How to Fix / Troubleshooting
Safety first: Verify that the outlet is not live before touching the plug or cord.
Steps:
- 1. Check outlet: Test the wall socket with another appliance to confirm power is available.
- 2. Inspect power cord: Look for visible damage. If damaged, have the cord replaced by a qualified technician.
- 3. Check household breaker: Reset any tripped breaker or replace blown fuses in your electrical panel.
- 4. Access main PCB: If the outlet and cord are fine, the internal fuse on the main control board may be blown. This usually indicates another fault and should be checked by a technician.
- 5. Replace main control board: If the board is not supplying any power to the display or lights, replace it with the correct V-ZUG PCB.
Warning: Do not bypass or replace internal fuses with higher-rated ones; this is a fire hazard.
