Thank you for that information,
Please try one thing for me so I can be sure of the problem.
Please switch off the hob at the mains for 30 full minutes. Then you can turn it back on. If the processor in the main control board simply glitched as they can, this will solve the issue.
If not please let me know. And we will go from there;-)
In any case, I will stick with you until this is complete.
Please rate my service kindly.
Also it is the only way I am credited for my time and expertise with you.
Once you rate, I will be notified and will add your question to my priority list so you can reach me anytime until this problem is solved.
Then you can reach me by simply replying to this message anytime.
Thank you and have a great day!
