Cooker laureat2, grill repaired cos chopping board melted on it?

Would it be possible to get the grill repaired or partly replaced on my laureat2 cooker? Somebody managed to put a plastic chopping board on top of the grill and it melted through the grill. I got most of it off but some still remains embedded in it and possibly toxic (Plastic). The rest of the cooker still works well and seems a shame to just get rid of it but I really need a grill again. So just wondered if anyone had any ideas as to repair or not? Thanks.
