Info: Whirlpool wtw8900bc0 Modified Energy Factor, 2.5

I was helping someone fill out a rebate for a new washer and got stuck on the part to fill in the Modified Energy Factor (2.5 for this washer). This turned out to be more of a hassle than I thought. I even went through the manual (although I did just skim through it because it was primarily an instruction manual). Searching did not turn up the model number. After truncating the model number, I did find one site with the information.
