Possible Causes
Shorted Elecro heating element, Water ingress into electrical compartment, Damaged internal wiring touching chassis, Incorrectly wired supply (neutral/earth fault)
How to Fix / Troubleshooting
Safety first: Do not repeatedly reset a tripping breaker. Isolate power and investigate.
- Visual inspection: Open the heater and look for obvious water ingress, corrosion, or burnt wiring.
- Dry the unit: If moisture is present, dry thoroughly and identify the source of the leak (glands, seals, pipe joints).
- Element insulation test: Have a technician perform an insulation resistance test on each element to earth. Replace any element with low insulation resistance.
- Check wiring routing: Ensure no conductor is pinched under covers or touching sharp metal edges.
If wiring and elements test good, have an electrician verify correct supply wiring and RCD operation.
