Abstract
A domestic clothes washer incorporating a system for dispensing predetermined amounts
of liquid treating agents wherein an add-on storage tank reservoir is mounted on the washer control console.
User operated valves provide gravity flow of the agents from the reservoir into dispensing vessels on the
console. The vessels include calibrated viewing windows allowing the user to manually fill the vessels with
wash agents to selected levels prior to each washing load for subsequent automatic emptying and passage into
the washer during predetermined operations. Means are also provided to flush at least one of the emptied
dispensing vessels to the washer drain by diverting a portion of the washer rinse water therethrough.
