If the puck is soggy It means you are underdosing.
You need to get the Dose right *and the Tamp right before the grind adjustment can be determined or made.
Buy a Kg of cheap supermarket coffee and put a few hours aside to practise.
When I had the EM0480, my technique was to 3/4s fill the PF [about as full/high as you could go without spilling coffee].
Then tap it on the bench several times to settle the grinds,
Then continue to fill untill a "mountain" of coffee towered above the top of the PF and began to spill.
Once filled, tap the PF on the bench lightly to settle the remaing grinds then gently distribute and level the grinds off with your finger.
When its basically flat, gently place the tamper on top [use only its own weight] to level the coffee.
Then Tamp @ around 13kg..
Tamp on your bathroom scales to verify you have a pressure of 13KG. +/-1 *Kg is ok, but if you want make consistant coffee you need to practise this and check regularily
Use a "real" tamper that fits the PF well [suggest you check out site sponsor: Pullman Tampers], the crappy plastic one that comes with the machine is basically useless and could well be a contributor to youre problems.
The tamped [compressed] grinds in a correctly dosed & tamped Silvia double basket should end up *about 3-4mm below the top of the basket.
You should feel a slight resistance [compared to inserting an empty PF] when you insert the PF into the group.
Furthermore, before you pull the shot, *remove the PF and check to see if there is an impression from the shower screen screw.
If youre getting the showerscreen screw impression, your dose is right.
I threw that stupid spoon/tamper away, and strongly suggest you do the same, but at a guess Id reckon youd use at least 4 spoons *[2 spoons...BAH! HUMBUG!] worth of coffee, to get the dose right.
Once you have the Dose and Tamp right, then you can look at your grinder settings.
When my sunbeam was new, a setting around 14 worked.
Others here, seemed to report a setting around 8, in my experience it depended which was the upper burr was assembled following cleaning.
Try 14, *if it gushes then try 8.
Once you have this starting point, tweak the grinder setting:
A lower number produces a finer grind which will increase the pour time,
conversely, higher number, courser grind, faster pour.
Given a correct *[and consistant] dose and tamp, a setting [step] on your grinder either side of the optimun will change the pour length by about 8 or 9 seconds.
If all is good, *as a guide, for a double, *you want, a 60ml pour in about 30 sec *[timed after hitting *the brew switch].
There are some problems with some sunbeam grinders that may also be causing your problems, but until your dose & tamp are, correct and consistant, *you will not be able to determine this.
Let us know how you progress, HANG IN THERE...it takes time.
