It is possible that there is a problem with the cold side of the water valve.
Turn off the cold water tap.
Undo the hose at the machine and run some water into a pail, to be sure hot water is reaching the machine.
Some hoses have a screen filter built into the sealing washer at the tap, also hoses can de-laminate internally and cause problems.
If OK
Look into the machines cold water valve and check that the filter screen built into the input side of the valve is clean.
If not, clean it. Do not permanently remove it as it is there to keep crud out of the valve which could hold the valve open and cause a flood.
If OK
Reattach the hose, unplug the unit and switch the wires from the hot to the cold and vice versa.
Plug it in and give it a try.
If you still only have hot water, the water valve needs to be replaced.
If it fills with cold water then you know the problem is not the cold water valve, probably the temperature selector switch.
