How to Fix / Troubleshooting
Safety: Turn off power before testing heater circuits.
- Run a hot cycle: After 15–20 minutes of a wash cycle, open the door carefully and check if the water is hot. If not, suspect a heating issue.
- Inspect wiring: Access the heater area and check for burned or loose connections.
- Test heater: Use a multimeter to measure resistance across the heater terminals. Replace the heater if open or shorted.
- Check NTC sensor: Verify the temperature sensor resistance is within specification. Replace if faulty.
- If components test good: The control board may not be energizing the heater and likely needs replacement.
