How to Clean Dishwasher Air Gap: Quick & Effective Tips
To clean a dishwasher air gap, remove the cap, extract any debris, flush with water, and scrub with a brush. Reassemble once clear and flowing freely.
Understanding the Dishwasher Air Gap
What is a Dishwasher Air Gap?
An air gap is a simple, yet crucial, component that helps keep your dishwasher running smoothly and your drinking water safe.
It is a small device that prevents contaminated water from flowing back into the dishwasher, which could otherwise lead to health issues. The air gap acts as a barrier to stop dirty water from returning to the dishwasher or entering your clean water supply.
Purpose of the Air Gap
The primary purpose of the dishwasher air gap is to protect your clean water. Without it, wastewater could potentially siphon back into the dishwasher or worse, into your fresh water lines, due to a sudden change in pressure.
This can happen if there is a clog or blockage in the system. The air gap ensures that there is a space of air that prevents this unwanted flow of water.
Finding the Air Gap in Your Kitchen
The air gap is typically located on the kitchen countertop near the sink or mounted on the sink itself.
It often looks like a small, metal or plastic cylinder, sometimes with a decorative cap, and usually has two hoses connected to it underneath the sink—one coming from the dishwasher and the other going to the garbage disposal or drain.
Identifying Your Dishwasher Air Gap
To confirm you have located the right device, look for a small fixture sticking up from the sink area with a cap that may be the same color as your faucet or sink.
This is the visible part of the air gap. You can often lift the cap to see the opening where air is allowed to enter.
Step-by-Step Cleaning Process
Tools and Materials Needed
Before you start cleaning, gather a few simple tools: a screwdriver, a bottle brush or pipe cleaner, and a bucket or bowl. You may also need some white vinegar or mild dish soap for more thorough cleaning.
Step 1: Remove the Air Gap Cover
First, take off the cap of the air gap. This is usually done by simply pulling it straight up or by gently twisting it off. Some models might require a screwdriver to loosen a screw that’s holding the cap in place.
Step 2: Inspect for Visible Clogs and Debris
Once the cover is removed, peep inside for any visible obstruction. Bits of food, grease, and soap scum can accumulate here.
Remove whatever debris you can see with your fingers or with the help of a tool, but be gentle to avoid pushing the clog deeper.
Step 3: Clean the Air Gap Vent
Next, clean around the vent area, removing any buildup on the edges. Wipe it down with a damp cloth or sponge. If there’s a lot of residue, you might want to use a bit of dish soap.
Step 4: Deeper Cleaning with a Brush
If the clog seems to be deeper, use a long bottle brush or pipe cleaner. Gently insert it into the air gap and move it up and down to dislodge any blockages. Be careful not to force it, as this could damage the pipes.
Step 5: Flush with Water or Vinegar
After brushing, it’s time to flush the air gap. Pour a mixture of white vinegar and water or just plain water through the air gap opening.
This can help flush out any remaining debris. If you’re using vinegar, let it sit for a few minutes to break down any buildup before flushing with water.
Step 6: Reassembling the Air Gap
Once everything is clear and clean, put the air gap back together. Replace the cap by pushing it back on or securing it with a screwdriver if necessary. Make sure it’s snug, but don’t over-tighten as this could cause damage.
Maintenance Tips for Dishwasher Air Gaps
Regular Checks for Functionality
Keep an eye on your dishwasher air gap and check it regularly for signs of clogging. A simple visual inspection every few weeks can help prevent bigger problems.
Listen for unusual noises or look for water coming out of the air gap, as these can be signs of a blockage.
Preventing Clogs
To prevent clogs, make sure you’re scraping dishes well before loading them into the dishwasher.
Avoid putting grease or oil down the drain, as these can solidify and block the air gap. Regularly clean your dishwasher’s filter, if it has one, to keep the system running smoothly.
When to Seek Professional Help
If you’ve tried cleaning the air gap and are still having problems, it might be time to call a professional.
Persistent clogs, water damage, or unfamiliar plumbing configurations are all good reasons to seek help. A professional plumber can ensure that your air gap and dishwasher are in good working order.
Signs That You Need Expert Assistance
Don’t hesitate to call a professional if you notice persistent bad smells, water backing up into the sink, or if the air gap is continuously spewing water. These can be signs of bigger issues that require expert attention.
