Possible Causes

How to Fix / Troubleshooting

Safety first: Repeated tripping indicates a potentially dangerous fault. Do not bypass or replace a GFCI/RCD with a non-protected breaker.

  • 1. Identify when it trips:
    • Note whether the trip occurs immediately at power-up, when a specific pump starts, or when the heater engages.
  • 2. Inspect for moisture:
    • Open the equipment bay and look for leaks or standing water around pumps, blower, and heater.
    • Dry any moisture and repair leaks before re-energizing.
  • 3. Isolate components (technician):
    • A professional can disconnect pumps, blower, and heater one at a time to identify the faulty component.
  • 4. Check wiring and breaker size:
    • Verify the spa is wired according to Wellis specifications and local code.
  • 5. Replace faulty component:
    • Replace any pump, blower, or heater that tests with a ground fault.
