According to Wikipedia a dishwasher is a machine used to clean dishware, cookware and cutlery automatically. Unlike manual dishwashing, which relies heavily on physical scrubbing to remove soiling, the mechanical dishwasher cleans by spraying hot water, typically between 45 and 75 °C (110 and 170 °F), at the dishes, with lower temperatures used for delicate items.
When a dishwasher is acting up usually there is an issue that requires repair or service.
