Flo-Thru Heater Element

If your spa fails to heat the water properly, the heater element should always be checked.

Defective elements that have been damaged by poor water balance usually trips the GFCI when the heat comes on. Elements that have just stopped working just don’t heat.

Most heater elements go bad because of improper water chemistry. To help you improve your water chemistry, we recommend the book, Spaaaahhhhhh The Owner's Guide to Understanding Spas and Hot Tubs .

Regardless of the age of your spa pack, if the only thing broken is the heater element, the economical thing to do is to replace the heater element.

To determine whether a universal element will work in your controller, remove your existing element from the controller. If the element has two probes on it that drop into the control box and has the same shape as the one above, then it will work in your controller. If it does not look the same, it is not a universal element and will not work.
