Possible Causes
Failed low-voltage power supply on main PCB, Shorted component on control board, Loose display/control panel ribbon cable
How to Fix / Troubleshooting
Safety first: Unplug the unit before removing any covers. Do not touch exposed circuitry while plugged in.
- Outlet check: Verify the wall outlet is working by plugging in another appliance. Avoid using loose or damaged extension cords.
- Inspect control panel connection: Remove the top or front panel (depending on model) to access the control PCB. Ensure the ribbon cable between the display/touch panel and main board is fully seated.
- Look for moisture: If steam has entered the control area, allow the unit to dry for 24 hours in a warm, dry place before retesting.
- Board damage: If you see burnt components, bulging capacitors, or cracked solder joints on the main PCB, the board will need replacement. Component-level repair is not recommended for most users.
