4 Common Hot Tub Heater Issues and Fixes

4 Common Hot Tub Heater Issues and Fixes

A hot tub is desirable for its soothing hot temperatures and massaging jets. When the water’s temperature turns cold, it’s a clear sign that something is wrong in the system. Read about four common hot tub heater issues and fixes to get your hot tub running smoothly again.

Broken Pressure Switch

The pressure switch is a safety device that measures the water pressure. In scenarios of low water pressure, the device turns off the heater. This is because a hot tub’s heater will overheat when water isn’t properly flowing through the system. If the pressure switch is broken, you may need to contact a local repair company to assess the issue and repair the switch.

Clogged Pipes and Filters

As mentioned above, low water flow will impact the heater’s effectiveness. Two other potential causes of this issue are clogged pipes and filters. Calcium scale, dirt, and debris can build up within the pipes and jets. The filters typically fill up due to excess minerals and oils in the water.

Clearing a pipe is a more intensive process than fixing a blocked filter. If the pipes are clogged, remove the filter first. Then, add a hot tub line-flush product to clear any residue from the pipes. Place the jets on high, and allow the water to pump through the pipes until the obstructions are gone.

Fixing the filter is a much simpler task! If the pipes aren’t the problem, all you must do is take out the old filter and replace it with a new one.

Faulty Thermostat

Another common hot tub heater issue is with the thermostat. Older hot tubs may have a mechanical dial, while newer ones have a temperature sensor attached to a circuit board. Some of the causes of a failing thermostat are poor connections, improper installation, or a failing sensor.

If a faulty thermostat is the root of your hot tub’s problem, you’ll need to buy and install a new one. It’s an affordable fix that will have your hot tub functioning again quickly.

Malfunctioning Heating Element

Hot tub heating elements typically last for five to 10 years. Over time, the wires can fray or burn, which may cause a poor connection and cold water. In addition, there may also be a lack of power running to the heating element. In this case, you can test the voltage or power continuity. If you don’t feel comfortable, ask a professional to test these parts of the hot tub. They can gain an accurate reading and safely repair any issues.

Some of these issues have easy fixes. But when complications with your hot tub arise frequently, it may be one of the signs you need to upgrade to a new hot tub. Keep this in mind, so you can maintain a hot tub that’s safe and efficient for you and your loved ones.
