A tabletop dishwasher uses a drain hose, or an intake valve, that connects to a water source and an external plug for a power supply. The dishwasher's pump system is powered by an electric motor that switches between filling and draining the unit. The motor also powers pressurized spray nozzles that remove food and debris from dishes. According to HowStuffWorks, a dishwater motor runs in one direction and uses a solenoid to reverse the pump action and to power sprayer arms through the wash and rinse cycle.
