Questions & Answers

For Ge Dishwasher Timer Control (Part Number: OEM21648936)

Carlos for Model Number GSD3300K55BB

Hello- the timer was sticking on my dishwasher, and the solenoid melted. I replaced the timer and solenoid, the timer part number is WD21X33641. After replacement, upon testing, the solenoid only engages for a short time, and it doesn't drain the last few cups of water from the dishwasher. I also noticed that the machine seems to be 'washing' while the solenoid is in the drain position. At first I thought I had the wrong timer. Please help. Many thanks! Carlos from Crossville.

Hello Carlos, thank you for contacting APP, I would suspect this as an issue with the Current Sensing Module WD21X23836 or damaged wiring somewhere in the unit not carrying the load very well and tripping the current sensing module. You may try pulling the unit out to access the CSM and take some voltage readings on the incoming and outgoing voltage to see if the voltage is dropping out when the issue occurs with a multimeter if you are comfortable testing live voltage. The Black and White wires should have 120V AC at all times that the unit is connected to power. If you are seeing this voltage drop out under load there may be a connection issue at the terminal block, a power cord issue, or even a source wiring/electrical issue from the home. The Red and White with Orange tracer should also have voltage at all times that the unit is connected to power. If voltage is staying steady on the incoming black and white but is dropping out on the red and white w/ orange when the unit is experiencing the issue then either the CSM is bad or something is causing it to cut out.

Russell, You will want to check the dispenser timer lever and make sure that it is not stuck in a position that will keep the latch from latching.

Jim, the flood switch WD21X479 and float WD12X445 will need to be checked to ensure that there are no obstructions keeping the float in the up position as well as testing to ensure that the switch has continuity when pressed (with voltage supply off). If these test good, then the most likely issue would be in the timer WD21X33641.

Tim for Model Number GSC3500D35WW

Dishwasher shows no sign of life. It just stopped toward the end of the cycle and now it will not do anything. My dishwasher has 2 door switches. I have tested them both and they seem to be fine. My AC voltage Detector says that I have power in the wires coming to the door switches when machine is plugged into the wall outlet. At the wall outlet I have the proper voltage via my multimeter. Does that only leave the timer as the possible problem? Is there any way to test the timer? This machine is only 2 years old. Thanks

Tim, You could check to make sure that you are getting power to the timer but based on the information that was provided I sounds like the timer would be the issue with the unit.
