I have an 809 that I bought from someone retiring. It has always run well for me. This past weekend I had some issues with air locks causing free wheeling. Whenever this occurred I would immediately shut the pump off. I then would find it would not restart and I would notice the fan would pulse when the switch was turned on, but it would not turn. The fan was magnetically held in place. After a few minutes (potentially as the motor cooled) it would run.I had a similar issue with mine. I took the head off and found that the impeller body had expanded and was binding inside the head. Maybe time for the 815 impeller upgrade?
Is there a potential dead spot in the motor windings or could it be overheating?
