Sticky coffee oils can build up in the chamber. If the inside of the chamber feels sticky when you drag you finger on it, then clean it and the rubber seal with vinegar. After that wipe a bit of vegetable oil on the edge of the seal that contacts the chamber.
- previous post: Help!! I've used my Aeropress for years, with one replacement of the rubber seal. Three months ago I got a new Capresso Infinity grinder which was working just fine, set around the middle of Fine or between Fine and Extra Fine. Things were good. All of a sudden, about a week ago, I can no longer push the plunger all the way down. It stops about 3/4" from the bottom. My husband couldn't even move it. I can push it all the way down only if I use a grind so coarse that the coffee tastes like water. Same coffee, same water, same batch of filters. Pushes out OK when I remove the end cap. I've put in a call to Jura because I think it has to be the grinder – but is there any possibility that it's the Aeropress? Any advice? – From Ellen M.
- next post: Hi. We've been a fan of the aeropress for some time along with good friends of ours. We recently visited them and noticed that their plunger had little ridges on it to help stabilize it when pressing it down. My friend purchased his aeropress years before we did. Our aeropress and a new one he purchased (as a spare) have smooth plungers. Is it possible to purchase the plunger with ridges/grooves any where? Thanks! – From Jennifer L.
