If the group gasket hasn't been replaced recently I would NOT attempt to
remove the dispersion screen until you have the new gasket. FWIW the group
gasket is or should be a normal scheduled maintenance replacement item every
year or so depending on power on time (not shots pulled), 24/7 operation
every 3 to 4 months. Over time the pliable rubber gasket will become hard,
even totally brick hard and carbonized from the group heat.

The shower screen on my Giotto needs to be replaced and I have the new part.
The old shower screen is held in place by the gasket which may also need
replacing, but the replacement is currently backordered, so I don't want to
damage the one I have by using screws or other sharp objects to pry it out.
Is there some way to get the gasket out without damaging it?  I remember
someone on this list talking about a way to use the pressure of the machine
to help loosen the gasket.  Does anyone remember this?

The answer was from our own Mike McKoffee:
HB=home-barista.com, in this case the forum, sorry about that.http://www.home-barista.com/forums/viewtopic.php?t=1848Basically it's locking a PF with backflush blank in as usual. Let =
pressure
build 'til about 4 to 5bar then partially loosen PF then re-tighten. If =
you
let it go to full shot pressure good luck turning it loose:-) Repeat a =
few
times and the screen pushes the gasket loose! You'll be able to feel it
happen through the PF handle. Way cool. Some have said it's totally =
plopped
out for them but hasn't for me. For me it's been one side of the screen =
will
be seen obviously pushed lower, very slight almost no pressure prying =
the
side of screen basket and the screen and gasket then just falls out. =
I'll
say it again, WAY COOL! So simple no excuse for not replacing gasket =
every 6
months to a year pre-emptively before it gets hardened and becomes a =
PIA.

I am having trouble even getting the shower screen off my Livia, a  
non-e61 machine in which the gasket doesn't hold the screen in place-- 
I used to have problems at first, then for 2 yrs. it was easy every  
week, but now the screw will not budge whether the machine is hot or  
cold.  Since it's been a year since my last gasket replacement  
(extremely traumatic, see below), I am going to have to bite the  
bullet and use up the current tankload, bleed the boiler, and perform  
a gasket transplant. With the machine on its side for that procedure,  
I should have enough leverage to torque the screwdriver without its  
slipping out of the screwhead's slot.
Last year I performed my first gasket replacement. I figured I would  
just remove the shower screen, screw a regular hardware screw into  
the gasket, grasp the screw and have it pull the old gasket out, the  
way folks recommended. HA!  The screw wouldn't even make a dent in  
the ossified rubber. So I emptied the tank, bled the boiler, and laid  
the machine on its side. The gasket would not budge, no matter what I  
used to try to pry it loose, and it was hard as a rock. I ended up  
completely upending the machine, taking a steak knife and having to  
pound it into the gasket with a meat mallet (for flattening veal  
cutlets). I grabbed my trusty pliers and................the knife  
would not budge. There lay Livia supine on the counter, like a  
harpooned beached whale, with a knife through her heart. I ended up  
knocking the knife loose by pounding it sideways, and fortunately, a  
chunk of the gasket came with it.  I then had to chisel away at the  
ossified remains with a hammer and screwdriver, and once it was all  
out my kitchen had so much black rubber dust that it looked like a  
chimney sweep had gone berserk.  Fortunately, the replacement popped  
right in, the dust was wiped up, and the shower screen--having soaked  
in Cafiza far longer than ever before, came clean as a whistle.  (The  
grouphead dispersion screen--the middle layer of the "sandwich"-- 
still took some scrubbing, but at least all the holes came clean with  
only a toothpick instead of a knife point).
Oh joy. It's time again. Pray for me. Will order a new gasket tonight.

Put the screwdriver in the slot and lightly tap the handle of the 
screwdriver with a small tool or hammer a dozen times.  It will help loosen 
the screw in the threads.  Kinda like tapping the edge of a screw top jar to 
make it open easier.

Gaskets come out easier with the machine hot.

keep trying on the chance I'll eventually get lucky.

Tap it laterally or tap vertically up from the bottom? Tried the  
latter---still won't budge. Best I can do meanwhile is just keep  
scrubbing and backflushing and hoping for the best.

Tap in the direction like you're trying to drive the screw in like a nail.
But gently!  It doesn't take much unless the screw is cross threaded.

Well, I did finally get the screw out--the meat mallet didn't work  
either laterally or vertically; it took a lobster-cracker around the  
screwdriver handle to provide the extra torque I needed. But as I  
don't have the new gasket, I just did my usual thorough cleaning.   
The gasket will come out once the new one arrives.

First, make sure the screwdriver's blade is the correct size for the screw
head. On subsequent reassembly, Don't use terms like torque and leverage to
retighten the screw. It's probably stainless steel or brass, and either can
"gall" and jam if you use a lot of force.
What's a lot of force? With a small diameter, fine-pitch screw, you can
generate tremendous forces (Hundreds of pounds axially) even if you have a
weak paw and a screwdriver. If you tend to use two hands on the screwdriver
to tighten the screw, Don't!
This is not like a fruit jar lid! You may need an impulse screwdriver to
loosen the screw, but you absolutely require a good sharp blade of the
correct size.

Another little tidbit:
If the screwdriver is starting to slip - especially phillips - a little
automotive valve grinding compound will make a world of difference in
gripping potential.

I haven't used that stuff in 50 years. NAPA might have it?
I lie- I lapped in Tecumseh valves with Bon-Ami and motor oil.
If it's a phillips, run, don't walk, and get a new #1 or #2 dedicated stubby
for your group. Take the old screw with you to a hardware store and get a
couple of s/s phillips oval head screws as spares if the head of your old
screw allows the screwdriver bit to slip out.
With a new screw and new screwdriver bit, the job gets easy. With the
correct bit, a phillips screwdriver should be able to hang horizontally on a
phillips screw head. If it won't do it, save yourself grief and buy new #1
and #2 Phillips screwdrivers. Replace the screws too, if they're botched.
Never loan your Phillips screwdrivers.
