Did You Know?
1. The air gap on a dishwasher is a small plastic or chrome cylinder, usually located on the countertop or on the sink next to the faucet. It is there to prevent water backflow in case of a clog in the dishwasher drain hose.
2. The concept of the dishwasher air gap was first introduced in the late 19th century as a solution to prevent contaminated water from re-entering the clean water supply.
3. In some regions, local plumbing codes require dishwashers to have an air gap installed, while in others it is optional. It is always a good idea to consult your local building codes to see if an air gap is mandatory in your area.
4. The air gap works by creating a physical separation between the dishwasher’s drain hose and the sink’s drainpipe or garbage disposal, preventing any potential backflow from contaminating the dishwasher or the clean dishes.
5. Dishwashers with built-in garbage disposals often require an air gap because the disposal can generate enough pressure to cause water to flow back into the dishwasher, resulting in unsanitary conditions.
Location And Function Of The Air Gap On A Dishwasher
The air gap on a dishwasher is a crucial component of its plumbing system. It is a chrome plated cylinder that is typically located on the back of the sink, near the faucet. Its primary function is to prevent contaminated water from flowing back into the dishwasher.
When the dishwasher is in use, wastewater from the cleaning process is drained out through a pipe connected to the bottom of the machine. This water then flows into the air gap, where it is directed into a separate drainage system. The air gap creates a physical space between the dishwasher and the sink drain or garbage disposal, ensuring that any clogs or blockages in the drain do not contaminate the dishwasher with dirty water.
Plumbing Codes And The Presence Of Air Gaps
It is important to note that not all areas have plumbing codes that require the installation of an air gap on dishwashers. Consequently, some dishwashers may not feature an air gap. However, even if it is not mandated by local regulations, having an air gap is highly recommended to prevent potential contamination of the dishwasher.
Plumbing codes are established to ensure the health and safety of users in a given area. The presence of an air gap helps to comply with these codes, as it acts as a reliable safeguard against backflow. The risk of contaminated water entering the dishwasher is significantly reduced when an air gap is properly installed and maintained.
Cleaning And Maintenance Of The Dishwasher’s Air Gap
To ensure the proper functioning of the air gap, it is essential to keep it clean and free from blockages. Over time, debris and sediments can accumulate within the air gap, potentially obstructing the flow of water and compromising its effectiveness.
To clean the air gap, the first step is to locate the chrome cover on the back of the sink. This cover needs to be carefully removed. Once the cover is off, you will see a plastic cap. Unscrew the plastic cap and remove any accumulated material carefully. It is advisable to rinse both the plastic cap and the air gap thoroughly under running water to ensure they are completely clean.
Regular cleaning and maintenance of the air gap are crucial to prevent any issues with drainage and potential contamination of the dishwasher. It is recommended to clean the air gap at least once every few months to maintain its optimal performance.
Checking The Hose For Clogs In The Air Gap System
In addition to cleaning the air gap itself, it is essential to regularly check the hose connected to the air gap. This hose is responsible for carrying the discharged water from the dishwasher to the sink drain or garbage disposal. Over time, this hose can become clogged or blocked, hindering the water flow and potentially causing issues with the dishwasher.
To check the hose for any clogs, simply detach it carefully from the air gap and visually inspect it for any obstructions. If any debris or blockages are detected, they should be removed promptly to restore proper functioning.
Checking the hose regularly is a recommended part of dishwasher maintenance to ensure the entire system is functioning correctly and to prevent potential issues.
Bullet points:
- Clean the air gap regularly
- Check the hose for clogs or blockages
- Detach the hose from the air gap to inspect it visually
- Remove any detected debris or blockages promptly

Frequently Asked Questions
Do all dishwashers have an air gap?
No, not all dishwashers come equipped with an air gap. In fact, it is surprising to learn that many dishwashers do not have built-in backflow prevention or an air gap. However, some dishwashers have a clever alternative solution to prevent backflow, where the drain hose is looped upward and attached to the bottom of the countertop. To ensure compatibility and proper installation, it is always advisable to consult the owner’s manual before ordering and installing a dishwasher.
What if dishwasher has no air gap?
If a dishwasher does not have an air gap, an alternative solution could be implementing a high loop in the drain hose to prevent any potential backflow of drain water. This method, although not in accordance with code compliance, serves the same purpose as an air gap by ensuring that the dishwasher remains protected from contaminants. However, it is important to note that adhering to local plumbing regulations and installing an air gap is the recommended approach to ensure optimal functionality and safety of the dishwasher.
What is the air gap on a dishwasher?
The air gap on a dishwasher is an essential component that ensures the proper functioning and cleanliness of the dishwasher. Positioned between the kitchen sink drain and the dishwasher, this cylindrical fitting prevents the flow of dirty water into the dishwasher while also preventing the reverse flow of water during a wash cycle. By creating a gap between the sink and the dishwasher, it acts as a reliable barrier, effectively safeguarding the dishwasher from potential water contamination.
Does Bosch dishwasher need air gap?
Yes, it is highly recommended to use an air gap with a Bosch dishwasher. According to the Bosch Instruction manual, if an air gap is not used, the drain line should be elevated above the highest water level of the sink to avoid back siphoning into the dishwasher. However, an air gap provides an extra layer of protection by creating a physical gap between the dishwasher and the drain line, preventing any potential contamination or backflow from the sink. Therefore, installing an air gap ensures the optimal functioning and safety of your Bosch dishwasher.
