KitchenAid Dishwasher Error Code F8E2

F8E2 indicates an electrical problem in the fill valve circuit. The control board has detected an open circuit condition, which can be caused by a loose wiring connection, a failed fill valve solenoid, a blown fuse on the control board, or a fault in the control board's fill valve drive circuit. It is an electrical fault, not a water supply or pressure issue.

You should not continue running the dishwasher while this code is active. An open circuit in the fill valve system means the appliance may not fill correctly, and running a cycle without proper water flow can damage the pump, heating element, or other components. Disconnect power and address the fault before resuming use.

A power reset may temporarily clear the code, but if the underlying electrical fault in the fill valve circuit is still present, the F8E2 code will return once the dishwasher attempts to fill. The only way to permanently clear the code is to diagnose and repair the specific open circuit or failed component causing it.

Some steps are accessible to a knowledgeable DIYer, starting with unplugging the dishwasher and inspecting the wiring connections in the fill valve circuit for looseness or corrosion. However, testing solenoid resistance, identifying a blown board fuse, or diagnosing a faulty drive circuit requires a multimeter and comfort working around appliance components. If those checks are beyond your comfort level, a qualified technician should handle the diagnosis.

Repair costs vary depending on which component has failed. A fill valve replacement typically runs in the range of $80 to $200 including parts and labor, while a control board replacement can range from $200 to $400 or more depending on the model. A wiring repair or connector fix is generally on the lower end of the cost spectrum.
