Ge dishwasher bottom door seal leaking - GE Dishwashers

SOURCE: dishwasher leaking

There is a front door seal that may be the issue. It seals along the door sides/top and continues under the door to seal the bottom surface when closed. Mine pulled out of the seal channel under the open door where you can't see it without a small mirror. The seal took a "fixed set" out of the channel so now it will not stay put. It requires replacement.
Hope this helps.

SOURCE: door still leaks after replacing bottom seal

the bottom seal isn't actually a seal, rather it serves as a splashguard. I had the same problem with the same model and started by replacing what I thought was a seal located at the bottom of the door.
Check if the screws on the top half of the pump (located under the lower spray arm which needs removed first) have become loose. The screws were barely in the threads which caused a stream of water towards the door and leaked between the splashguard and bottom edge of the tub and onto the floor.

I had the same problem in 2004, lots of Bosch trained repair techs, calls to Bosch, and the appliance dealer we purchased it from with no answers. Our kitchen cabinet bases were ruined by the flooding that occured. After months of trying to get help I insisted on speaking to a supervisor that told me it was my fault for putting a flexible cutting board on the right side a blocking the vent. I told her that no where in the manual did it mention this issue and none of their trained techs were aware of this flaw in their design. When I asked about getting my cabinets repaired she said that was not an option. When I mentioned possible legal action her response was "good luck with that". Here it is 2009 and they recently called about a possible fire hazard recall for the control panel. The Bosch trained tech that came out to complete the repair knew nothing about the vent/flooding issue.

The bushings for the lower spray are are probably worn causing the lower spray arm to wobble. This sets up a wave pattern in the water at the bottom of the dishwasher and the waves cause the leak.
