Why won’t the hot tub heat?

If your hot tub is not heating up, there are several things you can check to try and resolve the issue. We know it’s frustrating when your hot tub isn’t working correctly. That is why we’ve put together this guide to help you troubleshoot the most common problems with heating.

We’ve outlined some of the most common causes of this problem and how to fix them. So don’t give up on that relaxing soak yet – read for some solutions.

Hot tub heater elements and their importance

The heating element is what heats the water in your hot tub. These are located in the heater and work by converting electrical energy into heat.

There are two types of heating elements:

●  Coil heating elements– These are made of a coil of resistive wire wrapped around a metal rod. When electricity is passed through the ring, it heats up and transfers heat to the water.

●  Cartridge heating elements– These are made of a resistive wire wrapped around a ceramic core. They work the same way as coil heating elements but can withstand higher temperatures.

If your hot tub heater isn’t working, the spa heater element is likely the problem. You will need to replace the spa heater element if it is defective.

The importance of these heating elements include:

●  They help to maintain the water temperature in your hot tub.

●  If the element is not working, the water will not be heated, and you will not be able to enjoy a warm soak or  make your hot tub hotter.

 Heater elements are not always the cause of heating issues in your hot tub, but they are the most common culprit. If your heating elements are not working, it is essential to replace them as soon as possible so that you can enjoy your hot tub again.

Top 6 Hot Tub Non-heat Problems

A hot tub without heat is no fun. Several things can go wrong with your hot tub heater. Here are the top 5 heater problems and how you can fix them, including:

Low flow (water flow)

If there is not enough water flowing over the heater coils, then the element will not be able to heat up properly. It could be due to a dirty spa filter, clogged jets, or a problem with the pump. You should check your filter and clean or replace it if necessary. You should also ensure that all the jets are pushing out water and that the pump works properly. If you have checked all of these things and there is still low flow, you may need to call a technician to check for other issues.

If the thermostat is not working

The thermostat controls the water temperature in your hot tub. If it is not working correctly, the water will not be heated to the correct temperature. You should check the thermostat to see if it is set to the right temperature. If it is, you may need to replace the thermostat.

The heating element is not working

Hot tub heater elements heat the water in your hot tub. If it is not working, then the water will not be heated. You should check the heating element to see if it is burned out. If it is, you will need to replace it.

Circuit breaker trips

The circuit breaker provides power to the hot tub heater. If it trips, the power will be cut off, and the heater will not work. You should check the circuit.

High Limit Switch or pressure switch

The high limit switch is a safety device that shuts off the power to the heater if the water temperature gets too high. If this happens, you will need to reset the switch.

Hot tub jet pump

The pump circulates the water in your hot tub. The water will not be heated if it is not working correctly. You should check the pump to see if it is clogged or burned out. If it is, you will need to replace it.

Hopefully, this guide has helped you troubleshoot the problem with your hot tub heater. Before checking the heater, remember to check things like the filter, jets, and pump.

Other causes of Heater Problems

GFCI Tripped

The GFCI (ground fault circuit interrupter) is a safety device that protects you from electrical shocks. It can trip if there is a problem with the electrical supply to the hot tub. You should check the GFCI and reset it if necessary.

Water leaks

Water leaks can also cause heater problems. If there is water leaking onto the hot tub equipment, it can cause the heater to trip. You should check for leaks and repair them if necessary.

Door interlock open

The door interlock is a safety device that prevents the hot tub from operating if the door is open. If the door is available, the heater will not work. You should close the door and reset the switch.

The spa cover needs replaced

The spa cover helps to keep the heat in the hot tub. If it is damaged, it will not be able to do this properly. You should check the spa cover and replace it if necessary.

Loose wires

Loose wires can also cause heater problems. You should check the wiring and tighten any loose connections.

Blown Fuse

A blown fuse can also cause heater problems. You should check the fuse and replace it if necessary.

If you have checked all of these things and your hot tub heater still isn’t working, you may need to call a technician for help. Hot tub heaters are complex equipment, and there may be other issues you are unaware of. A technician will be able to diagnose the problem and get your hot tub heater up and running again.
