Dishwasher drain overflow

2 posts in this topic

I have a dishwasher drain line that goes into its own vented drain pipe under the sink.  The line goes up high like it should. Starting just recently, often (not always) we get a slight overflow from the vent portion of the the pipe ( the vent comes out of the side of the pipe at a slight angle), and you can hear the pipe filling up as the dishwasher drains. The pipe does not appear to be clogged at the trap, it has been snaked and the snake didn't even have residue on it, and we used Draino. The dishwasher is seven years old, we are the only owners, and the dishes have always gone in clean (no food debris). Any idea what the problem could be?

The drain is not draining the water fast enough, something is clogging the drain line, is the only thing that could be causing this to overflow.
