So, how do you know if your spa’s relay is faulty? Here are some signs to look out for:
The hot tub is not heating up

If your hot tub is turning off randomly, the relay may be losing connection, and this could be due to a faulty relay. A faulty relay can cause your hot tub to shut off while in use, which can be frustrating and unsafe.
- Clicking sound from the spa board
- Tripped breaker on your spa
If you experience any of these issues, it is essential to inspect your spa board and check the relay. You may need to replace it to restore your hot tub’s proper functioning. Ignoring these issues can lead to further damage and safety hazards.
