I dont know if those instructions work every time.
My dishwasher sort of cause into a confused seizure when you interrupt it. It doesn't really resume, it seems to flush its water tank and start over with a fresh batch.
You and me, buddy, will be cleaning our dishwashers this week. May I suggest you take OUT the arms, lay them in a shallow bucket large enough to hold the arms, then soak in CLR to let it sit for 24h or something.
