Product review (4 stars): window stains after first self-clean
Repost from model 7052 but also relates here:  I'm sorry I ignored the other poor reviews and went ahead with my purchase. All features are working satisfactorily for me but I've experienced something no one else has mentioned so wish to warn you. We just performed our first self-clean function of the oven after a couple months of light use. After the cleaning was completed, we found a stain covering the upper left quarter of the window; the stain was located between the panes of glass and not accessible to us. The service tech and Bosch customer service both explain that the oven is vented through the panes of glass and smoke from cleaning can deposit. Bosch is unwilling to admit this is a huge design defect. The tech says he can clean the stain by removing the door and disassembling it for about $120. All Bosch ranges apparently have this design so I highly recommend staying away from all of them or at least get a guarantee this won't happen to you and that they will guarantee to replace the door forever if it does.

April 2014 update:  I posted a question regarding my problem on Bosch's FaceBook page and received an immediate response from Bosch. He reviewed my pictures with his engineers and determined the glass was flawed when installed at the factory. Both the tech I had previously worked with as well as Bosch's own Customer Service rep had deceived me. A different service group was given direction to replace the glass under warranty.
