How to Fix / Troubleshooting

Critical safety warning: This involves mains voltage. Turn OFF the breaker and verify no voltage is present before opening the unit. If you are not trained in electrical work, call a professional.

Steps:

  • 1. Check supply voltage: With the breaker ON and cover in place, measure voltage at the service panel to ensure it matches the heater's rating. Then turn OFF the breaker before opening the heater.
  • 2. Inspect power terminals: Remove the cover and check the main power terminal block for loose screws or signs of overheating. Tighten to specified torque.
  • 3. Internal fuse: Locate any internal fuses on the PCB or power module. With power OFF, test continuity and replace with identical type and rating if open.
  • 4. Visual inspection of PCB: Look for bulging capacitors or burned components in the low-voltage power supply section.
  • 5. Test operation: Restore power and check if E14 clears.

Professional help: If the internal power supply is defective, the PCB must be replaced by a qualified technician.
