Hi All - I have a Hayward power flo matrix 1 HP 2 speed pump I purchased new in August 2019. I run the pump on low speed approximately 11 hours a day via a simple intermatic outdoor rated dial type timer (the kind with the circular dial and on/off pins). Pump is plugged into timer, timer is plugged into outlet.
Pump was running fine all day yesterday. I noticed this morning that it was not on. The pump is plugged into a dedicated line fed by a 20 amp breaker that runs to dedicated single pole GFCI outlet. I noticed that the GFCI red light, that is on when outlet is working, was off. I unplugged timer from outlet, reset GFCI and light came on. Plugged in cord from timer and it immediately tripped the GFCI. I removed the timer, reset GFCI, and plugged pump directly into outlet and it tripped, even with the pump switch in the off position. I grabbed a floor fan, reset the GFCI, and the fan operates. I plugged the pump into another outdoor outlet on a different breaker and it also trips the GFCI.
I removed pump from plumbing and inspected impeller, and as best I can tell (hard to reach into hole) the impeller does move/spin.
I know motors can be tricky to diagnose, but are there any "easy" things I should check first?
Thanks,
Greg
