Hello,
I think I understand what you mean now. When your washer fills it drains out at the same time? If this is the case, you have to make sure your drain hose is at least 32 inches high so the water doesn't siphon out the hose and stays in the tub. Also, don't seal the end of the drain hose to the plumbing with anything such as duct tape, etc. or you will have the same problem. Hope this helps.
