How to Fix / Troubleshooting
Safety: Only qualified persons should open the main electrical panel. Always turn off power before tightening connections.
- Step 1 – Confirm supply: Check that the GFCI breaker feeding the Vita Spa is fully ON and not tripped.
- Step 2 – Inspect spa connections: With power off, open the equipment bay and verify that L1, L2, and neutral (if used) are securely tightened at the control pack terminals.
- Step 3 – Measure voltage: Using a multimeter, confirm correct voltage (typically 240V between L1 and L2) at the spa pack. Low or fluctuating voltage can cause PF errors.
- Step 4 – Electrical service: If voltage is unstable or low, contact a licensed electrician to correct the supply issue.
