How to Fix / Troubleshooting

Safety first: Ensure your hands are dry and the outlet is safe. Disconnect from mains before opening the unit.

  • Check outlet: Test the wall outlet with another appliance to confirm it has power.
  • Inspect power cord: Examine the cord and plug for cuts, kinks, or burn marks. Replace if damaged.
  • Try another outlet: Plug the Thermomix directly into a different known-good outlet without extension cords.
  • Internal fuse check (advanced): With the unit unplugged and bottom cover removed, locate and test the internal fuse on the main PCB. Replace only with the exact same type and rating if blown.
  • Service requirement: If the fuse blows again or the unit remains dead, the power supply or main PCB is likely faulty and should be replaced by an authorized service center.
