Most Likely Causes (Ranked)
GE dishwashers use a flexible rubber gasket around the door opening. After 5-8 years of daily closing, the gasket takes a permanent set (compression deformation) and no longer seals at the bottom corners. The bottom corners are the highest-pressure point during the wash cycle.
The wash motor seal or the spray arm bearing seal can fail, causing water to leak from underneath the tub during operation. This requires pulling the dishwasher out to diagnose.
The supply hoses and internal hoses on the GE dishwasher can loosen from vibration or deteriorate from age. Braided stainless steel supply hoses last 5-8 years; rubber hoses should be replaced every 3-5 years. A burst supply hose is the #1 cause of major home water damage.
A clogged drain line causes water to back up and overflow during the drain cycle. GE dishwashers accumulate debris (lint for washers, food for dishwashers, frost for fridges) that blocks the drain path.
Pumps, tubs, tanks, and internal plumbing in the GE dishwasher develop leaks from age, corrosion, or manufacturing defects. These leaks typically appear from underneath the appliance and aren't traceable to any external hose or connection.
