Nespresso Lattissima One: what the lights mean

Original line with a one-serve milk jug (Lattissima One EN 500)

The Lattissima One takes the same small Original capsules as the Citiz, Inissia and Pixie, but adds a milk jug that froths one serving at a time. Its panel has three buttons (Espresso, Lungo and the milk button) plus two small alerts marked DESCALING and CLEAN that light orange. Most of what the panel says comes from the three buttons blinking together, steadily, fast, or in turn, and the manual’s troubleshooting table (p. 28) is the key to telling those apart. Every pattern below is quoted from that manual.

Every Nespresso Lattissima One light we could source, 12 in all, each with Nespresso’s meaning and steps. This is the Lattissima One’s pattern; another Nespresso machine may use the same light for something else — check the manual for your model.

All three buttons blinking after you switch it on

Heating up

Several lights or symbols at once: flashing or blinking

The machine is heating up, which takes about 25 seconds. The buttons blink the same way, for about 15 seconds, when you connect the milk jug for a milk drink.

“Switch the machine on by pressing any of the three buttons: - Blinking lights: heating-up (25 sec) - Steady lights: ready”

Time to descale. The alert is triggered by how many drinks the machine has made, not by a timer.

What Nespresso says to do

  1. Empty the drip tray and the used-capsule container, plug the descaling pipe from the back of the machine into the steam connector, and fill the tank with 100 ml of Nespresso descaling agent and 500 ml of water.
  2. Enter descaling mode as the manual shows: the DESCALING alert then blinks orange for the whole process, which takes about 20 minutes.
  3. Rinse as the manual describes: refill the tank with fresh water and press Espresso; the rinse runs until the tank is empty and the machine switches off. Store the pipe, empty the tray and container, and refill the tank to MAX.

CLEAN alert lit orange

Cleaning due

Lights blinking irregularly

Fault or blockage

Several lights or symbols at once: flashing or blinking

A fault. Nespresso gives no home fix for blinking that matches none of the patterns above.

No light

Off or no power

Several lights or symbols: off

Usually the machine has switched itself off: it turns off 9 minutes after it was last used (the factory setting). If pressing a button does not wake it, it is getting no power.

“No light indicator. - Check the mains, plug, voltage, and fuse. In case of problems, call the Nespresso Club.”

Near relatives

Machines from the same maker whose lights are close to these, each on its own page from its own manual. A light that looks the same can still mean something else, so check each one.

When Nespresso says to get help

Call the Nespresso Club, or send the appliance for repair (the manual’s wording).
