I've been using my Brewtus I (which of course I bought used) for over a year, but I'm a first-time poster to this forum.
Recently I've come to think that the OPV on my machine needs to be replaced. I'll describe how I came to this diagnosis and I'd like to hear if people think I'm correct or not. (1) After over a year of pulling espresso and getting very consistent at it, I suddenly started having every shot come out too quickly. No matter how much finer I adjusted the grind, it would start coming out at around 5 seconds (instead of eight), and the coffee would pour out with no tiger striping, with gushers, etc., and it was blonding completely at around 15 seconds. Also tasted horrible. At first I thought the problem was my grinder. Baratza actually sent me a refurbished grinder (Vario) after discussing it over the phone. But nothing changed with the new grinder. (2) I called WLL technical support and discussed the problem. They said it was most likely the OPV either needed to be adjusted or replaced. They also sent me some diagrams. (3) I opened the machine to adjust the OPV for less pressure. I turned the nylon adjustment screw less than 1/4 turn counterclockwise and tried another shot to see if there would be any noticeable difference. But then after my next shot I saw a trickle of water coming from the machine. I looked more closely and saw water collecting on top of the nylon screw and then trickling down from there. This seemed to confirm to me that the OPV is having a problem, like WLL thought. Does that sound like the correct diagnosis? Or is there anything else I should try to be sure?
