bosch smi50c06gb - leak on the rear panel

[mariz]

Hi, I have a problem with a dishwasher. It started with the e15 error. At the beginning of assisted tilting of the dishwasher at an angle to the rear. But now every wash ends with an error. After removing the dishwasher I ran it and I saw that the back of leaking water and the black seal is stuffed. I pulled her and then cleaned everything but now I have a problem to put it back because it looks like that is too long
At the link below you can see the video as water leaks
Is this leak may be causing this error?
