Sundance Altamar Pump Issue

Sundance Altamar (2000) – I was doing a cleaning and re-fill and upon restarting the hot tub, I was getting a FLO reading and the #1 pump would not start. When I did the clean-out, I sucked as much water out of the tub with a shop-vac, I did notice that the flow valve did not have any water in it upon start-up, but once I left the small heat pump on for awhile, the flow valve was functioning and the FLO reading went away, however pump #1 would not start up. When pressing the button for the #1 pump, I can hear a click noise and I can hear the pump humming, but pump won’t start. After a few seconds, I hear another click noise and then no humming, which I assume is an internal breaker or safety switch that is shutting off power to the pump. I have confirmed that the pump shaft will turn quite easily, thus not a seized pump. Any ideas on what the problem might be. Could there be an air lock that could be the problem. Could it be a capacitor in the pump or on the circuit board.

    Jay if you can hear the pump humming and you have proper voltage on the PWA where the pump connects to when there is a call for the pump to run you have either a bad capacitor or bad pump motor or both. If all else fails contact our Service Support Desk to book a diagnostic and repair of your Sundance Spa.
