How to Fix / Troubleshooting

Safety first: Ensure the unit is unplugged before opening any covers.

  • Check outlet and fuse: Test the wall socket with another appliance. Replace the plug fuse with the correct rating if blown.
  • Inspect power cord: Look for visible damage along the power cable. If damaged, replace the entire cord set.
  • Test power switch: Access the main power switch and test for continuity when switched on. Replace if faulty.
  • Check control PCB: If power reaches the PCB but there are no lights or response, the main control PCB may be defective and require replacement.
