Just recently, with the same grind/dose/tamp using the same batch of beans, I have randomly been experiencing occasional gushers and also choked pours.
Maybe 1 in 15-20 shots.
I am fairly confident it is machine/grinder related and not a usage issue.
My guess at potential problems are:
1) Pump on the way out (doesn't sound any different)
2) Worn grinder burrs
3) OPV playing up
Before I start replacing parts I thought I would check if any of these are more likely or if it could be something else.
I have an Iberital De Recanvis which has ground about 400g per week over the last 7 years for me.
However I bought it from a Coffee Snob and don't have any information about its previous history.
Quaha single boiler, likewise I've had for 7 years but don't know the history of.
Thanks
