Error Codes
DeLonghi Dedica error lights: what does each light mean?
Error codes on DeLonghi machines usually point to a specific condition: a full drip tray, an empty water tank, a stuck brew unit, or scale buildup. The most common codes are listed in our error code flashing guide — most are cleared by a power reset or a descaling cycle.
DeLonghi coffee machine error codes — most common ones
Error codes on DeLonghi machines usually point to a specific condition: a full drip tray, an empty water tank, a stuck brew unit, or scale buildup. The most common codes are listed in our error code flashing guide — most are cleared by a power reset or a descaling cycle.
Descaling & Maintenance
DeLonghi Dedica descaling not working — how to fix
Scale builds up inside every coffee machine and eventually blocks the boiler and pipes. Run a full descaling cycle with DeLonghi's approved descalant every 2-3 months (or whenever the machine prompts it), then rinse with fresh water. If your machine refuses to descale, see our not heating guide.
Grinder Problems
DeLonghi coffee machine grinder not working
A DeLonghi grinder that stops usually has beans jammed in the burrs, an empty-hopper sensor triggered, or worn burrs. Empty and brush the hopper, run a few dry beans through, and never force the motor. Detailed steps in our grinder not working guide.
Water Flow & Pumping
DeLonghi coffee machine water not working
If no water comes out of your DeLonghi machine, the tank may be mis-seated, there may be air in the circuit, or the pump inlet is blocked by scale. Reseat the tank, run a blank cycle to purge air, and descale if flow stays weak. See our water not pumping guide.
Coffee Quality

Weak or watery coffee from a DeLonghi machine is almost always grind, dose, or extraction time: grind finer, use a correct dose, and make sure the brew lasts 20-30 seconds. Scale can also slow extraction — descale if the flow looks thin. See our not brewing guide.
Water Leaks
DeLonghi Magnifica leaking water — common causes
Water leaking from a DeLonghi machine is usually a loose hose, a worn seal, or a drip tray that is not seated correctly. Dry the machine and trace where the water appears during a brew cycle — most leaks are repairable without a service visit. Full steps in our leaking water guide.
Power & Startup
DeLonghi coffee machine not turning on
When a DeLonghi machine won't turn on, check the outlet, the power cord, and the switch first. Unplug it for 60 seconds and retry — this clears most temporary control-board faults. If it stays dead, the thermal fuse or power supply may need replacing; see our not turning on guide.
