GE Dishwasher Error Code F202

F202 on a GE dishwasher means the machine control board has detected a connection problem at the water inlet valve. This valve controls when water enters the dishwasher during a wash cycle. The fault can stem from a loose or corroded connector at the valve, a damaged wiring harness, or a failed control board. Inspecting the wiring at the valve is the recommended first step.

It is not recommended to continue running the dishwasher while F202 is active. A connection fault at the water inlet valve means the control board cannot reliably control the water fill, which could result in underfilling or unexpected behavior during the wash cycle. Address the fault before resuming normal use.

A reset may temporarily clear the F202 code, but the error will return if the underlying connection problem at the water inlet valve has not been resolved. Resetting the dishwasher by cutting power for a few minutes is useful for confirming whether the fault is intermittent, but it does not substitute for inspecting and correcting the wiring or replacing the control board.

Checking and reseating the wiring connector at the water inlet valve is a straightforward task that a confident DIYer can perform after disconnecting power to the appliance. If the connector and wiring appear intact, replacing the machine control board is the next step and is more complex, though still manageable with basic appliance repair experience. Always disconnect power before working on any internal components.

If the repair is simply reseating a loose connector, there is no parts cost involved. If the wiring harness needs replacement, expect parts costs in the range of $20 to $60 depending on the harness assembly. A replacement machine control board typically costs between $80 and $200 for parts alone, with additional labor costs if a technician performs the repair.
