Jacuzzis are a brand name of whirlpool spas and hot tubs. The moniker has become commonly used when referring to any brand of whirlpools, hot tubs or any other types of baths with water jets. These soothing tubs relax and massage sore, tired muscles and can even be romantic. However, if your Jacuzzi is not working, it will not do any of that. Try some troubleshooting on your own before you call an expensive repair tech.
Try to turn on the Jacuzzi. If it does not power on, check the power source and circuit breaker. Reset the GFCI button. If it still does not turn on, replace the fuse.
Test the water temperature. If the water is staying too hot, turn the thermostat counterclockwise. If this causes it to cool down, replace the thermostat. If it does not cool down, replace the heater contact.
