There are three things that could lead to this happening:
- The pod collection basket is full. If so, simply empty it.
- The water level might need to be topped up.
- Occasionally, after preparing a few coffees in a short space of time, your machine may go into calibration mode. This is to let the machine cool down so the next coffee can be extracted at the perfect temperature. After a few minutes the blinking will stop and the machine will be ready to make another coffee.
