Washing machines do their job by tapping into your home's water supply. They pull this water--both hot and cold--into the machine through the hoses attached at the back. Inside these hoses are two hose filters that are used to strain out the sand, silt and other impurities that can sometimes make their way into a municipal water supply. If you find that your washing machine isn't filling up as much as it used to, it's time to clean out your washing machine hose filter.
Unplug the washing machine from the wall.
Turn off the water to the washing machine. The water valves are usually located directly behind the machine. Twist them clockwise to shut off the water.
Move the washing machine away from the wall. Give yourself enough room to get back there and work comfortably, but at the same time take caution that you don't stretch out the hoses.
Use the pair of pliers to unscrew first the hot, then the cold water hoses from the washer. Keep the towel handy, as some water will spill out.
Use a pair of needle nose pliers to remove the filter screens from inside the hose inlet. They look like small round pieces of window screen.
Wash the filters out in a mild solution of water and a few drops of liquid dish detergent. If they're ripped or haven't been changed in a couple of years, replace them with new ones.
Insert the filters back into the washing machine hose inlets.
Reattach the washing machine hoses. Turn on the water and check for leaks. Tighten if necessary. When satisfied, push the washer back into place.
Plug the washer back in. Run a test batch of laundry to make sure that the machine is filling properly.
If you have hard water in your area and your machine's filters clog frequently, you should investigate hooking up a water softener to your home system.
Use caution when working around water and electricity.
