I have the above mentioned dishwasher. When I came home today my wife noticed the door almost fell to the floor. I took off the bottom dishwasher plate and saw a white piece of plastic on the floor and a piece of white rope frayed and not connected to anything. I googled this topic and saw people suggesting it might need a door balance link kit. Does this seem correct? Would anyone know the part number for this model? Is this fairly easy for a basic homeowner to replace? Thank you.
