Fisher & Paykel Top-Load Washer Code 237: Temperature sensor continuity error

What 237 means

On Fisher & Paykel AquaSmart and EcoSmart top-load washers such as the WA37T26EW and WA42T26GW, and SmartDrive Phase 6 models like the GWL15, code 237 means the electronics picked up a continuity problem with the temperature sensor, the same as codes 10 and 40. The control cannot read water temperature reliably, so the cycle stops and the number shows.

Common causes of 237

Continuity problem in the temperature sensor circuit
Sensor connector or wiring loose
Temperature sensor failed

✓ One safe check you can try

1. Turn the washer off and unplug it for one minute. 2. Plug back in and start a short cycle. 3. Make sure the washer is in a room above freezing; cold surroundings can disturb the reading. 4. If code 237 returns, stop and book service. The sensor and wiring need meter testing.

! Why to stop there

The sensor and wiring are inside the cabinet
A continuity break needs a meter to locate
Swapping the sensor blindly may not cure a wiring cause

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.
