Kenmore 66516795790 undercounter dishwasher Parts

Kenmore dishwasher racks are sometimes interchangeable, but only when the rack’s size, wheel/track style, and spray clearance match your exact dishwasher. For Kenmore model 66516795790, the safest approach is to replace the rack with the correct model-matched rack to ensure smooth sliding and proper wash coverage.

What “interchangeable” really means

Even when two racks look similar, small differences can prevent a good fit.

• Track and wheel design must match so the rack rolls smoothly
• Rack width and depth must match the tub so it does not bind
• Spray arm clearance must stay correct so the arm does not hit dishes or the rack
• Stop positions must align so the rack does not slide off the rails
• Mount points for accessories (like a silverware basket) must line up

Quick fit check before you buy

Use this checklist to confirm compatibility on 66516795790:

• Measure the old rack’s overall width and depth
• Compare the roller location and roller diameter
• Confirm the rack engages the same slide rail/track style
• Verify the rack does not interfere with the lower spray arm and its hardware
• Confirm your accessories fit, such as the silverware basket W10807920

Common rack-related issues and the part that usually fixes it

Symptom	Most common cause	What to check first
Rack feels “wrong” or won’t slide	Track/roller mismatch	Rail shape and roller position
Rack falls off the rail	Missing/worn stop or rail issue	Rail ends and rack alignment
Poor cleaning after rack swap	Spray arm blocked or hitting	Lower spray arm clearance
Dishes come out dirty on bottom	Spray arm not spinning freely	Arm spins by hand with rack loaded

If you suspect spray interference, inspect the lower spray arm and related hardware such as the spray arm 675808 and dishwasher lower spray arm seal WP3376846.

Why it matters

A rack that does not match the tub geometry can block the spray pattern, prevent the spray arm from rotating, or cause the rack to derail. Using the correct rack for Kenmore 66516795790 protects wash performance and helps prevent repeat failures.

Your Kenmore dishwasher’s model number is printed on the rating label, typically located on the inside edge of the door opening. Once you find it, match that number exactly (for example, 66516795790) when ordering parts or troubleshooting.

Where to look for the model number

Check these common label locations on Kenmore undercounter dishwashers:

• Inside the door, along the left side of the tub frame
• Inside the door, along the right side of the tub frame
• Along the top edge of the door (visible when the door is open)
• On the side of the inner door panel near the latch area

What to write down (and why)

Record the information exactly as shown on the label:

• Model number (this is what parts diagrams and part fit use)
• Serial number (helps identify production run details)
• Any suffix letters or extra digits (they can change part compatibility)

Quick guide: model vs. serial

Item on label	What it’s used for	Example
Model number	Picking correct replacement parts	66516795790
Serial number	Identifying manufacturing details	Varies

Why it matters

Kenmore dishwashers often look similar across multiple model series, but internal components like the inlet valve, door latch, and spray arm can differ. Using the exact model number helps ensure the part you choose fits and performs correctly.

If the label is hard to read

Try these steps to make the print legible:

• Wipe the label gently with a damp cloth and mild dish soap
• Use a flashlight at an angle to reduce glare
• Take a close-up photo and zoom in
• Copy the number exactly, including any leading zeros

On Kenmore dishwasher model 66516795790, impeller removal typically requires pulling the dishwasher, accessing the pump area from below, and removing the fastener that retains the impeller on the motor shaft. We recommend replacing any worn pump seals during reassembly to prevent leaks.

Before you start (safety and prep)

• Turn off power at the breaker (dishwashers use 120 VAC).
• Shut off the water supply valve under the sink.
• Remove the toe-kick panel to access the underside.
• Place towels or a shallow pan under the pump area.
• Take photos of wire and hose routing for correct reassembly.

Impeller removal steps (typical Kenmore pump design)

1. Disconnect power and water, then pull the dishwasher out far enough to work safely.
2. From underneath, locate the pump and motor assembly.
3. Remove the lower access components as needed to reach the impeller housing.
4. Remove the impeller retainer (commonly a Phillips screw or nut). On many designs, the retainer uses reverse threads, so it loosens by turning clockwise.
5. Lift or pull the impeller straight off the motor shaft. If it is stuck, wiggle gently; do not pry against plastic pump housings.
6. Inspect the impeller blades and hub for cracks, and check the shaft area for debris.

