Before you start

What it means

The waterproof protection system has detected water escaping inside the appliance and has shut it down. The drain pump will keep running on its own until the machine is disconnected from the electricity supply.

Most likely causes

Ordered from most to least common, with what each one looks like:

Cause How likely What you would see
A hose, seal or joint within the casing has failed and water has reached the tray that houses the float high The pump keeps running even with the door open and no programme chosen
Excessive foam has escaped past the door and run down inside the casing medium Suds are visible in the cabinet, or a product not meant for dishwashers was used
The door seal has perished or is holding trapped debris, letting water track down the front medium The floor is wet at the front of the appliance and the seal feels hard or looks split
A slow seep has been filling the tray over a long period rather than a single sudden failure low Nothing obvious is wet and the machine had been working normally until the fault appeared

Fix steps

Tools needed

  1. Close the stopcock supplying the appliance. The manufacturer puts this first, before anything else is touched.

    Expected result No further water can reach the machine.

  2. Switch the appliance off, then pull the plug from the socket. Until the plug is out, the drain pump continues to run.

    Expected result The pump falls silent and the appliance is fully isolated.

  3. Open the door and check whether the cabinet is full of foam, which is a different problem from a failed hose and worth telling the engineer.

    Expected result You can describe what you found when you book the visit.

  4. Mop up any water on the floor and put towels down, but do not tilt or lay the appliance over to empty the tray inside it.

    Expected result The area is dry and safe, and no water has been moved onto parts that were dry.

  5. Contact Miele Service. The manufacturer offers no user remedy for this fault, and it should be treated as a repair booking rather than something to work through.

    Expected result A visit is arranged, and the appliance stays isolated with the water off until then.

Parts needed

No replacement parts are needed for the checks above. This fault is usually cleared without fitting anything new.

When to call a technician

Call a qualified technician for this one. The steps above are safe to carry out yourself to confirm the fault, but the repair involves work that should not be attempted without the right training and equipment.

Common questions

What does F70 mean on a Miele dishwasher?

Is this something I can fix myself?

No. This one should go to a qualified technician. You can safely carry out the first checks below to confirm the fault, but the repair itself is not a DIY job.
