My Pentair pump (new 2018) is tripping the dedicated Pentair GFCI breaker. This first happened a week ago after an electrical storm in our area. I was able to reset the breaker and operated the pump without issue for several days, and found the breaker tripped again yesterday. The breaker would not reset (trips immediately). The contractor who installed my pool & equipment in 2019 suggested that the breaker might be faulty, so I replaced the Pentair with 40A dipole with the same model with no change in results. My pool contractor believes that the 4-year-old Pentair pump is likely the issue and suggests replacing it (BTW, the model is Pentair P/N 011056), mfg. date 12/2018. My question for the kind experts here is -- are there other potential causes of the breaker trip other than the pump? Any troubleshooting suggestions prior to committing to a pricey pump replacement? Pool = 15,000 Gal+spa/heater; SWG. Thank you!

Perhaps the problem (current leakeage to the ground) is in the cable connecting your subpanel with the pump? Disconnect both ends and measure the resistance between the black wires and the green one.
First, put the 20A breaker back for safety. Turn breaker off, disconnect power at the pump, turn breaker back on. Does it reset? If yes the problem is the pump. If not, look for a frayed or broken wire.
Thanks for the suggestion. I've tried to reset the breaker (it's 20A, not 40A is per my earlier statement) after power disconnect at the pump, but it trips immediately. Moving on to wiring checks. Thanks again!
