Amica PBF4VI506FT - induction hob F5 or blinking digits of heating level.

Colleagues (and friends),

what can be with the induction plate as in the topic that sometimes displays F5 or does not switch on the heating - individual displays blink (from the "burner" being started).

For example - I start heating on one "burner" (and it works OK), then I try to start heating in the second field and then the second field starts to blink the display and unfortunately it does not heat up. It happens to attach 2 fields correctly, but running all together borders on a miracle.

F5 sometimes turns on when switching on the board, sometimes during operation on the panel - as if it were a typical error indicating the driver board failure, but is it really only this?

I will be grateful for any constructive attention.

I replaced the "software panel" board and everything works almost perfectly.

There is only one almost - after turning on the power supply to the induction hob F5 is displayed for a few seconds - during this time nothing can be done with the disc. After this time, the disc switches off (automatically) and you can now use it normally. I do not think that this initial ritual is normal.
In addition, it was noticed that when I boil (for example) a large amount of water, after boiling and turning off the cooking zone, the fan is started (apparently normal) and F5 then jumps in for a moment (I have no information if F5 jumps on or off).

Maybe this additional information would encourage some specialist from the above equipment to share knowledge.

it's probably a production defect of amica induction plates. From now on I am also struggling with error f5, if someone has a way to do it, I am asking for a hint

For me after the exchange of the "software panel" the induction works, but more and more often it appears F5. It did not last even a year.
The only way to do this is ... unless you replace the oven with a new one.

I was having one phase, it was a shame to admit the fuse was fired. One click and induction works as needed
