Ge WD21X32163 Electronic Control Board OEM Part

I used the video online to take it apart, as it turned out the first part sent, didn’t fit, Appliance Parts Pro took my return, and quickly sent the right part. I am a 79 year old widow, and was able to repair it myself with the online video.

Fix went fine, had to pull the dishwasher out to replace flood switch control board was very easy to replace, and fixed the problem.

Replaced the control board on bottom of machine

I replaced the control board. It is very easy. You can do this without moving the dishwasher. You will need to disconnect the power, and the electrical box to move it out of the way. Remove the plug ins and a couple of screws holding the box connected to the control board. Once this is done, the plastic box holding the control board can be pulled down to access. I suggest watching a couple of YouTube videos.

Heating element not working. Troubleshot using Error and Service Modes. No error codes were returned. Heating element did not heat up during Service Mode. Checked heating element with ohm meter. Continuity and resistance (ohms) was within range (around 16.5 ohms…I didn’t take note of actual reading). Checked voltage during Service Mode at the heating element using a volt meter. Never saw voltage at heating element. Checked Flood Switch with ohm meter. It worked as expected. Ordered and replaced the Control Board. Still no heat. Located the Thermal Cut Out (TCO) on the right underside of the tub about 12 inches from the front of the tub. It was tripped. Pushed the reset button on it and ran Service Mode again. Burnt my finger on the heating element. I was happy about that. :) Dishwasher is working perfectly now. According to all I read. If the TCO trips the Control Board should be replaced. So I don’t feel I replaced the Control Board needlessly.
