I pulled out the 3 way valve and forgot to note which way the spring sits in the cup. Does the spring sit in the cup/nut first or does the rubber seal?
I pulled it out to check it as the machine seems to surge during a pour where the dial goes from about 2 oclock back to 12 oclock and then keeps bouncing between the 2 with the noise varying as well.
I took it in to get checked by the service agent but they didnt find anything wrong with it using there test basket in the porta filter.
