Fisher & Paykel Washer Error Code #37

Error code #37 on a Fisher & Paykel washer indicates a pump blocked error, meaning the machine attempted to drain but was unable to empty the drum within the expected timeframe. The drain pump is responsible for expelling wash and rinse water at the end of each cycle. When the control detects that water remains in the tub after the pump has run for its allotted time, it triggers this fault code and halts the cycle to prevent overflow or mechanical damage.

The most common sources of this fault fall into two categories: physical blockages and installation issues. Blockages can occur inside the pump itself, where small items like coins, lint, buttons, or debris collect and jam the impeller. The drain hose is another frequent trouble point, as it can become kinked, crushed against a wall, or obstructed by a buildup of debris inside the hose. Installation-related causes include a drain hose outlet positioned too high. Fisher & Paykel specifies a maximum drain height of 7 feet. Exceeding this creates back-pressure that the pump cannot overcome.

Diagnosing this code begins with a visual inspection of the drain hose routing to confirm it is not kinked or crushed and that the standpipe or sink connection is within the 7-foot height limit. If the hose checks out, the next step is accessing and inspecting the pump filter or trap for debris. If the impeller is jammed or the pump motor has failed electrically, the pump assembly will need to be tested or replaced. Water left in the drum should be drained manually before any inspection work begins.
