How to Fix / Troubleshooting
Safety: Unplug the unit before removing panels.
- Check door switch: Verify the door switch actuates fully when the door closes. Test continuity and replace if it does not change state.
- Reset control: Turn the unit off, unplug for 5 minutes, then restore power and turn on. Some models require holding the power button for several seconds to start.
- Inspect control board: Look for burnt or stuck relays. If relays do not click when a cycle should start, the board may be defective.
- Replace user interface: If buttons do not respond or LEDs behave erratically, the user interface board may need replacement.
