What is the purpose of a dishwasher drain connector and how does it function in the overall drainage system of a dishwasher?

The purpose of a dishwasher drain connector is to connect the dishwasher's drainage hose to the Plumbing system of the house. It functions by allowing the dirty water from the dishwasher to flow out through the drainage hose and into the plumbing system, preventing water from backing up and ensuring proper drainage of the dishwasher.
