Re: Condensation on cabinet.
I’m not familiar with the model but, basically, if one of the hot return pipes runs there (especially in a cold environment) then yes, you will get some condensation externally. Usually it’s not too much of a concern.
It’s more common to see this around the door in the UK as it is the anti-condensate line that stops condensation forming in higher ambients. It has the opposite effect when it gets too cold.
Unless one of the Bosch guys knows any different it may be worth having it checked or asking Bosch’s technical if you can get a hold of them.
