How to Descale a Nespresso Machine
Nespresso machines (OriginalLine and VertuoLine) build up mineral scale that weakens flow, lowers temperature, and hurts crema. Descaling every three months keeps it pulling well. The button combos differ a bit by model, but the process is the same.
When to Descale
Every 3 months or about every 300 capsules, sooner with hard water. Many models show a descale alert (an orange light or a specific blink pattern).
Enter Descaling Mode
Empty the capsule and drip tray, fill the tank with fresh water and Nespresso descaling solution (or a citric-acid descaler). Most OriginalLine machines: with the machine on, hold both buttons (or the lever-and-button combo per your model) for several seconds until the lights blink in the descaling pattern. VertuoLine: press the button 3 times within 2 seconds to enter descale, per the manual.
Run and Rinse
Place a large container under the outlet and start the cycle — the solution runs through. When the tank empties, refill with plain fresh water and run the rinse cycle (repeat the entry combo) to flush all descaler out. Skipping the rinse leaves an off taste.
Exit and Test
Exit descaling mode (hold the combo again until lights return to normal). Run one more plain-water pass, then brew a test cup. Flow and temperature should be restored.

Nespresso advises against vinegar — it can damage seals and is hard to rinse out. Use Nespresso descaling solution or a citric-acid descaler made for coffee machines.
