Introduction:
When you’re planning a relaxing soak in your hot tub, it can be a huge bummer if you realize it’s not producing any heat. But don’t panic – there are a few potential causes and easy fixes you can try. In this article, we’ll show you exactly what to do if your hot tub stopped heating as well as tips to prevent it from happening again.
Main Headlines:
1. Check Hot Tub Temperature Controls
The first and most common cause of a hot tub not heating is simply a malfunctioning temperature setting. If the tub is running, but not heating up, check the temperature settings. The easy fix is to make sure the temperature is set to at least 104°F. It may be that the temperature has been knocked off or bumped, causing it to malfunction.
2. Scrub the Heating Element
If the temperature settings appear to be working correctly, the next step is to inspect the heating element for any foreign debris such as hair, sand, or objects that might be restricting water flow. Make sure to scrub it thoroughly to ensure that the heating element is properly exposed to water.
3. Check the Heating Element
If scrubbing the element doesn’t resolve the issue, then it’s time to check the element itself. Test the heating element using a voltmeter while it is securely connected to your hot tub. It should register around 10 megohms of resistance. If it falls below this, then the element needs to be replaced.
4. Test the Flow Meter
If the heating element is functioning properly, another potential cause could be a malfunctioning flow meter. To check for this, first shut off the power to your hot tub and disconnect the flow meter. Now attempt to run water through the heating element – if it flows correctly, then the problem was likely a faulty flow meter.
5. Test the Pressure Switch
The pressure switch is a safety measure designed to ensure that there is enough water pressure in the system. Disconnect it and run some water through it. If the switch is functioning correctly, then you should hear a click when water runs through it. If the pressure switch isn’t clicking, then it needs to be replaced.
6. Check the Hi/Lo Switch
The hi/lo switch is generally located next to the jet pumps and filter. It should be set to the “Hi” or maximum setting to ensure proper operation of the heater. If it’s stuck on “Lo” or in the wrong position, the hot tub won’t heat up adequately.
7. Check the Water Temperature
If the temperature settings and all other components are fine, but your hot tub still isn’t heating up, it could be a problem with the temperature of the water itself. Ensure that the temperature of the water is no less than 80°F. Any colder and the water will not be able to hold a heat level – this can be remedied by topping up your hot tub with heated water.
8. Check the Water Level
If the temperature of the water appears to be fine, then the next step is to check the water level. If the water level is too low, the heater will shut down as a safety precaution. Top up the water level until it covers the skimmer and then try heating up the tub once more.
9. Have a Technician Inspect the System
If you’ve checked all the other components, but still can’t figure out why your hot tub isn’t producing any heat, then you’ll need to have a technician look at it. They’ll be able to determine the problem quickly and have your hot tub up and running in no time.
10. Hot Tub Maintenance Tips
To ensure that your hot tub is always running at its best, here are a few maintenance tips you should always keep in mind:
- Check for foreign objects regularly to prevent any kind of clogging or restriction to water flow.
- Balance the water chemistry of your hot tub at least once a month.
- Clean or replace the filter regularly to prevent blockages in the piping.
- Have a technician inspect your hot tub annually to ensure that all components are running smoothly and safely.
People Also Ask:
- How do I reset my hot tub? Reset your hot tub by pressing and holding the power button for 15 seconds and then restart it.
- What temperature should my hot tub be set on? Your hot tub should be set to 104°F and can be adjusted up or down.
- Can a bad filter affect the hot tub? Yes, a bad filter can cause a lot of problems with your hot tub, including not heating up.
- What causes a hot tub to freeze or overheat? Low water levels and incorrect temperature settings can cause a hot tub to freeze or overheat.
- How do I know when to clean my hot tub? Generally you should clean your hot tub every week if you use it frequently, or every two weeks if you use it less often.
Conclusion:
If your hot tub stopped heating, you don’t need to panic. It’s likely one of the components of your hot tub system needs to be checked or replaced. Fortunately, there are many signs to look out for and a few easy solutions. Make sure to check the temperature controls, heating elements, flow meters, and pressure switch to resolve the issue. Don’t forget to keep up with regular maintenance of your hot tub as well. With these tips, you’ll be soaking in a hot tub in no time!
