Hot Tub Not Hot? It Could Be A Pressure Or Electrical Problem

Owning a hot tub comes with some additional responsibilities. You have to maintain the appropriate temperature, keep the water pH balanced and do all of the necessary maintenance work. On top of the daily responsibilities comes learning how to troubleshoot some of the problems that can occur so you can try to make repairs quickly and with little expense. Below, you will find a few electrical and pressure troubleshooting techniques that can help you pinpoint some of the heating issues that may arise.

Pressure Problems

The water in your hot tub must be pushed through the heating system properly to maintain an adequate temperature. If the water pressure is not right, the water will either become too hot from being pushed through the system too slowly or too cool because it is moving too quickly through the heating system.

Look for Obstructions - Inspect the strainer basket, filter cartridge, suction outlets, pipes and pump impellers. Start with the strainer basket and filter cartridge. Chances are, if you have a clog somewhere, there will be a lot of built-up residue in both of these. Clean them out and replace them and test the system. If this fixes your problem, awesome!

Check the Pressure Switch – The pressure switch prevents water from becoming too hot. As water flows through the heating system, it must do so at a set level of pressure. If the water is flowing through the system too slowly, the switch deactivates the heating system, and the water will not heat as it flows through the system.

Electrical Issues

Your hot tub requires proper electrical connections to work efficiently. If one element of the electrical system is not working properly, the water will not maintain the perfect temperature.

Check the GFCI Outlet – If your hot tub is not getting any power, it could be caused by a tripped GFCI outlet or breaker. Reset the breaker and the GFCI outlet. If power is restored, great, but if this continues to be a problem, contact your electrician or hot tub repair technician to have the electrical system inspected.

Test the Terminals – Use a multi-meter electrical tester to test the heater terminals. Increase the setting on the thermostat and turn the pump on high. Touch the meter probes to the terminals. If the meter reading is less than 220 volts, your hot tub is not getting enough power to operate the way it should.

When you get in your hot tub, the water should always be the perfect temperature. This is not only for your comfort but also to maintain a bacteria-free hot tub for you to enjoy. If you have completed the above tests and still have not found the problem, call for professional service.
