Can you post the product number again please as its been crossed out.
You need to prefix it with an A otherwise all I see is XXXXXXXXX.
Product number is XXXXX
Ok got it now thanks.
So when you turn the hob on the large front ring comes on on its own without you even turning it on?
Ok it wont be the element and it wont be the interface board as well.
What this will be is the main control board.
As on there are the relays and you will find one of the relays will be faulty causing this fault.
To access the board you need to remove the hob and then undo all the screws around the outside holding the glass top on and then you can remove it.
There you will see the interface board at the front. Lift this up and you will see the main control board under there.
You will need to replace this board and that will cure the fault here.
If you want the part number its(NNN) NNN-NNNN/p>
If you need anymore info just get back to me.
Worth every penny. Many thanks.
Your very welcome.
If you could rate the service I gave that would be great.
