My washer was reading the nf error code during the rinse cycle.We have replaced the water valve dispenser.I ran a load and the nf code did not come on but the water still seems to fill really slow during the initial rinse filling and the washer still makes a humming sound.I put some fabric softener with some water in the dispenser and the fabric softener did not go into the washer.The second rinse seemed to fill normally.I know that the water to dispense the softener comes thru the lid into the dispenser probably during the first rinse.Is there a way to take the lid liner out to check for some kink or blockage from the inlet to where it gets dispensed or is there some other problem?Also,do you know a site where I can download the service manual for free?
