Why is my spa so hot?
A simple cause of hot tub overheating is the hot tub’s temperature may be set too high. Try setting your hot tub temperature to 98°F and see if this helps. This heat transfers into the tub water, increasing the temperature. So, if the hot tub is set to filter too many hours per day, it can cause overheating.

Is it possible for a spa heater to become unusable?
It is rare for a spa heater to become unusable, but it can happen from time to time. Remove the old one and install a replacement. If this still doesn’t solve the problem, you may have a wiring issue between the switch and the heater.
Why is my hot tub heater not working?
Check the switches for the hot tub heater and the motor or pump. The heater can not function properly unless the pump is running and water is circulating in the spa. Keep in mind that most supposed faults turn out to be some simple problem such as a switch that is caught partway between on and off settings.
Why is my spa skimmer saying Er 3?
Cause: Airlock in pipe work, low water level, dirty filter cartridges and faulty circulation pump. Take a garden hose and put it in the primary filter hole (if looking over the top of the filter box, it is the one on the left and has PZ marked on the skimmer lid)
How can I tell if my spa heater is on or off?
Make sure that the heater/filter cycle is on, and the thermostat is turned all the way up doing this test. Using the multi-meter or the amp-meter with the selector on voltage AC, take one lead from the meter and place it on one of the heater element post. Then take the other lead and place it on the other post.
How can I troubleshoot my hot tub heater?
Troubleshooting steps: Check filter for debris. Check the heating element. If your hot tub is heated with gas, check the pilot light and if it’s gone out, follow the manufacturer’s steps to relight it. The thermostat may need to be recalibrated if the water is getting too hot or staying too cold.
Why is the heating element on my spa not working?
If for any reason one of these components fail then the required voltage to the coil will be jeopardized and the contactor will not close in order to send power to the heating element. As mentioned above, it is usually one of these components that will cause a spa not to heat.
How can I tell if my hot tub element is bad?
If your breaker is not tripping but your hot tub still isn’t heating, testing voltage to the heater using a multi-meter will help determine the cause. With the spa on, test both of the leads on the element at the same time.
