Little cold water to washing machine
Shut off the power to the machine at the circuit breaker, unplug the machine, turn off the valves at the wall, slide the macchine out from te wall far enough, unthread the hose from the machine, put the hose in a bucket, and turn the valve back on. If you get a good supply of water, the problem is in the machine. If not, disconnect the hose from the valve on the wall, and see if you get a good supply of water from the valve. If so, the problem is in the hose, and if not, the problem is in the supply line.
