I've been looking for a 6 series service manual and that is not available either. I did find a 5 series guide and from that, I see that the configuration in the sump on the 6 is different than the 5. The 6 is closer to the 7 series than the 5, plus the programs are different so the manual doesn't help much. As for programming the manual says to refer to a separate document but does not give its name.
My model has the touch buttons and display screen on the top of the door and no display screen on the front, and no start button either, so I haven't been able to figure out any sequence to use to enter programming mode. Henne, I've done all of my activity with the door open are you saying I should press some keys and then close the door, then open it again?
Rod good luck with the search and please let us know if you find it.
