What goes wrong

Standard AeroPress papers do not fit or seal. The usual press speed is too fast for the bigger bed and channels. Leaning your weight on a stiff press forces fines through: harsh.

Care schedule

1 task for this machine.

Replace the plunger seal

Yearly

The rubber seal is the only thing making an AeroPress a pressure brewer. Once it hardens the plunger slides too easily, air escapes past it, and the brew goes weak and thin with no obvious cause.

What you need

A replacement seal for your model - the XL seal is not the standard one. Warm soapy water.

What goes wrong

Storing it compressed, which flattens the seal within months. Diagnosing weak coffee as a grind problem when the seal is passing air. Buying the wrong model's seal. Putting oil or grease on the rubber, which swells it.

The procedure

Test the old one first. Seal the chamber with the filter cap and no filter, insert the plunger 2cm, and press. It should resist. If it slides freely, the seal is done.
