    Cleaning the E61 grouphead shower screen

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Fellow E61 grouphead owners, do any of you have a good way of getting the showerscreen/filter out?

    I recently tried to get the showerscreen out, and ended up damaging it. Fortunately I had purchased a spare.

    The method I used (which worked before), was to pry out the rubber gasket with a flat tip screwdriver. Once that is lose enuf, I pry at the showerscreen.

    This time round, I damaged the showerscreen.

    Anyone have a better methodology which does not result in either the rubber gasket or the showerscreen getting damaged?

    Re: Cleaning the E61 grouphead shower screen

    Realistically, if you use group head cleaner occasionally in home use there is no need to remove the shower screen and group seal...the cleaner dissolves away the grunge leaving the shower, group head and solenoid valve quite clear and clean.

    Trust me, its a waste of time and just costs you money in having to replace the seals unnecessarily when you cant get the old heat affected seal back in, or when you damage the shower!

    If you still want to do it, sharpen a screwdriver to a point ( ice pick!!!), jab it carefully into the side wall of the shower (NOT of course into the groove between the bottom of the shower and the support ring welded over it, or you will be looking for a new shower), and using the group itself to get leverage on the screw driver, push (into the shower) and lever it down at the same time. Once you have it "started", move the screw driver around a bit and do it again, then move it around and do it again, in that way prising the shower down a bit at a time around the group until it comes out complete with the group seal still around it. The shower is only held in place by the group seal as pressed into its groove, and any resistance to you prying it all out is derived from how much affected by heat the seal has become and how hard it is wedged into its groove. The shower itself just sits suspended by the seal.

    There is precious little to see behind the shower. There is one only exit jet for the brewing water to come straight down through in the middle of the group, and a "slit" cut across this jet to distribute the water horizontally away from the hole, and from there the "even" distribution of water is taken care of by the shower screen itself.

    Err, hope this all made sense, it can be quite difficult to describe in words that which can be demonstrated easily in about 5 seconds!

    Maybe I can see if I can post a couple of pictures to this thread...now that will stretch my technical expertise a little!

    Regardz,
    FC.

    As FC said, you shouldnt have to remove the shower screen and gasket as part of normal maintenance.

    That doesnt mean the gasket will last forever and you should take note of how far the handle locks into the group as it is a good indication of how tight the seal is between the handle and the gasket.

    I started to get a bit of leakage which was due to the gasket no longer being flexible enough to seal the basket fully. The gasket will become rather hard over an extended period and can be quite awkward to get out without damaging the shower screen.

    If you start to have leakage problems, buy a replacement screen and gasket. They dont cost much and replacing one every year or so (depending on usage) is not a big deal.

    Re: Cleaning the E61 grouphead shower screen

    Thanks for the tips guys, I should probably get a grouphead cleaner. However, when I took out the gasket I also noticed that some of the coffee grounds had crusted onto the gasket, and required some rubbing to get it out.

    But I did exactly what FC said not to do, pry into the groove between the bottom of the shower and the support ring welded over it. I got away with it 3 times, but 4th time round, i pried the support ring away from the shower screen.

    Hi,

    I managed to buy a small kit of s/s probes that look a bit like Dentists Tools from Jaycar a long time ago and have found them to be very handy for this type of work. But like you, I have more or less decided that this is a bit of a waste of time as after a thorough cleaning session with Espresso Detergent, the whole Group Assy, PF, Shower Screen, etc is sparkling clean.

    I thought I would reduce this effort to just once per year in case something may be building up in there and needs direct action on my part. My feeling is though, that this will turn out to be unnecessary also. Maybe stretch out the time period by six months each time until I actually find something that needs doing. Ah what the hell, keeps me off the streets anyway,

    Cheers,
    Mal.

    Been hankering for an E-61 for a while now, so Ive stopped flushing my "Sunbeam Ladyshave" (thanks LochNess) and have been severly mistreating it in an attempt to bring forward "E-61 Day" but it just wont die. It mightnt make the best coffee, but jeez its tough!

    Tim,

    Open it up and start dropping a screwdriver accross randomly selected contacts in it. That sould do the job nicely. :o 8) ;D

    Grind finer and really choke the machine. Eventually the water will find an alternative route out of the plumbing or the pump will fail which will be too costly to repair.

    Tim,

    Maybe try flushing with nitric acid and when questioned by the CFO you can claim you thought it would do a better job than citric acid. ;D ;D Just dont spill any on yourself! And be sure to stand FAR away with lots of open windows when you use it! In fact youll probably want to have your running shoes on and head outside as soon as you hit the switch with a rope tied to the power plug so you can power the beastie off after it expires. ;D :o ;D

    Wired,
    Yes I see that I have managed to choke it nicely since I bought my MM, but Im afraid something will give in a major, nasty way and the little bugger will have the last word by hurting me as it dies! :-)

    Java,
    You need to take the aforementioned solution and market it in a wooden crate with the words "ACME" stencilled on the side ;D ;D

    Seriously, its beginning to drip a bit and those silly green lights on the front are flashing like a disco for no reason so I think its on the way out... (halleluja!)
