Dishwasher - High Loop Missing

Report Description:

There is no visible high loop observed at the dishwasher drain line.

The high loop helps to prevent drainage from the sink and into the dishwasher or the creation of a vacuum from the waste lines. It is best to refer to the dishwasher manufactures specifications. Further evaluation and repair or replacement as needed by a qualified specialist is recommended.

What does it mean?

A high loop is a section of the drain line that is raised higher than the water level in the sink. It helps prevent the backflow of water from the sink into the dishwasher. An air gap is also acceptable. This is a physical separation between the dishwasher drain line and the sink drain line, typically achieved by a small device mounted above the sink. It prevents contaminated water from flowing back into the dishwasher and avoids the creation of a vacuum which can impede drainage. Each dishwasher model may have specific installation requirements and recommendations provided by the manufacturer.

What is the most common solution?

It's important to refer to the dishwasher's installation manual or contact the manufacturer directly to determine the specific requirements for installing either a high loop or an air gap. In many cases, installation of a high loop or air gap may require plumbing expertise. It's advisable to hire a professional plumber or technician to ensure that the installation is done correctly and complies with relevant regulations. By installing a high loop or air gap according to the manufacturer's specifications and current standards, the drainage system of the dishwasher can be properly configured to prevent issues such as backflow and vacuum creation, ensuring efficient and safe operation.
