Installing a dishwasher involves several key steps, including connecting electrical and water lines, positioning the unit, and securing it properly.
Here's a breakdown of the typical installation process:
Preparing for Installation
Before you begin, ensure you have the necessary tools and that the installation area (usually under a counter) is prepared with access to electrical, water supply, and drain connections. Always turn off the power and water supply to the installation area before starting work.
Installation Steps
Based on common installation procedures, here are the key steps involved:
1. Identify the Access Panel
Most dishwashers have an access panel at the bottom, often secured by screws. Removing this panel allows you to access the connection points for the electrical cord, water supply line, and drain hose.
2. Attach the Electric Cord
If your dishwasher did not come with a cord pre-attached, you will need to connect a new appliance cord. This involves feeding the cord through a strain relief connector and wiring it to the appropriate terminals inside the junction box, typically found behind the access panel. Ensure connections are secure and follow the manufacturer's wiring diagram.
3. Connect the Water Supply
Locate the water supply connection point on the dishwasher. This is usually a fitting near the front or side, often accessible once the access panel is removed. You'll need to prepare to connect the water supply line here.
4. Attach Water Supply Line
Connect a flexible water supply line, typically made of braided stainless steel or copper, to the water inlet fitting on the dishwasher. Use pipe thread sealant or Teflon tape on the threads to ensure a watertight seal. Hand-tighten first, then a quarter to half turn with a wrench.
5. Position the Dishwasher
Carefully slide the dishwasher into its designated space under the counter. Ensure it is centered and roughly aligned with the front of the cabinets. Be cautious not to kink or damage any of the connected hoses or wires as you slide the unit into place.
6. Anchor the Dishwasher
Once the dishwasher is in position, it needs to be anchored to prevent it from tipping over when the door is open. This is typically done by securing mounting brackets (usually found on the top or sides of the dishwasher frame) to the underside of the counter or to the side cabinets using screws.
7. Connect the Water Supply Tube
Connect the other end of the flexible water supply line to the hot water supply valve, usually located under the sink. Again, use thread sealant and tighten the connection securely but without overtightening.
8. Connect the Drain Hose
The dishwasher's drain hose needs to be connected to the drain system. This is commonly done via a connection on the garbage disposal or a dedicated drain standpipe under the sink. Ensure the drain hose is properly looped above the connection point (using a high loop bracket or routing it high under the counter) to prevent dirty water from back-flowing into the dishwasher (this is called an air gap or high loop). Secure the hose connection with a clamp.
After these steps, you can typically restore power and water, run a test cycle to check for leaks, and then reinstall the access panel.
