Do Dishwashers Need to Be Plumbed In? 

Short answer: 

Most built-in dishwashers must be permanently plumbed to a hot water supply and drain line. However, portable models only require a temporary faucet connection. 

Detailed answer: 

Built-in units need permanent connections. They connect directly to your hot water line and drain into the sink or garbage disposal. The hose must be routed properly to prevent dirty water backup.

Portable dishwashers are different. They skip permanent pipes, temporarily connecting to your kitchen faucet and draining right into the sink.

If your kitchen lacks proper shutoff valves or drain connections, you will need a qualified plumber.
