Whirlpool Washer - F48 Error Code

Water temperature out of expected range.

Meaning

Water temperature out of expected range.

The F48 error indicates that the washer has detected a water temperature that is outside the expected range for the selected cycle. Whirlpool Cabrio and HE washers monitor water temperature using an NTC thermistor. If the temperature is too high, too low, or changes too rapidly, the washer triggers F48 to prevent fabric damage and incorrect cycle performance. This error is common when the temperature sensor is failing or when hot and cold water supplies are reversed.

Symptoms

  • Washer stops early in the cycle
  • Water temperature seems incorrect
  • F48 appears shortly after filling
  • Washer refuses to start certain cycles

Causes

  • Faulty temperature sensor
  • Reversed hot and cold water hoses
