (French door), this was a defrost issue. Water would flow fine with no filter, but with several brand new filters , it would not flow (or would flow briefly then stop). I have the rf263. Unfortunately , I've had nothing but problems with it. I put it in "fd" mode for 30 minutes,which melted the ice build up, and then the filter worked after that. Also the defrost helped clear my drain , since I had to install a modified piece which allows the defroster to actually melt ice in the drain. I know that the drain was clogged, because I had water in the crisper tray during the defrost. Why I would have to use manual defrost mode is beyond me. Samsung just makes all around garbage refrigerators. I know the original post was for ge, but a search for this problem for Samsung led me here.

Hi.

I had exactly the same issue.

After reading the comments here and looking at the write up in the package, I figured it was probably the water pressure going.

1. I located the water valve controlling the water going to the fridge.

2. I increased the water flow to maximum.

3. I told my son to try to get water from the fridge while I was decreasing the water flow.

4. Then at one point he said the water is now flowing.

What a relief!!!!!!!!

I had the same problem. When I remove the filter, it would dispense water. Based on the comments and solutions suggested here, I thought the filter was defective so tried it out with four new filters - all same results. So realized it can't be the filter.

So when the filter is removed, there is a part that looks like a plastic tray (it seems like its there to collect water when adding/removing filter). I tried adjusting that. I was able to push it in and out..so I pushed it in and then replaced the filter..and somehow it started dispensing water.

I am not sure if that fixed the problem or something else, for now I am afraid to take the filter out to prove the theory..but will try that when I have to replace the filter again.

For now I am good.

take off the plastic guard in front of filter. put old filter back on and watch how far it goes to turn water back on (take back off). then with new filter put it in! i bought my filter from walmart and it didn't go on as easy. but with a firm grip keep spinning and you will hear the water back on. your welcome!

The hammering is caused by a damaged cartridge filter. Specifically, the plastic weld holding the inner section of the filter to the outer section breaks free when the filter is installed over the refrigerator's water outlet nipple. I believe the root cause of the problem is a combination of poor filter design (the weak weld geometry) and the slight swelling of the nipple's O-rings that occurs over a period of time as the rubber slowly absorbs a small amount of water. The swollen O-rings cause a high force to be exerted on the filter's weld joint during installation. Through a Venturi action across the broken weld, air gets sucked into the upstream side of the filter element. This element does not easily pass air, thus the reduced flow due to a vapor-lock condition. The hammering occurs as a result of the dynamics of water flow, Venturi action and pressure on the loose inner piece. Eventually enough air gets sucked in to completely cover the inlet surface of the element and prevent any water form passing through.

The fix is twofold: replace the filter, and replace the refrigerator's outlet water nipple. I would apply a thin film of FDA-rated silicone grease to the O-rings of the nipple. This will ease filter insertion and retard swelling of the O-ring from the water.

I had no water pressure after changing filter..saw a fix on this site. I used a washer..then it worked..wish I had tried this earlier..now have an extra filter..but will just save it for next time:)

Install the filter like the box says, then find a cup or container heavy enough to engage the dispenser and leave the cup there for about 5 minutes, or you could just push it in with your hand for 5 minutes if you have nothing else to do. Lol. No frozen lines or broken fridge, the water has to fill the filter and push the air out of the line. You're welcome

Replaced the filter in my KitchenAid fridge with a new one - specifically, "EveryDrop by Whirlpool Refrigerator Water Filter 4 (Pack of 2)" from Amazon. It worked for a day or two, and then the water stopped flowing, accompanied by a very loud, annoying, disturbing jackhammer sound. In addition, upon removing the filter, the refrigerator's filter head (i.e. the "nipple") would leak water non-stop until either a filter or bypass plug were inserted, creating a big mess.

I called a repairman. He inserted a bypass plug, and the water ran fine. Because the bypass cap was long ago lost or thrown away by someone, I could not test this myself. He concluded that both of the filters I bought were defective, charged me $120, and went on his way. This smelled bad, but I had no information with which to counter the decision.

