I have a bosch schott ceran model 9000324865. It appears that the hob has locked up as a red key has lit up. Can anyone help me to turn of this lock? I think it came on as the kids unloaded the food shop onto the work top and this is probably a mechanism to prevent the hob getting hot, however i have no manuel to help

Very specialised high tech tops need engineers to fix. It is likely to be the power board.

Question edited for clarity.
Question moved to Schott Ceran category.

Replacement knobs, but it should go by the numerical model number in the search query as well.

make model specs will get you somewhere like here

Schott Cerans is the maker of the glass not the model number.

Possible failed part that needs to be replaced according to the discussion below:

My schott ceran hob is not working and showing er26 Just

The reference to Schott is the maker of the ceramic glass. The label identifying which brand and model number will be located on the base of the cooktop.

If the cooktop itself randomly locks itself, it would most likely be related to the touch panel and the sensor plate that would require replacement.

The lock would be the child lock, and usually holding down the key symbols for a period of 5 secs should remove the lock.

Try to do a search on the Internet, something like: Manual Bosch + your model number. I have usually had good luck finding a free download. Sometimes there are downloads also available directly on the manufacturer's website as well.

SAve my life! Thank you so much!

Pl click helped if helped.

Hi,

If you have an illuminated red key symbol on the cooktop, press down where the illuminated red key is, for about 5 seconds. This method works on many Schott Ceran / Miele cooktops including the KM443 listed above.

If this doesn't work, please let me know the correct model number.

Hope this helps.

We have this exact same problem, and I've not managed to track down a manual (we rent and the landlord is on holiday).
I've tried holding down all buttons for a time, combinations of buttons, and turning it off at the mains, but no joy.

Did you ever solve this?
