Sometimes when washing clothes, some garments end up getting stuck in the washer. This is especially true of smaller garments such as bras and socks. Getting a sock stuck in the drum of your washing machine is due to the small space between the bottom of the agitator and the bottom of the drum. Usually the sock is wound around the agitator and near to impossible to pull out of the tub. Removing the stuck sock does require you to disassemble parts of the washing machine.
Unplug the washing machine power cord from the wall outlet. Open the washing machine lid. Look at your agitator to determine how it comes out of the washing machine. Some manufacturers use a set screw on the side of the agitator. Others use a bolt in the centre of the agitator.
Turn the set screw counterclockwise with an Allen wrench if your agitator has a set screw on the side.
Remove the fabric softener dispenser from the top of the agitator if you do not see a set screw. The dispenser usually just pulls off with your hands, although some require prying off with a flathead screwdriver.
Pull the inner cap out of the agitator with your hands. Loosen and remove the bolt in the centre of the agitator with a socket wrench.
Grab the bottom of the agitator and lift it up just enough to give you room to unwind the sock. Unwrap the sock from around the agitator inner shaft and remove the sock. Push the agitator back down and secure it in the reverse order you loosened the agitator. Plug the washing machine power cord back into the outlet.
