no power to the vavle
I am assuming you checked it with a meter.
Note that the float switch is inline with the valve.
Check for power across the float switch or both the valve and float switch.
If it has 120 volts when the unit should be filling the switch is open.

Could be a bad switch
OR
Could be just that the float needs cleaning (stuck in the up position)

If there is no 120 volts then probably the timer is shot or you have a broken wire.
