Miele Dishwasher Intake/Drain Light: What It Means
Miele dishwashers announce water-path trouble with the Intake/Drain indicator, or on display models with fault codes in the F11 to F13 family, and the wording is precise: the machine could not move water in or out the way it expected. Miele engineering rewards owners who know two specific service points, because both are designed to be user-accessible and both solve most of these lights.
Service point one: the triple filter
At the tub floor sits Miele's filter combination: turn the handle, lift out the assembly, and separate the coarse, fine and micro elements. Rinse everything under hot water and brush the fine mesh; Miele filters are efficient enough that a season of neglect visibly mats them. Refit and twist until the arrows lock, because an unlocked filter can re-trigger the fault by itself, and it also lets debris reach the pump you are about to meet.
Service point two: the non-return valve
Here is the Miele-specific step most owners never learn: beneath the filter well sits an accessible non-return valve over the drain pump. With the filter out and the sump sponged dry, release the valve per your model's manual, lift it out, and clear what you find, glass shards, fruit stones and plastic film are the regulars. Check that the pump impeller beneath turns freely, using a cloth against glass. Reseat the valve until it clicks. This one check resolves a large share of drain-side faults on this brand.
The intake side and the house connections
If the light points at intake, confirm the water tap is fully open and the inlet hose unkinked. Miele's Waterproof System hardware is conservative by design; a machine that repeatedly refuses to take water with a good supply is protecting itself and wants a technician rather than persistence. Under the sink, the drain hose needs its high loop, and on new installations the disposal knockout plug remains the classic culprit, the same trap covered in our Bosch drain guide.
Reset, once, then respect the light
After servicing both points, switch the machine off and on and run a short program. Miele controls are exact: a fault that returns on clean hardware is reporting a real component, pump, valve or sensor, and these machines justify brand-experienced repair; they are engineered for twenty-year service lives, which flips the repair math firmly toward fixing.
When to book
Book for any returning Intake/Drain indication, for F-codes that survive the two service points, or for water remaining after cycles.
