To be safe, it is best to wait at least 24 hours. If the icemaker was installed but the water line was not added until later, once the water and icemaker is turned on the icemaker will cycle within a few minutes and fill and process its first cubes in about 1 1/2 hours.

How long does it take for ice maker to work?

After you have installed your refrigerator it will take 6 to 12 hours for the fridge-freezers ice maker to produce ice. You should throw away the first three batches of ice cubes that the ice maker dispenses (approximately 30 cubes) to ensure that all the ice cubes you use are made from clean water.
