De’Longhi Dinamica ECAM35020: what the lights mean
Bean-to-cup with a touch panel of symbol lights (Dinamica ECAM35020B, US manual)
The Dinamica (ECAM35020B in the US) is a step up from the Magnifica S: instead of a row of buttons it has a flat touch panel, but its warnings work the same way — a symbol for the grounds container, one for the water tank, one for descaling and a heating light, each meaning one thing when steady and another when flashing. The manual draws each symbol as a picture, so this page names each one by the job the manual gives it in ‘2.2 Description of the touch screen’; in the quotes, [symbol] marks where the manual shows the picture. The ‘Explanation of lights’ table also lists alarms shown by combinations of symbols (beans run out, grinding too fine, too much coffee) without naming the symbols in words; those are left out here rather than guessed at.
Every De’Longhi Dinamica ECAM35020 light we could source, 9 in all, each with De’Longhi’s meaning and steps. This is the Dinamica ECAM35020’s pattern; another De’Longhi machine may use the same light for something else — check the manual for your model.
Heating light flashing on the touch panel
Heating up
The machine is heating up and running its rinse: hot water circulates and a little comes out of the coffee spouts. The same light flashes while it rinses before switching off. If it flashes when you ask for a coffee, De’Longhi says the machine has detected impurities in its internal circuits.
“To turn the machine on, press the [symbol] button (A23) (fig. 7). The [symbol] light (B1) flashes on the touch screen (B) to indicate the machine is heating up.”
- Which light
- Icon on the display screen
- Colour
- Colour not named by the maker
- Steady or flashing
- Flashing or blinking
What De’Longhi says to do
- Wait: the machine is ready when this light goes off and the coffee icons come on.
- If it flashes when you choose a drink, wait for the machine to be ready again and choose the drink again. Contact Customer Services if the problem persists.
If that does not fix it: how to contact De’Longhi.

Grounds container light flashing
Container or tray
The grounds container is full and must be emptied and cleaned. The machine makes no coffee until you do. It also asks 72 hours after the first coffee, even if the container is not full.

Descale light flashing, with only OK and ESC lit
Descale needed
The machine needs descaling. How soon it asks depends on the water hardness setting (level 4 out of the box). If you press ESC, the light keeps flashing as a reminder.
“Descale the machine when the [symbol] light (B5) on the touch screen (B) flashes and only the OK (B15) and ESC icons (B14) remain on. To descale immediately, press OK and follow the instructions from point 4. To descale the machine later, press ESC.”
- Which light
- Descale light or symbol
- Colour
- Colour not named by the maker
- Steady or flashing
- Flashing or blinking
What De’Longhi says to do
- Press OK to descale now, or ESC to do it later.
- Empty the drip tray and grounds container; empty the water tank and take out the water softener filter if fitted. Pour De’Longhi descaler to level A (a 100 ml pack), add a litre of water to level B and refit the tank.
- Put a container of at least 1.8 litres under the frother and the coffee spouts and press OK. When ESC flashes, turn the steam/hot water dial to I. After about 35 minutes the water tank light flashes: rinse twice with a full tank of fresh water as the manual’s section 18 describes, then turn the dial back to 0.
- Use De’Longhi descaler only; De’Longhi says unsuitable descaler or incorrect descaling may cause faults not covered by the guarantee.
