The Blue wire, is the neutral leg of the motor and detergent cup of the bi metal, you were probably reading the voltage from the motor winding.
The Yellow/Black wire is the power to the bi metal from the timer.
With a multi meter, check for a resistance reading across the two terminals, with the wires off, on the bi metal switch, on RK1 scale on your meter. You should have a reading, if the switch is good.
Check the yellow / black wire from the detergent cup bi metal to the timer connection, for broken, loose, etc.
Leave the yellow/black wire off the bi metal switch, start the dishwasher at the main wash cycle, approximately 4or5 minutes into the wash cycle there should be 120 VAC on the yellow/black wire, If no voltage you'd have a bad timer or wire.
I'm sure you'll know what to do, and the part needed from there.
