Are you tired of jumping into your hot tub only to find the water is not warm enough? It can be frustrating to have spa heater problems.
If you’re questioning why is my hot tub not heating up? We’ve got you covered. Keep reading to learn more about the common causes of this issue and how you can fix it.
Reasons For Your Hot Tub Not Heating
Here are some reasons why your hot tub water is not heating up
1. Not Enough Power Supply
Check that the hot tub is securely plugged into a power source and that the circuit breaker has not tripped. Ensure that the power outlet can handle the electrical requirements of the hot tub.
2. Faulty Hot Tub Heater Element
One of the most common problems hot tub owners face is when the hot tub isn’t heating up properly.
This could be due to a malfunctioning heating element, which can be a real pain. If you’re seeing an error code on your spa pack or noticing a flow error, it’s time to investigate further.
3. Low Water Level
If the water level in the hot tub is too low, the heating element may not be able to function properly. Check and adjust the water level as needed to ensure proper heating.
4. Dirty Spa Cartridge
Another issue could be a dirty spa cartridge causing the hot tub or spa to stop heating up even if the hot tub gets hot.
If this doesn’t fix your hot tub, the water won’t be able to get hot enough.
A clogged filter can restrict water flow and prevent proper heating of the hot tub. Consider replacing the spa filter if the spa isn’t heating properly.
5. Thermostat Issues
The thermostat in the hot tub may be faulty or incorrectly set, causing the water temperature to not reach the desired level. Check and calibrate the thermostat to ensure proper heating.
6. Jet Flow Is Restricted
One possible problem could be that your jet flow through the heater is restricted. Before you panic, try reset button on your spa or hot tub.
If that doesn’t work, it could be a dirty spa filter or a malfunctioning hot tub heating element.
7. Airlock In The System
Air bubbles trapped in the hot tub’s plumbing system can prevent proper water circulation and heating. Bleed the system to remove any airlocks and improve heating efficiency.
8. Mechanical Issues
If none of the above solutions work, there may be a more serious mechanical issue with the hot tub’s heating system. Contact a professional hot tub technician to diagnose and repair the problem.
Troubleshooting Spa Heater Issues
So, if your hot tub isn’t warming up, here’s what you can try:
Use a Good Hot Tub Cover
To keep your hot tub in top shape, make sure you’ve got a good cover that fits properly and keeps the heat in.
If your cover feels heavy, that means it’s soaked up water and isn’t insulating well anymore. Swap it out if necessary to save energy and make your hot tub nice and toasty.
Thermostat Adjustment
If your hot tub is not as warm as it should be. It might need a thermostat adjustment.
It’s easy to do, but be sure to increase the temperature slowly to prioritize safety. Keep the temperature under 104°F (40°C) to maintain everyone’s health.
Add Insulation
To keep your hot tub warm in cold weather, add insulation around the cabinet and use a floating thermal blanket to trap heat and reduce evaporation.
Turn Off The Air Blower
The air blower in a hot tub can cause the temperature to drop by pushing cold air into the water.
To keep your hot tub warm, turn off the blower during colder weather, and turn it on during hot weather to introduce cooler air.
Consider the Weather
In cold weather, your hot tub takes longer to heat up. Plan ahead and start heating it early for a winter dip.
Circulation Pump
If your hot tub water is not heating up, the first thing you should check is the pump.
Sometimes it just needs a little TLC to get things back up and running. Give it a good once over and see if you can spot any issues. It might just be a simple fix.
Check The Water Flow
If spa parts like the pressure switch or high limit switch are malfunctioning, the hot tub may overheat or stop working. Check the flow of water through the heater to fix the problem.
Refill Your Hot Tub
If you’ve already checked those things and your spa water still isn’t reaching enough heat, it might be time to refill your hot tub with water. Make sure to turn your hot tub off and remove the spa cover before refilling.
You might also have hard water in your area, which can affect the overall temperature of your spa.
Replace The Heater
If your hot tub continues to have issues with heating even after you have refilled your tub, there may be a problem with your hot tub’s heater terminals.
In this case, you may need to replace the heater to get your hot tub to stop malfunctioning.
