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.
Probe check
What they doThe De'Longhi service technician checks the humidity probe and its connection and compares its reading with a reference instrument.
They must show youthe probe reading against the reference instrument.
In writingthe part replaced, its reference and the reason.
Operating test after the repair
What they doThe technician runs the unit in conditions within the limits and confirms E1 does not appear.
They must show youthe unit running without E1 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.

Test in another room
- Who:
- you.
- How:

What it means
In the alarm table of the DDSX220 and DDSX225, De'Longhi gives two causes for E1: room humidity too low or too high to be measured correctly, or a faulty probe. The operating limits are 2 °C to 30 °C and 30 to 90 % relative humidity. If the problem stays after moving the unit to another room within those limits, call the Service Centre. On the DEXD216F, E1, E2 or E3 are attributed to a faulty probe. The code alone does not tell which cause it is, which is why the room change test comes first on the DDSX models.
Warnings and stop conditions
- Loweditorial warning
Do not open the unit to clean or move the probe: De'Longhi says to call the Service Centre if E1 persists.

Symptoms and causes
Probable causes · in order
- Humidity outside the measuring range (DDSX220, DDSX225)Possible
If the room is below 30 % or above 90 % humidity, E1 clears when the unit is moved to a room within the limits.
Evidence: De'Longhi Tasciugo AriaDry Multi DDSX225 instructions for use
- Faulty probePossible
If E1 stays within the limits, De'Longhi attributes it to the probe; on the DEXD216F it is the only cause given.
