Question about Rule H53sp 24mgra Swimming Pool Cover Pump Centrifugal Computerized
I just installed a new 2-speed 2hp A.O. Smith spa motor for an inground spa. The low speed works fine but is not strong enough to prime the system. When I switch to high speed the pump runs for 2 seconds then shuts down. Electrical circuit does not trip so it is wired correctly. Any ideas?
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.
