OK, thanks to both of you. So I did short it out, just long enough to bring the machine up to pressure and pull a shot and try backflushing. Everything works great, so I think I will just order a couple of those and I should be in business.
Not able to solve the spring mystery, looked at several exploded parts diagrams on the web and dont see anything like it. Maybe it's from somewhere else. My next challenge is adjusting pump pressure. I'm getting about 8 bars with a blind portfilter, so I guess it needs just a little tightening. I can reach the screw by coming in underneath and from the other side with a screw driver. But I cannot figure out how to loosen the lock nut. It is too close to the main water pipe to get a wrench on it. Can I just detach the the pump from the case and move it a bit until I get pressure adjusted and then screw it back? Doesn't seem too dangerous, as long as I unplug when I'm actually touching things. Any ideas on how much of a turn is likely to get me from 8 to 9 bars, just to speed up the trial and error approach? thanks, ~Bill On Wednesday, February 15, 2017 at 6:41:26 PM UTC-6, bmacpiper wrote: > > Agreed with Herman.
