GE Dishwasher Error Code F2

F2 on a GE dishwasher means the User Interface control board and the machine control board have lost communication with each other. The dishwasher stops operating when this fault is detected to prevent unpredictable behavior. The cause is most often a loose or corroded wiring connector, though a failed control board is also possible.

A reset, such as cutting power at the breaker for a few minutes, may temporarily clear the F2 code, but the error will return if the underlying wiring or board issue is not corrected. A reset is a useful first step to confirm whether the fault is intermittent, but it is not a repair. Persistent F2 errors require physical inspection of the communication circuit.

If the fix is simply reseating a loose connector, the cost is limited to a service call fee, typically in the range of $75 to $150 depending on your area. If the UI board requires replacement, parts and labor usually run between $150 and $300. A machine control board replacement tends to cost more, often ranging from $200 to $400 or higher, depending on parts availability and labor rates.

If you are comfortable working with appliance electronics, you can start by disconnecting power and inspecting the wiring harness connections between the two control boards inside the door panel. Reseating loose connectors or cleaning corroded pins sometimes resolves the fault without any part replacement. If the wiring checks out, board replacement is best handled by a technician familiar with GE dishwasher diagnostics.

No, the dishwasher will not operate normally with an active F2 fault because the two control boards are not communicating. Attempting to run a cycle in this state is not productive and the machine will typically halt or refuse to start. Resolve the communication fault before returning the appliance to regular use.
