Possible Causes
How to Fix / Troubleshooting
Safety: Do not repeatedly reset the breaker. Unplug the appliance and leave it disconnected until the fault is identified.
- 1. Visual inspection: Remove rear and top panels. Look for burnt components, melted insulation, or signs of water leaks onto electrical parts.
- 2. Heater test: Disconnect the tub heater wires and measure resistance between each terminal and earth. Any low resistance indicates leakage; replace the heater.
- 3. Motor and wiring: Check the motor and its harness for water ingress or damaged insulation. Dry any moisture and repair wiring as needed.
- 4. Mains filter and cord: Inspect the mains filter and power cord for damage. Replace if cracked or burnt.
Warning: Earth leakage faults can be dangerous. If you are not experienced with insulation testing, seek professional service.
