Fisher & Paykel Washer Error Code #37

Error code #37 means the washer detected a pump blocked condition, specifically that the machine was unable to drain the water out of the drum within the expected time. The control monitors the drain cycle and triggers this code when it determines that water is still present after the pump has run. The fault points to a blockage in the pump, filter, or drain hose, or a drain hose installed at a height greater than 7 feet.

You should not continue running the washer while this error is active. The machine halts the cycle specifically because water has not drained, and forcing additional cycles can stress the pump motor further or cause water to sit in the drum for extended periods. Drain any standing water manually before performing inspections to avoid spills and reduce the risk of mold or mildew.

If the fix involves only clearing a blocked pump filter or repositioning a kinked drain hose, there may be little to no parts cost involved. If the drain pump motor has failed and needs replacement, parts and labor costs typically range from around $150 to $350 depending on the part price and local labor rates. Having a technician diagnose the fault first can help avoid replacing components that do not need to be changed.

Start by inspecting the drain hose for kinks, crushing, or an outlet height exceeding 7 feet and correct any issues found. Next, locate and clean the pump filter, removing any lint, coins, or debris blocking the impeller. If both of those checks pass, verify that the household drain or standpipe is not clogged. If the pump still does not operate correctly after clearing all blockages, the pump motor may need to be tested and replaced.

Resetting the machine may clear the displayed code temporarily, but the error will return if the underlying blockage or installation problem is not resolved. The root cause, whether a blocked pump, kinked hose, or improper drain height, must be corrected before the washer will complete a drain cycle without faulting again.
