Thanks all. I have had a play tonight and the puck stuck to the shower screen...that is my absolute pet hate!!!!!
Grind probably is a bit fine however if i go any coarser my shot gushes. Very frustrating especially as i was previously happy.
Back to the drawing board. I hate wasting cracking...
I have been fairly happy with how my coffee comes out but there is always room for improvement. For the sake of fiddling, i upgraded the shower screen holder to a brass one (I already have the IMS Shower screen) and I also got a gauge and performed the OPV mod. I also replaced the 58mm burrs in...
