If you've just bought a hot tub, there are some things about caring for it that you should know. Continue reading to discover frequently asked questions that deal with maintaining, cleaning, troubleshooting, and operating your new hot tub. 

What Can You Try When Your Hot Tub Isn't Heating Up?

If your hot tub isn't heating up properly, there are a few things that may be causing the problem. If your tub has been running without heating up, it's likely that the thermostat has failed or gotten stuck in a position where it can't detect temperature changes. 

If your spa does not heat up at all or only heats up for short periods of time before shutting off again, then there could be an electrical issue with either the breaker or fuses in your home's electrical panel box.

What Are Common Causes of Hot Tubs Failing to Heat?

There are several possible explanations for why your hot tub isn't heating up properly. Some of the most common causes include:

  • Rusted or corroded heating element: If the heating element is heavily rusted or corroded, it's likely that it no longer works. 
  • Faulty wiring: The wiring running from the pump to the heater could be faulty and in need of repair or replacement. This can cause your hot tub to not heat up properly.
  • Leaking gas valve or gas line leak: A leaking gas valve or line can cause a variety of issues with your hot tub, including heating problems. A leaky gas line can also pose risks to people using the tub as well as those who service it.
  • Bad thermostat setting: If you've checked all of these other areas and still cannot figure out why your hot tub isn't heating up properly, then you may need to adjust your thermostat setting on your control panel manually until it reaches a comfortable temperature for use.

These are common reasons why hot tubs don't heat up.

How Can You Get Your Hot Tub To Heat Up?

If your hot tub isn't heating up, there are a few things you can do to get it back on track. First, check the filter and make sure there's no buildup of dirt or debris. If you have an electric hot tub, make sure that the circuit breaker hasn't tripped or that the breaker box is not damaged. If your hot tub has a gas heater, check to see if there are any gas leaks or problems with the pilot light system.

You might also try resetting the temperature control by turning off power to your hot tub and then flipping the breaker switch back on. This will reset all of your electronic components, which could help resolve any issues with heating.

What Are Some Water Pressure Problems with Hot Tubs?

If your hot tub is experiencing problems, it's important to determine what the issue is and how to fix it.

The most common issues are low water pressure problems. If you're having trouble getting your water jets to work properly or if you have a slow drain, it could be because of low water pressure. Here are some things to look out for:

  • The jets aren't working properly: When there isn't enough water pressure, the jets won't be able to create the bubbles needed for massage. Sometimes, the pump could have been turned off by accident, and you might want to check this before calling for repairs. 
  • The drain is slow or clogged: Low water pressure can cause drains to become clogged if they aren't working correctly. Make sure that all drains have been unclogged to deal with this problem.
  • The filter isn't working properly: If your filter isn't working correctly, then that could be another cause behind low water pressure in your hot tub. 

These are common hot tub issues that you might want to troubleshoot before calling for repairs.
