Hi all, just looking for a little advise, my 1972 Cremina is in very good working order but im worried about a small grinding/click noise i get with
lifting the lever up, only happens just when its reaching the top and is fine going back down, i have oiled it but makes on difference, the noise seems to come from the pistion/group head and not the pins holding the lever in place....
i love this machine and would hate to think i may be damaging it.. any ideas? Thanks

Hi !
How is the pressure when you make the coffee? Did you stop to use the machine for a while?
Maybe the small gasket inside the top of the group can be old and to dry, so it can make a strange noise... it can be different things.
If you can answer the 2 first questions, that will help me!
How old is the machine and when did you bring it for a check up? :) What kind of water did you put in, bottle water or regular water coming from the pipe?

Sincerely

Julien

I would speculate that the piston has come loose on the rod as a likely possibility.   Any deviation of the rod seal, washer, clip at the top of the group would result in a leak.   On the upstroke the piston goes a bit crooked and on the down it realigns in the cylinder...best guess not seeing the machine.
