How to descale your coffee machine (Nespresso & Dolce Gusto)

If your machine is running slowly, spluttering, or your coffee has started tasting a little flat or bitter, the culprit is almost always limescale — especially in hard-water areas. Descaling is quick, and it makes a real difference to both taste and the life of your machine.

How often should you descale?

As a rule of thumb, every 2–3 months, or more often in a hard-water area or if you use your machine heavily. Many machines have a warning light that tells you when it's due.

What you'll need

• A descaling solution (or follow your machine's manual — many suggest a specific product)
• Fresh water
• A large container to catch the water
• About 20 minutes

Step by step

1. Empty the machine: remove any used pod and empty the drip tray and water tank.
2. Mix the solution: add descaler to the water tank following the product's ratio, then top up with fresh water.
3. Run it through: place your container under the spout and run the machine (no pod) so the solution flows through. Repeat until the tank is empty.
4. Rinse thoroughly: refill with fresh water only and run at least two full tanks through to flush out any residue — this step matters, or your next coffee will taste of descaler.
5. Reset the descale light if your machine has one (check the manual).

Why it's worth it

Descaling restores water flow and the right brewing temperature, which is what gives you a proper crema and full flavour. Clean machine + fresh, well-roasted coffee = the best cup.
