Leave it to the manufacturer to blame it on the quality of the water. They'll never admit that the real problem is the fact that they designed the machine to rinse a full load of clothes on a small water level setting. This is the same machine that was posted on here recently. She needs to address Whirlpool with the fact that it is NOT her water since her previous washer rinsed with no problem. You can't have rinse water levels in a top loading machine, that is better designed for full water usage. If the rinse cycle is going to be that low, then they should at least have a 30 second spin spray between the wash and rinse cycles when the washer has reached full spin speed. Not a total solution to the problem, but I would think the results would be a bit better than they are. And with that spin spray and low level rinse, you would still be saving water compared to a high water level rinse, that is, if you are really concerned with water conservation.
