Bissell Proheat 2 Model 9200-2?

I bought this for my mother and she used it like maybe 6 or 7 times .Then she used cascade in it instead of a liquid detergent she used powdered and it never worked again . Instead of taking it to a repair shop . She { a 71 yr old woman} Decided to take it apart and clean the tubes . It is completely disassembled . This thing cost me like 300 bucks. I need the bissell repair manual to put it back together .I hope someone can tell me where to find it. It is a newer one 9200-2 bissell proheat 2 with 2 x the brushes.
