Very disappointed. About a year ago, we purchased a new Dishmaster, which started leaking and apparently needed new washers. Unlike our Dishmaster of 40 or 50 years ago, which had valves manufactured to permit the easy replacement of the washers for a few cent (washers were held by small screws), there has been a re-design - apparently to prevent replacement of the washers (which now are permanently attached by a non-removable plastic pins) and rip off the consumers by requiring the complete replacement of the entire valve assembly (now made of cheap plastic instead of brass) for more than $40 (for the pair of hot and cold). For shame.
Not so! The valve stem ends are easily, and affordably, replaceable:
If you choose to replace only the washer, it is available at your local hardware store: 1/4 R (9/16 OD) bibb washer, flat, non-beveled
The valve stems are made of brass, not plastic. And, it is unlikely that any parts needed to be replaced at all. The handles simply needed a quick adjustment as covered in the installation instructions and the maintenance section of the manual. See this video:
