Just picked up a Domobar Super HX machine circa 2005.
Have been testing and all functions working, steam, water through group, hot water wand and auto fill. Also machine is reaching 1.5 bar and e61 gets too hit to touch.
Measured flow seems fine 337 mins in 30 seconds.
Problem is testing with portafilter pressure gauge only getting to 4/4.5 bar. Also made a shot but no crema and was super sour.
While testing with pressure gauge I put the the over pressure silicone hose in a jug and there was no water coming out. Also as the case was off checked and not a drop leaking inside. The three way solenoid was releasing into the drip tray once the lever released and seemed to be working fine.
In the morning I will try with a blank filter and see if any water gets sent to the over pressure hose in case my pressure gauge is faulty.
Any ideas on what might be stopping the machine hitting full pressure? Thanks in advance!
