Whirlpool WP3347034 Washing Machine Vacuum Break

The Whirlpool WP3347034 is an important but little component in your Whirlpool washing machine. During the drain cycle, a vacuum break of a one-way valve keeps tainted drain water from recirculating back into your washing machine. The vacuum break, which is part of the drain hose system, lets air into the hose when it's necessary to keep a vacuum from developing. This guarantees appropriate drainage and keeps possibly dangerous effluent out of your machine again. Poor vacuum breaks can cause clothing to drain slowly, smell bad, or even get contaminated. To maintain optimal drainage efficiency and safeguard your washing machine from potential contamination, replace a worn-out or faulty vacuum break with a genuine Whirlpool WP3347034.
