Dear Glenn: My house is about 3 years old. My kitchen sink would fill with water about half way when my dishwasher was draining and I would turn on my garbage disposer to take the water down. Now when we use the dishwasher, it does not drain at all. Could you please help?

Gary, Ferndale

Dear Gary: A garbage disposer is never supposed to run at the same time as the dishwasher. You may well have plugged the dishwasher drain. It's time to call a plumber.
