Miele Dishwasher F11 Error Code: Causes & Fix

What is the Miele Dishwasher F11 error?#

F11 on a Miele dishwasher is a drainage fault: the machine tried to pump out but the water level did not drop in time, so it stops with standing water in the tub. Good news — this is one of the most owner-fixable Miele codes, rated easy. Before anything else, pull the coarse filter in the base of the tub and clear it, because a clogged drain filter is the number-one trigger and the number-one thing I find on a call.

F11 on a Miele Dishwasher: likely causes and repair cost#

On a Miele Dishwasher, the F11 code signals: drainage error.

Typical professional repair: $200–$400 · Difficulty: easy · often owner-fixable

Fastest thing to try first: Check drain hose position and clean filter.

Symptoms that often accompany F11: Standing water in tub; Foul odor from dishwasher; Cycle completes but dishes still wet at bottom

Technician diagnostic sequence for F11:

1. Remove and clean the triple-filter system at the bottom of the tub
2. Check drain hose for kinks — must have high loop or air gap
3. Run a rinse cycle to test drainage
4. If still blocked, check the drain pump impeller for debris
5. Verify garbage disposal knockout plug is removed if newly installed

Parts a technician may check or replace: if motor failed; if damaged

Field note: Listen for the drain pump humming without water moving — indicates a blockage, not motor failure. Miele triple-filter systems trap debris effectively but need monthly cleaning.

Safety note: Miele drain hose must maintain a high loop of at least 24 inches to prevent backflow from the sink drain.

How to troubleshoot the F11 error yourself#

Work from the cheapest, most common cause outward. Begin by scooping out any standing water, then lift out and rinse the filter assembly in the sump — food debris packed into the mesh is the usual culprit and clears in minutes. Next, trace the drain hose behind the machine and straighten any kink; a hose crushed against a cabinet wall or crammed behind a bin stops flow completely. Then check the drain pump itself: with power off, look in the sump for a shard of glass, a fruit sticker, or a bit of cutlery jamming the impeller, and clear it by hand. Run a short cycle to confirm the water leaves. If the tub still will not empty after the filter, hose, and pump are all clear, the pump motor may have failed — that is where a DIY job becomes a technician one.

Is the Miele Dishwasher F11 error worth fixing?#

Firmly worth fixing, and often free. Because clearing the filter or unkinking the hose costs nothing, most F11 calls never need a paid repair at all. When the drain pump has actually failed, a professional job runs $200–$400, still a small fraction of a new Miele and well under half its price. I have never advised replacing a dishwasher over an F11 — the fault sits in cheap, serviceable parts at the bottom of the machine, not in anything that threatens the unit's value.

Miele Dishwasher F11: frequently asked questions#

What does F11 mean on a Miele dishwasher?#

It signals a drainage error: the dishwasher could not pump its water out within the expected time, so it halts with water left in the tub.

Is it safe to keep using a dishwasher showing F11?#

It will not drain, so running it again just leaves more standing water. Clear the filter and hose first; there is no safety risk, only a machine that cannot finish a cycle.

Can I clear F11 myself?#

Usually yes. Cleaning the sump filter, straightening the drain hose, and clearing the pump of debris resolves most F11 cases without any tools beyond a sponge.

How much does F11 cost to repair?#

Often nothing if it is a clogged filter or kinked hose. If the drain pump has failed, a professional replacement runs $200–$400.

Which parts fail when a dishwasher throws F11?#

Rarely a part at all — it is usually a blocked filter or hose. When a part is at fault, it is the drain pump or a foreign object jamming its impeller.

Why does a clogged drain filter trigger F11?#

A packed filter starves the drain pump of flow, so the water level barely moves. The board sees the tub failing to empty and posts F11.
