This will be the 5th season for my Hayward 1.5hp 2 speed pump. When I switch it to high speed the pumps shuts off after a few seconds and then restarts only to cut out again. The problem seems to be intermittent, some days it will run on high as long as I need. I felt the motor body and it is not hotter than usual. Could this be happening because of low voltage? I have had it temporarily plugged into a power strip with a built in reset breaker. The pump will run on low speed fine. Thanks.
