Why is sink water backing up into dishwasher?
Question by coupe: Why is sink water backing up into dishwasher?
I have a double sink, with one having a garbage disposal. Every few days I notice a bad smell in the kitchen. When I open the dishwasher (a Maytag Jetclean-about 5yrs old), I discover that sink water has backed up into it. I have tried drain cleaner and snake. No luck so far. Ideas?
