When selecting a dishwasher, look for:

• Energy efficiency
• An option for heat-drying and air-drying
• AAmpere (amp), SI unit of electrical current feature that senses how dirty the dishes are and runs appropriate cleaning cycles
• A multiple-level wash system
• A thermostat and heating capability

Most dishwashers clean dishes as well as the next; however, higher priced ones are generally quieter. Most models fit into a 24-inch-wide space under a kitchen counter top and are attached to a hot-water pipe, drain, and an electrical line. They can have a gravity drain or be fitted with a drain pump.

The dishwasher should be ACAlternating current and therefore has an impact on requirements for a DCDirect current-AC inverter. Dishwashers are energy rated in kWh/yKiloWatt-hours per year, typically 700-850. They draw around 9 A or more when running, depending on the features. (See ElectricalCapacityAC).

Check the water pressure requirements, typically 100-145 psiPounds per square inch, and make sure you have enough pressure in the galley.
