Capacitor change on grundfos alpha+

[Tricardo Picard]

Hi,

I need to change the capacitor on a grundfos alpha+ pump that looks like the one in the picture.
Does anyone know how to open the flipping electronics carcass ? … I’ve been struggling for 2 hours now. There are 2 screws , and 2 cllips … so far so good … then when pulling the carcass seems to get stuck with the speed control and there is no way to get it out . Any clues ?

Why do you want to change the capacitor

Why do you want to change the capacitor

Every so often it fails to start and starts pulsing.
It is not jammed, spins freely, no air locked in, spindles etc are clean … last try before I ditch it is changing the capacitor . Then again , maybe I’ll just get a new pump .

I leave it off and alone for a few hours and it then starts OK again … until the next time
