Step-by-step troubleshooting
- Check Power SupplyDo: Verify the washer is plugged in and the circuit breaker hasn't tripped.Observe: Power indicator lights or motor hum when on.Means: Power is connected properly.Next: If power is off, restore it and try again.
- Inspect Water SupplyDo: Ensure both hot and cold water valves are fully open.Observe: Water flows freely from the hoses when turned on.Means: Water supply is not blocked.Next: If water is restricted, open the valves fully.
- Close and Lock Lid/DoorDo: Make sure the lid or door is fully closed and latched.Observe: The door lock engages with a click or light indicator.Means: The washer detects the door is secure.Next: If the door won't lock, check for obstructions or a faulty latch.
- Reset the WasherDo: Unplug the washer for 1 minute, then plug it back in.Observe: Control panel resets and displays normal.Means: A temporary glitch may be resolved.Next: Try starting the cycle again after the reset.
- Check for Error CodesDo: Look at the control panel for any displayed error codes.Observe: Error codes or symbols appear on the display.Means: The washer has a specific issue to address.Next: Consult the manual for the error code meaning and solution.
- Test the Start ButtonDo: Press the start button multiple times to ensure it's functioning.Observe: The button clicks or the panel responds.Means: The start button is working correctly.Next: If unresponsive, the control board may need inspection.
Common causes
| Cause | Likelihood | Difficulty | Part often needed |
|---|---|---|---|
