Hi, I suspect that it could probably be that something is lodged in the drain pump. The pump has a trap that collects foreign objects and will wash down your drain line. You will need to drain out the water from your tub with a vacuum and access the washer to unplug it by removing the lower kick panel. Check the drain line coming to the pump by feeling it for any signs of clogging. You will need to screw off the end of the line to clear up the clogging. It should drain fine after that :)
