Hi Only Just,

Another great confidence booster!

Given that wonderful suggestion, I snapped some more pics, just now, of
under the sink where the dishwasher water seems to be coming from instead
of looking under the "kickplate" where the dangerous-looking wires are.

It looks like a wire and two hoses come out of the dishwasher:

The white hose seems to go to the garbage disposal

The steel hose seems to come from the (badly corroded) hot water input:

Something, I'm not sure why there are three hoses, goes into the sink:

Does something here look like what you are describing might be clogged?
