Why Is The Hot Tub Not Heating?

A hot tub not heating is fairly easy to diagnose.

Hot Tub Not Heating? There May Be Several Factors At Fault

When Florida's cool weather hits, there's nothing more invigorating than slipping into the toasty waters of a steamy hot tub. However, imagine your surprise when the water ends up being ice cold. So, why suddenly is the hot tub not heating up?

A hot tub during the cold temperatures can be exhilarating. Even though the winter is moderately warm in the Sarasota, Florida area, having a cold hot tub can still be annoying. The good news is that it is often a pretty simple problem to fix.

Before trying to diagnose the issue, it is important to remember make sure the power to the hot tub is turned off to help avoid the risk of electric shock. Be sure to turn the hot tub off, shut off the breaker and check that the hot tub is disconnected from all power sources. In fact, your best bet is to leave the work to an experienced professional pool and spa repair service.

Dirty Filters And Flow Switches Can Contribute To The Hot Tub Not Heating

Most modern hot tubs have computerized equipment and monitors to ensure proper functionality. One piece of that equipment is called a flow switch which tells the hot tub when to turn on and off. When there isn't enough water pressure flowing past this switch or if the water pressure is too low, the hot tub will turn off. This functionality helps to increase the longevity of the heater by reducing the amount of time it runs without actually heating any water.

If your hot tub is not heating, it very well could be because the water pressure is low and your flow switch keeps shutting off the power. The water pressure may be low due to a number of reasons including:

  • The flow switch may be malfunctioning

  • Clogged filters

  • Water level is too low

If the filter is dirty or clogged a simple rinse and cleaning should easily fix the problem. However, if the flow switch is broken, it may be best to leave that complicated repair up to a professional like Super Shark Pools, since their team has experience working with complicated computerized pool equipment.

The Hot Tub Not Heating Can Be Caused By A Broken Thermostat

As mentioned before, modern hot tubs contain several computerized components and one of those components is the thermostat, which is typically attached to the hot tub's mother board. Like many electronic components, the thermostat can become faulty with age or may even be improperly installed. A simple and inexpensive replacement of these parts can get your heating element working again.

Broken Heating Elements

Even though you work hard to make sure your hot tub's water chemicals are properly balanced, the water can still corrode components over time, including the heating element. Due to its smaller volume, a hot tub is especially sensitive to changes in acidity. Even a minor change can cause unexpected corrosion. If your heating element has malfunctioned, it is recommended that you call Super Shark Pools to replace the unit. We can also double check the water chemistry to ensure the proper pH levels are in place.

Is Your Hot Tub Turned On?

While that may sound sarcastic, it really is not. Many modern hot tubs have a safety feature known as a high limit switch that prevents the water from getting too hot and will shut it off if the water temperature reaches 110 to 120 degrees Fahrenheit depending on the model of your hot tub.

If your high limit switch keeps getting tripped, the switch itself may be malfunctioning, there might be an abundance of calcium built up or another glitch. Again, because this is another computerized component, it is recommended that our professional pool repair team at Super Shark Pools handle the replacement.
