How to Fix / Troubleshooting

Safety first: Do not repeatedly reset the RCD without finding the cause. Unplug the refrigerator.

Steps:

  • 1. Inspect power cord: Check for cuts or crushed sections that may expose conductors.
  • 2. Allow drying time: If the issue started after defrosting or cleaning, leave the appliance unplugged for 24 hours to allow moisture to evaporate.
  • 3. Visual inspection inside: Look for signs of water near the defrost heater, fan motors, or wiring.
  • 4. Professional testing: Earth leakage faults require insulation resistance testing and component isolation, which should be performed by a qualified V-ZUG technician.

Warning: Continued use with earth leakage is dangerous; do not attempt to bypass safety devices.
