Can you post the model number please.
Is this a 4 burner hob?
Model number. :AKL359/NE/02Yes it is a four burner.
Ok this has to be hard wired to a 32 amp cooker switch im afraid. A 13 amp plug top will just burn out and it can cause a fire.
So get the hob hard wired to a 32 amp supply and this should sort it out for you. Let me know how it goes.
