I was helping my friend cater for a smallish group at a renovated 17th C Finnish manor. The kitchen had been done up with a mish-mash of "old" fixtures and new swanky gear. We couldn't figure out how to open the concealed dishwasher. We pushed at cabinet panels, pressed a disembodied button we found under the sink, we put the button against the panels... we were stumped.

The dishwasher door opens automatically when the cabinet panel is knocked on three times, like a fucking fairy tale gremlin.
