Miele Dishwasher Not Draining: F11 & F14 Error Code Diagnostic
Quick answer
A Miele dishwasher that won't drain — often showing an F11 error — is most commonly caused by a clogged triple-filter assembly at the bottom of the tub. Remove the lower basket, lift out the filter system (the cylindrical coarse filter and flat fine-mesh filter), rinse both under hot water, and reinstall. This resolves most F11 drain faults in under 10 minutes without tools.
Miele dishwashers — including the G 7000 series, Dimension, and older G-series units — are built for 20,000 wash cycles, but the F11 drain fault is one of the most common service requests we receive for this brand across Northern Virginia. The F11 (intake/drainage) and F14 (drain) error codes both indicate the dishwasher failed to drain within the expected window. In the majority of cases, the cause is a clogged filter or blocked drain hose — homeowner-accessible steps that resolve the problem without a service call.
1. Clean the triple-filter assembly
Miele uses a three-part manual filter system: a cylindrical coarse filter at the center of the tub floor, a flat fine-mesh filter beneath it, and a microfilter screen. This system must be cleaned regularly — Miele recommends monthly cleaning, but in practice many owners have never serviced it. A fully loaded filter creates enough back-pressure to prevent the drain pump from evacuating the tub within the required cycle time, triggering F11. Remove the lower basket and locate the cylindrical filter at the center of the tub floor. Rotate it counterclockwise and lift it out, then lift out the flat filter beneath. Rinse both under hot running water, scrubbing with a soft brush if needed. Replace the flat filter first, then the cylindrical, rotating clockwise until it locks. Run a short rinse cycle — most F11 faults clear immediately after filter cleaning.
2. Check the drain hose for kinks and high-loop routing
The drain hose runs from the Miele drain pump to either the sink drain tailpiece or a garbage disposal inlet. A kinked hose, a collapsed section from age, or debris accumulation at the disposal connection blocks drainage without any pump fault. Inspect the hose behind the unit for visible kinks — it should form a 'high loop' up toward the underside of the counter before dropping to the drain connection. If the hose hangs low, wastewater siphons back into the tub during the cycle. If the dishwasher drains to a garbage disposal, confirm the disposal's knockout plug is removed (a new disposal installation with the plug in place is a common cause of F11). Run the disposal for 30 seconds immediately before starting a dishwasher cycle to clear debris at the connection point.
3. Inspect the sump area for foreign objects
With the filter assembly removed, shine a flashlight into the sump cavity beneath. Small foreign objects — broken glass, fruit pits, plastic utensil tips, bottle caps — can reach the sump and jam the drain pump impeller. On Miele dishwashers, the drain pump inlet is accessible from the sump with the filter removed. Carefully feel for and remove any debris. The impeller should rotate freely with light finger pressure when no obstruction is present. A hard stop indicates a lodged object; gritty resistance indicates fine debris or bearing wear. Replacing a Miele drain pump is a technician repair due to the base panel access required.
4. Understand F11 vs F14 error codes
Miele uses two drain-related fault codes on G-series and Dimension dishwashers. F11 is the general intake/drain fault — displayed when the machine cannot complete a drain sequence within the expected time window. F14 specifically indicates the drain pump is detected as running but the tub water level is not dropping — the pump is energized but not moving water, pointing to a jammed impeller or failed pump motor. On newer Miele models, the error code shows on the door display; on older G-series models, a combination of indicator light flashes communicates the code. After clearing a blockage, reset the Miele dishwasher by pressing and holding the Start button for 4 seconds, or by switching the machine off and back on at the power switch. If F11 returns on the next cycle after a full filter cleaning, the drain pump or control module requires professional diagnosis.
When to Call a Specialist
Cleaning the Miele triple-filter and inspecting the drain hose are straightforward homeowner steps with no tools required. Accessing the drain pump requires removing the base panel and dishwasher plumbing connections — this is technician work. Miele drain pump replacement involves the base panel, door harness, and specific Miele torque specs; incorrect reassembly can void the waterproof certification. We service Miele dishwashers across McLean, Great Falls, Vienna, Arlington, Bethesda, Potomac, and all of Northern Virginia and Washington DC.

Frequently Asked Questions
What does the Miele F11 error code mean?
The Miele F11 error code indicates an intake/drainage fault — the dishwasher did not complete its drain cycle within the expected time window. The most common cause is a clogged triple-filter assembly at the bottom of the tub. Remove the lower basket, take out the cylindrical and flat filters, rinse both under hot water, and reinstall. This resolves most F11 errors in under 10 minutes. If F11 returns after cleaning the filter, the drain hose connection or drain pump requires inspection.
How do I reset a Miele dishwasher showing F11?
After clearing the filter and drain hose, reset the Miele dishwasher by pressing and holding the Start/Stop button for approximately 4 seconds until the machine resets, or by turning the program selector to Off and back to your chosen program. On Miele Dimension models with a touch panel, hold the On/Off button for 4 seconds. If F11 reappears on the next cycle, the drain pump or machine electronics require professional diagnosis — a power-cycle reset does not clear a hardware fault.
