When it comes to maintaining our kitchen appliances, there are certain tasks that often get overlooked. One such task is checking and cleaning the dishwasher air gap. As a result, many homeowners are left wondering: what happens if the dishwasher air gap is clogged? In this article, we’ll delve into the importance of the air gap, the consequences of a clogged air gap, and how to prevent and fix this common issue.
What is a Dishwasher Air Gap?
Before we dive into the consequences of a clogged air gap, let’s take a step back and understand what it is and why it’s essential for your dishwasher’s proper functioning. The air gap is a vertical pipe that connects the dishwasher’s drain hose to the garbage disposal or sink drain. Its primary purpose is to prevent sewage and contaminated water from flowing back into the dishwasher, ensuring that your dishes are washed in clean water.
The air gap works by creating a barrier between the dishwasher and the drain system, allowing air to enter the drain hose and preventing siphoning. This is crucial because dishwasher drain hoses are designed to gravity-flow into the drain system, and without an air gap, sewer gases and dirty water can flow back into the dishwasher.
