Had to remove top took out the screws slide it forward to remove, cut nylon tie holding hoses up, lay dishwasher on back, get cardboard dust cover out of the way, disconnect hoses, remove, mop up water, connect new assembly. Now it works great. I choose number 2 on the challenging part, because I am 71 years old so I had to ask my son for help getting it to lay on it's back.
