Nespresso Lattissima One Not Working? 5 Fixes (F111)

What the Lattissima One's Lights Are Telling You

The Nespresso Lattissima One (F111) reports most problems through its lights: three drink buttons and two orange alerts, DESCALING and CLEAN. A CLEAN alert means wash the milk system. All three buttons blinking fast three times means the water tank is empty. If all the buttons blink together for 10 seconds and then it switches off, Nespresso calls it an "error alarm": the machine needs repair.

The milk side is the Rapid Cappuccino System: a milk jug, lid, aspiration tube, milk spout and a removable air inlet. Nespresso designed it for skimmed or semi-skimmed cow's milk at fridge temperature, not plant milk, and it needs washing after every milk drink. This page follows Nespresso's Lattissima One (F111) user manual.

Quick Checks

• Is a light pattern showing? Match it in the table below before trying anything else.
• Water tank filled? All three buttons blinking fast three times, then going back to ready, means it's empty.
• Just connected the milk jug? The machine heats for about 15 seconds (blinking lights) before a milk drink.
• Lever won't close? Empty the used-capsule container and check that no capsule is stuck in it.

Lattissima One Lights, From the Manual

Fix 1: Clean the Milk System When CLEAN Lights

After every milk drink the CLEAN alert turns orange. Nespresso says to clean the Rapid Cappuccino System within 30 minutes of the drink.

1. Take it off: press the button on the side of the milk jug and pull to unlock the connector. Remove the milk container and unplug the aspiration tube.
2. Take it apart: turn the milk spout upright, press the side button and pull the spout out. Remove the lid and the air inlet (it's removable).
3. Dishwasher: put all the parts in the upper rack.
4. By hand (Nespresso says do it after each use if you have no dishwasher): rinse off the milk with hot water at about 40 °C (104 °F). Soak every part in 40 °C water with a mild detergent for at least 30 minutes, then rinse well with hot water. Clean inside the milk tank with mild detergent, and make sure the air inlet is clean. Dry everything and reassemble.
5. Don't use abrasive materials, and don't store the milk system in the fridge. Nespresso says it isn't designed to be.

Time: 5 minutes (dishwasher) or 35 minutes (by hand)

Fix 2: Milk Froth Not Right

Nespresso's troubleshooting lists five things for poor milk froth:

1. Use skimmed or semi-skimmed cow's milk at fridge temperature (about 4 °C). "The milk system has not been designed to work with vegetable milk."
2. Don't use frozen milk.
3. Clean the system after every milk drink (Fix 1).
4. Make sure the air aspiration part (air inlet) is clean.
5. Descale the machine (Fix 4).

Also check the fill level. The jug has two marks, one for Cappuccino and one for Latte Macchiato. All the milk in the jug goes into the drink, and Nespresso says the froth volume depends on the milk you use and its temperature. The milk system won't run on water.

Time: 5 minutes
Cost: Free
Difficulty: Easy

Fix 3: No Coffee, Slow Coffee or Only Water

To brew, lift the lever completely, insert the capsule and close it. Then press Espresso (40 ml) or Lungo (110 ml). You can press a coffee button while it's heating, and the coffee starts once the machine is ready.

Time: 2 minutes
Cost: Free
Difficulty: Easy

Fix 4: Descale When the Alert Shines Orange

Allow about 20 minutes.

1. Lift and close the lever to eject any capsule. Empty the drip tray and the used-capsule container.
2. Fill the water tank with 100 ml of Nespresso descaling agent and 500 ml of water.
3. Take the descaling pipe from the back of the machine and plug it into the steam connector. The machine enters descaling mode: the DESCALING alert blinks orange and the Espresso button lights white.
4. Put a container of at least 1 litre under both the coffee outlet and the descaling pipe. Press Espresso. The solution runs through the coffee outlet, the descaling pipe and the drip tray until the tank is empty, and then the Espresso button lights.
5. Empty the used-capsule container, drip tray and container. Rinse the tank and fill it with fresh water to MAX.
6. Press Espresso again to rinse. When the rinse ends, the machine switches off. Remove and store the descaling pipe. Empty the drip tray and capsule container and refill the tank.

Alert still on after descaling? See Nespresso descale light won't turn off. Can't enter Menu mode afterwards? Nespresso's manual says to remove the milk jug and the descaling pipe first.

Time: About 20 minutes
Cost: Nespresso descaling agent
Difficulty: Easy

Fix 5: Restore the Drink Volumes

Nespresso documents one reset on the F111, headed "Restoring quantity to factory settings". It restores drink volumes, not the whole machine, and the manual doesn't offer it as a fix for error lights.

1. Switch the machine on and remove the milk jug.
2. Press the milk button for 3 seconds to enter Menu mode. The DESCALING and CLEAN alerts start blinking. That's the menu, not a fault.
3. Press the milk button. It blinks to show reset mode.
4. Press it once more to confirm. All the buttons blink 3 times, and the machine leaves the menu and returns to ready.

Changed your mind? Menu mode closes after 30 seconds, or you can hold the milk button for 3 seconds. It's the milk button, not the coffee buttons. Pressing Espresso and Lungo together for 2 seconds turns the machine off.

After the reset: Espresso 40 ml, Lungo 110 ml, milk drinks 50-125 ml, and automatic power off after 9 minutes. You can program coffee volumes from 25 to 150 ml. Nespresso warns that if you program more than 150 ml, you should let the machine cool for 5 minutes before the next coffee.

Time: 1 minute
Cost: Free
Difficulty: Easy

When the Lattissima One Needs Service

• All buttons blink for 10 seconds, then it switches off, irregular blinking, or only water despite a capsule: Nespresso says to send it for repair or call. In the US, Nespresso's number is 1-800-562-1465.
• Leaving it unused, in the cold, or sending it for repair? The manual has an emptying routine. With the machine on and the tank removed, enter Menu mode, press milk + Lungo together, then confirm with the milk button. It's blocked for about 10 minutes afterwards.
• Warranty: the manual we read gives a 2-year Nespresso limited warranty from purchase, repair or replace. It excludes damage from calcium deposits or not descaling.

Prevention

• Clean the milk system after every milk drink, within 30 minutes.
• Descale when the alert shines orange. Set your water hardness with the test strip (Menu mode, then Espresso), so the alert matches your water.
• Daily: empty and rinse the drip tray and capsule container, refill the tank with fresh water, and run a Lungo of water to rinse.
• Protect it from frost. Nespresso warns that cold storage can damage the water circuit and cause leaks. Empty the system first.

FAQ

Why is the CLEAN light orange on my Lattissima One?

It lights after every milk drink to tell you to clean the Rapid Cappuccino System. Take it apart and wash it in the dishwasher's upper rack, or by hand in 40 °C water with mild detergent.

Can I use oat or almond milk in a Lattissima One?

Nespresso says the milk system "has not been designed to work with vegetable milk". It recommends skimmed or semi-skimmed cow's milk at about 4 °C.

What does it mean when all the buttons flash and the Lattissima One turns off?

If all the buttons blink together for 10 seconds and then it switches off, Nespresso calls it an error alarm: the machine needs repair. If the coffee and milk buttons flash alternately instead, it has overheated. Let it cool.

How do I turn off the Lattissima One?

Press Espresso and Lungo together for 2 seconds. It also switches itself off 9 minutes after the last use (factory setting).
