Ian J. for Model Number a107 What is the purpose of the plastic connection on the injector hose? What is the principle of operation?
Answer Hello Ian, The "plastic cup" and injector valve WP206680 was put in to satisfy environmental laws concerning water having the ability to siphon back into the fresh water supply. In other words, it was designed to be a one way check valve from the water supply to prevent back flow. Unfortunately, without completely eliminating the part, if the injector 12001677 is malformed, water will spray to the side instead of straight into the inlet tube if the rubber sleeve, causing a leak. So if the injector valve sleeve is malformed, it requires replacement. Read More... Answered by AppliancePartsPros.com | Friday, March 17, 2017
