Moisture condensing on surfaces is detrimental to kitchen furniture. So, keep the dishwasher closed for half an hour after the end of the program before removing the dishes. This allows the water vapour to run down the inside walls of the machine rather than escaping into the room. 

The dishwasher should then be opened wide and not just with a narrow gap in order to prevent water damage. It is essential to ensure that the vent plate has been screwed or glued in place below the worktop in the dishwasher area. The vent plate is normally supplied with the dishwasher. Be sure also to read the dishwasher manufacturer’s instructions.
