Cool Dry: Not an error

From Service Manual 585834, p.46:

1.No action needed; user may open and unload the dishwasher or wait for automatic power off.

2.Measure line voltage at the power cord terminal block. Expected: 120 VAC (L1 to neutral) or 208 to 240 VAC between L1 and L2 under load.

3.Inspect the cord strain relief and terminal block screws for signs of arcing or heat discoloration. Loose connections here mimic an intermittent power failure to the control board.
