Question Tripping GFCI

Just wondering what could be the cause of a GFCI tripping when one closes the switch to the off position. A little more information: Switch controls a small pool cover pump motor - receptacle is GFCI and also protected by GFCI ckt breaker. I was thinking that having a GFCI at both ends was wrong. Any answers would be appreciated

I have heard of those complaing that double GFCI protection tneds to cause nuisance trips but it really shouldn't.

Is the motor 120 volts? If so, I can see a reason that it may trip GCFI protection.

While there is nothing wrong with two GFCIs protecting a circuit, it is not ideal either or standard.

The big issue is that a trip may not immediately be seen because the first GFCI examines may not be tripped.

I suspect an old or worn out GFCI. Eliminate the double GFCI, and if necessary replace the remaining device.
