Re: Bosch SGV57T03GB wash times extend to 144min
Thank you very much to the various extremely helpful people who have contributed to this post. I have followed the instructions and hopefully I have a working machine again.
It looks to me like the rogue chamber full of dirt at the top left of the matrix is a pressure relief channel for the main water fill. It has a small water entrance on the leftmost side about three inches from the top of the U bend and then has a ‘maze’ to prevent too much flow before it reaches a vent right at the top. This is a poor design as the maze traps dirt and crud. I suspect that mine is completely blocked now and would not function. However, I doubt that it contributes to smells or problems.
If you wanted to clean it out you would have remove the matrix completely and be very patient with a high pressure hose, some pipe cleaners and bleach. Probably not worth it.
