Dishwasher Does Not Drain - GE Appliances
New dishwashers come with a white corrugated drain hose, which should be used. Re-using old, worn out drain hoses may promote kinking and blockage. Make sure the kitchen sink drain is not clogged. If a disposer is installed, run the disposer to clear the drain system. Do not put hands into the garbage disposer, as serious injury could result.
