No Water coming into dishwashewr

there is a valve that looks like a float in the bottom of your dishwasher that floats up when the water level is high enough and it cuts off the water. When the level drops it falls back down turning the water back on. Food and grime will cause it to stick in the upright position and keep the water off. Pull the bottom tray out and reach in and gently push it down and try again. If it works clean thoroughly so it doesn't stick in either direction. Stuck open is worse than closed as it will fill the washer with water and flood your floor if you're not careful. Super-easy fix. Let me know if it doesn't help and we'll go from there
