In the 2011 NEC 422.31 has been re-written to include Appliances Rated over 300 VA and Motor Operated Appliances Rated Over 1/8 HP. This eliminated the confusion generated by 422.32 which has been removed from the code text.
My question is regarding dishwashers, do they generally have motors rated at 1/8 HP or greater? If so then I'm asuming that breaker lock outs are out as the exception to a disconnecting means within sight.

in place with or without the lock installed.

see 422.34.
(C) Motor-Operated Appliances Rated over 1⁄8 Horsepower.

Exception: If an appliance of more than 1⁄8 hp is provided
with a unit switch that complies with 422.34(A), (B), (C), or
