How to Troubleshoot Common Hot Tub Problems

Hot tub ownership can be a source of great relaxation and enjoyment. However, like any appliance, hot tubs can experience issues from time to time.

This guide will help you troubleshoot some common hot tub problems, so you can get back to soaking in peace.

  1. Problem: Hot Tub is Not Heating Properly

If your hot tub isn't reaching the desired temperature, check the thermostat first to ensure it's set correctly. If that's not the issue, inspect your hot tub's filters. Dirty or clogged filters can affect the heating efficiency. If your filters are clean and your thermostat is correctly set, the problem may lie with the heater element or the pump, and professional help may be needed.

  1. Problem: Hot Tub is Leaking

Leakage in a hot tub can occur from several places like the pump, the heater, or the plumbing. Check these components for signs of leakage. If it's a minor leak, a sealant might be able to fix it. However, significant leaks will likely require professional repair.

  1. Problem: Weak or No Jet Pressure

If the jets in your hot tub are weak or not working, the problem could be due to clogged filters, low water levels, or an issue with the pump. Clean or replace the filters if necessary, top up the water level, and if the problem persists, consult a professional.

  1. Problem: Cloudy or Foamy Water

Cloudy or foamy water can be caused by imbalances in your water chemistry, high calcium levels, or organic impurities. Test your water and adjust the chemical balance as necessary. If your water is still cloudy or foamy, a water clarifier or defoamer can help. Remember to regularly use a reliable scum remover like ScumRay to prevent build-up and keep your water clear.

  1. Problem: Error Codes on Control Panel

Hot tubs often have digital control panels that display error codes when there's an issue. Refer to your owner's manual or the manufacturer's website to understand what these codes mean and how to resolve the issues.


Troubleshooting common hot tub problems can help you keep your hot tub running smoothly. However, always consult with a professional if you're unsure or if the problem persists. Regular maintenance, including keeping your hot tub clean with a trusted scum remover like ScumRay, can prevent many issues and extend the lifespan of your hot tub.
