HOW CAN I FIX MY KENMORE WASHING MACHINE?

THIS IS A KENMORE WASHER AND I ONLY USE COLD WATER TO WASH MY CLOTHES. HOWEVER, THE WATER COMES IN VERY SLOWLY. IT TAKES ABOUT 2 HRS. TO WASH A LOAD OF CLOTHES. I HAVE TAKEN OUT THE SCREEN WHERE THE HOSE HOOKS TO THE FAUCET AND IT STILL DOESN'T WORK ANY BETTER. I STUCK MY FINGER IN THE HOLE WHERE THE WATER GOES IN THE WASHER AND IT FEELS AS IF THERE IS SOMETHING THERE LIKE A FILTER BUT NOT SURE WHAT IT IS. ANYONE HAVE ANY IDEAS HOW TO REPAIR?
