For La Specialista EC9355, EC9155, EC9255 and EC9335, check final rinses and completion actions before adding more descaler when the light remains after descaling.
Identify an after-completion warning
Record full model and the manual followed. Failure to start, no water flow, and a remaining light after completion are different support cases.
Use the model-specific final action
De’Longhi’s FAQ calls for a water-only repeat after descaler has acted, with MAX fills for the last two rinses. Those four models also need a final one-click turn towards a coffee drink.
Record the completed stages
Record whether each machine-required stage finished. Do not apply another model’s buttons or dial procedure; use the matching manual and official support.
| Check | Record |
|---|---|
| Model | Confirm EC9355/EC9155/EC9255/EC9335 |
| State | Cannot start / interrupted / light afterwards |
| Final rinses | Each MAX refill and finish |
| Final action | Model-specific drink dial position |
| Outcome | Current light and support question |
Do not improvise a light reset
Check omitted stages against the model procedure. If correctly completed but the light persists, send the stage log to De’Longhi. Avoid hot-water contact and internal disassembly.
A worked example
Hypothetical case: descaling finished but the last rinse tank was filled below MAX. Before repeating with more chemical, check the model FAQ’s water-rinse completion procedure and record the missed stage.
