DIY Repair Time: 20–40 minutes

Difficulty Rating: Easy to Moderate (2/5) — Requires removing the lower spray arm and filters to access the diverter motor in the sump area. The motor itself is secured with 2–3 screws and one wire harness connector — straightforward to swap. The moderate rating is because accessing the sump area requires removing multiple components (spray arm, filters, covers) and ensuring they're all reinstalled correctly in the right order. No plumbing disconnection required for most models.

  • Top rack dishes not getting clean — food residue, cloudy glasses, stuck-on debris
  • Bottom rack cleans fine but top rack comes out dirty
  • Top rack cleans but bottom rack doesn't (diverter stuck in upper position)
  • Neither rack cleans well — overall poor wash performance
  • Spray arms not spinning — no water reaching one or more spray arms
  • Only one spray arm zone working during the entire cycle
  • Dishwasher runs a full cycle but dishes come out dirty
  • Glasses on the top rack are cloudy or spotted after washing
  • Error code displayed related to diverter or wash system
  • Clicking or buzzing noise from the sump area (diverter motor trying to move but stuck)
  • No noise from diverter during cycle (motor completely dead)
  • Dishes need to be re-washed — inconsistent cleaning results
  • Detergent residue remaining on dishes (insufficient water flow to dissolve and rinse)

Before replacing the diverter motor, check the spray arms themselves. Remove each spray arm and inspect the spray holes for clogs — food particles, mineral deposits, and broken glass fragments commonly block the small holes, reducing water flow. Clean the holes with a toothpick or thin wire. A clogged spray arm mimics a failed diverter because the water is reaching the arm but can't spray out effectively.

Also check the filter system. A clogged fine mesh filter restricts water flow to the wash pump, reducing pressure to all spray arms. Clean the filters thoroughly — this is the most common cause of poor wash performance and is often mistaken for a diverter problem.

If both spray arms are getting water but dishes are still dirty: the problem is likely the wash pump (weak pressure), water temperature (should be 120°F entering the dishwasher), or detergent (old detergent loses effectiveness). The diverter is only the problem when one zone cleans and the other doesn't.

W10843811 Whirlpool Dishwasher Diverter Motor – Fix Your Dishwasher That Won't Clean the Top Rack, Has Poor Wash Performance, Won't Switch Spray Arms, or Displays Error Codes Related to the Diverter

W10843811 Whirlpool Dishwasher Diverter Motor – The direct fix for a Whirlpool dishwasher that won't clean the top rack, leaves dishes dirty on the upper level while the bottom rack cleans fine, has poor overall wash performance, won't switch between spray arms during the cycle, or displays a diverter-related error code. The diverter motor is the small actuator inside the sump that directs pressurized wash water between the lower and upper spray arm zones. Instead of splitting water pressure across all spray arms at once (which weakens cleaning power), the diverter alternates full pressure between zones in a timed sequence — lower spray arm, then upper spray arm, then back — so each zone gets concentrated, high-pressure water for thorough cleaning. When the diverter motor fails, it gets stuck in one position — typically directing all water to the lower spray arm only. The result is a bottom rack that cleans normally while the top rack comes out with food still stuck on dishes, cloudy glasses, and residue. In some cases, the diverter gets stuck directing water to the upper arm only, leaving the bottom rack dirty. A completely failed diverter motor may trigger an error code on the control panel. There is no way to manually override the diverter — it must be replaced. This genuine OEM Whirlpool part directly replaces W10537869. Fits Whirlpool, KitchenAid, Maytag, Kenmore, Amana, Jenn-Air, and Ikea dishwashers. 20–40 minute DIY repair.

✅ Frequently Asked Questions

Why is my dishwasher not cleaning the top rack?

A dishwasher that cleans the bottom rack fine but leaves the top rack dirty is one of the most common complaints — and there are several possible causes:

Failed diverter motor (most likely on newer Whirlpool models). The diverter motor alternates water pressure between the lower and upper spray arms. If it fails in the lower position, all water goes to the bottom spray arm and the top rack gets nothing. This is the most common cause on Whirlpool, KitchenAid, and Maytag dishwashers made after 2013 that use a single wash pump with a diverter system. Replacing the W10843811 diverter motor restores water flow to the upper spray arm.
