Appliance Coffee Machine
Quick answer

F3 is a heating system problem on a Miele coffee machine, with cool-down and room temperature steps.

Model compatibility

Miele reuses codes across series and model years, so F3 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Plain language

What this code means

F3 is a heating system problem.

F3 shows up when a Miele coffee machine has a heating system problem. The two questions to answer are how hot the machine got and how cold the room was.

What it means F3 is a heating system problem.
What you can check Switch the machine off at the On/Off switch and wait an hour. If the room stayed below 10 C for a long time, keep it above 15 C for an extended period before the next use.
When to call a technician If F3 stays on after the machine has cooled and the room has warmed up, a repair visit is the next step.
  1. Machine too hot: turn it off with the On/Off switch and wait an hour.
  2. Room too cold: if it stayed below 10 °C for a long time, keep it above 15 °C for an extended period before the next use.
