Jacuzzi hot tubs can run into problems that usually have to do with their water. You need to refill and treat the water periodically to maintain a shiny appearance and water health. Other common issues with Jacuzzi hot tubs relate to the mechanics, particularly the jets supplied by pumps. You can identify and rectify these and other problems with some troubleshooting.
Adjust the hot tub jets until you get a stream you like. Turning counterclockwise should increase the flow. If you are unable to get the correct stream, purge air from the system. Air in the system can cause a weak stream. Turn off the hot tub, and then turn the massage selector's cap counterclockwise. Listen for escaping air. You should hear it hiss. When the air stops escaping, the jet should be purged. Try it again.
Test the water quality for the correct balance if the water is dull. It should be shiny. The pH should be between 7.2 and 7.8. Test the water with a kit. Add sodium carbonate to increase the pH, and sodium bisulphate to lower it. Follow the directions on the packages for quantities based on the size of your hot tub.
Raise the water level in the Jacuzzi hot tub at least 2 inches over the filters if the jet pump surges on high speed. Simply fill the hot tub with a garden hose---the water can evaporate.
Exchange the remote control's batteries for fresh ones if you can't operate the jets or the music system (if you have one) with your remote.
