Well pretty much what the title says. For a while I have noticed some odd post pour dripping from the group head occurring so decided to clean. Ran the cleaning program and it just stops with pressure needle well into the red which then requires a very gentle and careful release of pressure from the group head. I've already tried pumping through some vinegar and leaving it for an hour and running a cleaning solution from the tank with no change.
Is it possible to open it up and clean out the offending pipe or valve or is there a cleverer solution?
Thx in advance
