Hello,
Here are some rough instructions on changing the coupler. You can avoid this by not overloading your washer.
Start by removing the screws in front of the control panel and then flipping the panel back. (Your screws may be hidden by plastic end pieces on each end. Just pull those off to reveal the screws.) Once the panel is back you will see the lid switch harness, just unplug this. You will also see 2 spring clips that must be removed. Stick a straight screwdriver in them and bend them out. Once the clips are out stand in front of the washer and grab the front and side of the cabinet and rock it forward. The whole cabinet tilts forward and you can place it out of the way. You will now see the innards of the washer. To get to the coupler you basically remove the 2 springs clips to the pump and then slide it off the shaft. There is no need to remove the hoses. Disconnect any motor harness connector that is on the motor. Now remove the spring clips attached to the motor and slide the motor out. You will now see the coupler, just remove the 3 pieces and and reverse the what you did to take it apart.
