dfk41 Thanks Dave ( and @mathof2)
I didn’t stay with the stock basket for long and latterly used an E&B Lab superfine 16/18 gm.
Since they launched, I’ve always used a Push tamper, which works for me (helps me manage another variable).
Ah, seals. I changed them about six months before the safety valve and pressure switch stopped doing what they should have been doing. Do you think that I should still change them? (I’m waiting for the weekend to fire up the machine - work keeps getting in the way).
Thank you again.
