Miele Refrigerator F121 Error Code
What it means
The ice maker has failed; Miele lists voltage fluctuation, loss of water supply/low water pressure, leaking intake valves, or a mechanical/electrical ice-maker fault as possible causes.
Try this first
- Switch the refrigeration appliance off and back on once.
- Check that the water supply to the ice maker is open.
- If water pressure is low or the intake valves leak/drip, contact the facility manager, a plumber, or Miele Service because icing can mechanically block the ice maker.
- If the ice maker has a mechanical or electrical fault, contact Miele Service.
