We should check if residue remains on clothes or in the washing machine following a cycle, the problem may have any of several causes. In that case you should make sure that you are using the machine properly—putting the right amount of soap in the load, not overloading the machine, and so forth. If it isn’t such case with the machine then up next, the chances are good that the rinse water is not getting into the drum or is not draining out properly. For this first of all, we should check the supply valves to make sure that the water supply valves that serve the supply hoses are open all the way.
Then we should check the drain hose to make sure the machine is draining fully and there isn’t any problem with drain hose (washing machine). A blockage can cause dirty rinse water to back up and remain in the drum. So whenever you run a load, watch the machine to make sure it empties completely after each wash and rinse cycle. For convenience, we should make sure that it isn’t having any problem with any other part. We should check if the cold water supply hose blocked or not? For this, we should turn off the valve to the hose, and then disconnect it from the machine. Then we should put the end into a bucket and turned the faucet back on. It should deliver a strong flow and if it doesn’t, the hose may be partially obstructed.
