For a long time I didn't realise that the Miele had fans. I usually run machines in 'set and forget' mode: I turn it on and then do other stuff. I was walking past the Miele and felt some warm air. I stopped to investigate and found it was coming (extremely quietly) from a vent on the top left of the door. I had thought, prior to that, that it was just a passive vent. (Just in case you reckon that I think that the Miele machines are perfect, my indicator lights for 'empty' rinse-aid and salt don't turn off. I'll get them fixed when I next need a serviceman. And the automatic anti-flood cut-out switch has had me thinking that the machine had died when it just needed some extra cleaning.)
