Defective GE Dishwasher

Recently, we were assigned to a case where water damage had occurred inside a residential kitchen.  In this case, the dishwasher was placed in operation and allowed to run while the homeowner was away.  Upon returning, the homeowner discovered that their kitchen and part of their family room had been flooded with water.  After recovering the dishwasher and conducting an examination, it was discovered that the gasket between the drain and tub housing had failed.  The failure resulted in massive water leakage.  The photographs shown below illustrate how water was pouring out of the wash tub housing.  It should be noted that the dishwasher was approximately four years old when the incident occurred.  Dishwashers typically do not experience water leakage at the drain and gaskets last for the lifetime of the appliance.  In this case, the manufacturer used three rotating locks to hold the drain assembly in place while pressing down on the gasket to maintain a seal between the drain and housing.  This particular problem applies to General Electric dishwasher model # GDF520PSJ2SS.  It is recommended that owners with this dishwasher should not leave this appliance in operation with no one in attendance but, instead carefully monitor the operation.  At the first sign of water leakage, turn the dishwasher off.  Doing so will deenergize the water control valve and stop the flow of water into the tub.  However, water will continue to flow out of the area of leakage until the tub is completely drained.  It will become necessary to remove the dishwasher from its position, usually beneath a countertop, in order to dry the floor.  At this point, the homeowner will have a decision to make: have the dishwasher repaired or replace the appliance.  Remember that if the appliance is repaired, because of the design, the appliance will most likely leak again.
