How do you test an electric motor pump?
You should test the windings for a “short to ground” in the circuit and open or shorts in the windings. To test your motor for short to ground, you’ll need to set the multimeter to ohms and disconnect the motor from its power source. Then inspect each wire and look for infinite readings.
Can a low speed hot tub be on at the same time?
Remember: you can not check for a low speed problem while high speed is selected; both speeds cannot be on at the same time. If high speed will not engage either, and supply power is correct, you may have an internal wiring or circuit board problem. If not, trouble shoot based on the new symptom. NOTE: Ozonator works on low speed pump circuit.
Why does my hot tub not have power?
If the power is correct here, then the terminal or cord is damaged. If high and low speeds are operating simultaneously, then remove the pump cord and then examine the pump air switch for power. If both have power then there must be wiring trouble inside which has caused a short.
How to troubleshoot a hot tub and spa pump?
Turn off power to spa. Remove the pump and then remove the electrical housing cover on the top of the pump. Identify the faulty capacitor and replace. You will typically need a 8mm socket screwdriver and a very small flat headed screwdriver. With the new pump housing sealed and all electrics covered, turn the spa back on to dry, test the pump.
Why is my two speed pool pump not working?
We used it until May when we moved it to a different house. When we set it up again it appeared to be working fine until we tried to switch our two-speed pump from low to high. It made the normal “clunk” sound but there was no increase in the noise which I assume means no increase in RPM.
What should I do if my hot tub pump is not working?
If high and low speeds are operating simultaneously, then remove the pump cord and then examine the pump air switch for power. If both have power then there must be wiring trouble inside which has caused a short. If both speeds don’t have power then examine the pump cord for problems. If the cord is fine you have to change the motor.
Remember: you can not check for a low speed problem while high speed is selected; both speeds cannot be on at the same time. If high speed will not engage either, and supply power is correct, you may have an internal wiring or circuit board problem. If not, trouble shoot based on the new symptom.

What kind of circulation pump does a hot tub use?
Common spa/hot tub circulation pumps are made by Aqua-Flo, Grundfos, Laing and Waterway. Not all spas have a circulation pump however. Many spas use a 2-speed therapy pump, with low speed used for constant circulation, and high speed used for turning the jets on high.
When to turn on the power in a hot tub?
The most important first step is to never turn on the power when your hot tub is empty. If the pumps engage severe damage can happen instantly, damaging your pump beyond repair. Other tips for pump preservation include:
