A Complete Guide To GE Dishwasher Air Gap

Have you ever wondered whether there is a mechanism that prevents filthy and contaminated water from entering your GE dishwasher?

The answer is a resounding yes! Allow me to introduce you to the ingenious device known as the Air Gap.

Quick Info

A dishwasher air gap is a gadget near your sink that prevents filthy water from entering your dishwasher. It looks like a small pipe some inches above your countertop. This little thing plays a huge role in keeping your dishwasher safe from contaminated water that could ruin your dishes.

So, the air gap acts like a shield, ensuring the dirty water stays away from your dishwasher. In that manner, your dishes come out sparkling and shiny, just as you need them.

In this article, I’ll walk you through the process of the Air Gap, how to install it, and how the air gap prevents the backflow of the water. Let’s get started.

How Does GE Dishwasher Air Gap Work?

How Does GE Dishwasher Air Gap Work?

There are two hoses involved in the air gap. One hose is from the dishwasher, and the other goes to the drain. The air gap sits in the center, like a junction.

This way, the dishwasher hose reaches up and down through the air gap. At the top, the hose ends and lets the water out through the air gap. From there, it flows down the other hose to the drain.

The cool part is that these hoses are installed so they never meet. So, even if the drain gets clogged or messy, the grimy water can’t find its way back into your dishwasher.

Installing it is not rocket science, either. You connect one hose from the dishwasher to a part of the air gap, and the other hose goes to the drain. It’s all about ensuring these hoses are installed correctly to keep your dishwasher safe from the gross stuff.

How to Install GE Dishwasher Air Gap?

If you are looking to install the air gap for your GE Dishwasher, here’s how to do it:

  • You’ll need hoses, clamps, and the air gap itself. Also, get an electric-powered drill and a hole saw if your countertop doesn’t already have an air gap hole.
  • Find the air gap hole in your counter. If there’s none, mark where you want it and use the drill to make a 1-3/8” hole. But be careful, particularly with fancy countertops like granite or marble. You should get professional help for this.
  • Connect one hose from the dishwasher to a small part of the air gap. Use clamps to hold them tight. Then, hook the other hose to the drain or garbage disposal. Make sure it is snug.
  • Push the air gap through the hole on your counter. Tighten it with a wrench to keep it steady. A decorative cover goes on top to make it look neat.
  • Run your dishwasher to see if there are any leaks. Keep an eye on things to ensure water is not leaking out.

The process is quite straightforward. Ensure those hoses are connected snugly and the air gap sits tight within the hole you made or found.

Why Do You Need GE Air Gap to Prevent Backflow?

Why Do You Need GE Air Gap to Prevent Backflow

When your kitchen sink is all clogged up, the water tries to go back instead of forward. That’s backflow.

Here’s the problem: If there’s no guard like the air hole, that backflow will likely drag dirty water from the drain straight back into your dishwasher.

Cross-contamination is a big deal in plumbing. That’s when the clean water you use to clean dishes gets mixed up with the icky stuff from the drain. Imagine washing your plates in a pool of drain water – not cool, right?

So, preventing backflow isn’t just about keeping the dishwasher safe. It’s also about ensuring the water you use remains clean. 

That’s why having something like the air gap is a lifesaver, keeping the bad stuff out of places where it doesn’t belong.

Frequently Asked Questions

GE dishwasher water may come out of the air gap due to a clog or blockage in the drain hose or the air gap itself. Check for any debris or obstructions and clear them to restore proper water flow.

Not all dishwashers have an air gap. To determine if your dishwasher has one, look for a small cylindrical device located on the countertop or sink by the dishwasher. If it’s not there, your dishwasher likely uses an alternative method for preventing backflow.

Cleaning a dishwasher air gap is relatively simple. Start by removing the cap or cover of the air gap. Then, gently scrub away any dirt or buildup using a small brush or pipe cleaner. Rinse with warm water and reassemble the air gap to complete cleaning.


With the GE Dishwasher, or any other dishwasher for that matter, you need an Air Gap to get the most out of it. 

Clean water guarantees that your dishes are washed with clean water rather than contaminated water. 

You can install Air Gap with the step-by-step procedure or consult a professional to come and fix it if you feel like it.
