How to Fix / Troubleshooting

Safety first: Disconnect power and water.

Check spray arms first: Remove upper and lower spray arms. Rinse under running water and clear any blocked jets with a toothpick. Ensure they spin freely when reinstalled.
Access diverter assembly: From the bottom of the dishwasher, locate the diverter valve/motor attached to the sump or circulation pump outlet.
Inspect for obstructions: Remove the diverter cover if possible and check for debris preventing movement of the internal disc or flap.
Test diverter motor: With power off, disconnect the motor and measure resistance across its terminals. Compare to service specs; an open circuit indicates failure.
Check wiring: Ensure the harness to the diverter is intact and firmly connected.

If the diverter motor is faulty or the valve body is damaged, replace the diverter assembly. Complex access may warrant a professional repair.
