Why is Your Hot Tub Not Heating?

After long days at work, you know that you’ll be finishing your day by relaxing and unwinding in your hot tub. Have you ever found that your hot tub is not hot ─ even cold! If this happens, don’t worry, you’re not alone. One of the most common problems or complaints for a hot tub is that its heating might not work properly. Today, we’re discussing some tips on how to diagnose the roots of cause for hot tub heating problems as well as some simple fixes for these types of problems.
The first thing you should do is to test and eliminate all the potential problems that could be easily fixed. The most common problems that are easily fixable include flow issues. Flow issues occur when your hot tub does not have the minimum water level or when a blocked filter prevents water from flowing. Both problems are easily fixable. For the former, you could easily add more water while for the latter, you just have to clean your filter (and your pipes if needed). Another common problem is when your hot tub cover needs to be replaced as it fails to retain the heat inside of the tub. Loose wires and tripped electrical switch might also occur, similarly, both are easily fixable when detected. Last but not least, you also need to ensure that your hot tub is set to the right mode and that the hi-limit is properly set to the right temperature.
Complicated issues that might not be easily fixable by yourself usually involves problems with the heating unit or wiring. Your heating unit might lose its heating capability due to many reasons, including scale buildup, short circuits, or broken parts. To determine that the roots of cause is the failure of the heating unit, you will need to test its voltage or amperage using a multi-level and amp meter. The normal reading for a hot tub generally ranges from 9-12 Ohms. An abnormally high reading could indicate limited conductivity or open circuit while extremely low reading could indicate short circuit. If you acquire abnormal readings, it is advisable that you call a professional for further inspections. If you still fail to detect any of the aforementioned errors, then it is likely that the issue might occur due to the control board. In this case, you might want to ask a professional to check the power source to your hot tub.
