The door of the washingmachine is not opening
There is an open hatch at the bottom left of the machines in which you can use e.g a sturdy key to press down the yellow lever to always open the door.
ATTENTION: This will always open the door, even if the machine is not yet finished
Can I charge up my BlueCard at Kullenhof
No, you can only charge it up via the methods provided by the STW. The closest machine to charge up your card is in the Mensa Vita.
The terminal or a machine is broken
Write the janitors what is broken at Hausmeister@kullenhof.de. You can use the other machines or the other washroom
