When your miele dishwasher won’t drain, the machine almost always shows F11 and leaves water sitting in the base of the tub. The most common cause — a clogged filter or a jammed drain pump impeller — is something you can often clear yourself.
Miele G-series dishwashers move water through a filter, circulation pump, and spray arms, and they report faults as F-codes such as F11 and F70, so confirming the water path and the Waterproof System float before suspecting electronics resolves most calls. We start with the everyday causes you can check yourself, then explain the signs that point to a part that genuinely needs a hands-on repair.
What a miele dishwasher won’t drain usually means
F11 means the dishwasher could not pump water out within its expected time. On Miele G-series machines water passes through the triple filter, the drain pump, and the drain hose to your disposer or standpipe. Anything restricting that path triggers F11, and a genuinely failed pump is the last suspect, not the first.
First checks you can do
Start with the checks you can safely do yourself. Each one rules out a common, inexpensive cause, and together they resolve the majority of cases without a service visit:
- Lift out and rinse the cylindrical triple filter in the base of the tub — food, glass, and seeds collect there.
- Scoop out standing water, then check the drain pump impeller (under the filter cover) for a shard of glass or a fruit pit jamming it.
- Straighten the drain hose behind the machine and confirm it is not crushed.
- If it drains into a disposer, confirm the knockout plug was removed at install and run the disposer to clear the shared connection.
Take these in order and test whether the problem has cleared before moving to the next. If you do end up needing help, having worked through them gives the technician a useful head start.
Reading the Miele display for a miele dishwasher won’t drain
Note any code before you act, because it narrows the diagnosis more than any other clue. A good first move for most Miele faults is a power reset: switch the appliance off at the wall or trip the breaker for a minute, then restore power. If the code returns straight away, treat it as a real fault pointing at the named part.
- F11 — drainage fault (the core code here): filter, pump impeller, hose, then pump motor.
- F70 — float / water in the base (Waterproof System); a leak rather than a drain fault.
- F12/F13 — water-intake faults, the fill-side opposite of F11.
- F68/F69 — circulation pump won’t stop or is blocked; not the drain pump but worth knowing.
Note the exact characters and any plain-English message Miele shows alongside the F-number, since the wording often tells you which subsystem the control suspects.
When it is a fault, not a habit
If the everyday checks above do not resolve it, the problem has likely moved from something you can adjust to a component that needs testing or replacing. These are the signs that point that way:
- The filter and impeller are clear but F11 returns — the drain pump motor or its control may have failed.
- You hear the pump hum but no water moves, which points to a seized impeller.
- A blocked or kinked in-cabinet hose section that needs the side panel removed.
At this point a proper diagnosis beats guesswork, since the remaining causes involve a specific part or electrical testing. An experienced technician can meter the suspect component and fit a genuine Miele part so the repair lasts.
Putting it together
Work the checks above in the order given. Most Miele dishwasher faults of this kind clear at one of the early, owner-checkable steps; the ones that do not point to a specific part and are worth a proper diagnosis rather than guesswork. Move from the simplest cause outward, confirm each step before the next, and treat a returning code or a lingering symptom as your cue to bring in help. A little routine care afterwards prevents most repeat calls, since Miele builds these dishwashers to a high standard.
