What can cause Fisher Paykel DD603 Heater Plate Fuses to Blow?

I've got a Fisher Paykel DD603 double drawer dishwasher, and the heater plate fuses keep blowing.

What can cause that?

Can that be caused by a bad controller board (the one at the front top right of the drawer face)?

Or, can that be a problem with the main board at the bottom in the back.

The problem would most likely be caused by a shorted or shorting heater element. You'd need to disconnect the wiring to it and using an ohmmeter set to a high scale..... check from each terminal to ground. You should not measure any continuity.

Both the upper and lower fuses keep blowing. I took out the main board in the bottom in the back, and this is what it looked like.

Does the corrosion on the screw mean anything. What are those fibrous particles sprinkled about?
