Appliance Repair Questions? Ask a Technician for Answers ASAP
Is the hob, potentially in demo mode, does dE show up?
Are the pans definitely induction type? - you can check by ensuring that a magnet sticks to the base.
Also, is the pan large enough to cover the cooking zone - try different size pans.
If none of that helps please confirm the error codes.
I hope that helps, Best Regards,
Is there any protective film left on the hob?
Try cleaning it with a damp cloth and drying off.
Try turning off at the mains power for at least 1 minute then back on and try again.
If none of that works, then it does sound like the hob is faulty.
Do you require any further assistance?
If not, I hope my answer was helpful and if so a positive star rating would be much appreciated.
