What Does Error F8 Mean?
The F8 error code on a White Westinghouse dishwasher indicates a heating fault, meaning the water has not reached the desired temperature during the wash cycle. This can result in cycles completing with cold or lukewarm water, leading to poor cleaning performance. The issue may be caused by a malfunctioning heating element, a faulty temperature sensor, or a control board not activating the heater due to circuit logic errors.
Common Symptoms:
- Dishwasher displays F8 during or after a cycle
- Water not heating (cycles complete with cold or lukewarm water)
- Poor cleaning performance in wash cycle
Possible Causes
- Heating element malfunction (medium)
- Temperature sensor (NTC) or related circuit fault (medium)
- Control board not activating heater due to pressure or circuit logic (low)
How to Fix Error F8
DIY Fix Basic checks and reset
- Turn off and disconnect power to the dishwasher for 5–10 minutes to reset control logic.
- Ensure dishwasher is receiving hot water from the household supply.
- Run a short wash cycle to see if error returns after reset.
Technician Only Inspect and test heating system
- Measure resistance of the heating element.
- Test the temperature sensor (NTC) for correct resistance at ambient temperature.
- Inspect wiring harness and connectors from heater and sensor to the control board.
Parts needed: Heating element, Temperature sensor (NTC), Wiring harness/connectors
- If the F8 error persists after resets and basic checks
- If multimeter testing shows out‑of‑spec components
- If access to internal components is restricted or uncertain
