Hi all, really hoping you guys might be able to help!

I've had my oracle for a around 3 months and had pretty consistent results from it once I learnt how to dial in beans. Yesterday though, it appears to have stopped dosing and tamping properly after giving it a brush down as I do every Saturday.

It sounds like it just doesn't stop grinding where it should, and then the fan seems to get stuck in the grounds from the imprint. There's about 34g in the basket and loads more up inside the machine:

Any ideas what could be causing this, and if it's likely to be my error or something wrong with the machine? I'm using the provided double basket. I've taken the tamping fan out and cleaned it etc and nothin looks obviously wrong!

Thanks in advance guys
