At a glance

Code F121
What it means Ice cube maker defective (voltage fluctuation, no/low water pressure, or mechanical/electrical fault).
What you can check Power the unit down and up again if the voltage is unsteady, and check that the inlet tap is open. Low pressure, dripping valves or ice jamming the maker should go to the facility manager or a plumber.
When to call a technician If a mechanical or electrical fault inside the maker is the cause, or the checks do not clear F121, book a service visit with a technician.
  1. Unsteady voltage disrupts the system. Power the unit down, then up again.
  2. No water arrives. See whether the inlet tap is open.
  3. Low pressure at the connection. Intake valves drip, ice forms on the maker and jams it mechanically. Speak to the facility manager, a plumber, or Miele Customer Service.
  4. A mechanical or electrical fault inside the maker. Miele Customer Service is the contact.

Nearby codes

  • F120 for the voltage warning.
  • F1 for a generic technical fault.
