Topic: SL90 shower head screen removal? (9 msgs / 133 lines)
1) From: The Scarlet Wombat
Okay, I've been convinced that I need to remove the shower head screen on 
my sl90 and make sure there are no stale grounds living there, waiting to 
sabotoge my god shots.
For sl90 owners, I could use a wee bit of help.  I feel the underside of 
the group head where the shower head screen is, and there is a very small 
slotted screw in the center.  Do I just remove this and the screen comes 
off?  I figure this is correct, but would rather find out before I delve in.

I think you are right, Dan. At least that's how it works on my Gaggia. Mine has a short flat-head machine screw in the middle of the shower head. Remove the screw and the screen should drop out or pull out with little effort. I have been using demi-pods (circles of filter paper on top of the puck) to keep the screen clean. It helps a lot, but some crud still gets into the group head -- don't ask me how.

You are absolutely correct Dan. Just be careful because as I remember, it is 
a tiny screw and kind-of wants to go it's own way when it's loose. 
Have you tried cutting a paper filter disk the same diameter as the inside of 
the portafilter to protect the shower head from the grounds? I read about 
someone doing this quite a while back and it does seem to keep things a lot 
cleaner. I would be interested in comments.

Thanks Terry.  No, I am not good with scissors and cutting a filter paper 
disk, while easy for some, is a monumental task for me.  I can write 
programs to guide moon rockets, but cutting a little disk daunts me.

I knew if I checked long enough I could find something that you would pass on 
:-) If you felt the edges of the disks I cut there would be no doubt it takes 
more dexterity than I seem to have. They only cover part of the grounds.

My method for cutting the demi-pods is to find  a circular object that fits 
the inside diameter of the basket. For my Silvia, a vitamin jar cap fits. 
Almost any cylindrical object would do....I then place this on a Melitta 
type cone  filter and cut around it with a small box cutter (an Xacto knife 
works well, too).
I have faith in you gentlemen to be able to do this after a few attempts. 
Just be a bit careful, at first.....
I can get about 6 filters from a #4 filter. You get two with each 
cutting...It shouldn't take more than 10 min, for the whole operation...
Have fun, guys...

Well, after hearing that I could be getting grounds up into the shower head 
in my sl90 by not tamping and letting the coffee pressagainst the shower 
head screen, I decided to take it off and see what lurks inside.
Nothing, not one bit of ground anything, clean as a whistle.
I always run a hot water shot through after pulling espresso or Americanos, 
and run cleaner through the machine once every month.  I guess I'll not 
worry about getting grounds up inside the shower head.

This is jut an untested idea, but it might work.
Wet the rim of the jar cap, and use it to make a wet circle on the filter
paer.  Then just rip the filter paper along the wet circle.  The wet paper
should rip very easily.

Or go to the local craft store and buy a circle cutter...
