What F194 Means
F194 is the open-circuit counterpart to F193 on the bottom-heat Pt1000 sensor: instead of an impossibly low reading, the control gets no reading at all. Miele’s remedy is the same — inspect the harness, then fit a new sensor with its wiring.
Common Causes of F194
- Bottom-heat Pt1000 sensor failed open
- Break in the sensor harness
- Connector unseated at the power electronics
🔧 One Safe Check You Can Try
Switch the oven off at the breaker before you go near it. Then simply record what the oven does when you try to bake: many owners find the base function has quietly dropped out while the top elements still work, and that observation shortens the visit.
⚠ Why You Shouldn't Go Further Than That
- An open circuit can sit anywhere between the sensor tip and the board, and finding where means metering the run rather than guessing at the ends.
- The replacement is supplied as a sensor-and-harness assembly, routed a particular way, and a cable laid carelessly will chafe through in the same place again.
- Access runs through the cavity floor and the insulation behind it, which has to be put back correctly or the oven loses efficiency and runs hot outside.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
