Fisher & Paykel Dishwasher Error Code F52

F52 on a Fisher & Paykel dishwasher means the control board has detected a lid motor undercurrent condition, meaning the lid motor is drawing less current than expected. This signals a problem with the electrical supply to the motor, the motor itself, or the wiring connecting them. The dishwasher will stop operating until the fault is cleared.

A reset may temporarily clear the F52 code, but if the underlying cause, such as a loose connector, corroded pins, or a failing motor, is not addressed, the fault will return as soon as the lid motor is activated again. A reset alone is not a repair and should be used only as a diagnostic step to confirm whether the fault is persistent.

Repair costs vary depending on the root cause. If the fix is simply reseating or cleaning a connector, the cost may be limited to a service call fee, typically in the range of $80 to $150. If the lid motor needs replacement, parts and labor combined can range from $150 to $350 or more depending on your location and the technician's rates. A control board replacement, if needed, would be at the higher end of that range or beyond.

The first diagnostic step, checking that the lid motor harness is securely connected and inspecting for corrosion or visible damage, is something a knowledgeable DIYer can handle safely with the dishwasher unplugged. If the harness is fine and the motor or control board needs to be replaced, most homeowners will want to call a qualified technician, as those repairs involve disassembling internal components.

You should not continue running the dishwasher while the F52 fault is active. The error indicates a problem with the lid motor circuit that could involve damaged wiring or a failing motor. Continuing to operate the appliance risks further damage to electrical components and could pose a safety hazard if arcing or wiring damage is involved.
