That picture reminds me of a Whirlpool dishwasher in a lean-to-cum-conservatory filled with boxes containing shredded newspaper. When moving the boxes, mice scarpered everywhere. Luckily, parts to resolve the dishwasher leak were no longer available.
My first encounter with a rodent however was across the terminal block behind the lower front panel of a 1990s Bosch dishwasher – I imagine its death was instantaneous.
