Re: BX Wire Grounding for Dishwasher
Armour cable ( Type AC ) will have an armor of flexible metal tape and shall have an internal bonding strip of copper or aluminum in intimate contact with the armour for its entire length.

The armour of Type AC cable with an internal bonding strip is recognized as an equipment grounding conductor. Older armour cable that does not have the bonding strip can not use the armour as the equipment grounding conductor.
*** Side note ---
BX is a brand name --- orginally registered by GE -- and is commonly used to identify armour cable.
Much like Romex --- which is a brand name -- is used to identify NM cable.
Hopefully this helps.
