How to Clean or Replace a Dishwasher Air Gap · Step 1 of 8
In this video
The first step is to disconnect the plumbing from the old garbage disposal. Use a screwdriver to loosen the hose clamp securing the dishwasher discharge line to the disposal inlet. Twist and pull the hose to detach it. Next, use the screwdriver to loosen the two screws holding the main discharge pipe flange to the side of the disposal. Once the screws are removed, the flange and the drain pipe can be pulled away from the unit. Be prepared for some water to spill out.
Goal: Disconnect plumbing from garbage disposal
- If the dishwasher hose is stuck, you can gently pry it with a flathead screwdriver, but be careful not to tear the hose.
- Have a bucket or a pan ready underneath the pipes to catch any water that drains out when you disconnect them.

FAQs
Why is my dishwasher air gap sputtering water onto the counter?
This is the most common symptom of a clogged air gap. Debris like food particles or grease from your dishwasher accumulates inside, preventing proper drainage and forcing water out. Cleaning the air gap thoroughly, especially the internal components and hoses, should resolve the issue.
What are the essential tools I'll need for this project, especially if I'm just cleaning the air gap?
For cleaning, you'll primarily need a pair of tongue-and-groove pliers to loosen the nuts, a screwdriver for hose clamps, and a flashlight for inspection. Don't forget old towels or a bucket to catch water. If replacing, these same tools will be used, along with the new air gap unit.
How long will this project realistically take a beginner, and what's the estimated cost?
For a beginner, cleaning the air gap typically takes 30-60 minutes, while a replacement might take 1-2 hours. The estimated 3 hours allows ample time for troubleshooting and cleanup. The cost for cleaning is zero, and a new air gap usually ranges from $30-$50, making it a very affordable fix.
Are there any crucial safety precautions or warnings I should be aware of before starting this project?
Always place a bucket and plenty of old towels under the sink to catch any spilled water, as disconnecting hoses will inevitably cause some leakage. Wearing heavy-duty latex gloves will protect your hands from grime and potential sharp edges. If you're disconnecting any electrical components related to the dishwasher, turn off the power at the circuit breaker first.
