Remove the refrigerator water filter
The U.S. Environmental Protection Agency refers to the built-in refrigerator water filter as a "point of use" device. These filters are similar to the water tank, countertop and faucet filters in many kitchens across the country. The agency pointed out that point-of-use filters can effectively remove most water contaminants that cause undesirable taste and odor. If your ice cubes or glass of water look strange and unpleasant to your taste buds, removing and replacing the water filter may restore everything to its original state.

Expired water filter
The filtered particles and chemical substances remain in the filter cartridge and eventually pile up, reducing the filtration efficiency. Some refrigerator manufacturers recommend that the owner replace the filter cartridge every six months to maintain the best filtering quality. Modern high-tech refrigerators may automatically turn on the "water filter status" light after 400 to 500 gallons of water has passed through the water filter assembly. Refrigerator water filter cartridges are expensive, and discarding some newer filter cartridges may waste money and effort. Please refer to your instruction manual for the exact expiration date.

Obtain replacement ink cartridges
Refrigerator water filter cartridges usually have the designated alphanumeric part number listed in the instruction manual, such as "edr2rxd1". Some large electrical appliance manufacturers recommend ordering replacement water filters directly from the company's online store, or calling the customer service department. Alternatively, a third-party company can manufacture "universal" or "universal" refrigerator water filter elements, which may be cheaper and have the same effect as brand filters. Find universal ink cartridges at your local home improvement store or online retailer. No matter which filter you choose, make sure it is the correct part number to avoid damage to the water filter housing due to the use of an inappropriate filter element.

Disassembly of the water filter
Press the "off" button of the ice maker to deactivate ice making. This can be a button on the control panel outside the door, or a button on the ice maker assembly located on the ceiling of the freezer compartment. This can prevent the ice maker components from pumping new tap water when replacing the filter, but be aware that there will be excess water and dripping during the replacement process. Press the "filter release" button or similar button above the filter cartridge to release the housing from the water filter assembly. Pull out the expired ink cartridge and throw it in the trash can.

Place a new water filter
Carefully open the water filter replacement package, making sure that you have not broken the inlet and outlet connectors at the end of the filter element. Remove the protective cover from the connector. Slide the filter element in and fix it in place in the filter housing. You may hear a series of clicks. Carefully push the water filter housing into and close the assembly. Turn on the ice maker again. If applicable, test the water output of the water dispenser outside the door; look for leaks around the water filter assembly in the cabin. You may also have to reset the "Water Filter Status" indicator light according to the manufacturer's instructions.
