Prevents water from leaking from beneath the lever handle.
Replace if tightening the adjusting ring does not stop the leak.
Leaks worse than before Input in the new parts. Roger worked hard with me to get the job done but to no avail. This series of dishmaster - 2000 - is pathetically poorly function able. We had a tank type for at least 35 years and no problems. This very nice looking unit has had to be replaced totally to fix it the first time and we should've known better than to purchase the same thing again. Now the guts replaced and drips constantly. We are extremely unhappy with this unit as my wife has used one for at least 50 years and just wants one that turns off after use.
Per our phone conversation, the parts need to be installed correctly per the instructions.
Great help as always, easy to fix,: I have been a Dishmaster user for 45 years Great product.