Parts we commonly replace while you are in there

Symptom you are preventing	Part to inspect/replace	Example from this model
Leaks at pump or heater pass-through	Rubber seals and washers	Dishwasher heating element rubber washer WP717273
Poor wash due to spray issues	Spray arm and related hardware	Impeller 675806
Water fill problems after reassembly	Water inlet valve	Inlet valve W10844024

Why it matters

A worn or damaged impeller reduces water circulation, which leads to poor cleaning, gritty residue, and longer cycle times. Correct retainer direction and careful handling prevent cracked housings and repeat leaks.

Quick checks after reassembly

• Run a short cycle and watch for drips under the pump.
• Confirm strong spray action (listen for steady wash sound).
• Verify the unit fills and drains normally.

Yes, repairing a Kenmore dishwasher model 66516795790 is usually worth it when the problem is a wear item (seal, latch, spray arm, inlet valve) and the repair cost stays well below the price of a replacement. If the repair involves a major drive component, the value depends on total cost and overall condition.

Quick decision checklist

• Fix it when it leaks at the door, won’t latch, fills slowly, or cleans poorly due to spray issues.
• Think twice when the repair involves the main wash motor or multiple failures at once.
• Fix it when racks and baskets are the main complaint (cheaper than replacing the whole unit).
• Replace it when rusted tub, repeated leaks, or chronic electrical issues show up.
• Fix it when you can DIY safely and the dishwasher is otherwise reliable.

Common repairs that are typically “worth it”

These are frequent, targeted fixes on an undercounter dishwasher like this Kenmore:

Symptom	Likely part to check	Why it’s a good repair
Water on floor at the door	Dishwasher door seal WPW10509257	Stops leaks without major disassembly
Door won’t stay closed	Dishwasher door latch WP3380854	Restores safe, consistent operation
Poor cleaning, food left behind	Spray arm 675808	Improves wash coverage quickly
Not filling or fills slowly	Inlet valve W10844024	Fixes water supply control issues

When repair may not make sense

A high-cost repair can outweigh the benefit, especially if other parts are worn.

• Loud grinding and no wash action that points to the main motor: pump motor W10428773
• Multiple symptoms at once (leak plus no-fill plus poor wash)
• Heavy corrosion, cracked sump area, or repeated flooding events

Why it matters

A dishwasher that seals, fills, and sprays correctly can run for years with routine maintenance. Targeted part replacement (like a door seal, latch, or spray arm) often restores performance without the cost and hassle of a full replacement.

Water in the bottom of your Kenmore dishwasher model 66516795790 is usually caused by a drain restriction (food debris in the sump area, a kinked or clogged drain hose, or a blockage at the sink/disposal connection). A small amount of water can also remain to keep seals from drying out.

Quick checks we recommend first

• Cancel the cycle and run Drain (or Cancel/Drain) to see if the water level drops.
• Remove the lower rack and check the sump area for labels, glass, bones, or heavy debris.
• Inspect the drain hose routing under the sink for kinks, crushing, or a sag that traps water.
• Check the sink drain or garbage disposal inlet where the dishwasher hose connects for buildup.
• If you recently installed a new disposal, confirm the dishwasher inlet plug was removed.

Parts that commonly fix “won’t drain” symptoms

If the checks above do not restore draining, these model-matched parts are common fixes:

Symptom you notice	Most likely area	Model-matched part to consider
Water never drains, no movement	Drain path blocked or hose issue	Dishwasher drain hose WP3374077
Water overfills then stops, may drain poorly	Float stuck or switch not actuating	Dishwasher float assembly WP3376397
Fills slowly or odd fill behavior (can affect draining performance)	Water inlet problem	Inlet valve W10844024

Step-by-step: clear the drain path safely

1. Turn off power at the breaker.
2. Pull the lower rack; remove standing water with a cup/towel.
3. Clear debris from the sump area and around the lower spray arm base.
4. Under the sink, disconnect the dishwasher drain hose and check for sludge or a hard clog.
5. Reconnect, restore power, and run a short cycle to confirm strong draining.

Why it matters

Standing water can lead to odors, poor cleaning, and leaks at the door. Fixing the drain restriction early also helps protect the pump and motor from strain.
