A couple months ago, I installed a new dishwasher in my kitchen. The old dishwasher was emitting a foul smell from time to time. Due to the smell and the overall need to upgrade old appliances, I installed a new Kenmore dishwasher. The smell hasn't gone away.
The drain hose doesn't empty into the garbage disposal. It empties directly into the drain. The drain hose feeds up towards the bottom side of the countertop before emptying into drain. I had two thoughts to what could be causing this:
1. There drain has food remnants rotting and that water is backing up into the dishwasher.
2. The drain hose has a little too much slack and that dirty water is sitting in there causing the smell.
It doesn't smell horrible all the time, which seems odd also. Anybody have some advice on the issue, and what the best way to fix it is?
