What Would Cause A Hot Tub To Overheat?

There are a few reasons why a hot tub is overheating. Overheating of a hot tub can happen because the pump has been running for some time due to extended filtration cycles settings or faults within the control system.

One of the reasons might be the air temperature during the summer period as well. Also, another reason for overheating is sensor malfunction and electrical problems as well. Even if one is using the hot tub for some prolonged time it might cause overheating. And the simplest reason for the hot tub overheating is the wrong adjustment of the temperature (the temperature is too high).

One must be aware that this problem is normal and might occur anytime but most commonly it happens during the summer period when the air is hot and humid. It is perfectly natural for this problem to be happening and it is not related to the hot tub brand or age of the hot tub. It is a simple industry error that might happen anytime, everywhere, and to anyone.

There are some simple solutions to these problems like adjusting the filters, adjusting the filter cycle periods, and turning the air controls to the open period. If there is any serious problem then professional help should be required and manual instructions should be followed. 

In the end, these are some of the major reasons that cause the hot tub to overheat. The others, less reported are: dirty spa filter, closed or partly closed jets, airlock on the pump, the low water level in the hot tub, or the hot tub drain is covered.

How do I Stop my Hot Tub from Overheating?

There are some very simple tests on how to stop the overheating of the hot tub:

  1. Turn the temperature down.
  2. Add some cool water.
  3. Avoid running the filter if it is hot.
  4. Put some shade over the hot tub.

The first one is the simplest and the most reasonable way to stop the hot tub from overheating. It is a straightforward solution in just one step of adjusting the temperature according to the air temperature during the different seasons. 

Adding cool water is also a very simple way to stop the hot tub from overheating. If one sees that the water is too hot and about to boil even in some cases, a few gallons of the cold water might just help the case and save you time and energy. But a certain procedure must be followed when doing this and that is in following these steps: turning the hot tub down, draining some amount of water, and adding the fresh, cold water. Then, when turning the hot tub again, adjust the temperature to a lower degree than it was before. 

Next, rescheduling the filtration cycles to run during the coolest is the smartest way to save filters and assure that the hot tub runs normally.

It is very reasonable if one is using the hot tub during the summer to maybe use the shade over the hot tub to prevent the water heating when the hot tub is not on. The shade is a cheap way of assuring the normal temperature before the hot tub is used.
