Ideal Electrical Short or Earth Leakage

Water heater trips the electrical breaker or RCD when it starts.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Water ingress on PCB, Shorted pump windings, Damaged wiring insulation, Faulty fan motor

Safety: Do not repeatedly reset a tripping breaker; this indicates a fault.

Inspect for leaks: With power off, check inside the casing for any signs of water. Fix leaks before addressing electrical issues.
Check flex and plug (if fitted): Look for cuts or crushed sections in the supply cable.
Isolate appliance: Leave the heater switched off and contact a qualified electrician or service engineer to test insulation resistance and identify the faulty component.
