To remove the water filter on the Whirlpool model WRF540CWHB00, locate the filter compartment in the refrigerator. Turn the filter 90 degrees counterclockwise to unlock it. Pull the filter straight out. After removing it, you can install a new filter by aligning it with the compartment, pushing it in, and turning it 90 degrees clockwise until it locks into place. Make sure to reset the filter indicator light if your model has one.
