Cold water issue...please help!!

I have a LG Washer. On all the temps it only will spit out hot water and not cold. Not even warm. I took off both hoses and cleaned the filters because when the floor people came in to put in wood laminate flooring they were scraping the concrete and created "concrete dust" and a little got in there…not much cause the filters were not that dirty. However, this did not help the problem. Still just get hot water. Can anyone please tell me what it could possible be. Everything else is working just fine. It drains and spins just perfectly.

Thanks!
