Howard-- I've read all the other responses and I think you've probably solved this by now. However, a subtlety that I noticed in your original post is that you said, "...after a 17-min warmup the temp is stable at 200F and the brew pressure gauge reads 10 bars..."
I don't know if that's what you actually meant, but the brew pressure gauge should read 0 until you try to pull a shot. Then it should climb to whatever you have it set to (I prefer 9 bar with the blind, about 8.5 bar when pulling a shot). When you end the shot, the pressure should once again drop to zero. As an aside, if you are backflushing, after the pressure builds you can lower the handle halfway and the pump will stop, but pressure will remain--useful to keep Cafiza in there for a while before blowing it out by releasing pressure all the way. If it truly is building to 10 bar when you're not pulling a shot, something else is amiss. Also, the first thought I had was "prime"--be sure you are actually moving water through the lines once you get the kink fixed. You may need to use a turkey baster to "feed" water to the supply line and prime the pump. Let us know how it turns out! bmc On Dec 2, 2010, at 7:32 AM, HowardG wrote: > I'm new to this group and my Brewtus III-v was delivered yesterday. > I'm having a real problem with it.
