Help to fine tune a Wega Mininova
· It now produces coffee through a finer grind then when I first got it running (not as fine as the em6910) Now it seems that the 2nd opv leaks quite a bit. I have tightened the opv completely but still leaks a lot under pressure. (Can you get new internal components for these opv's or do i just need to buy a new one?) With regards to steam.
