Went to this machine as customer complained was overfilling/ not draining quick enough etc.
As I thought the pressure vessel was very blocked, after cleaning the pressure vessel the machine now takes only about half a cm of visable water and boiles the water in a few minuites when element comes on.
Have cleared out chamber pretty thoroughly now but still will not take any more water.,
Some of the older Miele models go into a default mode once the air bell is blocked. Only way to re-set is a new control pcb or a Miele man and his laptop. Dont think this is one of these though.
