If your washing machine is starting to make strange noises, or isn't draining properly, it may be time to replace the pump. This can be a relatively easy repair for a do-it-yourselfer, and will only cost about $30-$60 for the part.
Before you begin, make sure you have disconnected the washing machine from its power source. Then, remove the front panel of the machine so you can access the pump. The pump will be located near the bottom of the machine, and will usually be held in place by two screws.
Once you have removed the old pump, simply install the new one in its place and screw it in securely. Finally, reattach the front panel of your washing machine and plug it back in. Your machine should now be running as good as new!
