No water for ice or water dispenser...

Hi all. Water was off for a day. I had lifted the arm for the icemaker so it would not try to make ice during that time. Before water was turned back on, I replaced the water filter. Once the water was turned back on, I put the bar down for the icemaker and I tried dispensing water. I got what was in the line and then it quit working. No water is coming through the dispenser and no water for the ice maker. I get a lot of sand at times through my faucet and was wondering maybe the intake line is clogged. Or, maybe I got a bad filter. Any ideas would be much appreciated. Thanks.
