MODEL-SPECIFIC QUICK ANSWER
De’Longhi La Specialista Touch EC9455M common problems and fixes
The EC9455M uses touchscreen guidance rather than a documented blinking-light fault chart. If Cold Brew follows a hot drink, select the cold recipe and run the dedicated cool rinse; De’Longhi also recommends fresh tank water and 3–4 ice cubes. Follow the display and exact manual for cleaning or descaling.

A NOTE ON THIS GUIDE
Good advice starts with the right manual.
The manufacturer does not document coded fault-light sequences for De’Longhi La Specialista Touch EC9455M. Choose a documented brewing, water-flow, heating, pressure, or maintenance symptom below. Any status indicator shown here appears only when the manufacturer assigns it a specific meaning.
Every troubleshooting path links to manufacturer guidance.
What “verified” means: Each listed signal or symptom is tied to a linked manufacturer source. This is guidance, not a diagnosis of an internal fault.
Coverage: Exact EC9455M identity and support downloads confirmed on De’Longhi pages. The Cold Brew check is from the exact-model FAQ; care steps stay within manufacturer-guided cleaning and descaling.
