Another extraction issues thread :)
Hi guys, having a strange problem with by Silvia and bottomless portafilter.....
I'm getting extraction sweeping from the closest to the machine side of the portafilter towards me....not a circular formation coming together in the middle that I have normally had for the past (ever). Also noting that the furtherest away from the machine part of the portafilter doesn't pour through until 10 seconds into the shot (uneven extraction).
No channelling however, comes together in the centre no probs....but the colour/extraction is defs uneven. Coffee still taste ok, but that's why I'm here......none of us are ok with just "ok" :)
Have changed a lot of variables with no consistent results - no circular formation coming together in the centre.....sweeping from one side of the portafilter to the other.....
Could there be a pressure/mechanical issues with the Silvia?
Will take a vid later tonight to show. Current setup is a Mini-E grinder, with a PID'd Silvia V3. Use an OCD for the redistribution, but have tried WDT and just tapping/setting grinds with no different extraction results.
Thanks for your help or past experiences. :D
