Why is my hot tub heating slowly?
Low flow in your spa or hot tub is most commonly associated with a dirty spa filter. If your spa heater won’t heat, remove and clean the filter(s) rule out a pressure or flow rate problem. Low water level, a clogged pump impeller, closed valves, clogged pipes or blocked spa drain covers can also cause flow issues.
How do I check the heating element in my spa?
To test hot tub heating elements for integrity, use an ohm meter on its lowest setting. With the meter’s test leads, measure the resistance between the two element terminals. The acceptable resistance range for most heaters is between 9-12Ω (ohms), some may be as high as 20Ω.
How can I prolong the life of my spa element?
Prolong heater life by setting heating cycles by time of day rather than relying upon thermostatic demand. Switching a heater on and off many times per day puts more strain on the element. If your spa does not have a timer, don’t lose any sleep over it.
Why is the heating element on my spa not working?
If for any reason one of these components fail then the required voltage to the coil will be jeopardized and the contactor will not close in order to send power to the heating element. As mentioned above, it is usually one of these components that will cause a spa not to heat.
When to replace a hot tub heater element?
If the heater assembly is more than a few years old, it is best practice to replace the whole heater. Over time, corrosion and scale can deteriorate the heater assembly. Need help finding a replacement heater or heater element?
How can I tell if my hot tub element is bad?
If your breaker is not tripping but your hot tub still isn’t heating, testing voltage to the heater using a multi-meter will help determine the cause. With the spa on, test both of the leads on the element at the same time.
Why does my spa heater stop working after 8 years?
However, it the spa isn’t heating at all, and there are no tripped circuit breakers or error codes, it is possible that the heater element has already failed. In fact, many spa heater elements will stop working, especially after 8 years. There are different types of spa heaters but the most common are the electrical flow through spa heaters.
