Stuck pucks can be solved by a puck screen. In fact, the other day I forgot to add the puck screen, removed the PF and found the basket and the puck stuck to the screen. The basket was stuck with the puck only because the spring is not very tight. For me, a puck screen solved the problem. With another basket I have, only the puck gets stuck, the basket stays with the PF.
Now, a stuck basket… The only time I got that without any coffee in it was if the gasket, or shower screen, or basket were wet before leaving the PF to warm up with the machine.
