So sorry guys for not responding so soon been busy with school.

The valve in the piston is not stuck, because when I pull the lever w/o portafilter water is coming out,and when I pull a shot coffee is coming out but no resistance in the lever, and I have to hold the lever all the way to the end posittion.

There is still the "sound issue": any strange sounds, like water bubbling back into the boiler?

Could you post a video from a pull without pf and one with pf/coffee?

Hi
I don't hear any bubbling sound when pulling the lever, or anything.
18.5g and here's the coffee cake after shot,wet and soggy.

When you restored the machine, did you use the original fibre washer type ? Were they new.

no, I replaced them with rubber and paper shim.

Just to be clear. How many rubber gaskets and how many brass V rings are there ?
Would you have a photo of your assembled gasket stack ?

3 V gasket, 1 V brass ring,couple of paper shim and fiber,total stack height is 80mm.

Thank you

Ok. Now I know what is causing your problem

For the gaskets to work they must be seated on a V brass ring. Without that ring they will not seal.

So you need 2 more V brass rings to make a total of 3.

The image only shows the extra 2.

PM me if you need to buy some.
