Applies to Renters  
check Wash only full loads - it costs exactly the same to wash one dish as a whole load.
check Don't use the drying cycle - to save energy, use the "no-heat" selector or turn off the dishwasher after the final rinse. For even quicker drying, open the door slightly after you've turned the dishwasher off.
check Air dry dishes - if the dishwasher has an air-dry feature, use it.
check Fill the dishwasher according to manufacturer's instructions. This will allow the flow of water to properly clean the dishes.
check If you wash by hand - Rinse dishes in groups rather than one at a time & don’t leave the water running.
