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.

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

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

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.

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.

Yes. We still carry replacement parts for many Kenmore dishwashers, including model 66516795790, for common repairs like leaks, poor cleaning, and rack or basket wear. The key is matching parts to your exact model number so the fit and connections are correct.

For this Kenmore undercounter dishwasher, these are examples of in-demand parts that are typically replaced during normal ownership:

• Door leak parts such as the dishwasher door seal WPW10509257
• Wash performance parts such as the spray arm 675808
• Fill and water level parts such as the inlet valve W10844024
• Drain and water routing parts such as the dishwasher drain hose WP3374077
• Loading parts such as the silverware basket W10807920

Use this quick checklist before you buy:

• Confirm the model number on the dishwasher data tag is 66516795790
• Compare the part name and part ID (not just a photo)
• Match the symptom to the system (fill, wash, drain, heat, or door seal)
• Replace related seals/hardware when you disturb a joint (example: spray arm seals)
• If the dishwasher is leaking, check for more than one source (door, hose, pump area)

Kenmore parts availability is strongest when you shop by the exact model number. That prevents returns, reduces downtime, and helps you fix the real cause (for example, a worn door seal versus a drain hose issue).

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.

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

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)

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.

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.

• 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.

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.

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.

• 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.

• 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.

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

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

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.

• 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.

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

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.

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.
