Possible Causes

Blown internal fuse on control board, Faulty mains cable, Loose connection at terminal block

How to Fix / Troubleshooting

Safety first: Ensure the outlet is safe and not overloaded.

Steps:

  • Check outlet and breaker: Test the socket with another device and verify the circuit breaker or fuse has not tripped.
  • Inspect mains cable: Look for cuts, kinks, or burn marks along the Liebherr power cord.
  • Access terminal block: With power disconnected, open the rear or top electronics cover and check that the mains wires are firmly secured in the terminal block.

Remedy: If the external supply is good and connections are secure, an internal fuse or the control board may have failed. Replacement of the control board or fuse should be done by a qualified technician.
