Repair Advice:

Whirlpool Washer Owners often encounter the F23 error in Whirlpool Duet washers. This error signifies a water heating fault, commonly observed when the water temperature fails to rise above 86 degrees Fahrenheit (30 degrees Celsius) within the first 40 minutes of the cycle. Addressing this error involves a methodical approach to pinpoint the exact cause, which could range from a faulty heating element to a malfunctioning temperature sensor, or even wiring issues.

Firstly, it's crucial to inspect the wiring and connections between the control board, the heater, and the NTC (Negative Temperature Coefficient) sensor. Look for signs of corrosion, loose connections, or damaged wiring. These electrical issues, if left unresolved, can lead to inaccurate temperature readings or heating failures.

For models equipped with a water heater, the troubleshooting process involves testing the heater for continuity with an ohm/volt meter. A closed circuit in the heater’s reading indicates it is functioning correctly. In cases where the heater is operational, the focus then shifts to potential wiring problems or a defective temperature sensor.

In models without a built-in heater, the F23 error is almost invariably linked to the water temperature sensor. Testing the temperature sensor is relatively straightforward. Using the resistance chart specific to Whirlpool Duet Washers, compare the sensor's resistance reading to the corresponding temperature. Ideally, match your reading with the ambient room temperature if the washer tub is empty.

If your diagnostic points to a malfunctioning water temperature sensor (NTC) or a defective water heating element, replacement parts can be easily sourced. The parts are linked on the page below.

In summary, while the F23 error can be a signal of multiple issues, systematic testing with a reliable ohm/volt meter will lead you to the root cause, whether it’s the heater, the sensor, or wiring problems. As always, if the problem persists or you’re unsure about handling electrical components, it’s advisable to consult a professional technician for a thorough examination and repair.
