it also gave me a SC565 hence did this bit as well. and about putting machine the on fire, customer might summon me later. :P

right, so once we are inside the motor, we can come to a conclusion.

if you are familiar with electrical drives, may be you can spend a couple of hours to service the pump if it is in half working condition. Else, replacing is an affordable option.
