Jura Lower Piston Pops Out Won’t Cycle

Also, BE SURE you have your bushings in place! Absent the bushings, the gearbox can go up a couple millimeters too high and bam, out pops your piston.

hello there, wanted to enquire if the "cylinder" you're mentioning here is the water inlet into the brewer? thanks!

[@mguerramd]

Yes it is. That little cylinder on the bottom of the lower piston conducts water from the nipple on the drainage valve in to the brewing chamber.
