The needle valve repair kit is the number one needed maintenance item. If you have one long enough you'll certainly need this, since the brass clip will eventually corrode and break. Fortunately it's easy to replace, it's inexpensive and over the years I've learned to have one spare. It would be far better if it were stainless steel instead of brass. I must say though customer service and reordering parts couldn't be easier, and obviously we love dishmaster products since 1965.
