Frequently Asked Questions

Why does my DeLonghi coffee taste off?

Off tastes usually come from stale grounds, old water, or residue left in the brew path. 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 Taste Off guide.

My DeLonghi Dedica coffee tastes strange — what could it be?

A DeLonghi brewing weak coffee usually means under-extraction. Grind one step finer, increase the dose slightly, and check that the shot runs 20-30 seconds. If the flow is fast and thin, scale may be limiting pressure — descale, then see our Taste Off guide.

How do I fix bad-tasting coffee from a DeLonghi machine?

Watery coffee from a DeLonghi is a recipe problem more often than a fault: finer grind, more coffee, and a slower brew all strengthen the cup. Thin fast flow also points to scale, so descale first and compare. Full tuning in our Taste Off guide.
