Hey, guys. My Elizabeth has started leaking water from the group head when pulling shots. Would this be caused by the red o ring or the black gasket? Or should i just replace both? FYI - i have removed, cleaned, and reinserted both to no avail.

If you search back this has been covered by someone else in the last month. I can't remember the user however

Hard to diagnose with words. A close up video clearly showing where the leak is coming from would be ideal. Ps: best of luck sourcing that red o-ring, specially after Brexit. Good news is that's unlikely to be that.

@"MediumRoastSteam"#p51927 Will post a vid in a bit…looks like BB has the o ring in stock.

@"Cuprajake"#p51926 I did a search before and have just tried again, but i cannot find said post unfortunately.

@"europa"#p51924 - it's quite hard to search for content in this forum. Presumably the water is leaking from outside the portafilter., Rather than from the top of the group. - when was the last time you changed your group gasket? - when did you last removed and cleaned it? - did you placed it the right way up? - is it a silicone (red) or rubber (black)?

I’ve never changed any gasket. The machine is about 2.5 years old.

I took them out yesterday and cleaned them for the first time. As mentioned, i took out both the red (silicone) and black (rubber) gaskets. Pretty sure i put back the correct way, but the leak had started before i removed them anyway.

That thread i have seen, but my leak is from lower down in the group head, hence why i assumed it’s the red o ring. Here’s a video:

My bet is the group gasket. See post above.

The leak in the other thread is from the top of the group gasket. Mine is from the bottom.

Edit - just seen your latest post - thanks ! :-)

Time to change the group gasket. Make sure the group is clean and free of coffee gunk all around before you put it back. Carefully replacing the red o-ring and make sure it’s correctly in place when slotting the dispersion plate back on.

I recommend the cafelat 8mm red silicone gasket.

So, only replace the original black gasket with the cafelat one? And keep the original red o ring?

europa yes

Have a look if that red o ring is seated correctly also. I have installed shower screen holder to group head once without realising that o ring wasn’t installed properly. And black gasket is smooth face down.

Guys, just a quick update to say that swapping out the group gasket did the trick. Many thanks again!

Did you go stock or cafelat,
