water not turning on for washer supply valves
Without seeing the lines, I would say frozen. Sometimes if you can access them, you can tap on them lightly and see if there is a change in the sound from one section to another, follow the pipe all the way from the appliance as far as you can. It it sounds hollow in one section closer to the washer and more solid the other way, you have a blockage of some sort. Try to carefully heat the pipe where it sounds more solid close to the hollow section. You might also be able to "feel" the pipe for hot or cold sections. Usually of the wash basin and machine are close, they feed from the same pipe and if you have water at one and not the other, you have a blockage.
