What Does Error F7 Mean?

The F7 error code on your White Westinghouse dishwasher indicates a malfunction related to the temperature sensor, which may detect over-temperature conditions. This can cause unusual noises during operation and prevent the dishwasher from draining water properly. The issue may stem from a faulty temperature sensor, heating element, or control board, leading to excessive heating or incorrect temperature readings.

Common Symptoms:

  • Dishwasher displays F7 on the control panel/LED display
  • Cycle stops or fails to proceed when F7 appears
  • Dishwasher may be heating water or detecting high water temperature

Possible Causes

  • Water over‑temperature detected by sensor (medium)
  • Faulty temperature sensor or NTC thermistor (medium)
  • Heating element or control board causing excessive heating (low)

How to Fix Error F7

DIY Fix Basic Checks and Reset

  1. Turn off and unplug or disconnect power to the dishwasher for at least 5 minutes to reset error registers.
  2. Ensure the dishwasher is connected to a cold water supply.
  3. Verify normal water supply temperature.

Technician Only Inspect Temperature Sensor and Heating System

  1. Access and test the dishwasher temperature sensor/NTC thermistor resistance with a multimeter per specification.
  2. Inspect wiring and connectors for the sensor and heating element for continuity and secure connections.
  3. Measure actual water temperature during operation to confirm whether overheating is real or a false sensor reading.
  4. Replace the temperature sensor if out of specification; if sensor is good, test heating element and control board relays.

Parts needed: NTC temperature sensor, Heating element, Wiring harness, Control board (if required)

🛑 When to Call a Pro:
  • If testing of sensors and heater components is beyond user capability.
  • If replacing the temperature sensor does not clear F7 and water overheating continues.
  • If there are signs of electrical faults or burnt wiring.
