Possible Causes

Blown internal fuse, Faulty power cord, Failed main PCB power supply section, Tripped household breaker or faulty outlet

How to Fix / Troubleshooting

Safety: Ensure the outlet is not live before touching bare wires. Unplug the unit before opening any covers.

Steps:

  • 1. Check outlet: Plug another appliance or a lamp into the same outlet to confirm it has power. Reset the circuit breaker or replace the wall outlet if necessary.
  • 2. Inspect power cord: Look for cuts, kinks, or burn marks. If damaged, replace the La Sommeliere power cord.
  • 3. Access main PCB: Remove the rear or top cover to reach the control board. Look for an onboard fuse near the AC input.
  • 4. Test fuse: Remove and test the fuse with a multimeter. Replace only with the same type and rating if blown. If it blows again immediately, there is a short that requires professional diagnosis.
  • 5. Inspect PCB: Look for burnt components or cracked solder joints in the power supply section. If present, replace the La Sommeliere main control board.

Warning: Do not bypass fuses or operate the unit with exposed live parts.
