Dishwasher really need dedicated circuit?
If a dishwasher only takes 8 Amps, does it really need a dedicated circuit from the circuit breaker box?

Someone will correct me if I am wrong, but I believe it is code to have the DW on it's own breaker (because it's hardwired?), built in microwave and I *think*, the washing machine outlet.
I know in my (200 amp) panel, these items have their own breaker:
water heater
dryer outlet
microwave outlet
dishwasher
washing machine outlet
whirlpool pump
whirlpool heater
heat pump sub panel

The electrical code does not require the dishwasher to be on a dedicated circuit. But it does require you to follow manufacturer's instructions.

bear in mind that you can only load a circuit to 80% of the maximum wire rating or breaker size, therefore you may share the circuit but be careful you are sharing with a lighter load and something that will not surpass 12 amps if on a 15 amp breaker or 16 amps on a 20 amp.......and so on

The 80 percent rating for circuits only applies for certain type of circuits. It does not apply to the circuit the dishwasher is on.
However, you cannot simply put the dishwasher on any circuit you chose. For example, it cannot be on the same circuit as a kitchen counter receptacle.
Many people put the dishwasher and the garbage disposal on the same circuit, because these two appliances are usually in the same area of the kitchen, and because they can control when they run them.

Although there are many specific codes requiring the use of no more than 80% of a circuit capacity, there is no such blanket rule. And there is no such rule that applies to a dishwasher. For example, unless otherwise prohibited by the manufacturer, code allows you to put both a dishwasher and a disposal on the same circuit, and those two appliances may indeed use 100% of the circuit capacity when both are on.
