Hey everyone, I've been working on fixing up an old nuova simonelli musica that was given to me. I replaced the boiler and did a decent cleaning of the whole thing including all pipes and solenoids. However, when I turned it on for the first time, it didn't draw any water from the tank. I tried some things to troubleshoot like manually priming the pump with a syringe, lifting the steam lever and repeatedly pressing the brew button, and lifting the tank in and out but none of these worked. So I decided to replace the pump and at first that was promising and it looked like it was drawing water, but then there was a leak between the pump and bypass valve (see pic, was leaking at circle), so I changed the o ring and tightened it up and now it's not drawing any more water. Did I tighten it too much? What else could be going on? Am somewhat of a beginner on fixing things so am a little confused. Thanks for any help, can add more images if that helps.
I've narrowed down my problem to the bypass valve (I think this is the same as OPV??). When I disconnected everything downstream and upstream from the pump, I was still met with resistance when I tried to manually prime with a syringe. When I took off the bypass and primed, water went through easily and the pump made a distinctly different noise. I've already descaled the valve and it did not help. So my question is, what can be done about this? Should I just buy a new bypass? New o ring? Try descaling again? Is there something else I can do to the bypass? Thanks for any advice.
