Pamela September 22, 2024 for Model Number GDF520PGJ2BB Dishwasher first started with water left in bottom. Cleaned out hoses little debris found. Changed out pump worked a few days he went back to original pump it worked again. Started to not complete the cycle and it again doesn’t pump all water out but dishes were clean. Changed door latch on tub side it worked two days and stopped. It now chirps 3x door open or closed does not start. Any suggestions?
1 Answer Pamela, Using the tech sheet packaged with your machine, start the service mode and check for any error codes. Also, check the service LED on the control board. Read More...
Tracy August 27, 2023 for Model Number GDF620HMJ2ES I can put the unit in service mode, but no devices turn on. You can cycle through all tests and none turn on. There is no led on the board lit up. This has happened before and one day it just started working again. When doing test there is no voltage applied to drain or circ pump. The panel however works and the 5v test location on board registers 5v. Not sure what else to test on this board. I feel its broken. If you do start a cycle the start button just starts blinking. Do I need a new board or is there something else I can test?
1 Answer Tracy, Based on the fact that the control board is getting power to it but the unit will not come on and the start button flashes when trying to select a cycle, check the door switch first to make sure that is good and if it is then this will be a faulty main control board. Read More...
Greg July 24, 2023 for Model Number GDF620HMJ2ES I shut the door, the control panel lights up, I select my wash, hit START, then I get 3 beeps and nothing happens. Suggestions?
1 Answer Hello Greg, either the main board did not see the door fully closed by the latch or there may be a wiring problem in the door wire harness that connects the U/I board to the main board under the dishwasher, also there is a service LED light on the man board that will flash a fault code if there is one, count the flashes in 3 sec duration.

Todd April 30, 2023 for Model Number GDT635HSJ2SS I have a dishwasher that starts by draining as usual, then makes a ticking sound for a few seconds, then the draining starts again. This cycle goes on, over and over. Is there a way to test the control board? I have removed it from the machine and it has no obvious problem.
1 Answer Todd, Check the LED on the main control board under the unit and see the sequence that it is flashing. Then using the tech sheet check to see if there is an error based on the flash pattern. Read More...
Al March 23, 2023 for Model Number GDF620HGJ2BB Dishwasher would not start. Power cycling the dishwasher would get it working again but it lasted shorter and shorter times until that didn't work anymore. Replaced the UI board which didn't help and then replaced the main control board which also didn't fix it. No power at all to display or buttons. Service light on Main control board is solid green with both original and new main board - which isn't one of the listed choices on the service information sheet. (everything listed is flashing). . Thank you.
1 Answer Hello AL, likely the wire harness in the door WD21X22916 that connects the boards is coming apart based on the parts replaced and the symptoms you have described. Read More...
Joe February 10, 2023 for Model Number GDT545PSJ2SS I have a dishwasher that will not start due to the door sensor not acknowledging being closed. I changed the door latch sensor already but still not working. After further research, I see it could be either the main control board or the user interface. How can I tell which is defective?
1 Answer Joe, Thanks for the question!!! The door switch is wired directly to the main control WD21X24900C. If the display is not lighting up you can test for voltage to the user interface WD21X31910. The voltage supplied is 13.5vdc on pins 1 and 2 on J401 connector of the user interface. If voltage is present then the UI is faulty. If you get no voltage you will want to check the wires and trace back to the main board and check to see where the voltage is lost. If no voltage is coming out of the main board it would need to be replaced. Read More...
Rick December 21, 2022 for Model Number GE DISHWASHER I bought a new GE WD21X24900C to replace WD21X23096, do you want the old board? As a core/deposit?
1 Answer Rick, for a control with a return core label on the packaging, you will need to ship the part to AppliancePartsPros.com Returns Center 3771 Newburg Road Louisville, KY 40218. Be sure to include a copy of the invoice inside the box with “Core Return” written on it. Read More...
Rachel November 26, 2022 for Model Number DDT700SMN0ES I was getting an H2O error every time we tried to run the dishwasher. I replaced the inlet control valve and now I don’t get the H2O error anymore however the washer just stops at a random part of the cycle. Sometimes after 1-2 minutes and sometimes after 30-40 minutes. There is no error code or beeping when it stops. No error code when in service mode. I turned off power to the units to reset the control board. Does this sound like control board should be replaced?
1 Answer Rachel, The first thing to check if the power shuts off completely will be the power supply to make sure that there is a good connection. If this is good then yes, it sounds like the control board would be the issue. Read More...
John October 30, 2022 for Model Number GDT545PSJ2SS dishwasher What is the difference between control board #WD21X24900C and #WD21X24900 dishwasher control boards. Based on my research, they appear interchangeable. Is this correct?
Steven August 22, 2022 for Model Number GDF620HMJ2ES All lights on Interface working. Lights do not flash when door open however it will cancel out by holding in start button. Washer will not start though. Have changed door switch. Is this control board?
1 Answer Steven, This issue does sound like it would be a faulty control board that is causing the unit to not start. Read More...
