I bought a used Kenmore Dishwasher 665-16712000 9 months ago and it has worked great until now. The water miser light just keeps flashing and it won't start any cycle. If I hit the cancel/drain button the water miser light, the quick dry light, and the cancel/drain light all flash. Eventually they will stop except the water miser light. I've tried turning the power off but that doesn't work. Any suggestions would be greatly appreciated.
