Anyone around who has experience with magnet valves? I got one here (in a coffee machine) that buzzes loudly when active, is that a sign it’s going to bite the dust soon? Any suggestions for fixes, like repeated descaling, or simply giving it a good whack? Or save myself the hassle and just get a replacement part?

I know some folks open them, clean them and change o-rings, etc. If it’s not hugely expensive, I’d personally replace it when it goes. I don’t know if buzzing is a sign of death but the ones in the espresso machines I’ve handled did not emit audible noise other than the loud clicking when they switch.
