- When it comes to giving your espresso machine a long and happy life on your bar, preventative maintenance is crucial. Regularly replacing worn-out group head gaskets is an important part of that maintenance, since the gasket creates the seal for your portafilter. From identifying signs that your gasket needs to be replaced, to covering the tools that you’ll need to do the job, we walk through what you’ll want to know about caring for your gaskets so you can keep the great shots coming for a long time.

for those of you where the gasket didnt just glide out there, I used a small screw to wind it partially into the rubber then pulled it out. Worked like a charm
Had a Quickmill Silvano machine for 10+ years and never had to replace it, I think the key is, I didn't leave the machine on when it wasn't in use, and I didn't overtighten the portafilter, and didn't leave it locked in when the machine wasn't on.
Excellent guide, thanks! I haven't done this for 15 years, so I needed a reminder, the last time I did it the old gasket was baked on really hard, it took ages to remove and I fear my next one will be a challenge too, as it's a very old machine that I bought used.
Thank you. I watched it twice and did it once. I used coconut oil as a lube worked perfectly. Thank you.
I’m commenting bc I come to this video so often and to save myself from having to skim the video: flat side touching portafilter
Love it!
I had no idea. My gasket is over 10 years old. It’s like a hardened puck.
Great video. Very informative!
Thanks a lot the lubricant part was what I really was missing
Hi there need help, when i put my portable filter inthe group head is very tough to tighten and i suspect the rubber gasket didnt sit properly inside. However, i an having a hard time remove rhe rubber gasket and when i use the tool to glide open, the rubber chip off from the gasket. What should i do to remove it easier
I've dismantled the machine and removed the shower screen and holder. I've got the group mounted in a vice and attacked it with an awl for about 10 minutes and the old gasket, completely cooked, is coming away in small sooty chunks. What do I use next: a Dremel to grind it away with a grinding bit, or a small chisel? Any help would be appreciated.
my problem was different, this is my first time work with this appia 2, and the problem is the manualy button was always blink (flashing), i just try to leave it about a night and turn on the machin in the morning, I hope the machine is working normally but, the flashing thing is just keep blinkin at me, I hope you guys can help me please, its no matter if I use manually but this problem make me so curious, what's wrong with this. so guys help me :(
Thank you so much for this video, very clear and informative.
Thanks you so much
Thanks mate
whats the next 2 steps beyond brittle? thats where mine will be at work as the technician refuses to service the machine for some reason and keeps re tuning the grind so the puck is touching the screen, am i missing something?
Great video, thank you for sharing! Where can I find these tools and the lubricant? Does the lubricant purpose to easier slide the new gasket? Does it affect the coffee taste after the installation?
Any major hardware store will carry an awl and Dow 111 lubricant. The lubricant makes it easier to fit the gasket in, but it may not be needed. You should try without it. If you use a silicone gasket like a Caffewerks you are even less likely need lubricant. Food safe lubricant should not affect the taste, but it's good to flush the group after install. You need a very, very small amount of lubricant to begin with.
@@primacoffeeequipment I’ll give it a try, thank you so much!!
Was absolutely heartbroken when I thought my machine had died, I loved it for the longest time and recently noticed a little water coming out around the top. Cleaned it and let it sit for a day. Today the portafilter went to the 4 oclock position and water went everywhere no water through the shot at all. Thankful it is just the gasket but goodness am I worried to see the state of my old one! Wish this was more common knowledge ❤
Yea, it's super important to get those replaced consistently! Hope everything gets back up and running soon with your machine.
E183?
Can you give me info about of glue ? Link, name etc.
We use DOW 111 food safe grease as our default. It is a lubricant, not a glue.
Hello! Could you repeat the 2 reason to change a gasket? I didn`t understand all words. I currently have a leak problem when i insert a portafilter. Thank you!
Certainly! Ryan is saying that over time, the gasket will compress and shrink, so the portafilter will need to be tightened further and further in order to create a seal. He uses the example of a clock face - where the 6 o'clock position is facing directly toward the user, perpendicular to the machine. Over time, a portafilter may require tightening to the 5 or 4 o'clock position (or 6/7 o'clock on some machines). This compression is a sign that the gasket may need to be replaced soon, and can contribute to issues like leaks or pressure loss as you may be seeing on your machine.
thank you so much for this clear reply! Now I understand. Because I didn`t understand before the standards of the portafilter position. In my machine it was sometimes 5 o`clock or 7.
Hi! Could an old gasket result in inconsistent shots? My shots are taking 10 - 12 seconds to drop but then run very fast. Thanks!
Is the lubricant needed? In the online instructions for Slayer, they don’t mention the lubricant. Just wondering.
Carlos Palacio no need
But you are showing the side that is not flat as the side facing the portafilter, so does the side with the groove needs to be touching the portafilter or the bottom of the machine? Also when you are taking out the gasket I can see that the grooved side is facing down where the PF is? So which one is correcT?
Another way to say it is that the side with imprinted writing on it should face up. Almost all gaskets have markings like this. The side that faces the portafilter is smooth, but yes it can be grooved.
Don't leave your gaskets in too long. I had to remove the group bodies from the machine and chisel them out 1/4" at a time. That's a real problem, so do this regularly.
Replace every 6 month ?
Mine is 4 years old and works perfectly well.
That's great! It depends completely on how much the machine is used and the person locking in the portafilter. If it still works, no need to worry about replacing it yet!
Same! My breville 870 is 12 years old and did 4 pulls daily. Just now replacing gasket.
Is lubricant absolutely necessary ??
It's highly recommended as it helps the gasket insert easier and seat correctly, as well as condition the rubber and maintain its flexibility and seal for a few months. In a home machine, re-lubicating once per year (or as needed) can also help keep the gasket in shape for a bit longer before replacing, though in a commercial environment it's about as cost-effective to simply replace the gaskets once they begin to wear out. Dow 111 and equivalent lubricants are quite cheap and a little goes a long way, so it's very easy to justify using them.
Thanks. Ive read mixed reviews online. some say the lube messes with the flavor of the shot. some say it doesnt matter if you are properly maintaining your machine. some say its an absolute must. i think ill try no lube this round and if i see it leak in less than 3 months (cafe setting) ill do lubricant next round.
ps: thank you for the video it was very helpful.
Would you be able to fix a grouphead leak by adding the lube? I can't seem to find anything wrong with the gasket or portafilter
I had to turn the machine upside down & drill into the rubber to get it to break up, bast**d of a job, getting the new one in was a pain too.
Probably better not to seat a rubber component with a metallic screwdriver!
You spilled some coffee on the side of your forehead
The reason to replace a gasket, is if you get leaking from the group head when pulling a shot. The weird thing about this video though, is he say "THIS IS THE GASKET". Right. Like as if all machines have the same gasket?! Even weirder, he doesn't even say WHICH machine he's replacing the gasket for!! I've worked on many different espresso machines, and I can tell you that about the only thing they all have in common, is the gasket is round. There are different methods to replacing the gasket in different machines because of their different designs. plus the gaskets themselves will be different. Ergo, this video is only instructive for the machine being demo'ed. Which.... is not named, as far as I can tell.
