LG WM2277HW washer not filling with water - LG WM-2277HW Front Load Washer

I own the same washer. First see if you are getting the "IU" or any other error code. I would do the following

1) Check to make sure the water supply valve, where the hoses connect (just bear with me!) is on. hoses should be "stiff" with water pressure.
2) Check for a link in the hoses which may be blocking water flow
3) Unplug the machine
4) Remove the water supply hoses at the machine end.
5) Remove the plastic orange and blue "screens" and check for blockage
6) Clean and reinstall screens and hoses, make certain all connections are tight
7) Turn on water supply.
8) put load in washer and turn on the run normal cycle
9) Listen for the water valves to open. If you down hear valve opening, it could be a bad valve
10 Check washer to see if water is entering
11) If none of these solves the issue..call for service.

Good Luck!
