🔧 Owner's Guides · 2026Weak coffee, coffee that is not hot, a grinder that will not grind or has gone noisy — the causes and the fixes from De'Longhi's own support pages.
Written and reviewed by the CoffeeLabAdvisor editorial team · Published 29 September 2026
Four complaints cover most of it, and three have the same cause. Coffee not hot enough is usually the circuits cooling: if two to three minutes have passed since the last cup, hold the rinse button to warm them before brewing. Weak coffee means the grind is too coarse — turn the grinding adjustment one click towards “1”, and only while the grinder is actually running. Coffee delivered too slowly is the same dial the other way. And a grinder that has gone noisy and stopped grinding usually has something in it that is not a coffee bean.
This is the most common complaint about any bean-to-cup machine and it is usually not a fault. De'Longhi's own answer: if two to three minutes have elapsed since the last coffee, the internal circuits have cooled down. Press and hold the rinse button for a few seconds to run a rinse cycle and warm the circuits, then brew.
Two things make this worse and are worth ruling out before you conclude the machine is broken. A cold cup takes a surprising amount of heat out of a small drink — warm it with the rinse water rather than throwing that away. And milk added from the fridge to an espresso will drop the temperature of the finished drink far more than anything the machine is doing.
If the coffee is still not hot after a rinse on a warmed cup, look at scale next: it insulates the heating circuit, and the descale cycle is the fix.
De'Longhi's answer is the grind. If the coffee is ground too coarsely, water runs through the puck without taking much with it, and the cup is thin. The fix is to turn the grinding adjustment knob one click anticlockwise, towards “1”, and then to keep going one click at a time until the cup is right.
Two details in that instruction do the work, and both are easy to miss:
The same dial, the other direction. If the coffee was ground too fine the water cannot push through the grounds, so delivery slows to a drip. Adjust the grinder towards a coarser setting — again while it is running, again judged over two coffees.
If the grind is not the cause, the next suspect is scale narrowing the circuit rather than the puck resisting it. A machine that has slowed gradually over months, on a setting that used to be fine, is usually asking to be descaled.
De'Longhi's guidance is that there may be a foreign object among the coffee beans in the grinder — a stone, a piece of packaging, something that came in with the bag. The sequence:
If nothing is visible and it still will not grind, the machine may simply be in the wrong mode: the coffee quantity dial has a pre-ground setting that bypasses the grinder entirely and is used for tamping only. A grinder that is silent rather than noisy is more likely this than a fault.
One piece of De'Longhi's advice is preventative rather than a fix, and it explains a lot of repeat grinder trouble: avoid oily, caramelised or coated coffee beans, because they stick inside the grinder.
This rules out more of the supermarket shelf than people expect. Very dark roasts carry visible oil, and flavoured beans are coated by definition. Neither is a bad coffee — they are just a poor match for a machine that grinds on demand into a sealed chute. If you like dark roasts, clean the burr chamber more often rather than changing what you drink. Our bean guide covers the choice, and how to store beans covers keeping them dry.
Everything above is adjustment and cleaning. Some things are not. A machine that will not brew at all and is showing flashing alarm icons is reporting a fault rather than a preference, and De'Longhi's help centre has model-specific pages for those — you will need your exact model code, which is on the sticker underneath or behind the drip tray.
Before concluding a machine is finished, though, run the descale cycle. Scale accounts for a surprising share of machines that stopped working properly, it is cheap to rule out, and the procedure is here.

De'Longhi says that if two to three minutes have passed since the last coffee, hold the rinse button for a few seconds to run a rinse and warm them before brewing. A cold cup and fridge-cold milk take out more heat than most people expect.
The grind is too coarse. Turn the grinding adjustment one click anticlockwise towards “1” while the grinder is running, and judge the result after two coffees rather than one — there is already ground coffee in the machine at the old setting.
De'Longhi's answer is a foreign object among the beans. Turn the machine off and unplug it, vacuum out all the beans so you can see in, and remove the obstruction gently — do not force it if it is stuck.
No. De'Longhi says to set the grinder only when the machine is actively grinding beans. Turning the adjustment against stationary burrs is a common way to jam them.
De'Longhi advises against oily, caramelised or coated beans, because they stick inside the grinder. That covers most flavoured coffees and the oiliest dark roasts.