At the suggestion of someone here, I put the filter in a bucket and filled it entirely with water, forcing out all the air within. The effect has been threefold: first, the jackhammer noise can now only be heard for a couple seconds, then it goes away; second, the water now runs, albeit very slowly; third, when removing the filter, the filter head no longer leaks water. I'm very grateful for the latter, because now troubleshooting is less messy.

So, I've decided to live with the crappy water pressure and brief jackhammer sound. Between the overpriced OEM filters, the "repair" job, and a replacement bypass plug, I am about $220 in the hole. I'll wait until the filters give out before trying to contend with this problem again.

This issue is all over the Web, and I do think the most common cause is a bad product. Simply replacing the filter shouldn't break anything, but it does. I don't have a technical explanation for the issue, but it could not have been a coincidental, simultaneous failure of the refrigerator, or my home's water system. It must be a problem with come kind of interaction between the fridge and the filter.

I was having a similar episode with my samsung fridge filter. I realized after looking inside the slot where you insert the cartridge that the wide thread ears on filter and insert were sideways. I was trying to push it in with the handle in my hand straight up and down instead of sideways. After re-inserting the cartridge in sideways in my hand with the thread ears sideways i imediatley heard the water start filling the cartride and thats when i finished pushing in and turning clockwise untill locked in. Filter then dispensed perfactly. Boom done.

Put the old filter back in and all worked well. Repeated the process five times. Results consistent each time".

So what worked for me was to untwist filter slightly once fully seated then re tighten and repeat to process a few times until you feel a slight increase in tension. I'm assuming the rubber gaskets are making a better seal.

I had the same problem, no water flow after replacing the filter. Tracked my problem down. The supply line I used has an "anti flood valve" built into it. The little bit of water hammer after the filter change caused it to active. The solution- unhook the water supply at the shut off valve (which resets the valve) then reconnect it. Problem solved. I now have water!

I suspect most new refrigerators have some form of similar protection. Hope this helps those that have this problem in the future!

I put a sauce pan of FAUCET RUN hot water inside the fridge directly under the filter / water inlet tubes and bam. Problem solved. 2 October 2017.

I just spent 2 hours on this problem and finally found a fix.. The real solution is to replace the water filter mount because more than likely, the water inlet nipple is broken. It was mentioned in another solution so, I decided to check it out with a mirror and found out that it was crooked. I took the part out, after checking everything else, and saw that it has little wings that were supposed to keep it straight, allowing for it to be pushed to let the water flow into the filter. If it's not fixed, after the pressure builds, it slides off to the slide and closes again. So, the proper fix is to replace the mount... but I snipped off a tip of a plastic fork and used it to keep the nipple straight; re-mounted the mount; attached all the water lines I had disconnected; hooked up the new filter (GE MWF); and turned on the water... it worked!!

So, the short of it... turn off the water to the fridge. Unplug the fridge. Disconnect both water lines that go to the filter and the back, top cover where they go in from the back. Now you can take out the mount and replace it... or flip it over and find a way to fix the nipple... your choice...

Had the same issue and couldn’t get it to work. Old filter would work fine new one would hammer and restrict water flow. Last restort I compared to new & old filter side by side and noticed that the small tab below the dispensing nozzles on the new filter was a bit longer. Nipped a bit off the end of the tab to make it shorter and it worked ! Basically the tab on the new filter was preventing the filter from completely installing fully! Hope this helps !!

Hello. I spent a few hours on this "jackhammer" issue as well. I have a KitchenAid KFCS22EVMS model. In summary I used the "washer" solution approach. Simply, I used a standard rubber washer and put it in from the two "tits". I submersed the filter in a pitcher of water and waited a few minutes for the bubbles to stop. When I installed the new filter (as per instruction), I heard a release of air. I tried the water and no more jackhammer sound and the water flows nicely. What a relief!

It is so simple. if you have replaced the filter with the right filter, then just unplugged tehr refrig and plug it back. That way it reset the filter to flow the water!!!!!

