Wasteful

Your washer DRAIN HOSE is causing a siphoning condition. Your washing machine drain hose is pushed way too far into the stand pipe in the wall. There needs to be an air gap and by having the drain pipe pushed too far there is no air gap. This creates a vacuum or siphoning affect and the water is pulled out of the washer as it fills with water. What you need to do is pull the drain hose out of the stand pipe and put it back in making sure it is not in the wall too far or too deep. There needs to be a bend at the apex of the drain hose. It needs to be above the height of the wash tub. Once you have the drain pipe or hose in the exact position you need it to be in to not cause siphoning, tie the drain hose to the water fill hoses with a plastic zip tie so it can't fall back down deep or pull out.
