Possible Causes

Blown internal fuse on mains input, Faulty Severin power cord, Failed main control PCB power supply, Loose mains terminal connections

How to Fix / Troubleshooting

Safety first: Ensure the appliance is unplugged before opening. Mains circuits can be lethal.

  • Check outlet and cord: Test the wall outlet with another device. Inspect the Severin power cord for cuts or burn marks. Replace the cord if damaged.
  • Inspect internal fuse: Open the housing and locate the small glass or ceramic fuse near the mains input. Remove and test with a multimeter for continuity. If blown, replace with the same type and rating after checking for shorts.
  • Check mains connections: Verify that all spade connectors from the mains inlet to the PCB are tight and not oxidized.
  • Examine power supply section: On the main PCB, look for burnt components or bulging capacitors in the SMPS area. If present, replace the main control PCB.

Warning: If the new fuse blows immediately, there is likely a shorted component (e.g., bridge rectifier, MOV, or primary switch). Do not keep replacing fuses; seek professional repair.
