Hi all,
I am having a problem with my portafilter leaking during a shot with the Silvia. The water is clear and leaks from the outside of the portafilter.
I initially thought that the gasket could be worn so replaced it but still got leakage so I went back to using the stock Silvia portafilter and basket with 14g and had no leakage. On reflection I think it started to happen when I dosed down to 14g with a new blend in a Synesso Double ridgeless basket.
I had been using the Synesso Double with my bottomless (http://www.happydonkey.co.uk/rancilio-b ... p2902.html) very happily for around a week with another blend at 19-21g without any leakage and had used the bottomless with a generic ridged triple for years without issue. So today I went back to a higher dose with the Synesso basket and leakage appeared reduced, I'm going to try again tomorrow and will try to fit the portafilter in a little tighter to see if the problem has gone with a higher dosage.
I really don't want to ruin any more shots but would like to use the Synesso basket so would appreciate it if somebody could shed some light on this. I've not tried my old triple ridged basket yet but imagine it will work fine.
Could underdosing or using a ridgless vs ridged basket cause the portafilter to sit less snug with the gasket during a shot and therefore cause leakage?
Have any other Silvia owners experienced similar issues with the Synesso Double?
Thank you
