For the Candy CH642B cooktop: LOCKING BUTTON OPERATION The locking function prevents the children from starting the hob. It is also used for cleaning the control strip as the controls can be locked without the hob being on. To lock the hob : - Press the on/off button - Press simultaneously " - " button and " + " button of the front right zone (CH 633 front left zone), and then press again on the " + " button of this zone. When the hob is locked, the locking indicator " L " is displayed on all zones for 20 seconds.

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?
[submitting this as 'post solution' but there is no button for 'say you have the same problem'!]
i called up AEG customer service, and they said: Press the '-' and bottom right '+' sign and this should take off the childlock. So it looks like there manual was correct. It seems like in some cases you need to do this, or the method suggested in the other post
hi im gerbee my suggestion is replace the pcv control wat brand u have,always also in philipines the electric hob is so very sensitive,the pcv cotrol is not repairable.or next time u by a new one gas cooktop more ok compare to electric ceramic hob, or use electric ceramic hob w/knob control compare to sensor type,i think the part of the sensor or pcv control is so very expensive,that why i buy an another one.dont try to repair more difficult to com.tnx
Great.. finally. i manage find from solution from user guide.. L is Locked. below is the instruction. will check out tonight.
The locking function holds the current settings, or prevents anyone
from starting the hob. It is also used for cleaning the control strip
as the controls can be locked without the hob being on.
To lock the hob :
-Press the on/off button .
-Press simultaneously " - " button and " + " button of the front
right zone (PVD 633 front left zone), and then press again on
the " + " button of this zone. The hob is locked, the locking
indicator " L " is displayed on all zones for 20 seconds.

on the " - " button of this zone.
The hob is unlocked.
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........................
I have a Stoves 900 CTH with the same problem. Its been like it for about 6 months and we're still able to get it going eventually.
If you turn the power on at the mains and leave it beeping for about 2 hrs then press the power on touch button. You should see all the "0."s flashing. When the flashing and beeping goes slow try pressing one of the hob buttons alot until the little dot illuminates next to the 0 then quickly lit the + button.
It sometimes works after 5 mins but other times it takes 20-30mins and is a real pain in the ****.
I did ring Stoves a while back and they quoted me £190 for the pcb but I hardly use it so just lived with it as it is but I finally had enough tonight and done a web search which turned up this thread.
I've just pulled it to bits to see if I could locate this "C17" but not 100% sure what I'm looking for.
Is it the big silver thing in the center with 5B RVJ on it?
