Ken,that is the same G.E. dishwasher I did my first Bob load in when I was age 6. Packed it really full. I wanted to get them really CLEAN so I put every thing I could find under the sink in it,extra too and turned it on. Those into suds would have been proud! Suds were spitting out the front grill and flowing down he galley kitchen floor. Talk about a tub full of suds! The dial on ours was different. It was white with black letters,no colors.
