Nespresso Lattissima F321/F316 serves a very short cup
ErrorShort cup — Lattissima F321/F316
Official Nespresso guidance for Nespresso Lattissima F321 and F316 machines covered by the Chile support entry explains the Lattissima serves less coffee or latte than the programmed button normally delivers. The behavior is model-specific and should not be merged with another Nespresso machine family.
What the code means
The cup-size button programming has changed from the factory setting
The machine and milk outlet may be hot. Keep hands clear during the reset test.
Typical symptoms
01The Nespresso Lattissima F321 and F316 machines covered by the Chile support entry shows the Lattissima serves less coffee or latte than the programmed button normally delivers

- 2Turn the machine on and allow it to reach operating temperature
- 3Hold the standby button until all four cup buttons flash
