whirlpool dishwasher washes but won't drain. took the drain hose off, and drain hose is clear. also water in the dishwasher drains out of the tub. found a small ball and a plastic bracket in the drain water, i assume this is art of the check valve and can be replaced bach in the check valve. have not taken off the check valve yet. this is our winter home--unit was working fine when i left four month ago. Ive taken off the spray arm looking for obstructions--looks clean and impeller turns freely. I'd appreciate any help'
thanks
