MODEL-SPECIFIC QUICK ANSWER
Nespresso Lattissima One blinking lights and common signals
On the Lattissima One, blinking buttons during the roughly 25-second heat-up is normal. Three quick flashes from all buttons indicate an empty water tank; all buttons blinking for about 10 seconds before shutdown is an error alarm that needs Nespresso service.
