Thread: Low speed motor malfunction
07-03-2009, 06:27 PM #1
I have a Marquis spa with a 2 speed motor(220V). The motor does not go on into low speed from start-up. If I press the start buttom twice I can get it to jump into high speed. From High speed the pump can go into low speed with no troble and back to high again. Is the motor inability to go to low speed from start up a motor or control circuit problem. Any suggestion on how to determine which if both are possibilities.

When the spa pump is in high speed are you saying by pushing the button on the spa top side panel you can get it to go from high to low, but if you just push the spa top side panel button once it will not go into low speed? If you just push the jets button for low speed does the indicator come on the top side panel?

When in high speed if I press the button once it usually goes into low. Some times it turns the pump off. When that happens I usually cannot get the motor to restart without pulling the breaker(turning off all power to the tub). When I do this and repower the tub I can get it to jump into high again when it is trying to start up in low by pressing the button when I here the circuits tryinbg to start. What I was trying to say is when the hot tube cycles to low after ten minutes of use at high I can press the buttom once and it goes back into high. When finished with tube it goes from high to low and stays in low for the clean up cycle. After the clean up cycle the motor will not go into low for routine nightly cleaning and temperature maintenance,
Hope this clarifys my problem

Thank you, I was trying to determine if the top side panel was the issue. It sounds more like the circuit board since it will not go into it's filter cycles. Can you hear the relays clicking when you push the button for low speed?

Yes some of the relays are clicking. When the tube trys to enter routine cleaning or temperature maintenance I also hear clicking.

If you are hearing the relays clicking when you press the top side panel I am inclined to think it is not the spa top side panel causing the problem. I think this problem may be the spa circuit board. If you are comfortable using a voltage meter, you can push the button on the top side once to put it in low speed and test for voltage coming off the board to the pump.

There is no power to the pump when I press the switch for low, but I hear the circuits activating. If I press it again when the circuits are active I can sometimes get it to jump into high speed. When the tube is initially re powered on(circuit breaker reset). I can always get to pump to jump to high when I here the initial circuits activating and trying to go into low speed startup buy pressing the start switch once.

Since the pump is not getting power when activated but will run on low speed sometimes I don't believe it's the motor. I am more focused on the low speed relays on the board causing the problem. Since you can hear the relays click like they are trying to activate when you push the top side button for low speed this makes me think the top side is working and again leaning towards the circuit board.

I am experiencing similar problem with a Marquis spa. Could the problem be a failed start winding? I have changed the start capacitor after detecting it had failed (visible indication of leakage). Yet after replacing start capacitor operation is same as what Anonymous has described. I do not think it is the control board because I can hear the relays clicking, and I have also used the spare relays for pump two which my tub does not have.
