My new Thermadore dishwasher 651gfp does not dry, my contractor said he did not put an air gap, the manual said not necessay. Is it the reason why it does not dry the dishes? I lost the user guide that came with it delivered from Pacific Sales. Can you send me another one free? Melinda Louie P. O. Box 3137,South pasadena, CA 91031 Cell (626)823-8724 Thank you very much.
