It is a white Kitchenaid Superba model KDS-17A with the "Energy Saver" option button. The Singer timer is dated MAR 1 76. The original fill valve assembly seems to have been replaced with a KDC-17 fill valve assembly. Other than this dishwasher not filling with water, it is in pretty good condition other than some flaking of the door panel under-edge.
Up until a couple of weeks ago, it worked fine for over three years. Then one day it just stopped filling. I have removed and cleaned the water valve and shut-off valve but it still will not fill. Send me an email at ces3rd@gmail.com and, if I still have it, it's yours free. I'll even help load it.
