GE Dishwasher Diverter Motor/Valve Replacement - Signs & How-To

GE Dishwasher Diverter Motor/Valve Replacement — What This Part Does

The diverter motor and valve assembly in a GE dishwasher sits inside the sump and controls where circulating wash water is routed during the cycle. It redirects pressure between the upper and lower spray arms so each rack gets proper coverage. The assembly includes a motor that positions the diverter, internal seals and a valve body that opens and closes spray paths, and an electrical connector that reports position feedback to the control board.

The diverter fails when seals crack or wear out and leak, when debris or mineral buildup jams the internal mechanism, or when the motor or its feedback sensor stops working. A damaged filter ball in the diverter area or a cracked valve body will also prevent proper water routing. GE treats the diverter as a single assembly, so the repair is always a full unit replacement rather than trying to fix the motor or seals separately.

Signs It Needs Replacing

• Poor wash performance on one rack only Dishes on the top or bottom rack come out dirty while the other rack is clean, because the diverter is stuck and water only reaches one spray arm.
• Dishwasher cycles abnormally or stops mid-wash The control board detects that the diverter is not moving or reporting correct position, so it halts the cycle or skips spray phases.
• Weak or uneven spray from upper or lower arm The diverter valve is leaking internally or not fully opening one path, so pressure is split or lost and one spray arm barely spins.
• Error code related to diverter or water flow The display shows a fault tied to the diverter motor or position sensor, though the exact code name varies by GE model.
• Visible leak or water pooling under the dishwasher Cracked seals or a damaged diverter body allow wash water to escape the sump and drip onto the floor or subfloor.
• Grinding or clicking noise during the wash cycle The diverter motor is trying to move but the mechanism is jammed by debris or the internal parts are mechanically damaged.

How to Replace It

1. Unplug the dishwasher or shut off its circuit breaker, then turn off the water supply valve under the sink.
2. Pull the dishwasher out from under the counter if you need better access to the sump area, and disconnect the water supply line and drain hose as needed.
3. Remove the lower dish rack and lower spray arm, then take out the filter assembly and any cover or shield over the sump.
4. Disconnect the electrical connector from the diverter assembly by pressing the locking tab and pulling the plug straight out.
5. Remove the screws or clamps securing the diverter assembly to the sump body, then rotate or lift the assembly to unlock and remove it from the sump.
6. Inspect the sump seat, main conduit, and filter ball for debris, cracks, or damage, and clean the seat thoroughly before installing the new diverter.
7. Position the new diverter assembly into the sump, rotate or press it to lock it into place, then reinstall the retaining screws or clamps.
8. Reconnect the diverter wiring harness, making sure the connector clicks and locks fully, then reinstall the filter, spray arm, and any covers.
9. Restore water and power, then run a test cycle and watch for proper spray switching on both racks and no leaks from the sump area.

When to Call a Pro

If you are not comfortable working inside the dishwasher sump, if the new diverter still does not solve the wash distribution problem, or if you find additional damage to the pump housing or main conduit, call a qualified appliance technician. A tech can also diagnose control board or wiring faults that might send incorrect commands to the diverter, and they carry the tools to pressure-test the sump for hidden cracks or leaks that would otherwise cause repeat failures.
