How to Fix / Troubleshooting

Safety warning: Inverter-based microwaves use high-frequency high-voltage circuits that are extremely dangerous. Do not attempt internal repairs without proper training.

User-level steps:

  • Unplug the microwave for 10 minutes to reset the inverter protection.
  • Plug back in and test with a small cup of water on low power. If E15 reappears immediately, discontinue use.

Professional repair (for reference):

  • Check magnetron for shorts and proper operation.
  • Test inverter module according to Candy service procedures.
  • Replace inverter and/or magnetron as required.

Recommendation: Contact an authorized Candy service center. Do not continue to operate the microwave with E15 present.