I too am having the same problem! However, when I put the old filter back in, water does not now, run through it either !

Hi! I just replaced my water filter today on my side by side GE refrigerator. Same thing!!! Loud hammering sound and NO WATER! I finally decided to remove the housing cover for the water filter. I was determined I would fix this daggone thing. Anyhow, I found the culprit!!!! I pushed up above where the water filter goes and noticed a PIECE OF STYROFOAM!!! I wondered why I was able to get water with the original filter but not with the replaced GE water filter. I suppose they put that styrofoam there when the refrigerator was delivered. Anyhow, I removed that piece of styrofoam, and put the NEW water filter on and put the cover back on and, VOILA, PROBLEM FIXED!!!!! I NOW HAVE WATER COMING FULL FORCE FROM THE DISPENSER!!! I’m going to call GE tomorrow to ask them WHY they wouldn’t tell people about that piece of styrofoam. It’s such a simple fix; but, seeing how many other people are having the same problem, I thought I would let you all know! HOPE THIS HELPS!!! Good Luck!!!

Manually push it in until you hear a soft "bang " I had to do it few times until it started dispensing water.

Before I did what I explained above, the only time the refrigerator was dispensing water was when the old filter was on, or when there was no filter at all. I was without a filter for almost 6 months. Until I decided to give a try for the last time.

Try pushing it several times and twist it until it dispenses water. It works!

I found that after replacing the filter and running some water the pump would stop and panel would no longer respond. I would wait about 10-20 mins then I could use the water again. It took 3-5 cycles to get the water going again reliably.

Let the water run longer there is air in the line.

This happened to me too. The water dispenser and ice maker worked perfectly before I replaced the filter. I put the old one back and it still didn’t work. I checked the web and found advice on adjusting the water pressure and filling the new filter with water. (One of them said to do this for 20 minutes!) I knew water pressure wasn’t the issue because the old filter worked fine. I made sure the new filter was filled with water but that didn’t do the trick. The fact that reinserting the old one didn’t work was a clue that I didn’t follow right away.

Finally I remembered that when I removed the old filter by turning it to the left I felt a moderate amount of resistance and then it turned easily enough and came out. I figured that was just adhesion on a part that hadn’t been turned in more than a year.

Nope.

Keeping in mind that resistance that I had noticed when I removed the old filter I inserted the new one (filled with water) and after I felt the resistance I turned a bit more while being careful not to overdo it. It was like going over a small bump. Suddenly the filter turned a bit more and then seated itself. The water flowed!

It would have been nice of GE to mention this in their manual. Idiots.

Hope this helps some people who have this annoying problem.

I FIGURED OUT THE ANSWER TO NEW FILTERS NOT WORKING. SEND ME AN EMAIL at sjlevin@comline.com, if you want the answer. Could not believe what the cause was. Took me actually 10 darn years to figure this out.

We had real slow water and hollow ice cubes, replaced dual inlet valve, no change. Plastic hose on back of fridge sprang a leak… called for service as we were stumped, they offered that the water reservoir might be icing. Ok, so we got the hair dryer in there for a long while…no change in pressure. Husband ordered a water reservoir which came with a filter bypass plug ( we didn’t have with this fridge) water pressure was great! So, it must be the stupid everydrop filters (which are recommended). Happened to have a Denali brand filter for our model # so gave it a try- success…can’t imagine why other filters were so restrictive but it seems to be working now, good luck to you! This was a French door Maytag with water/ice in the door, love the thing otherwise.

I have a ge model DFE28JSHBSS and after replacing my water filter the sign for the water turned the despenser off what should I do?

I just ordered a “Water Inlet Valve” because changing the filter system did not fix the problem.

The only other reason I can see it not working is between the water inlet valve and the door tubing. But since the system was working perfectly before I changed a filter, I would bet the valve shorted out. I do not have a Ohm sensor to check it, so for $20 on Amazon, I just ordered a new one.

