Dishwasher heating coil replacement

Dishwasher Repair
1

The heating coil on my whirlpool dishwasher has broken in two and needs to be replaced. I ordered and received a replacement coil but I can’t see how to get the broken one out and how the new one should go in. there doesn’t seem to be a nut to loosen, just some sort of rubber washer with a somewhat corroded metal piece on top of it. Any suggestions?

Thanks.

The nuts (#3 on the break down diagram) are under the dishwasher and you have to remove the dishwasher from the cabinet to access them.
