A clog in the laundry center washer's drain system or a failed drain pump can prevent the washer from draining the water.
First, check the house drain for your laundry center for a clog and clear the house drain if clogged. If the house drain for the laundry center is okay, check the drain pump and drain hose for clogs and clear any clogs in the drain system. If the washer's drain system is clear, reassemble the washer and test the washer to see if the drain pump runs when activated. If the drain pump doesn't run or the pump motor runs but the pump doesn't drain out the water, then you may need to replace the drain pump.
