Sears Parts Direct is one site that offers PDF versions of Roper washer repair manuals. Another website that has a number of Roper washer manuals is Manuals Online.
Both Sears Parts Direct and Manuals Online have a huge collection of PDF versions of repair and instruction manuals for washers, driers and other appliances. Both sites have downloadable links that are arranged by the model number of the washer. Sears Parts Direct has a mechanism that allows people to buy parts they might need in order to fix the washer, while Manuals Online simply lists the manual needed for a washer.
