Hi,Welcome to Just Answer, My name isXXXXX will be helping you with your appliance issue today.
theres a short in the board thats sensing the probe when its not plugged in. the factory warranty covers this for 12 months I would get in touch Bosch right away before the warranty runs out, I would not play with it at all or you will void the warranty,
heres the company info which you probably already;ready have but here it is anyway,
