The lower spray arm doesn't spin. The upper one works fine. I have disassembled the bottom and nothing seems to be clogged. Any suggestions on what it can be and what to replace if need be. I have read that the this same problem was fixed with replacing the vario motor.
ANSWER Hello Bobby,
YOu will want to make sure that your check valve MJX32862501 is not stuck and is operating properly. The check valve alternates the spray from lower to upper spray arms. If the check valve appears to be ok it is connected to the the diverter motor 4681ED3001D that you would want to replace.
