How to Fix / Troubleshooting
Safety first: Do not repeatedly reset a tripping breaker or RCD. Risk of electric shock or fire.
- Visual inspection:
- Unplug the spa and inspect the power cord for cuts, burns, or crushed sections.
- Check the control box for signs of water ingress.
- Dry any moisture:
- If water is present inside the control unit, dry thoroughly and allow 24 hours before retesting.
- Isolate components (advanced):
- A technician can disconnect the heater, pump, and blower one at a time from the PCB to identify which component causes the trip when reconnected.
- Replace faulty part:
- If the trip occurs only when a specific component is connected, replace that component (e.g., heater tube assembly, pump motor, or air blower).
