Using the Aroma Button on Your De’Longhi Coffee Maker
The Aroma button on your De’Longhi coffee maker is a brew-strength toggle that slows water flow through the coffee grounds for a stronger, more concentrated cup. Press it once before starting the brew cycle, and a small indicator light confirms strong mode is active. The button only works during brewing — it’s not a scheduled or pre-programmable setting, and it doesn’t change grind size, water temperature, or brew time.
One important boundary up front: the Aroma button appears on De’Longhi drip coffee makers, not on the automatic espresso lines. If you own a Magnifica, Dinamica, or other bean-to-cup model, you won’t find this button — you’ll use an “Intensity” or “Strength” setting in the menu instead. Knowing which category your machine falls into saves you from hunting for a button that doesn’t exist on your model.
What the Aroma Button Changes (and What It Doesn’t)
The Aroma button works by altering the water-to-coffee ratio during extraction. When active, the machine restricts water flow through the grounds, extending contact time and pulling more soluble compounds from the coffee. The result is a fuller-bodied cup with more pronounced bitterness.
What it does not do:
- Change grind size — The burrs or blade settings stay exactly where you set them.
- Alter water temperature — Extraction happens at the same heat regardless of mode.
- Adjust brew time on a timer — You can’t schedule a strong brew for tomorrow morning; the button only affects the cycle you start manually.
- Require a different coffee dose — Use the same amount of grounds you normally would.
The practical implication: if your coffee tastes weak because your grind is too coarse or your dose is too low, the Aroma button won’t fix it. It only intensifies extraction from the coffee you’ve already loaded. If you’re chasing a stronger cup, the button helps — but it’s one variable among several.
How to Use the Aroma Button: Step-by-Step
Step 1: Prepare the machine normally.
Fill the reservoir, add ground coffee to the filter basket, and place the carafe on the warming plate. Use your standard dose — don’t add extra coffee just because you’re using strong mode.
Step 2: Press the Aroma button before starting the brew.
A quick, single press is all it takes. The indicator light next to the label should illuminate. If the clock display starts blinking instead, you’ve held the button too long — that’s the clock-setting mode on some models. Press it once, quickly, and the display should return to normal.
Step 3: Start the brew cycle.
Hit the brew/start button as you normally would. The machine will run the cycle with the reduced water flow.
Step 4: Confirm the light stays on.
The indicator should remain lit for the entire cycle. If it turns off on its own, the machine has reverted to standard mode — press the button again within the first 30 seconds of the cycle to re-engage it.
Step 5: Taste and adjust.
The first cup tells you whether strong mode suits your preference. Too bitter? Switch back to standard next time. Still not strong enough? Your next move is adjusting the dose or grind, not the button.
When the Aroma Button Won’t Work
Several scenarios can leave you pressing a button that seems dead. Here’s how to diagnose each one:
Your model doesn’t have an Aroma button.
If your machine has a menu screen instead of physical buttons, look for “Intensity” or “Strength” in the settings. On the De’Longhi Magnifica Evo Automatic Espresso Machine, strength is adjusted through the menu system with multiple levels, not a single on/off toggle. The De’Longhi Magnifica Start Automatic Espresso Machine works the same way — you’ll navigate to the intensity setting rather than pressing a dedicated button.
The button only works during an active brew cycle.
On some models, pressing the Aroma button while the machine is idle does nothing. Start the brew first, then press the button within the first 30 seconds. If the light comes on, you’re set.
The button changes the clock instead of brew strength.
This happens when you hold the button too long. A quick tap toggles strength; a 3–5 second hold enters clock-setting mode. If the time display is blinking, you’ve triggered the wrong function. Press the button once, quickly, to exit clock mode, then tap it again to activate strong brewing.
The light is on, but the coffee tastes the same.
This is the most common complaint, and it usually comes down to one of two causes. First, if your grind is very fine, the water is already flowing slowly — the Aroma button’s restriction has little additional effect. Second, if you’re using a dark roast, the flavor difference between standard and strong mode is harder to detect because dark roasts already produce bold, bitter cups. Try a coarser grind or a lighter roast to make the button’s effect more noticeable.
Aroma Button vs. Manual Strength Adjustments
If your De’Longhi doesn’t have an Aroma button, or if you want more control than a simple on/off toggle, you have two alternatives:
Adjust the coffee dose.
Increasing from 1 tablespoon per 6 ounces to 1.5 tablespoons per 6 ounces produces a stronger cup without changing water flow. This is the most reliable method because it doesn’t depend on the machine’s flow mechanics. It also gives you fine-grained control — you can dial in exactly the strength you want rather than choosing between two preset modes.
Use the menu-based intensity setting.
On automatic models, the intensity setting adjusts both water volume and brew time across multiple levels. This is more precise than the Aroma button because you get 3–5 strength options rather than a binary choice.
The trade-off: the Aroma button is faster and requires no measuring. The manual methods give you more control but require trial and error. If you’re the kind of person who wants the same cup every morning with minimal fuss, the button is the better choice. If you’re chasing a specific flavor profile, dose adjustment wins.
Cleaning After Strong Mode
Running the Aroma button doesn’t require special cleaning, but strong mode extracts more coffee solids into the carafe, which means more residue in the brew basket and on the warming plate over time.
After each use: Rinse the carafe and filter basket with warm water. Don’t let wet grounds sit in the basket for more than an hour — they’ll leave a sticky film that’s harder to remove later.
Weekly: Run a cleaning cycle with a descaling solution. For drip machines, a vinegar-and-water solution (1:3 ratio) works fine. Run it through with the Aroma button off — you want standard flow to flush the system thoroughly. For automatic models with milk-frothing circuits, the De’Longhi Universal Espresso Machine Cleaner is formulated for that specific cleaning path.
Monthly: Remove the filter basket and inspect for coffee-oil buildup. If you see a slick film, wash with mild dish soap and a soft brush. Avoid abrasive scrubbers — they can scratch the basket, and scratches create uneven extraction channels that affect flavor.
How to Verify the Aroma Button Is Working
After pressing the button and starting a brew, check two things:
1. The indicator light stays on throughout the cycle. If it turns off on its own, the machine has reverted to standard mode.
2. The brew time is noticeably longer. On most De’Longhi drip models, a full carafe takes 8–10 minutes in standard mode and 10–13 minutes in strong mode. If your brew finishes in the same time as usual, the button didn’t engage.
The taste test is the final check. Strong mode should produce a cup with more body and a slightly more pronounced bitterness. If you can’t tell the difference, brew two cups side by side — one with the button on, one with it off — using the same coffee and dose. The contrast will be clearer than relying on memory.
If the button still seems non-functional after checking all of these, consult your model’s manual or contact De’Longhi support. The button is a simple switch, and if it’s not engaging, it’s likely a hardware issue that requires service rather than a setting you can fix at home.
