So in this blog post, I’m going to show you how to fix dry heater in hot tub. So read on and learn how to keep your hot tub warm all winter!
Summary: You may need to troubleshoot the issue if your hot tub’s heater is not working properly. To fix a dry heater in a hot tub, start by checking the electrical connections, then inspect the pressure switch and check for calcium buildup. If needed, replace the circulation pump, thermal switch, and pressure switch as necessary. Finally, make sure to fill up your hot tub with enough water so that it reaches its optimal temperature range.
What Causes a Dry Heater in Hot Tub?
There are a few different things that can cause your heater to go dry. The most common reason is that the pump isn’t circulating the water. This can happen if the pump is turned off or there is a system blockage. Another common reason is that the filter isn’t clean. A dirty filter can cause the water to bypass the heater, which will cause it to go dry.
Additionally, if the temperature setting on the heater is too low, it can also cause the heater to go dry. The other less common reason is that the heating element itself is damaged. Lastly, if there is a problem with the wiring, it can also cause the heater to go dry.
Why Is It Important to Fix a Dry Heater in Hot Tub?
It’s important to fix a dry heater in your hot tub because if the heater is dry, it can’t heat the water. This means that your hot tub will be significantly cooler than it should be. Additionally, if the heater is dry, it can damage the heating element. This can be expensive to replace and shorten your heater’s lifespan.
Another reason why it’s important to fix a dry heater in your hot tub is that if the water isn’t being heated, the chemicals in the water can start to break down. This can cause the water to become acidic, which can be dangerous for you and your family. Finally, if the water isn’t being heated, it can start to grow bacteria. This can cause you to get sick and can also lead to the growth of algae.
A Complete Guide on How to Fix Dry Heater in Hot Tub
1. Check the Pump
The first thing you should do if you think your heater is dry is to check the pump. Ensure that the pump is turned on and there is no blockage in the system. If the pump is turned off, turn it on and see if that fixes the problem. If there is a blockage in the system, you’ll need to remove it before the heater works correctly.
2. Clean the Filter
If the pump is running and there are no blockages in the system, you should next clean the filter. A dirty filter can cause the heater to overheat and shut down. To clean the filter, first, remove it from the hot tub. Then, rinse it off with a hose and let it air dry. Once it’s dry, put it back in the hot tub and see if that fixes the problem. Try not to use your hot tub until the filter is completely dry. Avoid using chemicals to clean the filter, as they can damage it.
3. Check the Temperature Setting
If the tub is running and the filter is clean, you should next check the temperature setting on the heater. The ideal temperature for a hot tub is between 102 and 104 degrees Fahrenheit. If the temperature is set too low, the heater will dry out. To adjust the temperature, first, find the thermostat.
Then, turn it to the desired setting and wait for the heater to kick on. Once the heater is on, check the water temperature to make sure it’s at the desired setting. Try not to adjust the thermostat more than 1 degree at a time as it can cause the heater to overheat.
4. Replace the Heating Element
Heating elements typically last for about five years. If your heater is dry and the heating element is more than five years old, the element likely needs to be replaced. You can purchase a new element from the most pool and spa supply stores. First, replace the element, and turn off the power to the heater. Then, remove the access panel and locate the element.
Remove the wires from the element and unscrew them from the heater. Screw in the new element and reattach the wires. Replace the access panel and turn on the power to the heater. Allow the heater to run for a few hours to ensure the new element is working properly.
5. Check the Wiring
If the heating element is new and the heater is still dry, you should next check the wiring. Sometimes, the heating element will come loose from the wiring and will need to be reattached. Other times, the wiring itself may be faulty. To check the wiring, first, make sure that the power is off to the hot tub. Then, remove the access panel to the heater and visually inspect the wiring. If you see any loose wires, reattach them. If the wiring looks damaged, you will need to replace it.
6. Check the GFCI
The GFCI, or ground fault circuit interrupter, is a device that prevents electrical shocks. It’s usually located near the electrical panel or where the power cord enters the hot tub. If the GFCI trips, it will shut off the power to the hot tub. To reset the GFCI, press the “reset” button. If the GFCI trips again, there may be a problem with the electrical wiring. Avoid using the hot tub until a qualified electrician fixes the problem.
7. Drain the Hot Tub
If you’ve tried all of the above and the heater is still dry, the next thing you should do is drain the hot tub. Draining the tub will allow you to access the heater and make any necessary repairs. To drain the tub, start by shutting off the power to the tub. Next, remove the drain cap and attach a garden hose to the drain valve.
Turn on the water and allow the tub to drain completely. Once the tub is empty, remove the heater and inspect it for damage. If the heater is damaged, it will need to be replaced. If the heater is not damaged, you can reattach it and fill the tub with water.
8. Call a Professional
If you’ve tried all of the above and the heater is still dry, it’s time to call a professional. A qualified technician will be able to diagnose and fix the problem quickly. They may also be able to give you advice on how to prevent the problem from happening again in the future. Try to find a technician who is certified by the National Hot Tub Association. This will ensure that they have the knowledge and experience to repair your hot tub properly.
