If this doesn't clear it DY then I would look into the pump.

Took apart and inspected impeller closely, all fins look perfect, started up pump, runs perfectly smooth and quiet. So, is there a way to check if I was sold the correct M7 sensors by the local spa store. They took the sensors off a heater assembly, but the odds seem so slim the exact same error message would come up. No partn number on sensor, just a serial number.S/N 30382***1005130428.
The same place sold me the heater element which cured the original GFI breaker tripping. Thnaks so much for your help and time!

That is the correct sensor, what you can try is switching the two sensor at the circuit board, plug A into B and B into the A position on the board. Sometimes by switching them it will work.
