Hi
I have an unusual machine - Vibiemme Replica Single Group. It uses standard VBM commercial parts. The group is identical to the Domobar range.
It is in spotless condition and I have recently descaled it. There was virtually no scale - descaling solution was relatively clean after a couple a hours of descaling.
The problem I have is that the machine doesn't exhaust through the 3 way valve at the end of a brew cycle. It maintains the pressure which slowly dissipates through the puck.
When I back-flush, the pressure doesn't get relieved - nothing from the exhaust port.
I've taken the group apart - looks very clean and all the parts appear to be in very good condition. Even the seals look okay.
Any ideas on what could be causing this? Happy to replace parts where required, but no obvious reason why it doesn't work. The exhaust port is opened manually when the brew cycle completes, so I don't understand why it doesn't release the pressure.
I've attached a few pictures of the machine.
Cheers, David
