First thing I\'d do is inspect the hose. Remove it from the washer entirely (use a bucket to contain stray water) and visually inspect / wash out with a water spray nozzle like a garden or kitchen hose. From the sounds of it, however, I doubt the hose is the issue, but you\'ll want to rule that out first. If the hose checks out, then either the pump or the belt is the issue. Pumps tend to get clogged over time--I\'m not familiar with yours, but yours may be able to be opened (if so, it\'ll have screws holding it together) and you can remove it and clean it out. If it\'s clogged and a sealed unit, you just get a new pump. If the pump looks ok, the belt might be slipping, but if that were the case you\'d probably have more issues. Still, depending on the age of the unit, you may want to replace the belt now since you\'re going to have to remount the belt after playing with the pump. I use repair clinic for my guides while doing work, and if I can\'t find the part locally I use them to supply the parts. Check out this page for more help:

Of course, if the idea of taking apart your washer totally freaks you out, go hire a repair person. :) But they\'re not all that hard, honestly--more of just a pain to take care of, since this\'ll probably be your first washer tear-down. Best of luck, and watch those videos at repair clinic--they\'re pretty helpful!
