prezes You can’t do it with a blind filter….won’t work as expected. It needs to be with coffee.
To prevent an overshoot with a blind filter you would have to have the system cut down so aggressively as it closes on the set point, it wouldn’t work properly at all with coffee. Reset it back to the original settings apart from pump acc, and do it with coffee.
The reason is that with a blind filter, you create a sealed system (one way valves and all that), once the pressure goes over, the pump can pretty much stop, but the pressure can’t reduce. it can’t work properly with that restriction.
