Joan for Model Number Gsd5330d01ww

Answer Hello Joan, The spray arm hub is actually the only part needing replacement, but since the spray arm hub is not available without the complete assembly, you will have to order the complete lower spray arm assembly WD22X10017. The reason to spray arm will not longer spin is that the retaining tabs that broke off keep the spray arm from being lifted by the water pressure. When the water pressure is applied, the spray arm is hitting the bottom rack and cannot turn.

Answer Hello Chris. Here are the instructions from the manufacture. Hope this helps. To remove the lower wash arm, you will need to insert a screw driver into the tabs under the spray arm, and unscrew the lower spray arm assembly. These are right handed threads. Reinstall in reverse order.

Answer The sleeve on the bottom of the spray arm unscrews from the sump assembly.
