GE Dishwasher Error Code F226

F226 on a GE dishwasher means the appliance has detected a fault on the machine control board. This is a self-reported diagnostic code, meaning the control board's internal circuitry has identified an abnormal condition within itself. The code signals that the board is not functioning correctly and will need to be replaced to restore normal operation.

Resetting the dishwasher by cutting power at the breaker for a few minutes may temporarily clear the code, but F226 indicates an internal board fault that is likely to return. Because the fault originates within the control board's own circuitry, a reset does not address the underlying hardware failure. If the code returns after a reset, board replacement is necessary.

The cost to repair F226 depends on parts and labor in your area. A replacement machine control board for a GE dishwasher typically costs between $100 and $250 for the part alone, with professional labor adding another $75 to $150 depending on local rates. DIY replacement can reduce the total cost significantly if you are comfortable working with appliance electronics.

A knowledgeable DIYer can attempt this repair by first checking that power is stable, then inspecting all wiring harness connectors at the control board for looseness or corrosion. If those checks do not resolve the fault, replacing the machine control board is the required fix. Working with dishwasher electronics requires disconnecting power at the breaker before accessing any components.

It is not recommended to continue using the dishwasher while F226 is active. A faulty control board can cause unpredictable behavior, including failure to shut off water, incorrect cycle operation, or electrical faults. Disconnect power to the unit until the repair is completed.
