Tumble Dryer
F11
If your Miele tumble dryer has suddenly stopped mid-cycle and flashed up an F11 error code, don’t panic — you’re not alone. The F11 fault code is one of the more common errors reported by Miele tumble dryer owners across the UK, and in many cases it can be resolved without an expensive call-out. In this guide, we’ll explain exactly what the F11 code means, walk you through the most likely causes, and give you clear, step-by-step instructions to get your dryer back up and running. We’ll also let you know when it’s time to put the tools down and call a qualified appliance engineer.
What does this error mean?
The F11 error code on a Miele tumble dryer indicates a drainage fault. Specifically, it means the appliance has detected that condensed water is not draining away properly — either from the condenser unit, the water collection tank, or the drainage pump itself. Miele tumble dryers (particularly condenser and heat pump models) collect the moisture extracted from your laundry as water. When the system that manages this water becomes blocked, full, or develops a fault, the machine triggers the F11 code and stops operating to prevent internal damage or flooding. In short: your dryer is telling you it has a water drainage problem.

DIY fix (cleaning filters, emptying tank, clearing blockage): £0 — just your time. Condensate pump replacement (parts + labour from an independent engineer): £80–£160. Call-out and diagnostic fee from an independent appliance engineer in the UK: £50–£90. Miele-authorised engineer call-out: £90–£140 for the first hour. PCB/control board replacement: £180–£350 parts and labour. Full Miele service plan (via Miele UK): from approximately £12–£20/month depending on appliance age and coverage level.
🔍 Likely causes
🛠️ Step-by-step fix
Step 1 – Switch off and unplug the dryer. Before you do anything else, turn your Miele tumble dryer off at the appliance and unplug it from the wall socket. Safety first — always disconnect from the mains before inspecting any internal components.
Step 2 – Empty the water collection tank. Pull out the condensate water drawer (usually located at the top-left or top-right of the machine, depending on your model). Empty it completely into a sink, rinse it out, and slide it firmly back into place until it clicks. This alone fixes the F11 error in a large proportion of cases. If you find the drawer was not actually full, move on to the next steps.
Step 3 – Clean the door fluff filter. Open the dryer door and remove the lint filter from inside the drum opening. Peel off any accumulated fluff by hand, then rinse the filter under warm running water. Use a soft brush if needed. Allow it to dry before reinserting. A blocked lint filter is a major contributor to drainage and condensation problems.
Step 4 – Clean the plinth (base) filter and condenser unit. Many Miele condenser dryers have a secondary filter behind a panel at the base of the machine. Open this panel (it usually unclips or has a small handle), remove the filter, and rinse it thoroughly under warm water. Behind this, you will often find the condenser unit itself — a finned, radiator-like component. Rinse this gently under a shower head or tap to flush out trapped lint and debris. Leave both to dry fully before replacing.
Step 5 – Check the drain hose (plumbed-in models only). If your Miele dryer is connected directly to a household wastewater pipe rather than using the removable tank, inspect the drain hose at the back of the machine. Check for kinks, bends, or blockages along its length. Disconnect it carefully (have a towel ready for water spillage) and flush it through with warm water to clear any obstruction. Ensure the hose is not pushed too far into the standpipe, as this can cause siphoning.
Step 6 – Inspect and clean the condensate pump. On many Miele condenser dryers, there is a small pump that moves the collected water from the condenser area into the tank or out through the drain hose. Access is usually via the base filter compartment. Once the filter is removed, you may be able to see a small pump impeller (fan-like wheel). Use a torch to check for any visible fluff or debris blocking the impeller, and remove any obstruction carefully with tweezers or a cotton bud. Be cautious — there will likely be residual water in this area.
Step 7 – Reset the machine. Once you have completed the relevant steps above, plug the dryer back in, switch it on, and run a short timed drying programme. Check whether the F11 error has cleared. If the machine completes the cycle without displaying the fault, the issue has been resolved.
Step 8 – If F11 persists, run a diagnostic reset. On many Miele models, you can attempt a hard reset by holding the Start/Stop button for approximately 5 seconds with the door closed. Alternatively, leave the machine unplugged for 10–15 minutes to allow the control board to fully reset before trying again. Consult your specific model’s user manual for the correct reset procedure, as this can vary between Miele dryer ranges (T1, TWI, TWF, etc.).
📞 When to call a professional
You should contact a qualified appliance engineer if: the F11 error code returns immediately after you’ve cleaned all filters, emptied the tank, and checked the drain hose; you suspect the condensate pump has failed mechanically (you may hear a humming noise but no water movement, or no sound at all from the pump); the error appears alongside unusual noises, burning smells, or visible water leaking from the machine; your machine is still under Miele’s warranty (typically 2 years standard, or up to 10 years if registered), in which case contact Miele UK directly on 0330 160 6600 to avoid voiding the warranty; or if you are not comfortable accessing the internal components of your appliance — there is no shame in calling a professional, and it is always the safer option.
⚖️ Repair or replace?
For most F11 faults caused by blockages or a full water tank, repair is the obvious and cost-effective choice — especially given Miele’s reputation for building long-lasting appliances. If the condensate pump has failed, a replacement pump and labour will typically cost less than a new dryer, so repair still makes sense if your machine is under 8–10 years old. However, if the fault is traced back to a failed PCB (control board), you should weigh up the repair cost against the age of the machine. A PCB replacement on a Miele dryer can cost £180–£350 including parts and labour, at which point a newer, more energy-efficient model may offer better long-term value — particularly if your current dryer is over 10 years old.
