Motor fails to rotate the diverter disc, preventing water from reaching upper or lower spray arms — resulting in food residue left on dishes after a full cycle.
A clicking, grinding, or repetitive mechanical noise during the wash cycle indicates the diverter motor is stuck, worn, or has suffered internal mechanical failure.
A cracked motor housing or degraded shaft seal allows water to escape behind the lower access panel and pool at the base of the dishwasher.
The dishwasher's control board detects that the diverter motor is not receiving or responding to its voltage signal, triggering water-distribution-related fault codes.
The diverter motor fails to switch between wash zones (lower, upper, turbo), causing only one spray arm to receive water or none at all, reducing cleaning effectiveness.
💡 Pro Tip: Is Your Diverter Motor the Problem?
Your part is likely the culprit if you notice any of the following:
⚠️ Dishes — especially on the upper rack — come out dirty or still have food residue after a full cycle
⚠️ Unusual clicking, grinding, or lawn-mower-like noise that starts shortly after the wash cycle begins
⚠️ Dishwasher displays error codes related to water distribution or diverter function
⚠️ Water leaking from the base of the dishwasher, near the center sump area
🔬 Quick bench test: With the motor removed, apply 120VAC across the two terminals. If it doesn't rotate smoothly in both directions, it has failed. Also inspect the sump grommet (WPW10195677) — a cracked seal is often found alongside a failed diverter motor and should be replaced at the same time.
