Hi, Ione. A couple of years ago Buck and I purchased a Jenn-Air dishwasher at a local thrift store. Needless to say there was no instruction manual. We contacted Jenn-Air
and after giving them the model number and serial number, they were able to give us the age, manufacturing information and instructions for it. You might do the same thing after clicking on the link I've posted. Good luck.
We were very pleased with the response we received from the folks at Jenn-Air.
