Fisher & Paykel Washer Dishwasher Oven Error Code 37

Error code 37 on Fisher & Paykel appliances indicates a blocked pump condition. This fault is triggered when the pump motor encounters resistance beyond its normal operating parameters, typically because debris, foreign objects, or buildup are preventing the impeller from spinning freely. The appliance control board monitors pump current draw and rotation feedback, and when the pump cannot complete its cycle within expected thresholds, it flags the blocked pump error to protect the motor from damage.

The pump system is responsible for evacuating water from the wash tub or dishwasher cavity at the appropriate points in the cycle. When blockages occur, water cannot drain efficiently, and the appliance halts operation to avoid flooding or mechanical failure. Common sources of blockage include lint accumulation, food debris, broken glass, coins, or small garment items such as socks that have bypassed the drum seal and entered the pump housing or drain filter.

Diagnosing error 37 involves physically inspecting and clearing the pump filter and drain path before assuming the pump itself has failed. In many cases, removing the blockage fully resolves the fault. If the pump impeller remains seized or damaged after clearing debris, or if the pump motor has burned out from prolonged strain, component replacement will be necessary. The drain hose and standpipe should also be checked for kinks or clogs that create back-pressure against the pump.
