Whirpool SMP 778C/NE/IXL. F12 error, induction plate

my whirlpool SMP 778C/NE/IXL induction hob no longer works and shows error f12 on two hobs. i tried the manual resolution several times (disconnect power for several minutes) but it doesn't work.

i want to replace the induction elements under the glass, how do i remove them?

You can buy them on the official Whirlpool website.

any other advice?

thank you very much.
