    Sundance Spa - circ pump works, heater works but Jets will not work

    I am trying to get my Sundance spa( i think a Marin model) up and running after being down for the winter. When I engaged the main breaker to my spa, I had the FLO message on my display and the small 1/20 hp circulating pump motor was very hot. So I bought a new motor from the local dealer, installed the new motor and the FLO message disappeared and the circ pump seems to be circulating a very small amount of water. I turned on the heat and the water has heated to 100 degrees, the air bubble system works but the jets will not come on at all. This model has 2 level of jets and my display shows the jets to be on but no water comes out of the actual jets. When I check electrical power to the main jet motor(it looks as if there is only 1 motor) it appears to have power at the motor. Is there a switch or a relay that may be bad that is not letting the motor engage the pump at either speed?

    When I uncovered the spa in early spring I did notice that some water had leaked in through the cover and had frozen in the bottom of the spa(about 4 inches). The spa does not appear to be cracked or leaking.

    Are you saying that the main pump motor has power but isn't running? Supposing that it's a 240 volt motor, did you check both legs?
    If it has power then the motor is probably bad.

    Did you check the power to the motor at the lugs on the PC board or at the back of the motor? Make sure that you know whether the motor is 110v or 220v.
