Common Causes for a Garden Spa Hot Tub Not Heating

When your garden spa hot tub is not heating properly, it can be frustrating and disappointing. To help you troubleshoot the issue and get your hot tub back to a relaxing temperature, let’s take a look at some common causes for this problem:

  1. Heating Element Malfunction: The heating element in your hot tub is responsible for raising the water temperature. If it becomes faulty or damaged, the tub may not heat up properly. This can happen due to aging, wear and tear, or electrical issues. When troubleshooting, check for any signs of damage to the heating element or consult a professional to diagnose and replace it if necessary.
  2. Thermostat Issues: The thermostat helps regulate the temperature of your spa hot tub. If it is not functioning correctly, it may not signal the heating element to turn on or off at the desired temperature. Make sure the thermostat is set correctly and consider testing it with an external temperature gauge to ensure its accuracy.
  3. Clogged Filters: A common cause of poor heating in hot tubs is clogged filters. Over time, debris and contaminants can accumulate in the filters, restricting water flow and affecting the heating process. Clean or replace the filters regularly to ensure proper water circulation and efficient heating.
  4. Low Water Level: Insufficient water in the hot tub can prevent proper heating. If the water level is too low, the heating element may not be fully submerged, leading to inadequate heating. Check the water level and add more, if necessary, to ensure it covers the heating element adequately.
  5. Electrical Issues: Electrical problems can also interfere with the heating function of your spa hot tub. Faulty wiring, tripped breakers, or blown fuses can disrupt the power supply to the heating element. If you suspect an electrical issue, it’s essential to consult a professional electrician to diagnose and resolve the problem safely.

Remember, troubleshooting and diagnosing hot tub heating issues can be complex. If you’re unsure or uncomfortable with performing these tasks yourself, it’s always best to seek the help of a professional spa technician. They have the knowledge and expertise to identify the problem and provide the appropriate solution.

To begin troubleshooting why your garden spa hot tub is not heating, the first step is to check the power supply. Here are some things you can do to ensure the power supply is not the issue:


  1. Verify that the hot tub is properly plugged in and receiving power.
  2. Inspect the circuit breaker or fuse box to see if a breaker has been tripped or a fuse has blown. If so, reset the breaker or replace the fuse.

Inspect the Thermostat

If the power supply is not the problem, the next step is to inspect the thermostat. Here’s what you need to do:

  1. Check the temperature setting on the thermostat. Make sure it is set to the desired temperature and not on “off” or “standby” mode.
  2. Verify that the thermostat’s display is working properly. If it’s not showing any signs of life, there may be an issue with the thermostat itself.
  3. Calibrate the thermostat if necessary. Sometimes, the thermostat may not be reading the temperature accurately, leading to heating problems. Consult the manufacturer’s instructions or contact a professional for guidance on how to calibrate the thermostat.

Test the Heating Element

If the power supply and thermostat are functioning correctly, it’s time to move on to testing the heating element. Follow these steps:

  1. Inspect the heating element for any signs of damage, such as broken or discolored coils. If you notice any damage, it may need to be replaced.
  2. Turn off the power to the hot tub before proceeding with any further testing.
  3. Use a multimeter to test the heating element for continuity. This will help determine whether the element is functioning properly or needs to be replaced. If you are unsure how to use a multimeter, refer to the manufacturer’s instructions or seek professional assistance.

Remember, troubleshooting and diagnosing hot tub heating issues can sometimes be complex. If you are unsure or uncomfortable with performing any of these steps, it’s best to seek the help of a professional. They have the expertise and experience to diagnose and fix the problem accurately.

Protect the Tub from Exposure to Extreme Temperatures

Extreme temperatures, whether too hot or too cold, can have a negative impact on your hot tub’s heating system. Follow these tips to protect your tub:

  • Insulation: Properly insulate your hot tub to prevent heat loss. Insulation can include a thermal cover, insulating panels, or a floating thermal blanket.
