All dishwashers in the US are hooked up to a hot water supply line only. Cold water does nothing for cleaning dishes.
You can, but it would render the dishwasher useless for cleaning.
Hot water line. If you did hook it up to your cold water line make sure your dishwasher is set to heat the water (some models have a selectable setting for this.)

Cascade says it can be used in cold water.
Always use cpvc for hot water and PVC for cold water.
No, not all dishwashers are cold fill machines. Many older model dishwashers have a hot fill design. Only newer models are considered to be more advanced and have a cold fill design for energy efficiency.
the difference are as follows. the direct water supply comes from the outside main water supply directly into the sink. the indirect water supply has mains cold water collected in a cistern which in turn supplies water to the sink.
Someone hooked up the hot water supply to the toilet instead of the cold water supply- or your water heater is back drawing hot water through to the toilet from a cold water inlet (supply)
The cold water supply enters the tank at the bottom near the burner. Heat rises, as does hot water. The hot water supply is piped out from the top.

Usually the dishwasher is located near a sink. If you run the hot water at the sink, that will flush the cold water from the hot water line, so the dishwasher will end up getting more hot water during its fill, and allowing the water to reach higher temperatures. Use the "Heated Wash" option to ensure maximum temperature increase. Dishwasher detergent works best around 145 degrees, so the hotter the water going in, the better it will clean.
