Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Prepare the descaling
- Who:
- you.
- How:
- eject the capsule, close the head with the handle unlocked, put a container of at least 1 litre under the outlet and fill the tank with one unit of Nespresso descaling liquid and 17 fl oz of water.
- Result that matters:
- the machine free of capsules and the tank prepared.
- If a capsule is still inside:
- remove it before going on.
- If everything is ready:
- go on to enter the mode.
- Evidence to keep:
- the reference of the kit used.

What it means
On the Vertuo Next, Nespresso describes the orange and white lights alternately blinking three times before staying on as the descaling alert. Limescale from the water builds up in the circuit and the machine warns it should be removed. The manual says the machine can still be operated when the alert appears, but only a few times before descaling becomes necessary. It is not a fault: the descaling programme solves it.
