10-15 second shots out of the blue
« on: October 07, 2017, 09:39:34 AM »
My Gaggia Classic/Vario has not been working right for a few days.
I get sink shots every time now. I re-calibrated the vario and no difference.
I did notice the filter handle will not turn in to the mark anymore with even an empty portafilter.
It stops before it even gets there. Maybe a problem there so I'm not getting enough pressure?

If your pf is locking before 6 o'clock, take out the gasket, clean up the boiler base and reset the gasket. If you are concerned about brew pressure,use your pressure gauge. Best guess is that your issue has something to do with your grinder.

Thank you! I think you are right. I checked pressure and it's good at 10. Do you just poke the gasket out with a screwdriver? I had to set my vario at 1e to get a good 30 second shot. Wonder why it changed like that?

Most videos available on how to remove the group gasket is for replacement and does not care if the old one gets damaged. Do it carefully if you intend to re use it. I like using a small spatula. Applying Molykote on the side that attaches to the boiler makes it easier to remove.

No experience with a Vario but based on what I have read about it, what you are experiencing with it is nothing new.

It would probably be a good idea to have a new gasket on hand before you try to take out the one you are using now.  That way if you have to resort to using screws to remove (and thereby destroy) the old one, you have a new one ready ;)
