Meaning
Waterproof system activated: Miele's leak protection has tripped and stopped the program.
Can I fix it?
No, call a technician
Seen on
Miele dishwashers with the Waterproof system and a code display.

F70 means Miele’s Waterproof system has reacted to a possible leak: the program stops and the drain pump starts on its own. Miele’s instructions are about making the machine safe, not fixing it: close the water valve, switch off, unplug, and contact Miele Customer Service. Guides that tell you to tilt the machine and dry the base go beyond what Miele advises.

Try this first

  1. Close the water valve (stopcock) to the dishwasher.
  2. Switch the dishwasher off and unplug it. The drain pump will stop.
  3. Contact Miele Customer Service or book a technician.

Straight away, once the water is off and the dishwasher is unplugged. Miele gives no owner remedy or reset for F70: the leak and the Waterproof system need a Miele technician.

Questions people ask

Why is the drain pump running with F70?

When the Waterproof system reacts, Miele cancels the program and switches on the drain pump. It stops once you unplug the dishwasher.

Can I reset F70 myself?

Miele doesn't give a reset for F70. Its steps are to close the water valve, switch off, unplug and contact Customer Service.

Is it safe to tilt the dishwasher to drain the base?

Miele doesn't recommend it. Leave the machine unplugged with the water off and let a technician find the leak.
