Bosch dishwasher back panel seal is corroded.

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.

To clear the drain in a few easy steps; find where the outlet hose connects into your house drain system, disconnect it and then see if the machine will drain into a bucket/tray. Try it both by gravity (if you can get the hose below the water level)and with the machine on if not. This will tell you if the blockage is in the house drain not the machine. If the house drain is clear, see if you can disconnect the drain hose from the machine end and check it isn't blocked.if this is not removable, try poking a bit of wire or similar down it, being careful not to go past where it enters the machine (measure your bit of wire against the outside of the hose first). As Joe says, if you are sure the accessible filters and everything you can get to easily are clear, a garden hose in the hole will possibly clear the blockage if you can get a bit of pressure - often the easiest way is to hold a rag tightly around the end of the hose and the hole you are trying to get water through. (Note you will get wet - be very careful of electical sockets etc). If this doesn't seem to clear the blockage then the pump is either faulty, or not recieving instructions from the control board to work (more likely, although you would expect an error message). Hope this helps, if you wish to change Joe's rating you can just by rating the advice again. Good luck :)

Hi have you adjusted the door striker on the top part of the dishwasher? This is the part that the main door latches onto and can be adjusted in or out!

Check the screws on the pump cover under the lower spray arm (the spray arm is easy to remove, the screws are torx - maybe a torx 10 or 15, so a regular screwdriver wont work). They come loose on ours every 6-12 months and spray water at the door, causing it to leak all over our wood floor. I routinely tighten those screws now before they come loose enough to cause the problem.
Replacing the door seal doesn't help - if you look at it closely the bottom of the door doesn't seal against anything, it just overlaps the front of the tub so water sprayed hard against the front (from a leaking gasket) can go under the door and up and over the tub front, making it look like a door seal problem.

Check the door seal. To do this, make sure the door and the rubber gasket is complete dry. Apply a liberal amount of liquid detergent around the rubber gasket. Then close the door. Open the door and look for the liquid detergent to transfer onto the door. If there is a gap, then you will need to replace the door seal.
