Press the "Filter Reset" button on the lower left of the control console and hold it until the filter light turns green, if your Daewoo has a "Filter Reset" button
Find the “Ice Maker Lock” button on the lower right-side corner of the control panel, if your model does not have the "Filter Reset" button. Locate the “Lock” button on the right of the filter change lights. Both buttons are clearly marked.
Press both the “Ice Maker Lock” button and the “Lock” button at the same time and hold them.
Allow three seconds to pass, and release the buttons when the filter light changes to green indicating the filter is reset.
