How to Fix / Troubleshooting
Safety: Electrical troubleshooting should be done with caution. If unsure, contact an electrician.
- Check GFCI breaker: Ensure the spa breaker is in the ON position. If tripped, reset once. If it trips again immediately, there is a fault that must be diagnosed.
- Verify disconnect: If your spa has a local disconnect box, confirm it is ON.
- Inspect control pack fuses: With power OFF, open the control pack cover and check for blown fuses. Replace only with identical type and rating.
- Check main lugs: Confirm that the main power wires are securely attached to the control pack terminals.
