Sounds like you may have had air enter your water line from an outside source such as the water company doing work. The air will stir up any sediment in the lines and it can clog strainers in various appliances. You have a strainer in your fridge water line just before the water inlet valve on the back of the fridge. Cut the water off under the sink or wherever the cut off is and take the line off from the valve and see if it's clogged up. Clean it out if it is and if you have any trouble with the washer it might have the same problem. The hot water lines aren't usually affected because the sediment will settle in the hot water tank. You ice maker should also be affected.
