Whirlpool Washer - F23 Error Code
Heater failure detected.
Meaning
Heater failure detected.
The F23 error indicates that the washer’s heating element or temperature regulation system is not functioning correctly. Whirlpool Duet washers use a heater to maintain water temperature during certain cycles. If the control board detects that the heater is not drawing current, is shorted, or is not raising water temperature as expected, the washer triggers F23. This error is common when the heater burns out, wiring becomes loose, or the temperature sensor fails.

Model-Specific Notes
On Duet models, the heater is mounted at the bottom of the tub and is prone to mineral buildup, which can cause overheating and F23 errors.
