@EJ39 did you find a resolution ??

I just installed a brand new t115 model and it worked great for 1 week .
Then it would trip the breaker every single time.

Service tech came out . They narrowed it down to the compressor / wiring harness.
Then a aqua cal tech guy on the phone says to change the breaker.

I had a 50 amp gfci breaker on it.

He said you can’t use a gfci breaker with the heat pump ( wtf ??)

Replaced it with a non gfci 50 amp and no issues since …..

Heat pumps do not require a GFCI. Heat pumps fall under NEC 680.45 as a "circulation heater" which requires a GFCI when supplied by a branch circuit of 150 volts or less. Any pool Heat Pump that runs on 240 volts then does not require a GFCI.

Note that while a GFCI breaker is not required by the NEC for use with a heat pump some local codes may require it.
