Hot water was not entering the machine, but cold water flowed smoothly

1. Turned off water to washing machine.
2. Used plyers to disconnect the hoses at the back of the washer.
3. Unscrewed old inlet valve from back.
4. Opened top panel of washer and disconnected hose running to wash basin.
4. Lifted the old unit out and unplugged electrical wiring.
5. Reverse above and you're finished!
If you're reading this you can probably do the repair.
Saved myself $500+ on a new washing machine. Wife is happy.
