simonc It’s a 20g VST basket. Not used it for 6 months as been on my 16g basket.
Any ideas?
Longshot: are you using a bottomless PF? Does the 20g basket have straight sides? Is the inside of your PF tapered (get narrower towards the bottom?).
I once had a similar drip issue because the bottom of a straight-walled basket hit the sides of a tapered PF so the basked wasn’t seated completely in the PF (if I pressed one side of the basket into the PF, the other side would move up, like a seesaw, see video below). It almost fitted, so it took me a while to notice that this was the issue. Because you said it happened when you moved from a 16g to a 20g basket, I thought you might have a similar issue.
