Reading the dishwasher display

A dishwasher reports its fault in the display window, or by blinking a cycle light a set number of times with a pause between groups. Count the blinks and pauses before opening the door. Miele displays an F followed by a number and often a text hint in your language.

Miele reports faults as F-numbers on dishwashers and washers and expects many of them to be handled by a service technician. Plenty of the entries here are first checks you can safely do before booking a visit. The codes apply to model numbers such as G 4228 SCU, G 7156 SCVi and W1 Classic WWF060; check the label on your unit to confirm yours.

What causes F70

How to fix it

  1. Cancel the cycle and make sure the hot and cold supply valves behind the machine are fully open.
  2. Turn off the water, disconnect the fill hose and rinse the small filter screen at the valve inlet to clear sediment.
  3. Measure the coil resistance with the machine unplugged.
  4. Inspect the hose for kinks and test another faucet in the home to confirm pressure is normal.
  5. Reconnect, restore power and start a short cycle while listening for the valve clicking and water running in.
  6. If water still fails to arrive (or never stops), measure the valve coil with a multimeter and replace the inlet valve if it is out of range.

Questions

What does error F70 mean on a Miele dishwasher?

The water-protection valve or inlet detected an error. Exact behavior can vary by model and software version; confirm against your own manual.

Can I keep using my dishwasher while F70 is showing?

Only briefly. A machine that cannot fill correctly will wash poorly and, if the valve sticks open, can overflow, so shut the water off at the wall when it is idle.

How do I clear F70, and can I fix it myself?

Cancel the program, switch the appliance off and leave it unplugged (or the breaker off) for about five minutes, then restart. The code only stays cleared if the underlying problem is fixed, so work through the steps above. Parts here involve electronics, heating or sealed components, so consider a qualified technician if the basic checks do not clear it.
