Whirlpool Washer Washing Machine Siphon Break Assembly 285320

Factory Certified washing-machine siphon-break assembly for rubber and plastic drain-hose applications. The kit creates an air gap in the drain line to help prevent dirty water from siphoning back into the washer tub.

Is This the Right Part?

Common Symptoms

• Washer may fail to fill or may take too long to fill when drain siphoning occurs.
• Water may drain from the washer during the fill cycle.
• A siphoning or loud sucking sound may occur during draining.

Check Before Replacing

• Inspect the drain installation for an improperly positioned or missing siphon break, especially when the washer uses a floor-drain arrangement.
• Observe whether water drains from the tub during the fill cycle.
• Confirm that the installed drain hose and siphon-break assembly are appropriate for the washer's drain-hose configuration.
