Hi and thank you for using Just Answer.
Per your problem, your code shows a fault in the circuit boards. Basically, they got over heated. This is a common problem for these types of units. Not knowing how old this hob is, the only reasons you would get a code like this would be improper ventilation for the heat to dissipate or the circuit boards has reached its end of life. Even with good ventilation these boards do get very warm and after a period of time of heating and cooling it takes the toll on them. You can this ... turn the power off wait for two minutes and then turn it back on. This will clear out the memory. If the code comes back on, you need to replace the boards. Now, if this hob resets it's self and you get no code, however after usage and the code comes back then us have a ventilation problem. If you have any other questions, please ask. I wish you the best.
