My Whirpool wtw7500gc0 is not filling with water. After a while in the cycle it displays the long fill error code. Its not a problem with drainage but with getting water in. I checked the hoses and there is very good pressure. It have a faucet ability inside where you can press a button to let water in and that works. It is just in the cycle that water doesnt get let in. I checked that current will go through either side of each inlet valve prong and they do allow current. What do you think it could be? Thanks!
