How to Fix / Troubleshooting

Safety: Ensure the appliance is unplugged before opening any covers. Mains voltages are lethal.

  • Check outlet and fuse: Test the wall socket with another appliance. Check and replace the plug fuse with the correct rating if blown.
  • Inspect mains cable: Look for cuts or damage along the power cord. Replace if compromised.
  • Check mains filter: Remove the top or rear panel to access the mains filter module where the power cord enters. Look for burn marks or bulging components. Replace the filter if damaged.
  • Power switch and PCB: Verify the on/off switch (if fitted) operates correctly. If power reaches the PCB but there is no response, the board's low-voltage power supply may have failed and the PCB will need replacement.
