Subject: Porta filter won't lock down
 

I am Refurbishing an old Starbucks saeco Barista SIN006. I replaced the heating element in it and have put it back together.

Now, I cannot get the porta filter to lock onto the group head which it did before. It is real loose and wobbly when in place  and almost falls from the group head. I have had it (group head, not porta filter) apart about a dozen times trying to get it right. The big gasket seems to be in good shape, as does everything else on the group head.

Now, there are two plastic pieces that fit into the groove on the underside of the lip of the group head housing. Each of these pieces have a 90* hook on one end. I'm not sure how these play into this. I don't know if the hook stops the porta filter from turning or what?

Anyone have any ideas on how to get this porta filter to successfully lock down?

I am new to this stuff and am learning as I go. I did descale these parts when I had it disassembled. I did not take the porta filter apart and it did lock down properly before I started the Refurbishing.

Thx, for any help you can give me.

PS, I have Google and searched till I am blue in the face.

assemble the 2 halves and the portafilter locking ring  with the 2 grooves opening at 11 and 5 o'clock
and closed them with the bolts/nuts

then and only then
the boiler assembly gets mounted on the machine frame and locked in place  with the acorn nuts

Thx, Stefano. I will check this when I get home from work tonight. I don't know, but it is possible that I have the openings set at one and seven? I do hope it is something as simple as that.
Thx, again.

I wanted to post an update on the porta filter issue. When I checked last night, the porta filter locking ring is in the 11 and 5 o'clock position as you describe, Stefano. What I looked at next was the position of the main filter holder gasket. From the drawings, it looks to me like the wide diameter opening of the gasket fits up against the boiler unit and the smaller diameter opening fits against the porta filter. Putting it on this way, however, makes the porta filter very loose as I described earlier.

Turning the gasket over so that the large diameter opening fits against the porta filter instead of against the boiler seems to fix the problem. Is that the correct positioning of the gasket?

I do not get a steady stream of water through the group head. It just drips, only coming out of one hole in the porta filter. I do get good pressure out of the steam wand, though, so I'm hoping that the pump is OK. Even though I descaled the boiler when I changed the heating element, I will do a complete descale of the machine and hope that fixes the lack of a steady stream. I will also give the porta filter a good soaking again, even though I descaled it once already.

Descaling fixed the dripping issue. But, I still cannot get the porta filter to lock tightly properly which is causing over flowing and a mess. It did lock down tightly before I started working on it, and as far as I can tell, I haven't done anything to cause that problem.

The only thing that I think could be causing the problem is the gasket. It does look OK. It is soft and pliable. I've taken it off and put it back on a couple of dozen time trying to fix this problem. So, I  guess I'm asking if you think that a new gasket would fix the problem of the porta filter not locking down properly?

I will buy one if that is the problem.

Thx,

Thx, Stefano. Because of your response, I finally got the Barista working correctly. It took me 4 days of trying and probably a couple of dozen reads of your response, but I finally read what you said, all of your response, not just part of it. :-D

I experimented with three or four shots tonight after putting it back together. It works very well. Now, I will have to work on pulling shots. It makes good Crema. I was surprised. This is my first try with espresso, so it will take me a while to learn. I understand that there is a lot to work on, but I look forward to the journey.

Again, Thx loads for your help. Couldn't have done it without your response .

Frank
