I replaced an old 1hp pump that was still working but cracked and leaking with a new Hayward 1.5hp Max-Flo XL. I changed the jumper from 220 to 110 and checked and re-secured the three wires.
when I turn it on it makes a loud sound - there is some water movement then the breaker trips in about a second. The motor housing feels very warm. I have video if I can post it here.
Its possible it could be a bad connection in the wiring or breaker although it was fine with the previous pump. I am curious if a bad connection would make it start so loudly? Or would it be loud since it is not yet primed?
