Hi All,
Recently my Silvia has started leaking clean water from (I guess) around the grouphead seal when I try to pull a shot.
Background information...my Silvia was away for repairs for a week (nothing to do with grouphead) and I bought a bottomless portafilter as a welcome home present for her. On her arrival home, I also thought it must be time for me to clean the shower screen for the first time (She’s about 4 months old) so I unscrewed it (without any screwdriver mishaps; couldve done it with my fingers), soaked the parts in cafetto and put them back properly (finger tight screw).
Then I turned her on, let her warm up and had a go with the bottomless portafilter. The shot looked pretty OK but there was clear water running down the handle and sides of the porterfilter. It was a pretty low dose and I didnt choke it or anything. I then tried with the normal basket and also got the same normal looking shot in the cup and a small amount of clean water dripping out (something that had never happened before). I pulled the screen etc back out, double checked things and screwed them back in; all seemed fine.
I had a search through coffeesnobs and thought that I might need to put a bit more muscle into it, which I did, and the water stopped dripping out with the normal portafilter (strange because I’d always locked it in fairly loosely (i.e. not heaps tight) and had never got leaking before) but I still get a bit of dripping with the bottomless portafilter (drip, drip, drip from where the handle meets the body of the portafilter) even when I’ve locked it in very tightly.
Also, I’ve noticed that while I’m running water through the group to warm things up, water often stops coming out for a few seconds before resuming again. I *think* I’ve seen this before, but I think it seems to happen a bit more frequently in the last few days...or i might be imagining the increased frequency.
Also, my husband used Silvia this morning and when I got around to using her, the filterbasket seemed to have ‘stuck’ to the grouphead seal (it hasn’t happened before). I think he locked it in too tight after using it but then I thought that it might be because there’s something strange happening with the seal…
1) Did I screw something up when I put the screen and parts back?
2) Could something have been damaged while in transit/being fixed…I don’t think this is likely because I’m pretty sure Silvia didn’t go to the likes of northshore hospital!
3) Should I replace the seal? It’s pretty new and I haven’t been too rough with it.
Any advice?
Thanks Guys!
