Hi,Welcome to Just Answer, My name isXXXXX will be helping you with your appliance issue today.
Give me a few minutes to look at the diagrams and get you instructions on how to replace this, do you need to replace the whole assembly? Is it the main pump assembly for the drain pump assembly you need to replace?
Is the pump assembly accessed from underneath the machine or through the back?
On these once you have the machine out it's near the back but you can get to it through the side once the machine is out, if it's possible to lay the machine on its back once you get it out if you have enough wire and drain hose to do that it's much easier to replace it, it's not a very hard job once the machine is removed from the cabinets, actually it's pretty easy, hope this helps, thank you and have any other questions feel free to ask, thanks again, Bryan
