The short answer: a Miele dishwasher that won't drain almost always comes down to a clogged filter, a blocked or jammed drain pump, a stuck non-return (check) valve, or a kinked drain hose. Miele dishwashers are engineered for a long service life, so a drainage fault is usually a repairable blockage or pump issue — not the end of the machine.
The most common reasons a Miele won't drain
Miele uses a fine multi-stage filter at the base of the tub. Food particles, grease, and debris accumulate there and restrict drainage. Remove and rinse the filter under hot water — this is the first and most common fix for a Miele that won't drain.
Below the filter sits the drain pump. A foreign object — glass, a seed, a label — can jam the impeller, or debris can restrict it. With power off, the pump area can be checked and cleared. A pump that's truly failed needs replacement.
Miele dishwashers use a non-return valve to stop drained water from flowing back into the tub. If it sticks closed with debris, water can't exit; if it sticks open, dirty water returns. Cleaning or replacing the valve restores proper drainage.
A drain hose that's kinked behind the unit, or a clogged under-sink connection or air gap, prevents drainage. The hose routing and the garbage-disposal/air-gap connection should be checked, especially after any recent work under the sink.
If the filter, pump, valve, and hose are all clear but the dishwasher still won't drain — or shows a fault code — the drain pump may have failed electrically, or the control needs diagnosis. Miele's electronics and pumps are precision components best tested by a technician familiar with the platform.
What you can safely check yourself
- Clean the filter: Twist out the multi-stage filter at the bottom of the tub and rinse thoroughly under hot water. This resolves most Miele drainage complaints.
- Bail and check the pump: Remove standing water with a cup and sponge, then inspect the pump area under the filter for debris or foreign objects (power off).
- Check the drain hose: Make sure it isn't kinked behind the unit and the under-sink/air-gap connection is clear.
- Inspect the non-return valve: Look for debris holding the small check valve open or closed near the sump.
- Run a rinse cycle: After clearing, run a short cycle to confirm water drains fully before assuming it's fixed.
If the filter and pump are clear and your Miele still holds water, SAVA diagnoses the non-return valve, drain pump, and control. Miele is the most common premium dishwasher on the North Shore and we service it throughout Chicago and the suburbs.

Why is there standing water in my Miele dishwasher after a cycle?
The most common causes are a clogged filter, a blocked or jammed drain pump, a stuck non-return valve, or a kinked drain hose. Start by cleaning the multi-stage filter at the base of the tub — it resolves most Miele drainage problems.
How do I clean the filter on a Miele dishwasher?
Remove the lower rack, twist out the cylindrical multi-stage filter at the bottom of the tub, and rinse it under hot running water to clear trapped food and grease. Reseat it firmly. This is the first fix to try for drainage problems.
Where is the drain pump on a Miele dishwasher?
The drain pump sits below the filter at the base of the tub. With power off and standing water removed, the pump area can be checked for a foreign object jamming the impeller — a common cause of no-drain faults.
Is it worth repairing a Miele dishwasher?
Almost always, yes. Miele dishwashers are engineered and tested for around 20 years of use — far longer than most brands — so a drainage fault is usually a repairable blockage, valve, or pump issue rather than a reason to replace the machine.
Do you repair Miele dishwashers in Chicago?
Yes. Miele is the most common premium dishwasher in Chicago's North Shore suburbs, and SAVA services it throughout the area — drainage faults, drain pump and non-return valve repair, inlet-valve and control-board issues. Same-day service is often available.
My Miele shows a fault code and won't drain — what should I do?
A drainage fault code after the filter and pump are clear usually means the drain pump has failed electrically or the control needs diagnosis. Call (773) 558-3332 — these precision components are best tested by a technician familiar with Miele.
