Bad smell This is more of a general question. When I run the dishwasher there is a bad smell as it fills with water. It comes out of the sink/garbage disposal. I have cleaned out the line that comes from the garbage disposal to the drain and that doesn't stop the smell. Is there a line that needs to be cleaned from the dishwasher to the sink or how can I fix this issue?

It sounds like your dishwasher does not have an air gap. Newer dishwashers come with an air gap installed, but they can be taken out. A quick fix for this is to:

Check the drain line under the kitchen sink. The drain line is supposed to run from the bottom of the cabinet, and run as high in the cabinet as you can get, (up to the bottom of the counter top) then connect the drain. This is called an air gap, and helps keep a little water in the drain line, which will prevent sewer gases from entering your dishwasher, and garbage disposal.

Most problems with smells in Bosh Dishwashers come from failure to have the 20" rise in the drain line between the dishwasher and the drain as the installation manual requires.

My factory installer failed to do this. After looking at the installation manual, which shows a 20" rise, I used electrical ties to hold the drain line 20 inches above the floor. The smell which was causing us to run the rinse cycle every day to get rid of the smell has not been back in five days.

The smell is almost certainly from the garbage disposal unit - dreadful devices! bset solution is to plumb in drain elsewhere. this is a fairly common problem
