This article explains how to reset the water filter light on the Miele refrigerator after replacing the water filter. Depending on your water usage, the filter should be replaced approximately every six months. The filter replacement notification occurs in two stages.

Stage 1: After 23 weeks of runtime or 665 gallons (2520 liters) of water the filter icon in the display will turn red. 

Stage 2: If the filter is not replaced, the filter icon will blink after 26 weeks or 739 gallons (2800 liters) of water.

You can confirm Filter replacement in a few different ways:

Easy Way: Press and hold the Thermometer and the Filter touchpad or the freezer’s Up and On/Off touchpad for approximately five seconds (mostly on new models).

Using Customer Service Mode:

• Switch the freezer ON.
