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.
Sensor check
What they doThe De'Longhi service technician finds which sensor fails and checks its connection, comparing its reading with a reference instrument.
They must show youthe failing sensor and its reading against the reference.
In writingthe part replaced, its reference and the reason.
Test within the limits
What they doAfter the repair, the technician runs the unit in conditions within the limits and confirms neither E2 nor E3 appears.
They must show youthe unit running without a code and the test conditions.
In writingthe test and its result.
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.

What it means
On the DD230P, De'Longhi explains that E2 or E3 appears when one of the appliance's sensors is faulty or when room humidity is too low or too high to be measured correctly. Its operating limits are 5 °C to 32 °C and 30 to 90 % humidity. The fix is to see whether it works again in another room within those limits and, if not, call service. On the DEXD216F, De'Longhi attributes E1, E2 and E3 to a faulty probe. The code alone does not tell whether a sensor fails or it is the room.
Warnings and stop conditions
- Loweditorial warning
Do not open the unit to check the sensors: De'Longhi says to call service if the code persists.

Symptoms and causes
Probable causes · in order
- Humidity outside the measuring range (DD230P)Possible
If E2 or E3 clears after moving to a room within the limits, the cause was room humidity, not a sensor.
Evidence: De'Longhi Tasciugo AriaDry DD230P instructions for use
- Faulty sensorPossible
If the code stays in conditions within the limits, De'Longhi attributes it to a sensor; on the DEXD216F it is the only cause given.
