Failure to do so can result in leaks, water damage, and costly repairs. In this section, we will guide you through the process of connecting your dishwasher to the water and drainage systems.
Water Supply Lines
The water supply lines should be connected to the dishwasher’s inlet valves, which are usually located at the back or bottom of the appliance. It’s essential to use the correct type and size of tubing to prevent kinking and ensure proper water flow. The most common types of tubing used for dishwasher connections are 1/2-inch and 5/8-inch copper, PEX, or PVC tubing.

- Turn off the water supply to the dishwasher by locating the shut-off valves and turning them clockwise.
- Connect the tubing to the inlet valves on the dishwasher and tighten the fittings securely.
Drainage System
The drainage system should be connected to the dishwasher’s drain hose, which is usually located at the bottom of the appliance. The drain hose should be routed to the sink drain or a dedicated dishwasher drain, making sure it’s not kinked or blocked. The drain hose should also be secured to the dishwasher and the sink drain using clips or straps.
