I was suffering from the same electronic problem, after I took some shots in the tropical greenhouse in the botanical gardens in munich. I dried the cam and put it in to my backpack, with some small drying bags (small bags often added to prevent moisture). Condensating water (outside -10°C) corroded the electronic inside.
The back dial wheel, the info button, the menu button, and the right upper buttons did not work anymore.
It was not easy to convince the Canon Service partner that this issue is under guarantee. They just did it, because there were no water drops inside.
The technican there told me, that the 6Ds back is weakly water seald. In their experience just the 7D, 5D,1D are sufficently water sealed.
The funny thing is, that my old 60D never had any problem when I annually stayed inside the tropical greenhouse for hours.
Maybe, the Maerz GmbH in Berlin is quite as fair as the Service Center where I sent my Cam.
