the key sign shows that the child lock is engaged. to unlock, usually you push and hold the lock button for a few seconds. the correct button is usually a dual function and so marked. if you need more help, go to manualsonline.com and look up your model number for your manual. good luck

Contact Bosch website and ask customer services if they have had this problem before. It may be subject to recall if there is a fault. Also have a word with the installer. If there is any leakage of radiation it MUST be stopped.

sounds like a power surge occurred when power came on and blew out something on the main board. Try looking up the model and model number online and you can find the owners manual then look up the section that tells what the code means. Try unplugging it and leave unplugged for an hour. then plug it in and see if this helps.

Hi,

Can you provide a model number for your oven. Is it a single oven or double ? Wall oven or free standing range ?(conventional with cooking surface)

Unfortunately the error codes for Bosch are different depending on the model of the unit.

Thank you, I`ll look for your reply.

i am not aware of a bosch oven that locks the top door usually only main oven will lock if self clean pyro oven,the small oven never has this feature sounds more like a hinge problem check nothing is fouling the lower part of the oven door.

not separately programmable
