Miele Washing Machine F11 Error: Meaning, Causes & Safe Checks

F11 Check carefully Safe checks first

Quick answer

Miele F11 means the drain is restricted. Miele’s checks are that the end of the drain hose isn’t higher than 1 metre, the hose has no kinks or loops, and the drain filters and pump aren’t blocked. Let hot water cool first. If F11 continues after cleaning, contact Miele or book a repair.

What F11 means on a Miele washing machine

The drain is restricted: the machine can’t pump the water away properly.

Applies to: Miele washing machines sold in the UK.

What you might notice

Likely causes

What you can safely check yourself

Stop and call a qualified engineer if:
  • A hose is split, bulging, cracked or leaking at the connection. Stop using the appliance until the hose is replaced.
  • The code or problem comes back after you’ve done the safe checks on this page.
  • The next step would mean removing a cover or panel, or working on the pump, valves, heater, motor, door lock or wiring. That is a job for a qualified engineer.
  • Water is leaking from inside the appliance or is near the plug or socket. Don’t touch the plug with wet hands or while standing in water. Switch off at the consumer unit instead.
  • The appliance is still under warranty. Contact the manufacturer first, because DIY work can affect your cover.

Work through these in order. Stop as soon as one of the signs above applies.

Check the drain hose position and for kinks Take care

Before you start
  • Switch off and unplug the appliance at the wall socket before you touch hoses, filters or the back of the machine. Make sure your hands and the plug area are dry.
  • The appliance is heavy. Pull it out slowly, ideally with help, and don’t strain the hoses or the cable.
Drain hose height and standpipe Outlet height min–max: see your manual Don’t push the hose in too far it can siphon or block No kinks or loops
Drain hose height and standpipe. Positions vary by model — check your manual.
  1. Check the drain hose behind the machine is not kinked, twisted or squashed against the wall.
  2. Check how far the hose goes into the standpipe or sink trap. Pushed in too far, it can siphon or block.
  3. Check the height of the hose outlet against your manual. Manufacturers give a minimum and maximum height above the floor or the machine base.
  4. If the hose has been extended, check the joint. Extensions narrow the flow and make blockages more likely.

For this fault: Miele: the maximum delivery head is 1 metre. If you’ve straightened a kink, keep an eye on that spot for a while, as the plastic can weaken and tear.

Clean the drain pump filter Take care

Before you start
  • Switch off and unplug the appliance at the wall socket before you touch hoses, filters or the back of the machine. Make sure your hands and the plug area are dry.
  • Water inside can be hot after a hot wash. Wait for it to cool before opening a filter.
  • Expect water to come out. Put towels and a shallow tray or baking dish down first.
  • Never force a locked door, a stuck filter cap or a seized part. Forcing it usually causes more damage.

Where the drain pump filter usually is. Positions vary by model — check your manual.
  1. Find the small flap at the bottom front of the machine. Your manual shows the exact location and whether there is a small emergency drain hose.
  2. With towels and a tray in place, release the water slowly, using the emergency hose if there is one, or by turning the filter cap a little at a time. Expect more water than you think, and empty the tray as often as you need to.
  3. When the water has stopped, unscrew the filter fully and remove fluff, coins, hair grips and other debris. Rinse it under the tap.
  4. Look into the opening to check the pump blade can turn freely. If you can see it, manufacturers suggest turning it gently with a pencil, never with your fingers.
  5. Refit the filter firmly in its locked position and close the flap. Check for drips the next time the machine runs.

For this fault: Miele: unscrew the drain filters slowly to let the water out, tightening them again to pause the flow. Some models have two filters, and each must go back on its own side and be screwed tight.

Don’t reach in with fingers past the filter opening.

Don’t open the filter while the machine is running or the water is hot.

When to call an engineer

If the checks above don’t clear F11, or any of the stop signs apply, contact Miele or a qualified appliance engineer. Have the model and serial number from the rating label ready, and start with Miele UK support.

Repair or replace?

Most F11 cases are cleared by the safe checks above. If they don’t help, the remaining causes are parts an engineer has to diagnose. We don’t publish repair prices because they vary by area, part and model.
