I have an Arctic Spa. I put chemicals in and tried to start the "boost" cycle and heard a buzz and cycle shut down and read "Flo" in the display. I removed filter to find that it was clogged so I inst

The motor may have a thermal cutoff if the motor draws too much current. Do you have a sufficient large gauge circuit supplying the motore? If not the actual voltage at the motor may drop, causing it to draw more current to make up for the loss of voltage, thereby tripping the motor's protective breaker. I assume the motor will start again after serveral minutes of cooling down.

you must have a small pump call laing if you do, air picket inside the plumbing try to turn both pump on high and wait few minutes if doesn fix try to loose the nut just a little bit with the breakers off and let the air go out. try one more time. if doesn work turn on high both pump and touch if they are working then a impeller may be broken inside one of them try to turn each one separate to find wich one as t he broken impeller.

Hi Mohn,

Don't know your geographic location, but where I am we've been in the single digit temperatures for three days. Everything that can freeze has frozen.

If you are in a similar area, even though the water in the spa (I'm assuming the spa pump is being used on a spa) is heated, the pump housing isn't. If it iced up, it could very well cause the problems you describe.

Comment back with some more detail before I continue down what might be the wrong path.

Best regards
Mike

You will need to pull the front of the pump off then unscrew the impeller. The impeller will be set on the shaft and will take some force to break free. Hold ing the back of the shaft and using water pump pliers on the face of the impeller will usually work but sometimes I will wedge a screwdriver in the fin of the impeller and hit it sharply (not hard) with a hammer to break it free. Then the housing will just pull free of the motor. When replaceing, the impeller just goes on hand tight. Hope this helps and good luck.

Is your switch an "air switch" ... could be you have a leak in the hose that connects from the push button to the actuator that actually does the switching. Check it out.
