Rinse the jet and seal
DailyThe injection jet is a narrow hole, and a blocked one changes the brew completely.
What you need
- Hot water. Washing-up liquid weekly. Nothing abrasive.
What goes wrong
- Storing it with the plunger pushed in, which flattens the seal over time. Poking the jet with wire, which widens it and permanently changes the flow rate.
The procedure
- Eject the puck immediately and rinse the filter cap under hot water.
