How to Fix / Troubleshooting

Safety first: Unplug the appliance. Compressor and inverter circuits carry dangerous voltages.

Steps:

  • 1. Listen for compressor: With power applied (before unplugging), note whether the compressor attempts to start or remains silent.
  • 2. Inspect wiring: After unplugging, remove rear cover and check harness from main PCB to compressor or inverter module for damage.
  • 3. Check inverter module (if fitted): Look for burn marks or a burnt smell. Do not open sealed modules.
  • 4. Basic reset: Leave unplugged for 10 minutes, then reconnect and observe if E5 clears temporarily.

Important: Detailed diagnosis of inverter and compressor windings requires specialized tools. Contact a Liebherr service technician for further testing and replacement.
