Miele Dishwasher Error Code F13

F13 on a Miele dishwasher means the appliance did not detect the required number of flow meter pulses within the maximum 4-minute water intake period. In plain terms, the dishwasher could not fill with enough water in time and shut down to protect itself. This can be caused by low supply pressure, a blocked inlet filter, a faulty inlet valve, or a defective flow meter.

Resetting the dishwasher may temporarily clear the F13 display, but the error will return as soon as the machine attempts another fill cycle if the underlying problem has not been corrected. A reset is useful for confirming the fault is active and repeatable, but it is not a repair. The root cause of the restricted or slow water intake must be addressed first.

Repair costs vary depending on the cause. If the fix is simply cleaning a clogged inlet filter screen or adjusting a supply valve, costs may be limited to a service call fee in the range of $75 to $150. Replacing a faulty water inlet valve or flow meter typically adds parts and labor costs, bringing the total repair estimate to somewhere in the range of $150 to $400 depending on the specific parts needed and local labor rates.

Some causes of F13 are DIY-friendly. You can check that the shutoff valve is fully open, inspect the supply hose for kinks, and clean the inlet valve filter screen without special tools. If those steps do not resolve the error, diagnosing a faulty inlet valve or flow meter typically requires a qualified technician with the ability to test components and access internal parts safely.

You should not continue running the dishwasher while F13 is active. The error indicates the machine aborted a fill cycle because it could not intake water properly, which means wash cycles will not complete correctly and dishes will not be cleaned or rinsed adequately. Continuing to run the appliance without addressing the fault could also stress other components over time.