I fixed it! Thank you for all your thoughts and brainstorming! I placed the washer in my filter after going through all the steps above and once I did that Voila! I now have a stream of water in my dispenser. I also had foam above my filter which I removed, however that was not what worked. The washer did it and it was an easy fix for me. Thank you!!!

My Problem and solution was previously posted. I jiggled the + shaped flow valve that the water filter pushes in. Turn off and relieve water pressure before changing the water filter seems like a good idea.

The filter head assembly has a nipple sticking out in the spot that water will come into the filter. This nipple will be pushed out by the water pressure behind it to stop the water coming out when there is no filter mounted.

When you mount the filter it will push that nipple in slightly and allow the water to flow through your filter, in this process you can damage that nipple and it will not be pushed in, so water will not flow(or flow is reduced) unless you change the filter head assembly.

Solution: before changing the filter shot off the water AND eliminate the water pressure by turning on a cold water faucet.

This way your filter will not damage the nipple in the filter head assembly.

This is my issue which I have not seen a solution or idea on how to fix. My water dispenser will dispense water for a few seconds then shut off, with a quick hammering noise. I replaced the filter and this did not fix it. I then traced out where the water source is coming from and it is split off of my kitchen faucet cold water line. My kitchen faucet works fine. I discovered when I have the kitchen faucet on, my refrigerator water dispenser works perfect. This leads me to believe it is not the water filtration assembly as water is coming through fine. Is it the water inlet valve? Why will the dispenser work fine only when the faucet is on and pulling water?

UNPLUG FRIDGE FOR 30 SECONDS. Out of the many repetitive answers above, I only found this once - by Bob Wasson.

Bob! You Da Man! I tried a lot of things - that didn't work. I KNEW it had to be something simple as the cause (me improperly turning out the Replace Filter light [I followed the filter manufacturer's instructions instead of those in the manual]) the cause was simple. And P.S. To The World - The unplugging thing also worked for my printer. Thanks, Bob. And you're welcome, world.

The answer I have found out has to do with why new filters are not working. If you want the answer yourself, send me an e-mail at . The cause of the problem could not be believed at all. In reality, it took me a good ten years to figure this out.

No e mail address but i k the filter out and put on the bypass plug what causes this problem

I’ve tried pretty much all of the above, to no avail. I’ve ordered an Ice Freeze Water Line tool. Hope it works, argh!?!

• UPDATE STRAIGHT FROM A 30 YEAR GE REPAIR MAN ***** Don’t waste your time and money. If your refrigerator is in working order and the new, non-GE water filters don’t work properly, that’s because GE put in RFID tags and sensors in their newer appliances. So they purposely made it so only expensive GE filters work… and they do not disclose this info publicly so they get people frustrated enough for service calls. Super dishonest and shady business practice.

Don't believe the the twist on type GE MWF filter incorporates the RFID technology. Believe it applies to the GE inline type and XFWE GE twist on filters, 2021 and up perhaps.

GE RFID water filter

https://www.youtube.com/watch?v=v9RWohwx...

I am using XWFE filters made by GE. My fridge is only about a year old.

I finally solved my Kitchenaid KFRC704 refrigerator water filter dispensor issue. I would hve to reset the filter multiple times per day for the dispensor to work. Plus there was always a puddle of water at the filter door. It did not leak per se, just this small puddle. It seemed to be getting air into the system.

I ordered a Kenmore brand water filter 9082, it had smaller diameter O-Rings, so it was able to in further and that did the trick!. A tech had told me once that the filter needed to go in further when it was under warranty, now 5yrs later with the Kenmore brand filter, it works, no puddle, no having to reset the filter cartridge. The Every Drop filters has larger diameter O-Rings, which is a no-go.

Thank you for these suggestions.

I just had the same problem. On the suggestion of a local hero, I filed this hard plastic stem just a bit with a nail file. This allowed the filter to push all the way in and seat the valve stems properly. Go slow with the filing. Just a couple passes and then try it. Better too little than too much.
