My washing machine is draining water into the kitchen sink and flooding it, started with a little now it is full on flooding. When I stop the washing machine the water seems to drain back into the wash machine! What the Heck! Any suggestions, Ideas, resolutions, info would be greatly appreciated!

You have a partial downstream from, the kitchen. The solution would be to msnake the drain from the kitchen roof vent. Rent a sewer machine,(see image) take it on the roof and put out enough cable to reach the base and 30 feet more. Test by cycling the washer. Good luck, Tom
