LG WM2487HWM won't drain, OE error appears. Drain pump was replaced.

So I got the drain problem message (OE) and I ended up replacing the drain pump (even though ad someone else mentioned there are no moving parts, therefore this part is not likely to go bad). My washer seemed fine after a couple weeks but then I got the message again. I checked all the hoses and they were all clear. What I did notice was the pump was turning on and water seemed to be expelled so the pump seemed to be operating as it should. After thinking about it for a bit it seemed to me that the washer thought there was still water in the tub. I found that there is a pressure sensor that is used to determine water level. I unplugged it and blew it out then the washer worked fine after. I'll keep an eye out to see if the same problem pops up again. I may end up getting a new pressure sensor if it does. I hope my experiences can help others fix theirs.

If you're getting OE code on your LG wash machine don't replace the pump. Most likely it's fine. Take it out and take the pump off the housing and then try the impeller out of the housing and clean out the housing and the impeller shaft. Mine was full of muck. Sometimes it would work sometimes it wouldn't and I noticed when I took the pump out of the machine the impeller spun with resistance. After I clean it it spun freely like a top. My wash machine works perfect again. $0 invested about an hour and a half at a time.

Pcb Assembly is the next item I would check if your not getting 120v to the drain motor

Update, nine months later in my washing machine is still working perfectly. Don't go wasting money on buying parts. take the pump out and clean it. The motor itself doesn't go bad there's no moving Parts. It's a magnetic motor with an impeller. Just take the impeller apart clean it up, relube the shaft clean out the hole that it sits in and you'll be good to go! It's a cakewalk. I probably had about an hour into my repair. The hard part is taking the gasket off and putting it back on but I've done that before to replace it. They make a special tool for that gasket but if you're patient you can use needle nose.

After running the tub clean mode and drain and spin to no avail, LG’s customer service has told me to buy washer cleaner tablets and run 5 cycles in a row of the tub clean mode. Strange, because those say they’re for dirty or smelly tubs, and mine is neither and only 2 years old. They arrive tomorrow so I suppose I’ll see.

I did this over two years ago am I washing machine is still running just fine. It's just a dirty impeller for the pump. The pump itself has no moving Parts but the impeller. It's a magnetic impeller. It's a very simple job if you just take a little time to figure it out.

I have an LG machine WD13020D or 12020D (on manual). My husband has removed the drain pump but doesn't remember which way the black and brown wires went to reconnect. Can anyone help?

First look for the simple things.

Try to turn the pump impeller inside the pump after you've removed the drain filter. If it's stiff or jammed then look closely with a torch/flashlight into the pump for anything like string or a rubber band that may be preventing the impeller from turning. If you spot such just fish it out with a pliers or tweezers and see if the impeller turns freely.

If I had done this today I'd have saved all the work of removing and reinstalling my pump.

Just replaced my pump only for the new pump to fail on the first load.

I'd already somewhat satisfied myself that the hoses were clear. I used a shop vac to pull the water out of the tub, forward and backwards through the drain hose, etc. But one hose, the little rubber drain hose, wasn't flowing. I used compressed air to clear it and a bunch of sand and small debris came out. Very dirty inside.

New motor didn't feel smooth turning so, it being dead anyway I disassembled it and found that the permanent magnet had cracked, leaving ferous splinters which jammed up the works. also the permanent magnets cavity its was full of water.

So, IDK if i got a bad part or the sand would sneak down from the little drain hose when the chamber was flooded and jam up the works. Chamber appeared clean when i took apart the first once but right now that's what I'm suspecting.

New part in a few days, we shall see.

Moral: probably a good idea to periodically drain that little rubber drain hose as preventive maintenance!

I'm now guessing
