What it means
F1 is a heating system problem, with the coffee machine overheating.
What you can check
Switch the machine off at the On/Off switch and give it a full hour to cool. If the room stayed under 10 C for a long time, warm it above 15 C and keep it there before use.
When to call a technician
F1 staying on the display after the cool-down and, where relevant, the room warming up calls for a service visit.
Overheating
Turn the machine off using the On/Off switch and give it a full hour to cool.
A cold room
Where the room temperature stayed under 10 °C for a long stretch, bring it above 15 °C and keep it there for an extended period. Only then should the machine go back into use.
