My Hot Tub Heater Doesn't Work

Heat problems in your hot tub can require maintenance.

Heat problems are common in hot tubs. The element that heats the water is in constant use and has to normally compete with cooler outside temperatures. A few steps can help correct hot tub heating problems.

Facts

When you first detect heat problems in your hot tub, check the electrical connection to the unit. Faulty connections can result in insufficient power to the heater. Review the control panel to ensure the hot tub is in the proper mode for heating water.

Corrective Actions

Hot tubs have a variety of parts or equipment that will affect the water's temperature. Dirty filters, clogged water intakes, low water levels or partially closed plumbing valves can restrict water to the heating element. You will need to diagnose each of these parts to determine the problem with the hot tub.

Considerations

Major issues like pump, motor or heating element problems can occur during the lifetime of your hot tub. These issues may require you to contact the hot tub dealer. Failing to correct these issues right away can result in costly repairs for the unit.
