GE Dishwasher Control Board (WD21X22276)

The GE Dishwasher Control Board is the main electronic brain of your dishwasher, receiving input from the control panel and sending signals to components like the pump, motor, water valve, and heating element to carry out each wash cycle. It coordinates timing, water temperature, and drainage so every part of the cycle runs in the right order and for the right duration.

A GE Dishwasher Control Board can fail due to power surges, moisture exposure, heat damage, or simply normal wear over years of use. When the board stops functioning correctly, it may lose the ability to send accurate signals, causing cycles to behave erratically or preventing the dishwasher from operating at all.

Watch for these symptoms to determine if the control board may need to be replaced:

- Dishwasher does not start or respond when a cycle is selected

- Cycle stops partway through and does not resume

- Buttons or controls appear to work but the dishwasher takes no action

- Dishwasher runs continuously without stopping at the end of a cycle

- Error codes appear on the display that cannot be cleared

- Certain functions such as drying or draining no longer work

- Display is blank or shows garbled information even when power is on
