I have been lurking in these forums for a few weeks and have finally joined this forum. I have recently bought a Saeco Aroma, refurbished, and a Ascaso i3-mini grinder. I have read many post's on the internet about depressurizing the Saeco PPF, yet nothing was very detailed. So, since I did the depressurizing procedure this afternoon I thought I would post some pictures so others who are wanting to tackle this mod could have some visual help. I figure this is a proper thread to attach it to.
Here we go:
Unscrew the three screws that attach the PF handle to the brew head and you should have the following image after removing the plastic handle.
Remove the white plastic piece from the metal portion of the brew head. To do this I was not sure how it came off, I just gently pried up with a small flat head screw driver and it easily popped off.
Then what you have left is the rubber stopper (if you wanna call it that) which the filter hits against. Just push down until it pop's out through the other side as seen in the following shots:
Walla!!! You have just depressurized your PF, for the most part
Still wonder if the hole that is left is still to small and yet allows some pressure to build up. Even so it is better than what it once was.
And the finished product:
I had time before work to pull a double shot. I was getting 10 Seconds with the pressurized mech installed the day before. I fine tuned my grind a bit more and packed it in at about 30lbs and was able to pull my first 21 sec shot with nice thick crema, but I still have a lot of fine tuning to do and will post a result later on if my efforts are more successful. It took some time before the espresso came through the brew head, it really made the machine work hard but once it started it was dreamy!! though I think it was either packed to hard or the grind was a bit to fine. EDIT: I forgot to mention that I was using a local roasters beans called "Red Eye Espresso Blend" It was roaster about 1 and a half weeks ago. I might pick up some "City" roast he has this weekend. The roaster label is called Grand Rapids Coffee Roasters http://www.grandrapidscoffee.com/
I am also thinking of locating a rubber O-ring to replace the reddish O-ring that sat on the outside of the existing rubber "stopper" to lift the filter basket up a touch. There is a small groove on the outside diameter of the inner portion of the brew head that looks like a O-ring would fit. So as i was writing this I thought why not see if I can take the reddish O-ring off of the plastic stopper and use that. Sure enough it come off and fit right in the groove like it originally was designed to do.
Thanks everyone for sharing. I am enjoying learning about the fine craft of espresso.
