Possible Causes
Heating element insulation breakdown, Moisture inside heater casing, Damaged wiring touching chassis, Faulty RCD/ELCB interaction
How to Fix / Troubleshooting
Safety: This is a potential electric shock hazard. Turn off power at the main breaker and do not operate the heater until the fault is resolved.
- 1. Inspect for moisture: Remove the cover and look for water traces, condensation, or leaks around connections and the heat exchanger. Dry the area and fix any leaks before proceeding.
- 2. Insulation test: With all power disconnected, perform an insulation resistance test (megger) between live terminals and earth on the heating elements and wiring. Low resistance indicates leakage.
- 3. Replace faulty element: If an element shows low insulation resistance to earth, replace the heating element assembly.
- 4. Check wiring: Look for damaged insulation or wires touching the metal chassis. Repair or replace as needed.
- 5. RCD check: Ensure the RCD/ELCB rating and type match Kospel’s recommendations. If in doubt, consult an electrician.
