Hi All, I just finished all maintenance on my recently bought Cimbali Junior D.
Because the pump (Cimbali 533-197-400) looked old and a bit rusty I changed it for a new one.
I found by a local dealer an Ulka pump type CS M3886. As I was told should be good enough for my Cimbali. First I tried the machine with the old pump, pressing coffee the normal way and had no problems making a good espresso. Since I installed the new one, I cannot press the coffee at all and it takes much longer to make a ristretto.
I suspect the new pump has no power enough!
Is there any of you who could enlighten me on this matter? Thanks in advance.
