Changing a Group Gasket on a Rancilio Espresso Machine
Step by step instruction on removing &replacing a group gasket on most commercial Rancilio espresso machines including the Rancilio Silvia home machine.
Also, when your doing the final fit with the portafilter handle, first start using no basket. Once the handle fits into the grouphead with no basket then you want to insert the basket into the handle and then tighten the portafilter handle. Best of luck!
Before inserting the new gasket ensure that all debris is removed from the grouphead. Sometimes bits of the old gasket will stick to the grouphead. Then, before inserting the new gasket wet it with water. Mock up the gasket and slowly work the gasket in using a 5mm hex key. You want to start at one point and push in the gasket a little bit (not all the way) and continue pushing the rest of the gasket working in a circular motion. Continue this till the gasket is completely in the grouphead.
Just done it as per your instructions and the portafilter wont fit now suggesting the gasket isn't seated properly. Ive tried the technique of moving one of the portafilter clips around the rim but still to no avail. Thoughts???
If it's still intact then another trick is to use two drywall screws and tighten them into the group gasket. Get screws long enough that after tightening them into the group gasket the screw head sticks out past the grouphead. Now use a pliers to pull the gasket out with the screws.
If this doesn't work, you would have to just keep chipping away. Best of luck!
