Timer problem/ soap dispenser

Had service tech replace my timer. Dishwasher worked fine just would not advance thru cycles. After he replaced timer sopa dispenser door will not latch & no water( no power to valve) to dishwasher. Service tech returned & told me the wiring diagrham is missing & I would have to pay to order one. I would like to repair myself if anyone can help me with technical info. Seems like he miss wired the timer? Soap dispenser not hooked up correctly? Thanks.
