Beyond the fix

Did you knowThe Magnifica S manual says the infuser should be cleaned at least once a month and must never be pulled out while the machine is on. This describes the Magnifica S, so check your own model.

Tips and tricks

  • Leave the infuser to soak for around five minutes, then rinse it under the tap with water alone and slide it back until the two coloured buttons snap out. Source: Magnifica S manual, so check your own model.manufacturer manual
  • If the infuser is hard to refit, the manual says to squeeze its two levers together first to make it smaller.manufacturer manual

Common mistakes

  • Using washing-up liquid or the dishwasher on the infuser. De'Longhi says water only.

Model revisions can differ: if your machine behaves differently, tell us. See our editorial policy.
