Trying to figure out how to troubleshoot your hot tub can be frustrating. If you’re unfamiliar with your system, be sure to consult a qualified technician or your manufacturer’s manual. You may find that some common hot tub problems have simple fixes. However, many more complicated issues may require a full-service technician.
In any case, you should do your homework before you tackle any repair project. Some repairs, such as installing a new pump or circulation system, will be better left to a pro. Likewise, you should be careful about trying to repair your own hot tub, as the water can be dangerous. Using plungers and tools that don’t belong in a pool can void your warranty and can end up costing you a lot of money.
Aside from common maintenance practices, like checking the water level or balancing the pH and calcium levels, there are a number of other steps you should take. For instance, you should always inspect the filters for signs of dirt, and clean them regularly. Similarly, you should regularly run the water for at least 15 minutes. This will help you to get the most out of your system and minimize the chance of error codes or other complications down the road.
You should also check the control panel for an indication of an issue. The panel can display a number of different codes, from an LF or FLO message to a partially blank display. To troubleshoot your hot tub control panel, you may need to disconnect the circuit board and plug in a working one.
If your control panel still won’t do what you want it to, you might need to replace your faulty circuit board or your heating element. Even if you can’t take the plunge on this, you can usually test for the culprit by plugging in your hose and checking for a corresponding flow message.
On the other hand, if your tub isn’t getting any power at all, you might have an electrical problem. While this is a relatively common issue, it is best to wait until you can get a professional to assess the situation.
While there is no hard and fast rule of thumb, a low or weak water flow is a major bummer. There are a few tricks to solve this problem, though. One of them involves removing and replacing the insulation around your heating element.
Another good idea is to use a multimeter to check the voltage and current of your hot tub’s various components. This is especially useful if you aren’t very familiar with electronics. With a little luck, you might be able to identify the culprit.
If the above solutions don’t work, you may need to call a plumber or electrician. However, you should avoid attempting any of these tasks if you are unsure of your abilities.
If all else fails, you can have your local hot tub dealer or spa shop do the legwork for you. They may be able to tell you what the problem is and what you need to do. Or they may be able to send a specialist to your home to fix the issue.
