While running the dishwasher water leaks heavily out of the bottom front. I replaced the seal to no effect. I then noted that while the dishwasher is running there is a lot of standing water in the bottom which is what is running out during operation. When I place the operation in final rinse the water will drain out normally which tells there shouldn't be a clog. I have had this dishwasher for many years. Is it possible the pump is just not getting rid of the water as it should?
