Fisher & Paykel Washer, Dishwasher, Oven Error Code 37

Error code 37 indicates a blocked pump fault. The appliance control system has detected that the drain pump is unable to operate correctly, most likely because debris or a foreign object is obstructing the impeller or drain path. The appliance stops the cycle to prevent pump motor damage or flooding. Clearing the blockage from the pump filter or housing typically resolves the error.

A power reset may clear the error code temporarily, but if the underlying blockage has not been removed, the error will return as soon as the appliance attempts to drain again. The physical cause must be addressed before a reset will produce a lasting result. After clearing the blockage, a reset or restart of the cycle should allow normal operation to resume.

If the fault is simply a clogged filter or foreign object blockage, the repair can cost nothing beyond your time. If the pump impeller is damaged or the pump motor has burned out and requires replacement, parts and labor costs typically range from $150 to $400 depending on the specific appliance model and your location. Getting a diagnostic assessment from a qualified technician can help determine whether the pump needs replacement before purchasing parts.

Start by locating and removing the pump filter, which is usually accessible behind a small panel at the front base of the appliance. Clean the filter and inspect the filter cavity for any foreign objects. Also check the drain hose for kinks or obstructions. If the pump impeller is damaged or the motor has failed after prolonged blockage, the pump assembly will need to be replaced.

The error itself is a protective measure, so the appliance stopping is the safe response to a blocked pump. However, if the appliance is halted mid-cycle with water inside, there is a risk of water sitting stagnant or leaking if the door or lid is forced open. Do not attempt to manually force drainage by tipping the appliance without first checking and clearing the pump filter to avoid water damage or injury.
