- Check to see whether the GFCI is operating according to the manufacturer's instructions. If that appears to be properly set up, check to see if the impeller is plugged. You may need to disassemble and reassemble the impeller. If these do-it-yourself steps fail to clear up a pump problem, consult a dealer/installer or service representative.
- Check for blocked fittings, which cause poor flow and weak jet action. Test the jets at different speeds and physically inspect each jet. It's best to check while in the spa.
- If the pump has lost its prime, the main culprit is usually excessive air in the system. Make sure the water level is at least 2 inches above the top of the jets while the system is not operating. Check the suction piping for leaks, and check to make sure there is no vortex (whirlpool) at the suction.
- You must have adequate breaker capacity. A Jacuzzi spa will not work on 110 wiring and typically needs to have professional wiring and installation done before the Jacuzzi is turned on for the first time. Make sure that no other appliances are using the same circuit, and test the GFCI breaker according to GFCI manufacturer's instructions. This issue can also be caused by lightning damage to an outside circuit breaker. If you have recently had an electrical storm, suspect this issue and call a dealer for additional advice.
- At various points in ownership, you will experience technical difficulties that are easy to troubleshoot from home. This can save you a costly service call. Some of the most common Jacuzzi spa issues involve the pump, jets, circuit breaker and/or loss of prime. Typically, a little investigation will ferret out the source of your troubles, and most are easy to fix on your own.
