We cannot turn off the lock on our ceramic cooktop and it keeps on beeping.

If your ceramic cooktop model CEC70 is not turning off, there are a few steps you can take to troubleshoot the issue:
1. Check the controls: Ensure that you have properly followed the instructions to turn off the cooktop. Some models may require you to press and hold a specific button or combination of buttons to power off the cooktop. Refer to the user manual for your specific model for detailed instructions on turning it off.
2. Power cycling: Try power cycling the cooktop by turning off the power at the circuit breaker or unplugging it from the power source. Leave it unplugged or with the power off for a few minutes before plugging it back in or turning the power back on. This can sometimes help reset the controls and resolve any temporary issues.
3. Control lock: Check if the cooktop has a control lock feature that might be activated. Some models have a lock function to prevent accidental changes to the settings. Look for a button or key combination that activates or deactivates the control lock. Refer to the user manual for instructions specific to your model.
4. Contact customer support: If the issue persists, it is recommended to reach out to the manufacturer's customer support or consult a professional technician who specializes in appliance repairs. They will be able to provide further guidance or arrange for a service visit to diagnose and fix the problem.
Remember, when dealing with electrical appliances, it's always important to prioritize safety. If you encounter any unusual or potentially hazardous situations, such as smoke, sparks, or strong odors, immediately turn off the power supply and contact a professional technician for assistance.

The L indicates that the child lock feature has been enabled. This ensures that the burners do not function while you clean the cook top and that a child can't turn on any burners.

The procedure depends on your cook top model. For some induction models, to toggle the child lock feature off, press the front right burner zone display and the booster function key (circle with a solid circle inside on the right of the selector zone) simultaneously. Then press the front right burner zone display again until the L disappears from the display.
See page 23 of the manual for the Delonghi DEIND804 available here: https://www.appliancesonline.com.au/public/manuals/Delonghi-DEIND804-Induction-Cooktop-User-Manual.pdf .

For an electric ceramic cooktop DTCH808, to turn off the child lock completely, press the bottom right + in a circle and the - in a circle (in the center surrounded by 4 of the + in a circle areas) simultaneously and then release the keys. Press the - in a circle again. See page 21 of the manual here: https://www.delonghi.com/Global/InstructionManuals/EN/EN-DTCH80B_im.pdf .

I hope this helps. Please add a comment with the model of your Delonghi cook top if these instructions do not apply to your cook top.

Press and hold the keypad with the padlock icon until you hear a beep. This should be about 3 seconds. This will toggle the lock on and off. I used the documentation for the Frigidaire FGIC3067MB to check this. On this model, the lock keypad is to the left of the Keep Warm keypad. https://www.frigidaire.com/Kitchen-Appliances/Cooktops/Induction-Cooktops/FGIC3067MB/ . The manual is here: http://manuals.frigidaire.com/prodinfo_pdf/Lassomption/318205604en.pdf . The control panel is shown on page 5 and the lock function is shown on pages 6 and 9.

I hope this helps.

Hello there and welcome to fixya
This is a fairly common issue with these
These cooktops have a internal memory built into them and if they get locked they need to be reset
SO what you will need to do is to unplug the power to the cooktop and leave it sit for 1 hr and do not touch ok then after the hour is up tunr on the power to the cooktop you may hear a audiable beep sound or a click sound this is normal now press the cancel button and you should be all right from here but if not please post me back a comment and tell me what is going on and i will give you further troubleshooting steps ok ?
Best regards Mike

press and hold the power button for a min.

I have a virtvoso ceramic that showes the letter e what do I do

gud day,not all models of ceramic hob have a child lock,check it 1st ur unit if have it,if we have,touch the circle w/sign of key to lock the ceramic for ur child,to unlock touch again.u see the ligth red is on it means the lock is in ON.easy to unlock even ur child by touching the key sign,for ur safety to not use ur unit,unplug the unit if it not use.

seeming like you forget how to lock off.
keep the lock icon pressed stronger and longer,until will hear a beep,then turn it on

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........................
