What F11 means (miele f11 error)
A miele f11 error is the Miele dishwasher service fault code for a drainage problem — the control did not see the water level fall as the drain pump ran. Miele usually shows the plain-English prompt to check the drain, and the most common cause is a blocked filter or drain hose rather than a failed pump.
Symptoms to look for
The signs below help confirm you are dealing with this condition rather than a different fault on your Miele Dishwasher. You may see one of them or several together, and they can build up gradually or appear suddenly after a power event, a long door opening, a spill, or recent service.
- F11 appears and standing water is left in the base
- The dishwasher stops part-way through the cycle
- You may hear the drain pump running without clearing water
- Dishes finish wet with residue at the bottom
Common causes
Several different faults can produce these symptoms. Working through the most likely causes in order helps separate a quick, owner-level check from a problem that needs trained service and the correct Miele parts.
- Blocked drain filter — food debris clogs the coarse/fine filters in the base
- Kinked or blocked drain hose — the hose is pinched, clogged, or looped wrong
- Clogged sump or non-return valve — debris jams the drain path
- Failed drain pump — the pump no longer moves water
Troubleshooting steps you can try
Work through these checks in order before calling for service. Stop wherever you are unsure, or where high-voltage parts, gas, the sealed refrigeration system, or a heat-pump compressor are involved, and hand the rest to a qualified technician.
- Switch off, then lift out and rinse the coarse and fine filters in the base.
- Check the drain hose is not kinked and the air gap or sink-drain connection is clear.
- Clear any debris (glass, labels, food) from the sump and pump area you can safely reach.
- If water still will not drain with a clean filter and hose, leave it for service.
Parts a technician may replace
Depending on what the diagnosis shows, a technician may inspect, test, or replace the drain pump, drain filter, non-return valve, drain hose, and sump. The correct part for your Miele Dishwasher is matched from the model and serial number, and genuine Miele components are fitted through trusted parts suppliers rather than generic substitutes so that performance, safety, and the appliance’s long working life are all protected. Confirming the failed part before ordering avoids replacing more than the fault actually requires.
When to call a technician
F11 that stays after cleaning the filter and hose needs a technician to test the drain pump and non-return valve. When the fix calls for trained service, book a visit through our scheduling page and an experienced, qualified technician will diagnose and repair it.
Prevention and care
Regular care keeps this condition from returning on your Miele Dishwasher. Keep filters, vents, seals, and the condenser, exhaust, or burner path clean, avoid overloading or blocking airflow, check that doors and seals close cleanly, and follow the Miele maintenance guidance for your model. Because this unit relies on electronic control, protect it with a stable, correctly rated power supply and have any built-in or laundry installation done to Miele specification so the control never sees an out-of-range condition. If a code appears, note exactly what was shown before you reset the appliance — that record helps the technician reach an accurate diagnosis and avoid replacing parts unnecessarily.
