GE GDF620HMJ2ES dishwasher fills with water, but then it just drains

First, I have scanned the manual and searched for this problem. So many have had this issue, but it seems not with this dishwasher type, so apologies for asking about this issue if it is already answered.

I have a GE GDF620HMJ2ES Dishwasher. I am about at my wits end with this thing! About two and a half months or so ago, I noticed that my dishes were not getting clean, and the pod was not dissolving. I diagnosed a split hose, which required me to replace the diverter, which I did. I also replaced all the other hoses as a precaution, and then I reassembled everything. The dishwasher operated as normal for about two weeks, but now I have a new issue.

The machine fills with water (adequately, I am unsure, but there is water in the box). I will take it apart, tinker with it, trying superficial things. Then it seemingly works again on a light run with nothing in itq, so I try to run a load of dishes and nada. I took it apart again today, (the door assembly and all this time) and did a deep clean, and then I again replaced the hoses.

Ran a basic wash cycle with nothing in it, worked like a charm. So then I loaded it up, put it on the usual settings (heavy, boost temp) and it filled the box and nothing. Sat for about ten minutes and then drained, almost as if it completed a cycle then pushed the water out. This has been the case numerous ttimes. If I end a/the cycle prematurely, the dishwasher just will not respond on any level (light, normal, or heavy), it will just fill, sit, drain, repeat.

I have cleaned the filters numerous times, replaced hoses and parts, the only thing left to replace would be the boards, pumps themselves, and water valve. I am genuinely at a loss as to what it could be, and I have half a mind to just replace it! Any ideas as to what my issue may be?

EXACT same issue. Well I didn't take my apart to the extent that you did, but mine fills, drains and sits just as yours. Some runs are clean, some aren't.

I just got the same issue with my Dishwasher GE GDT695SGJ2BB. It fills with water but does not start the washing process. The arms do not rotate and the dishwasher sits like that to the end of the cycle. Then it just drains and heats in the end. It drains very well, I can see it in the Garbage Disposals.

Hi @kolfild22

Check behind the kickplate (toe plate?) to see if the tech sheet is there in a plastic sleeve.

The tech sheet will show how to get into the diagnostic mode and hopefully if there is an error code displayed running the tests it may get you closer to what the problem is.

@jayeff thank you. I found it. So, I entered the ERROR MODE. I found out that my HEATED DRY and LOCK LEDS are SOLID. This means that this is a Wash Temperature error. Whish is weird. Then I entered SERVICE MODE. I did all 5 tests from the tech sheet. So I found out that I can not pass the Circulation pump test. It seems like this pump does not work. BUT I could pass the DRAIN PUMP test. Now I am confused. I thought that Drain Pump and Circulation Pump - is ONE pump.

完成的

so, I pull out DW from the cabinet and put it on the side. I disconnected the power wire that goes to the circulation pump and also checked contacts. I remove the cover from the circulation pump and I tried to rotate the rotor. It was moving slow. After that, I return everything back and Install DW in its place. I did a test and the DW is working. I guess, there was something with contacts.

Sounds like the drain pump solenoid is getting stuck in the open setting

Drain Pump

The drain pump uses an impeller to force water through the drain hose. If the drain pump motor is not working, the dishwasher won’t drain. To determine if the drain pump is defective, check the pump motor for continuity using a multimeter. If the motor does not have continuity, or if is getting power but won’t run, replace the drain pump. Drain pumps are not repairable—if the drain pump is defective, you must replace it.

Hi @kolfild22

Have you checked the temperature of the water supply to the dishwasher?

According to p.5 of the installation manual it says to “Adjust water heater for 120°F to 140°F temperature”.

There is also a heater element- part #101 body parts diagram which is used to raise the temperature but this can only raise it by some 20-40F.

I cannot find a temperature sensor or thermostat shown in the parts list so I’m not sure how the control board knows whether the temperature is correct or not or whether to turn on the heater also unless the heater is merely a ‘timed” event so to speak only when Heated dry or Wash Temp boost or Sani is selected. Maybe the tech sheet mentions about the water temperature?

Perhaps the heater element is checked to make sure that it is OK. Try using an Ohmmeter (disconnect power from the dishwasher) and check that the heater element has continuity and is not open circuit. Don’t know the resistance value but usually they are between 25-100 Ohms and definitely not open circuit.

Looking at the parts for your model there are two pumps, the circulation pump -part #310 - sump and motor mechanism diagram and the drain pump - part #325 - sump and motor mechanism diagram

Check if there is power getting to the circulation pump and if so check that the pump motor winding has continuity.

There are other suppliers online that may suit you better. This was only to show you the parts and their location. Just search for GDT695SGJ2BB parts

I have a blanco dishwasher

This has happened twice and both times it’s been the capacitor on the main wash circulation pump

Replace the capacitor and away it goes for another year or so

Impeller was jammed. Rotating it by hand usually will break it loose and then you're good to go
