What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Check of the infuser housing
What they doDe'Longhi service checks the housing, the mechanism that moves the infuser and the detection that it is in place.
They must show youthe infuser detected and the machine completing a coffee.
In writingthe cause found and any part replaced, with its reference.
Shutdown and removal test
What they doThe technician switches off with the button, removes and refits the infuser and makes a coffee with no message.
They must show youthe infuser coming out and going in, and the coffee made.
In writingthe test carried out and the date.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Infuser in and locked
- Who:
- you, no tools.
- How:
- open the service door and see whether the infuser is inside; if not, fit it and press the PUSH button until you hear a click, as De'Longhi says.
- Result that matters:
- the infuser locked in and the door closed.
- If the message goes:
- it only needed refitting.
- If it will not go in or the message stays:
- go to the shutdown cycle.
- Evidence to keep:
- a photo of the fitted infuser.

Full start-up and shutdown cycle
- Who:
- you.
- How:
- switch the machine on and wait for the full start-up; switch it off with the power button and wait for the shutdown to finish; only then unplug if needed, and try fitting the infuser.
- Result that matters:
- the mechanism back in position and the infuser going in.
- If it clicks in and the message goes:
- the problem was the shutdown.
- If it still will not go in:
- do not force it; contact De'Longhi support.
- Evidence to keep:
- a note of how the machine had been switched off before.

Correct infuser cleaning
- Who:
- you.
- How:
- at the next cleaning, soak the infuser in lukewarm water for about 5 minutes, rinse with water only and a brush, no detergent, and refit it with PUSH; De'Longhi asks for this at least monthly.
- Result that matters:
- a clean infuser that fits first time.
- If it fits and the warning does not return:
- maintenance is right.
- If it is hard to fit even when clean:
- tell De'Longhi support.
- Evidence to keep:
- the date of each cleaning.

What it means
De'Longhi explains the message appears when the infuser has not been replaced after cleaning. The infuser is the removable unit where coffee is pressed and hot water passes; without it the machine cannot brew. According to De'Longhi, if the infuser will not come out or go back in, it is usually due to an improper shutdown: switch off with the button and let the cycle finish before unplugging. The message does not prove the infuser is broken; refitting it correctly is almost always enough.
