What Does Error F6 Mean?

The Westinghouse dishwasher F6 error indicates a fault in the temperature sensor (NTC) circuit, often leading to incorrect water temperature readings. This malfunction may cause the dishwasher to stop its cycle and display the F6 code, usually accompanied by unusual noises. If the temperature sensor or its wiring is faulty, it may prevent the main PCB from receiving accurate temperature data, causing performance issues.

Common Symptoms:

  • Dishwasher stops cycle and displays F6
  • Possible incorrect water temperature readings or inability to measure temperature

Possible Causes

  • Faulty temperature sensor (NTC) (medium)
  • Open or broken wiring/connectors in temperature sensing circuit (medium)
  • Main PCB not receiving temperature data due to upstream fault (low)

How to Fix Error F6

DIY Fix Check simple connections and reset

  1. Turn off and unplug the dishwasher.
  2. Check that the wiring connectors to the temperature sensor are firmly seated.
  3. Power on and run a test cycle to see if error persists.

Technician Only Test and replace temperature sensor or wiring

  1. Disconnect power to the dishwasher.
  2. Access the temperature sensor (NTC) and wiring harness.
  3. Measure NTC resistance at ambient temperature.
  4. Check continuity of wiring back to main PCB.
  5. Replace sensor if out of spec or repair wiring as needed.
  6. Verify proper operation after reassembly.

Parts needed: Temperature sensor (NTC), Wiring harness

🛑 When to Call a Pro:
