Breville barista pro not pulling shots
I have a Breville barista pro, have had it for about a year now. Last 2 weeks, it stopped pulling shots. Same coffee beans I been using for 2-3 months, same grinder setting. Sometimes it works, specially during programing, but then when I try to pull a shot again it doesn't work
I tried the following already.
Increased the grind setting, even by 5 and sometimes it just gets me 36g in like 10 seconds, obviously since the grind is to corase, but sometimes even with that higher setting it doesn't pull a shot.
Water comes out when I try without any coffee.
I am not using the double wall filter, do the hole is not blocked. Even the double wall one, I have 2 difference kinds and used both, still same issue.
I think it might still be under warranty, has anyone dealt with their technical issues department before?
