There is no reset.

What was the nature of the pump failure? As you may know, a wet/shorted pump can damage the motor controller board.

Check the motor wiring harness for continuity. Take a resistance reading across the three motor phases at the controller end of the leads. Should be 32 ohms on all cross-checks.

Visually confirm the rotor position sensor module in the motor is not corroded or otherwise obviously damaged. Unfortunately there's no way to test the RPS without a special tester/tool from F&P. It can be replaced if suspect.

No problem found at the above points ... replace the motor controller board.
