Breville Barista Express grind time is off


A couple weeks ago, the grind time on my Barista Express is way too short. In settings where I normally got around 15-20g I now get less than 10g. Now to get what is close to a normal dose I have to max out the grind amount dial.

I tried cleaning the grinder and even replacing the top burr assembly and the problem was not fixed.

It really seems like the grind time has shortened… Is there any way to adjust the grind time with this machine?

Thank you
