Possible Causes
Recent power outage, Loose connections in spa disconnect box, Undersized wiring to spa, GFCI breaker tripping intermittently
How to Fix / Troubleshooting
Safety first: Turn off power at the main spa disconnect before inspecting electrical connections. Only qualified persons should open electrical panels.
- Confirm stable power: Verify that the GFCI breaker feeding the Aquaterra Spa is not tripping and that household power is stable.
- Inspect spa disconnect: With power OFF, check for loose lugs or signs of overheating in the spa disconnect box. Tighten connections if you are qualified; otherwise, call an electrician.
- Check wire size: Ensure the wire gauge and breaker size match Aquaterra Spas installation requirements (refer to installation manual).
- Monitor for recurrence: If PF appears only after known outages, it is informational. If frequent without outages, have an electrician test line voltage under load.
Persistent PF errors can damage the control board. Professional electrical evaluation is recommended.
