Since you have a Direct Drive washer, check the screen at the valve, you must pull the machine away from the wall and remove the hose from the machine and not the faucet. If you see a build up on the screen, clean with a toothbrush only! DO NOT REMOVE SCREEN OR DAMAGE TO THE VALVE WILL OCCUR!
Turn on water though the hose to make sure you have enough water pressure going through, if that checks out OK and the valves screens are clear, then the valve may need to be replaced.
P.S., check and see if screens are placed on the faucet end too!!!
