Portafilter making contact

Hi everyone

My rocket portafilter are making contact with the metal

The stock gasket is 8.5 mm

I tried an 8 m

Both make contact

The 8 just let’s me turn till its at 5 o’clock

I wonder why

It wasn’t like this before

Thank you

hedonist222 - Sorry I don’t know what you mean by “make contact”

Video?

Grinding sound/sensation

It’s hard to say anything. All I’d do is:

Replace a gasket like for like. It it was 8.5mm, replace with an 8.5mm
I’m assuming you haven’t changed the portafilter too, and are using the same ones which came with the machine;
Make sure the screen/gasket is sitting correctly;
Make sure the PF, gasket, group is clean and free of debris/coffee grinds or other residue;
Portafilter should lock at 6 o’clock;
The lugs of the portafilter will touch the inside of the group where it slots in.

What would cause a grinding sound /sensation?

hedonist222 Do you mean you put in an 8mm instead of an 8.5mm gasket, and now it doesn’t turn as far as before?

With an 8mm gasket it should turn further? Is it fitted correctly

Hi Dave

With the stock 8.5mm, I could feel/hear the metal from 7 o clock

I thought maybe it was too thick

But even with the 8m, it still touches metal

Why is there a metal on metal sensation?

It wasn’t like this before

what changed? Surely the portafilter lugs did not grow?

Not sure

It was never like this on my Appartamento

Till a few months ago

I sold my Appartamento and got a cinquantotto and it’s still grinding towards the end of the rotation

I find it hard to say anything. The best way would be (as suggested on my first reply) to make a video describing the problem.

It might be a non issue, it might be something that you have placed incorrectly.

If you do decide to video:

Please show us you locking the portafilter, and any noise it makes.
Please film underneath the group, so we can see the shower screen and the group, specially where the portafilter engages;

As mentioned before, make sure everything is clean (clean the group with a brush and water). Also make sure the gasket is not upside down.

Looking forward to your video. But without it, I’ve run out of ideas.
