With out being there to test it makes it near impossible to give a reason. I presume you have checked the obvious and made sure tap is fully open and hose from cold tap is on the cold inlet and hot connected to hot inlet. Apart from that, it could be a faulty inlet valve or faulty control module. Does it not fill on either hot or cold? When you say it agitates you mean the bowl rotates for filling. Agitates is what happens after the water has filled & the agitator goes forward & backward to wash the clothes.
