Kathleen,

You will want to pull the drain pump on the unit and check to make sure that the flapper is still attached. If the flapper is not attached and is not there then you would want to replace the drain pump. This flapper keeps water from flowing back into the unit. The part number for the drain pump is WP6-917641.
