A dishwasher schematic is a detailed, illustrated diagram of the dish-washing unit. A schematic is useful when trying to diagnose a problem or find a part.
Each major part is shown in the illustration. If the dishwasher is missing a part, the user can discover which part is missing by looking at the schematic. Users can also use the illustration to figure out if any part or parts are not working correctly. It may be something the user can fix on his own, or he may need to order a part or have a service technician come in to take a look.
