I have since bumped my machine up to 1.2..... coffee isnt burning.
Im yet to pull the blend I was originally having trouble with though.
There will be an increase in temperature at the group head as higher pressure = higher boiler temp and therefore the water in the HX will also be hotter. This machine ships at 1.0 bar for good reason Have you thermologged it?
Update: the machine is now up to around 1.5... the depth of flavours coming out in the coffee is the best Ive seen to date. Sourness seems to have been eliminated now too, so Im going to give Campos Superior Blend, etc. a crack and see how they go.
My Faema Due was set up for a busy commercial setting, even though it was not in one....and the steam pressure was always sitting well over 1.2 bar - the steam that came out of the 4 hole tip was totally insane. The pump pressure was also set high, so that with both groups running and the auto fill cutting in there was still about 9 bar, but stick in a blind and the thing would charge up to 11-12 bar!
Long cooling flushes had to be used - in a busy cafe it wouldnt ahve been a problem probably. With the help of the guys here I tuned in down to a more managable home level - it now runs at about .7bar - .95 bar. And for the pump in the middle of the 9 bar part of the guage. Before tweaking my wife would sometimes forget to flush and the coffee was burnt and bitter because of it. Now the coffees are consistently great.
The steam power I had started to get used to, but it was very unforgiving - now its much easier to use and creates lovely thick micro-foam, but concentration is still required and the volume is still very high.
Just some thoughts for you....dont know if they assist.
