Reset the breaker your hot tub is tapping into. If your power up is still not working, please give us a call.
The most likely scenario is pump 1 hi and low are reversed causing filtering on high instead of low. This will generate more heat.
The temperature reads closer to the heating element than the actual tub, the water flowing out of the jets.
In some cases, mechanical elements are enclosed in a waterproof “dock box” above ground. When the sun warms the dock box, you may get false temperature readings.
Please call and we can diagnose this further.
Check your relays. Your wiring could be wrongly installed. If you have trouble, please call us and we’ll be happy to walk you through the troubleshooting process.
Make sure to give the unit plenty of time to cycle. You could also test your grounding wires and make sure they are tight at the motors and casing.
