Hey Folks,
My title could be a little off. Basically my machine is a few years old now and i think some sediment or build up is stuck in the machine. When i run it normally fires all the way up to around 8 bar then it sounds like the whole machine goes quiet. So for example, a coffee is run through the machine, it will run all the way upto around 7-8 bar and then it basically stops running, the pressure starts to drop, it goes down to around 5-6 bar and then starts running again.
I'm just guessing, but could be the OPV is a bit blocked or perhaps something in the group maybe blocked ? Just the fact its running upto around 7-8 bar then starts to drop off makes me look in that area.
Any suggestions of ideas. My machine is well past warranty and got no dramas opening it up to clean some bits out.
Thanks in advance
