Understanding the Problem
What this part is and why it matters: The W10537869 is the diverter motor assembly used on many Whirlpool, KitchenAid and Maytag dishwashers. The diverter routes wash water between the upper spray system and the lower tub spray. When it fails the dishwasher will often spray only the lower rack (no water to the top), spray arms won't move, make unusual noises, or stay stuck in one position. Step-by-step diagnostic and repair steps: 1) Safety first: Turn OFF the dishwasher's circuit breaker or unplug the unit. Shut off the water supply to the dishwasher if you will be disconnecting any hoses. Confirm power is off. 2) Confirm the symptom: Run a short wash cycle with the door open and watch (or listen) — do you get flow to the lower arm only? Do you hear a clicking/grinding sound where the diverter should operate? If the upper rack never receives water, suspect the diverter. 3) Rule out spray arm, filter, and pump blockages: Remove and inspect both spray arms and the filter/sump area for debris or mineral buildup that could be preventing flow. Clear any obstructions and test again. 4) Access the diverter: Pull out the lower rack. Remove the lower spray arm and the spray arm support assembly (these often pull off or are retained by a nut/screw). Depending on model, you may need to remove the lower tub access cover or the sump cover to reach the diverter motor assembly. 5) Visual & manual check: Inspect the diverter for cracks, broken gears, or jammed plastic. Try to move the diverter vane by hand (when cold and powered off) — if it is stuck or severely loose, it is bad. 6) Electrical check: With power restored only if you are comfortable and safe doing so, put the dishwasher into a diagnostic or a wash cycle and carefully measure for voltage at the diverter motor connector. If there is voltage during the part of the cycle where the diverter should move but the motor does not, the motor is failed. If there is no voltage, the problem may be a control board or wiring issue. 7) Remove the old diverter (replacement instructions): a. Disconnect power (again) and remove the lower rack. b. Remove lower spray arm and any retaining hardware to expose the diverter housing and motor. c. Unplug the electrical connector to the diverter motor. d. Remove mounting screws or clips that secure the diverter motor assembly and carefully pull it out of the tub/sump area. Note orientation of the vane and any gaskets/seals. 8) Install the W10537869: Position the new diverter in the same orientation, seat any seals, secure with screws/clips, and reconnect the electrical connector. Reinstall the spray arm and lower rack. 9) Test: Restore power and run a short cycle. Observe whether water now flows to the upper rack and that the diverter actuates smoothly without noise. 10) Final steps: If the new diverter works, reassemble any panels you removed and confirm there are no leaks. If the diverter still does not receive power, troubleshoot wiring and the control board. Safety note: Always disconnect electrical power before working on the dishwasher. If you are not comfortable testing live voltage, call a qualified technician.
Common Symptoms
No water or reduced water to the upper rack, spray arms not moving, grinding or clicking noises from the diverter area, or dishwasher spraying only the lower rack.
Common Causes
- Failed diverter motor (W10537869) or stripped internal gears
- Debris or mineral buildup jamming the diverter vane
- Wiring fault or control board not sending voltage to the diverter

Helpful Repair Tip
To quickly confirm a bad diverter, run a short cycle and listen for the diverter motor attempting to move; if you hear power to the area but no movement, the W10537869 is likely bad. A continuity check on the motor windings (with power off) can also indicate a failed motor.
Frequently Asked Questions
Can I replace the W10537869 diverter motor myself?
Yes — if you are comfortable with basic hand tools and can disconnect power. Replacement typically takes 30–60 minutes. Follow the step-by-step instructions above and always turn off power before disassembly. If you need to test voltage or control board signals, consider hiring a technician if you are not experienced with live electrical testing.
How much does the W10537869 part cost and does replacing it fix the problem 100% of the time?
The part commonly costs roughly $40–$100 depending on supplier. Replacing the diverter motor will fix problems caused by a failed diverter (no water to upper rack, stuck vane, noisy motor). If the root cause is wiring, a control board fault, or a blockage upstream, replacing the diverter alone may not resolve the issue — diagnose as described above before installing the new part.
