Demoka M203 fix or upgrade to (almost) zero retention

A week ago I got my hand on a Demoka M203 along with the La Pavoni Pro PRG. As I did with all second hand stuff I get, I served an nice clean-up. After removing the neck/funnel, there was quite some coffee clogged up between the burr's and the neck. So I was wondering if there are some fixes or upgrades for the neck or a special cover for the beans cabinet to blow-out the retention coffee (like the Turin DF64)?
