I am looking to find a Kitchenaid KDS-18 dishwasher to replace my Whirlpool from the 1990s. If anyone sees one for sale please let me know. Color is not important.
Keep your eyes open on CL, don't discount a KDS-20 if you find one as well, they are just like the 18 just w/o constant rinse, which would likely already be broken off on an 18 by now anyway.
I wouldn't get hung up on a Superba 18, the Imperial, Patrician, and Custom 18 Series models all were excellent performers, imo, I've had several of them.
