How to Fix / Troubleshooting
Safety first: Only qualified persons should work on live electrical circuits. Always unplug before opening panels.
- Check outlet and fuse: Test the wall socket with another appliance. Check the household fuse or breaker.
- Inspect power cord: Look for cuts, burns, or kinks in the Liebherr power cord. Replace if damaged.
- Check mains filter: Access the mains filter module where the cord enters the machine. Inspect for burning or swelling. Replace if faulty.
- Control board power: If the mains filter is good, the internal power supply on the main PCB may have failed. Board replacement is usually required and should be done by a technician.
