How to Fix / Troubleshooting
Safety first: Unplug the spa before tightening clamps or inspecting hoses.
- Run brief test:
- Fill the spa, then run the pump while observing all external hoses and the base of the control unit.
- Tighten pressure side fittings:
- Focus on the outlet from the pump and heater where pressure is highest.
- Tighten clamps and collars as needed.
- Inspect heater housing:
- Look for fine cracks or drips from the heater tube assembly when running.
- Replace if any leak is found.
- Check internal hoses (if accessible):
- Remove base cover and inspect for leaks only present when pump is on.
