How to fix Miele Water inlet fault / Water intake light flashing

  1. Turn the supply valve fully on

    Check the shutoff for the dishwasher first. A half-open valve after plumbing work is a classic cause.

  2. Clean the filter in the hose connection

    With the dishwasher unplugged and the valve closed, unscrew the inlet hose, pull out the little plastic filter, rinse it and refit it with its seal. Keep the hose's plastic valve housing out of water.

  3. Get the kinks out

    Straighten any bend or loop in the inlet hose and keep an eye on that spot for a few days.

When to call a technician

If water pressure in the house is normal and the message keeps appearing, book a Miele technician.
