No Power to fill valve

Alll of a sudden, the dishwasher would not fill up with water.

I tested the old fill valve and found it to be operational when AC is applied.

I used the documentation to determine that there is NO power to the fill valve under any circumstances.

Ideas ??

PS: It occured to me that the onset of this problem was accompanied by the strong smell of something ‘burning up’ underneath the machine.

Thanks !!!
