I just moved into my apartment on Friday. I hooked up my washer and dryer on Sunday and did 4 loads of laundry. I had to leave for acouple of hours and I started another load before I left. When I came home two hours later I heard water running. Like the top of the washer had been left open. But as I walked over to it the whole floor was drenched and there was like 1'1/2 of water on the kitchen floor. I looked over and turned off the water. I looked like the wash had finished its cycle but the drain hose was completely off. The water was coming out of the drain hose. So why is it doing that? I live in an apartment and I don't know who's fault it is. Plus the apartment below us is now flooded because of us. What do I do? Water is not suppose to come up the drain pipe is it?
