<P><SPAN class=subheading>The life of a group head gasket is not a happy one.



All day it sits in a 90 degrees celcius group head, while the group handle also



at 90 degrees celcius is locked in against it (often with a good dose of ground



coffee), released and then re-locked in. This all means that your group gasket



has a pretty short life expectancy, which is shortened even more the greater the



number of drinks you make. When the gasket dies, you will notice coffee leaking



down the group handle when you brew coffee, and definately when you backflush



the machine (you do backflush, don't you?)</SPAN></P>

      <P><SPAN class=subheading>Below are some quick tips for replacing the



      group gasket on common machines:-</SPAN></P>



      <P><SPAN class=subheading>Wega - or any other machine with a Faema



      E61  group. <FONT size=+0>The E61 group is a massive chunk of brass



      (See Right), when assembled and ready to place on a machine it weighs in



      at 9 lbs. This weight mass contributes to its ability to maintain a



      consistent temperature. The other function that helps with this temp



      stability is the thermo syphon function; this is a function of water



      circulation that reduces hot spots within the group head. A very simple



      system that is worth its weight in crema. </FONT></SPAN></P></TD>

      <P><SPAN class=subheading>Turn off machine. (This operation is best



      performed when the groups are hot) </P>



      <OL type=1 start=0>



        <LI>Crouch down and look up into the group (with the handles removed),



        you can recognise an E61 group because there is no screw in the centre.



        <LI>Once you have confirmed there is no screw in the centre, take a



        small screwdriver and use the end to lever against the side wall of the



        silver diffuser. Alternatively take a large wood screw and screw it into



        the gasket (see right), then use pliers to pull it down and out.



        <LI>Working around the circle where the group handle locks in, lever



        down from the gasket working your way around.



        <LI>With a bit of work, the silver diffuser will start to work out,



        pulling the gasket out with it. Once the water breaker screw is exposed,



        scrub it with a metal bristle brush and the flat plate around it to



        clean it of coffee residue.



        <LI>At this point you can replace the gasket only, but it is best to use



        a new diffuser as well.



        <LI>Slide the new gasket up the diffuser from the mesh end up. (See the



        seperates right and then them combined)



        <LI>Put the diffuser and gasket combo into a group handle mesh down, and



        then push into the group - making sure the locking notches are in line



        with their slots.



        <LI>When you can twist the handle to the right as normal, the gasket is



        fitted correctly. It will be tighter then before.



        <LI>Do not push the gasket in with a screwdriver or it will be damaged



        straight away. </LI></OL>

    <TD>The other type of diffuser and gasket combo are pictured right, you



      will know if your group is of this type by looking up and seeing if their



      is a flathead screw in the centre. If so unscrew the screw and lever the



      diffuser down and it will drop out. On some groups (particularly Gaggia



      machines) you will have to remove the breaker plate - this has two Allen



      Key screws which you will need to undo and remove the big chunk of metal



      known as a breaker plate. Soak this in cleaning powder and hot



      water to remove built up oils. If you can see allen key screws in the



      group their is no way you can get the gasket out without taking the



      breaker plate out. If their are no screws or you have taken out the



      breaker then screw a long wood screw into the gasket until it is tight,



      and then use mole grips to grab the screw and pull it down, which should



      pull out the gasket. It might take a few goes, and the longer the



      gasket has been in the group it will be brittle and hard like pot. Once



      the gasket is out, use a metal bristle brush to scrub the metal plate



      clean of coffee oils, and make sure the gap where the gasket goes is



      clean. Push in the new gasket, then re-fit the breaker if present and then



      screw in the new diffuser plate.</TD>

  1. Unplug the machine<BR>2. Remove the reservoir, drip tray



  and drip pan and lay it on its back.<BR>3. Use a short wide blade screwdriver



  to remove the shower screen. Under the shower screen is a “water jet breaker”



  that will come out with the shower screen be careful not to lose it. If you



  use a small bladed screwdriver it might strip the screw.<BR>4. Find a couple



  of screws that you might have lying around. They do not have to be any special



  size. Screw them into the old gasket. I have found that a sheet metal screw



  with a 5/16”or 1/4” six sided head and a ratchet works perfectly. Make sure



  that they are across from each other. Do not go completely through the gasket



  just screw them in far enough to get a good grip. You can judge this by



  looking at the new gasket you are going to install. The gasket depth is about



  5/16”.<BR>5. Use pliers to pull on the screws and work the old gasket out.



  Pull one side and then the other until it comes out.<BR>6. This is a good



  opportunity to clean the shower screen and brew group. The cleaner they are



  the better the coffee. It does make a difference.<BR>7. Clean and dry the slot



  in the machine that the gasket fits into.<BR>8. Slide a new gasket into place.



  Make sure the inside edge that is beveled is facing up.<BR>9. Install water



  jet breaker and shower screen.<BR>10. Tip the unit back up and install the



  drip pan, drip tray and water reservoir.<BR>11. Fill the reservoir and plug



  the machine in and you are ready to go.</BLOCKQUOTE>
