bubbles on the coffee

[flo]

hi,

since a few days, when i pour a coffee, i get the same crema as usual, but with a lot of bubbles. i use a rancilio system s20 de 2 groups.

has anyone experienced that before ??

thanks in advance.

sounds like we both have the same problem with the same machine.
all i did was adjust the pressure on my external pump, i know it isnt exactly what youre suppose to do, but it helped.

Has anything changed, the coffee supplier, or have you have the machine serviced
