How to Install a Dishwasher Air Gap on a Countertop · Step 1 of 6
In this video
With the drain hose and disposal confirmed to be clear, the issue is likely with the pump. To access it, you must remove the dishwasher. First, ensure the power is off at the circuit breaker and the water supply is turned off. Open the dishwasher door and locate the two mounting brackets at the top, securing it to the countertop. Unscrew these brackets. Then, remove the bottom kick plate cover by unscrewing the two screws holding it in place. Carefully slide the dishwasher forward and out of the cabinet.
Goal: Remove the dishwasher from its cabinet to access the pump
- Double-check that the power is off at the breaker before proceeding.
- Lift the front of the dishwasher slightly as you pull it out to prevent the feet from scratching the floor.

FAQs
Why is an air gap necessary, and is it always required for a dishwasher?
An air gap prevents contaminated drain water from siphoning back into your clean dishwasher, protecting your dishes and health. While not universally required, many local plumbing codes mandate them, so always check your local regulations before installation.
What are the main safety precautions I should take when drilling the hole in my countertop?
Always wear eye protection and gloves. Securely brace the countertop from below if possible, and use the correct hole cutter (like the Malco HC1S) at a slow speed to prevent chipping or cracking. Start with a pilot hole for accuracy and control.
My new air gap is leaking after installation. What should I check first?
The most common leaks occur due to loose hose clamps (ensure they are tightened properly, like the Everbilt 5/16 - 5/8 in. clamps), improperly seated hoses, or damaged gaskets on the air gap body. Double-check all connections and the integrity of any rubber seals.
Is the 4-hour estimated time realistic for a beginner, and what makes it take that long?
Yes, 4 hours is realistic for a beginner. This accounts for thorough preparation, careful drilling (especially for a first-timer), routing hoses, making secure connections, and meticulous testing for leaks, which can take time to get right.
