Have a baumatic ceramic hob displayin letter 'L'

Got the same problem, and remembered I've kept the manual book
L means locked. I dont know how Ive managed to do this as well

Anyway it says:

Cancelling the key lock
After switching ON the control the child safety feature can be deactivated. Here it is necessary to simultaneously operate the front right cooking-zone-select-key and the MINUS-key and then operate the MINUS-key alone. If all steps hae been carried out in the right order within 10seconds the key lock gets cancelled and the control is OFF. Otherwise the input will be considered incomplete, the control remains locked and switches-OFF after 20 seconds.

After a renewed switching-ON/OFF key all displays show 0", the display dots are blinking and the control is ready for ooking. If a cooking zone is "hot", "H" will be displayed instead of the static 0".


Followed their instructions & still not worked. ,I am still confused and baffled after these instructions........................

If all displays show 'L' then the hob is child-locked. It will not heat up or respond to other buttons and will automatically turn off within seconds.

To turn the hob on through the child lock, press 'On', and then within 10 seconds press both the bottom-right + and the - symbols together. It should turn on. After this you will need to heat at least one of the hobs to keep it turned on, as the cooker returns to standby if not used.

To turn off the child lock (this is the bit you want, I think!) you need to press 'On', then press the + and - buttons together within 10 seconds as described above .. and THEN press the - button one more time.

Hope this helps :)

Thank you, guys! Tried to press the lower right button together with minus - it workes!!! However has already eaten some sheet on dinner... :/
