Miele Refrigerator Error Codes — Complete List

Miele built-in refrigerators rarely show error numbers, and when they do — F0 and F3 — Miele's own support pages simply say it's a technical fault you can't remedy and to book service. The two places an owner genuinely has options are the F121 ice-maker code (check the water supply before calling) and the red water-filter indicator (replace the filter — normal maintenance).

• F0 F0 on a Miele refrigerator is Miele's 'technical fault' code — nothing you can fix at home, with only a single reboot worth trying first.
• F3 F3 is another Miele refrigerator 'technical fault' code — not owner-serviceable, with a single reset the only step worth trying at home.
• F121 F121 tells you the ice maker is struggling or failing — and Miele's own page says check the water supply and pressure before assuming the ice maker is dead.
• Water filter indicator red (Water filter light) The red water-filter indicator is the fridge reminding you the filter cartridge has expired — normal maintenance you do yourself with a replacement cartridge.
