Descale a Nespresso every three months, or sooner if the red and green lights flash at you at the same time. That blinking pattern is the machine telling you mineral scale - calcium and lime from tap water - has built up inside the heating element and the brew path. Skip it and you get weak shots, a slower pour, and eventually a burned-out boiler.
This walkthrough uses the official Nespresso descaling procedure for the Vertuo Plus, demonstrated by Nespresso themselves on YouTube. The same routine works on every Vertuo model - VertuoLine, Vertuo Pop, Vertuo Next, Evoluo - because the button-and-lever combo is identical across the family. Original Line machines like Pixie, CitiZ, Essenza Mini, and Lattissima follow the same logic with one tweak: most Original Line models only use the espresso and lungo buttons (no lever), and you hold them together for 3 seconds instead.
You need one packet of Nespresso descaling solution, fresh water, and a 1-liter container. The whole cycle runs about 20 minutes once you start it, and it cannot be paused, so plan around it - this is not a thing you do five minutes before guests arrive.
Working through a kitchen-care punch list? Pair this with how to descale a Keurig if you have a pod brewer on the other counter, how to clean a coffee grinder to keep your beans fresh, how to clean a microwave, how to clean a dishwasher, and how to clean a garbage disposal. The whole kitchen runs better when the appliances are clean.
When you need to descale a Nespresso
Three signs it's time:
- The red and green lights flash at the same time. That's the dedicated descaling alert. It triggers after a set number of brews, not on a calendar, so a heavy-use machine hits it sooner than a once-a-week machine.
- The pour is slow or sputtering. A full Vertuo coffee shot should take about 25 seconds. If it drags past 35 seconds or comes out in fits, scale is restricting the brew path.
- It's been three months. Even without symptoms, a quarterly descale keeps the heating element happy. Hard-water areas (well water, the Midwest, the Southwest, anywhere with white residue on faucets) should aim for every two months.
What you need
Nespresso sells its own descaling solution in two-packet sleeves - one packet is one descale, so a sleeve covers six months at the standard cadence. Generic citric-acid descalers work too, but Nespresso voids the warranty if you use straight vinegar (vinegar can damage the aluminum boiler over time), so stick with a coffee-machine descaler if you want to be safe.
