Charlie for Model Number ZBD0710N00SS Just like Margie said part 450 clip broke I need to remove and replace. You have several videos one shows the tech just turning this part counter clockwise and this SPRAY ARM SUPPORT/MAIN CONDUCT NOT SURE WHAT IT IS CALLED COMES RIGHT OUT. In an another Video this part 450 lifts right out. Well like Margie says part 450 just turns and turns clockwise and it will not lift out. Anyway my Dishwasher is is a GE ZBD0710NOOSS.
Answer Charlie, the WD18X10009 venturi hub asm. Prt # 450 is no longer available as a separate component. The manufacturer has discontinued the part and replaced it with WD12X10057 / WD12X10057 spray arm water supply tube. To remove the lower spray you need to pull it up while turning it counterclockwise. once the spray arm is removed you need to rotate the hub nut counterclockwise. Lift the hub nut off the fine filter and lift the fine filter off the spray arm hub. Replace the water supply tube and reverse the procedure. Check the dishwasher for operation. Read More...
