Miele CVA 2650 Coffee Machine Fault
| Fault Code | Cause | Solution |
|---|---|---|
| F2 | Coffee/hot-water NTC open-circuited | Check/replace the coffee/hot-water NTC |
| Ambient temperature colder than 10°C (50°F) for a long period of time. With temperatures less than 10°C, the resistance of the temperature sensor increases to such a level that the electronic control registers an open circuit. | The ambient temperature must be above 15°C (59°F) for a long period of time before the appliance can be used again normally. Replacing the electronic module or the temperature sensor will not remedy the fault | |
| F3 | Steam NTC (1R30) short-circuited | Check/replace the steam NTC |
| F4 | Steam NTC (1R30) open-circuited | Check/replace the steam NTC |
| Ambient temperature colder than 10°C (50°F) for a long period of time. With temperatures less than 10°C, the resistance of the temperature sensor increases to such a level that the electronic control registers an open circuit | The ambient temperature must be above 15°C (59°F) for a long period of time before the appliance can be used again normally. Replacing the electronic module or the temperature sensor will not remedy the fault | |
