Mine (Coffee Deluxe) drips all the time from the PF spout when switched on, but it hasn’t affected the crema. Have you taken out the shower screen (remove PF and undo the single philips head screw to get this out), and pricked all the holes clear with a pin? If some/many of these are blocked the espresso will come out flat as ink.
Also check for clumping from your grinder. Grind a full basket into the PF, level it off, then stir up the grounds with a long needle to break up any clumps.
Then tamp and see if it’s any better.
The bottomless filter as mentioned above is a great addition, much easier to keep clean, but the distribution of the grounds is crucial otherwise you end up with coffee spurting all over the kitchen.
Blind filters for cleaning are no good with machines without 3 way valves to let the pressure back out, which I guess yours won’t have.
