Same old! Same old!
Whitekingd,
The dispensers were the same on the 14 thru the 18's so if you find one in good shape, have at it. You may have to replace the gaskets but you can still get them from Hobart if Whirlpool doesn't carry them any more. If you need a part number, let me know and I will give you the current one so you can order them.
Hope this helps.
Steve
