Dishwasher
	Description A dishwasher is a mechanical device for cleaning dishes and utensils. Unlike manual dishwashing, which relies largely on physical scrubbing to remove soiling , the mechanical dishwasher cleans by spraying hot water on the dishes.

Maintenance Checklist

• Use dishwasher cleaner and deodorizer if the dishwasher is unused for a week or more because a bad odor may radiate.
• Clean the exterior of the dishwasher using a damp sponge and detergent.
• Regularly clean the filter, which is fitted near the bottom of the dishwasher.
• If rust forms on the dishwasher, eliminate using a rust remover.
• Over time, small holes in the spray arms of the dishwasher may become clogged. Use bits of paper or toothpicks to unclogged.
• Run the kitchen sink hot water for a few minutes before using the dishwasher to make certain the dishwasher has hot water.
