Dishes come out cool, wet and filmy, with undissolved detergent left in the cup.

What does KitchenAid F3E1 mean?

The wash water did not reach the required temperature within the allotted time. KitchenAid dishwashers heat water to 120–140°F for optimal cleaning; without this, detergent does not dissolve properly.

What causes KitchenAid F3E1?

  • Failed heating element
  • Failed thermistor (water temperature sensor)
  • Low incoming water temperature (verify hot water supply line is actually hot)
  • Control board not activating the heating circuit

How to fix KitchenAid F3E1 yourself

  1. 1 Run hot water at the kitchen sink until it's hot to the touch before starting the dishwasher — this ensures the first fill is at temperature.
  2. 2 Reset by powering off at the circuit breaker for 5 minutes.
  3. 3 Check that the hot water supply line (usually under the sink) connects to the dishwasher, not the cold line — misconnection is rare but happens.
