We pulled out the lower arm before reading instructions to unscrew it. When doing this we broke the tabs inside. Now the spray arm doesn't seem to move during the cycle. Do the broken tabs cause this to happen? Should I just replace the spray arm assembly?
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.
