Fisher & Paykel Washer Error Code 237

Error code 237 means the washer's electronics have detected a continuity problem in the temperature sensor circuit. This is the same underlying fault as codes 10 and 41 (Phase 6). The control board cannot get a valid signal from the thermistor, so the machine stops to avoid running a cycle without proper temperature control. The thermistor or its wiring circuit needs to be inspected and likely replaced.

You should not continue running the washer while error 237 is active. Without a functioning temperature sensor, the machine cannot regulate water temperature correctly, which could result in improper washing or potential damage to fabrics. The washer will typically stop operation on its own when this fault is detected to prevent those outcomes.

If only the thermistor needs replacement, parts typically cost in the range of $15 to $60 depending on availability, with labor adding $75 to $150 if a technician performs the repair. If the wiring harness or control board is also involved, total repair costs can rise to $150 to $400 or more. Getting a diagnostic assessment first helps clarify exactly which components need replacement before committing to a repair.

A knowledgeable DIYer can start by inspecting the thermistor wiring harness and connectors for obvious damage or disconnection. If the wiring looks intact, testing the thermistor with a multimeter for continuity will confirm whether the sensor itself has failed. Replacing the thermistor is a relatively straightforward repair, but if the control board is involved, professional service is recommended.

A power reset may temporarily clear the error display, but the fault will return as soon as the machine attempts to read the thermistor and detects the same continuity problem. Because code 237 points to a hardware failure in the sensor circuit, a reset does not fix the underlying issue. The thermistor or related wiring must be repaired or replaced for the code to clear permanently.
