I've searched the model number but didn't find any information About this particular model. I'm being offered it for free from a house my cousin purchased.
You will want to have it someplace you can use it for when you get something really dirty that needs the power of the WP pots and pans cycle to really blast the dirt away. They used to call it Power Scour and it is. It will also scrub harder than the KA machines you have.
Can see from the pics it was used in hard water. If it were me, id be replacing the water inlet valve to assure no wash or flooding problems on a 30 year old machine.
