Spa Does Not Heat
Check the heating mode. Modes include standard, economy and sleep. During standard operation, the spa maintains the heat setting. The economy mode heats only during filtration. Sleep mode heats only during filtration, too, although it gets within 20 degrees of the preset temperature.
Measure the water in the tub to make sure it is at the recommended level.
Review the electrical system. Turn off the power or reset the breaker to see if this corrects the issue.
Open the gate valves all the way.
Spa Is Warm, Not Hot
Turn the heat up on the control panel.
Review filtration. Increase filtration time to increase water temperature.
Review the electrical system to ensure it is working correctly.
Replace or clean the filter if it is extremely dirty.
Open the gates valves all the way. Reposition the spa cover when not using the hot tub.
- If the water temperature is too hot, decrease the filtration time, as this should help the spa stay at the desired temperature.
- If you determine the heater is bad, contact the manufacturer or dealer for repair options.
