How to tell if a hot tub heater is working?

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 to troubleshoot a circulation pump in a hot tub?

Here’s how to troubleshoot a circulation pump on a spa or hot tub, to determine if the circ pump needs repair or replacement.

Circulation pumps used in spas and hot tubs, also called Circ Pumps or Hush Pumps, are low-flow pumps that constantly circulate the water (24/7) very slowly, to continuously filter, heat and chemically treat the water. Common spa/hot tub circulation pumps are made by Aqua-Flo, Grundfos, Laing and Waterway.

Why does my hot tub have extra low flow?

Secondary causes of extra low flow on a low flow hot tub circulation pump include the items mentioned above; either there is air in the line, or something is blocking flow before the pump on the suction side, or after the pump on the pressure side.

What to do if your hot tub circulation pump is not working?
