How to Clean or Replace a Dishwasher Air Gap · Step 1 of 8
In this video
Before beginning, ensure the garbage disposal is unplugged from the power outlet to prevent electric shock. If a dishwasher is connected, use a 3/8' nut driver to loosen the hose clamp and detach the dishwasher's drain hose from the disposal's inlet port. Be prepared for some water to drain out. Next, use the 3/8' nut driver or a flat-head screwdriver to unthread the two screws securing the tailpipe flange to the main drain outlet on the disposal.
Goal: Prepare for removal
- Failure to unplug the unit can result in serious injury from electric shock.
- Have a bucket or towel ready to catch any water that may spill from the hoses.

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.
