well if the machine is not filling, the valve is good, the float is good then it can only be the timer, if you get the part from the link I supplied and this does not fix the problem you can return the part even after it has been installed. My best guess over the computer is that the timer is shot because this kit includes a float and switch.
The part should come with installation instructions, if not it's a simple matter of opening the door taking the screws out around the inner liner behind the control panel, lift the control panel out, remove the knob, take the screws out behind the knob then switch timers.
The fact it is a kit to repair the water system it will come with full instructions.
