The old wet puck thing
L1/new -type group seals/IMS screen and basket
18.5 grams bean
I pre-infuse until it drips and pull shot with 27-30 second target
Lever usually catches around 45 degrees
Recently pucks are wet/soupy
Don't know what to try.
Any suggestions would be appreciated....

What L1 do you have. Is it the big commercial machine with pre-infusion of line pressure or the older version of what is the L-R now with pre-infusion at boiler pressure?
In an 18g basket I assume? How fresh are the beans? Dark/ light roast?
You say the intention was 30g espresso in almost 30s, right? Is that also what you got?
Is that a problem for you? Is the espresso okay?
How long after pulling away the cup to drink it, do you wait before you take off the portafilter?
I guess it is the 18 g basket..
Beans 2 weeks from roast
I'll weigh the output
Shots are...ok
Just never had soupy pucks before
So in terms of delicious shot there's no issue.
The puck is there to throw away so how it looks is also not a problem ;-)
My guess it's this specific bean. It might have been roasted faster or lighter or both, needing a finer grind and the remaining air pressure above the puck after preparing your shot is not big enough to push the last water drops out through the dense puck and leave a dry puck. Some of the last grams of thin coffee water that normally would fall into the drip tray are now still in the puck, being harmless all the same.
Cheers
how long after the lever stops moving are you releasing the lever?
if you pull the PF immediately it is going to be soggy every time
if you pull the PF 30s after the shot completes it should be dry; if it is still soggy the dose is too high/grind too fine
kind regards
reiss.
was the beans. I have been using different ones and the wet pucks are pretty much gone.
