Water Level Sensor Error (Analog)
The analog pressure switch has detected an overfill condition, common in models with auto water level detection.
Reset the appliance. Check the pressure switch and its hose for blockages. The inlet valve could also be stuck open.
Bauknecht F42: Operational cycle fault detected during Hob / Cooktop program execution.
A button on the touch control has been pressed for too long, or there is moisture/debris on the surface.
Ensure the hob surface is clean and dry. Reset the hob by turning off the power at the circuit breaker for a few minutes.
Bauknecht F43: Operational cycle fault detected during Hob / Cooktop program execution.
The pan is not induction-compatible, not centered correctly, or has been removed from the cooking zone.
Use only induction-ready cookware. Ensure the pan is centered on the cooking zone and is flat on the surface.
Internal Communication Error
Communication failure between the user interface board and the power module(s).
This is an internal fault. Resetting power at the breaker may help, but it often indicates a need for service to check internal wiring or boards.
Bauknecht F6 E4: Water inlet / filling timeout in Dishwasher; appliance fails to fill to minimum operational level.
The dishwasher is taking on water when it should not be, or the flowmeter is faulty.
Check the water inlet valve to ensure it is not stuck open. Inspect the flowmeter and its wiring.
Drain Fault / Water Not Emptying
The drain pump is blocked, the drain hose is kinked or blocked, or the water level sensor is faulty.
Clean the filters and check the drain pump impeller for obstructions. Ensure the drain hose is not kinked.
Bauknecht FDL: Door lock safety interlock fault in Washing Machine; door switch contact fails to close or open.
The door is not locking correctly when a cycle is started.
Check for obstructions preventing the door from closing fully. Inspect the door latch and the lock mechanism for damage.
Bauknecht FDU: Door lock safety interlock fault in Washing Machine; door switch contact fails to close or open.
The door lock mechanism has failed to release at the end of the cycle.
Wait 5 minutes for the safety release. If it still won't open, use the manual release tab (if available). The door lock assembly may need replacement.
Bauknecht FOD: Operational cycle fault detected during Washing Machine program execution.
Excessive suds have been detected by the pressure sensor, usually due to using too much or the wrong type of detergent.
Allow the machine to run through its anti-foam routine. Run an empty rinse cycle to clear suds. Use less detergent in subsequent washes.
Bauknecht H: NTC temperature sensor signal out of range (open or short circuit) in Dishwasher.
This usually indicates a fault with the NTC temperature sensor, causing the water to overheat.
Test the NTC sensor's resistance and check its wiring. Replace if defective.
Function stopped during pyrolytic cleaning
The self-cleaning cycle was interrupted due to a fault, such as overheating or a component failure.
Allow the oven to cool down completely. Once cool, try starting a regular cooking function. If 'STOP' persists, professional service is required.
