Miele Washer Error Code F 19

F 19 means the flow meter, component B3/4, is sluggish or not sending a signal to the control board. The washer detected that the water level is rising but received no corresponding pulse from the flow meter to confirm and measure that flow. The machine halts to prevent an uncontrolled fill condition. This fault typically points to a blocked flow meter rotor, a wiring issue, or a restricted water inlet.

No, you should not continue running the washer while F 19 is active. The machine has halted the cycle because it cannot reliably monitor how much water is entering the drum, which creates a risk of overfilling. Address the underlying cause before attempting to restart a wash cycle.

If the fix is simply cleaning the inlet filter screens or flushing debris from the flow meter, the repair can cost very little beyond your time. If the flow meter B3/4 needs to be replaced, parts and labor costs typically range from around $150 to $400 depending on your location and whether you use a Miele-authorized service technician or a general appliance repair professional. Wiring repairs generally fall toward the lower end of that range.

Start by following the F 10 water intake diagnostic procedure: check that the water supply valve is fully open, inspect and clean the inlet filter screens at the back of the machine, and confirm adequate water pressure. If the supply side is fine, locate the flow meter B3/4 on the inlet path, remove it, and flush it to clear any debris or scale blocking the rotor. If cleaning does not resolve the fault, test the signal wiring for continuity and replace the flow meter if it is defective.

A reset may temporarily clear the code and allow the machine to restart, but F 19 will return if the underlying fault is not corrected. The control board will detect the same mismatch between the level sensor and the flow meter signal as soon as the next fill cycle begins. Resetting without fixing the root cause is not a lasting solution.
