Whirlpool Dishwasher Diverter Valve Motor Parts — Models & Compatibility

If your Whirlpool dishwasher isn't cleaning the top rack properly — or maybe water's spraying everywhere except where it should — there's a good chance the diverter valve motor has failed. This W11036111 motor controls water flow between the upper and lower spray arms, and when it quits, you'll notice uneven cleaning or strange grinding sounds during the wash cycle. This hub covers compatible models across Whirlpool, KitchenAid, and Maytag dishwashers that use this specific valve motor assembly.

Is This the Right Part for Your Model?

Check your dishwasher's model number before ordering. You'll find it on a sticker inside the door frame (along the top or side edge when you open the door). Match your complete model number against the compatibility list below. This motor replaces part numbers W11412297, W11690882, and AP6980076, so if your old part has any of those numbers stamped on it, you're looking at the right replacement.

About This Replacement Part

The diverter valve motor is the electronic actuator that redirects water pressure between the upper and lower spray assemblies during different wash cycles. When this motor fails, water distribution becomes erratic — sometimes the top rack gets no water at all, other times the lower arm stops spinning. You might hear clicking or humming sounds as the motor tries (and fails) to rotate the diverter disc. This is a direct OEM-compatible replacement that mounts to the circulation pump housing at the bottom of the tub. The motor includes the mounting bracket and electrical connector, so installation involves unplugging the old unit, removing two screws, and reversing the process with the new motor.

Signs You Need This Motor

The diverter valve motor doesn't fail gradually — it usually quits completely. Top rack dishes stay dirty while bottom rack items come out clean (or vice versa). You might notice the dishwasher running quieter than normal because water isn't switching between spray zones. Some units throw error codes related to water circulation. If you hear a buzzing or clicking sound during the cycle but water distribution seems off, the motor's likely seized or the gear teeth have stripped inside the housing.

What's Included

This replacement includes the complete diverter valve motor assembly with mounting hardware and electrical connector. You don't need to purchase additional gaskets or brackets — everything required for installation comes in the package. The motor is factory-calibrated to match OEM specifications for timing and rotation angles.

Installation Overview

You'll need to access the bottom of the dishwasher tub, which means removing the lower spray arm and the pump cover. Disconnect power first (obviously). Unplug the wire harness from the old motor, remove the two mounting screws, and twist the motor counterclockwise to release it from the pump housing. Installation is the reverse: align the new motor's tabs, twist clockwise to lock, secure with screws, and reconnect the harness. Total time is about 30 minutes if you've done this before, maybe 45 if it's your first diverter motor swap.

Repair vs. Replace Decision

These motors aren't designed to be rebuilt — the sealed housing contains electronics and gearing that can't be serviced individually. If your diverter motor has failed, replacement is the only practical fix. The good news is that changing this part is significantly cheaper than paying for a service call or replacing the entire dishwasher. Most techs charge $200-300 for this repair including the part, so DIY installation makes sense if you're comfortable working with basic tools.
