Fisher & Paykel Washer 237 Error Code

What 237 says

On a Phase 6 washer, 237 stands for “Temperature Sensor Error”. A continuity problem has been detected by the electronics, and in the manual it is equated with faults 10 and 41.

First suspect

Failure of the sensor itself, whether in the harness or where it connects to the thermistor. The thermistor (temperature sensor) is the part to replace.

Second suspect

The Motor controller could not obtain a temperature reading. Its connections are examined; where they look sound and the fault continues, the Motor controller is swapped. It comes last in the list.

Thermistor and continuity

A thermistor changes its electrical resistance as temperature changes, so the washer learns the water temperature from it. Continuity is the unbroken electrical path; 237 reports trouble along that path.

Owner steps

None are given. Before anyone handles the sensor wiring the washer should be powered off and its plug pulled.

Same fault, other numbers

• Code 10: the sensor circuit is open, or the surroundings are colder than -10 C.
• Code 41: the thermistor reads over 110 C, which probably means a short on the sensor line.
