Kenmore 66517339400 undercounter dishwasher Parts

Your Kenmore dishwasher model number is printed on the model and serial number label, which is typically located inside the door opening on the inner door frame or along the tub edge. For Kenmore units like model 66517339400, the model number often begins with 665.

Where to look first (fastest checks)

• Open the dishwasher door and look around the inner door frame.
• Check the tub wall near the door opening.
• Look along the top or side edge of the door.
• If the label is worn, use a flashlight and view it from an angle.
• Write down both the model and serial numbers; you need both for parts and service.

If you still cannot find the label

Sometimes the label is hard to see due to detergent residue or wear. Use these steps:

• Wipe the area with a damp cloth and mild detergent; dry it and re-check.
• Look for a metal plate or a white sticker with a barcode.
• Check your paperwork and the 66517339400 owner's manual.
• If the unit was recently installed, the 66517339400 installation guide also references keeping the model and serial numbers handy for service calls.

Why the exact model number matters

Kenmore dishwashers can look similar but use different parts (door seal, latch, inlet valve, racks). Matching the full model number ensures the correct fit and helps troubleshooting steps line up with your control panel and features.

Yes. We still carry replacement parts for many Kenmore dishwashers, including Kenmore model 66517339400. The key is matching parts by the full model number so you get the correct fit for common repairs like leaks, poor washing, or a door that will not latch; your 66517339400 owner's manual also helps confirm what your dishwasher uses.

How to find the right part fast

Use the model number 66517339400 (from the rating label) and then match the symptom to the part category.

• Confirm the full model number before ordering (Kenmore numbers are easy to mix up)
• Start with the symptom: leak, not filling, not draining, not cleaning, door will not close
• Check wear items first: seals, spray arm hardware, rack rollers, drain hose
• Compare your existing part visually (mounting points, ports, electrical terminals)
• If you are installing a water line or drain line, follow the clearances and connection steps in the 66517339400 installation guide

Yes, repairing a Kenmore dishwasher like model 66517339400 is worth it when the fix is a common wear item (seal, latch, hose) or a straightforward leak or drainage issue; those repairs usually cost far less than replacement and restore reliable cleaning.

Quick way to decide (cost vs. age)

Use this simple rule of thumb for an undercounter dishwasher:

• Under 10 years old: repair is usually the better value
• 10 to 15 years old: repair if the problem is minor and parts are affordable
• Over 15 years old: replace if the repair involves major electrical or motor components

What’s wrong?	Typical repair type	Usually worth it?
Door leaking	Door seal or alignment	Yes
Won’t latch or start	Door latch/switch issue	Yes
Not draining	Drain hose, air gap cleaning, clogs	Yes
Poor wash	Spray arm or seals	Often
Loud grinding, no wash action	Pump/motor issue	Sometimes

Repairs that are commonly cost-effective on 66517339400

These are frequent, practical fixes that often bring a dishwasher back to normal operation:

• Replace a leaking door gasket with the dishwasher door seal WPW10509257
• Fix a door that will not close or start by replacing the dishwasher door latch WP3380854
• Address drainage problems by checking for kinks or blockages and replacing the dishwasher drain hose WP3374077 if needed
• Improve wash performance by inspecting the spray system and replacing worn seals such as the dishwasher lower spray arm seal WP3376846
• Stop overfilling or leak symptoms by inspecting the float and replacing the dishwasher float assembly WP3376397 if it sticks or leaks

Don’t overlook maintenance (it changes the math)

A “repair” is sometimes just maintenance. For example, the manual explains that a drain air gap (an external plumbing device) should be cleaned periodically to prevent backup and drainage issues. Follow the steps and diagrams in the 66517339400 owner’s manual.

Why it matters

Small problems like leaks, poor draining, or a door that will not latch can lead to bigger issues (water damage, repeated cycle failures, and poor cleaning). Fixing the root cause early usually keeps the dishwasher dependable for years.

On Kenmore dishwasher model 66517339400, installing the lower spray arm is usually a quick, tool-free job: seat the arm on the hub, secure it with the correct retainer (nut), then confirm it spins freely and does not hit the bottom rack. Use the 66517339400 installation guide for safety and access tips.

Before you start (safety and setup)

• Turn off power at the breaker; we do this anytime we work inside the tub.
• Do not lean on the open door; it can tip and cause injury.
• Pull the bottom rack out to give yourself room.
• Place a towel over the pump area to prevent small parts from dropping in (a common install-guide tip).

Install the lower spray arm

1. Remove the bottom rack.
2. Set the lower spray arm onto the center support so it sits flat.
3. Install the retainer and tighten it snugly by hand.
4. Spin the arm by hand; it must rotate smoothly without rubbing.
5. Reinstall the bottom rack and check that tall items do not block rotation.

Helpful parts for this model

• If the retainer is missing or stripped, replace the dishwasher spray arm nut WP8268873.
• If you see leaking at the arm base, replace the dishwasher lower spray arm seal WP3376846.

Quick checks after installation

• Run a short cycle and listen for clicking or thumping (a sign the arm is hitting dishes).
• Confirm the bottom rack is installed correctly; misalignment can interfere with rotation.
• Load large pans at the sides and back so water can reach the detergent dispenser area.

Common symptoms and what they point to

Symptom	Most common cause	What we do next
Arm will not spin	Dishes blocking, arm not seated	Reload, reseat arm, recheck nut
Poor cleaning on lower rack	Clogged spray holes, blocked rotation	Clean holes, verify free spin
Water leaking near arm base	Worn seal	Replace lower spray arm seal

Why it matters

The lower spray arm drives most of the wash action on the bottom rack. If it is loose, blocked, or leaking at the hub, you get poor cleaning, noise, and wasted water pressure.

A Kenmore Elite dishwasher typically lasts 10 years with normal household use. Regular cleaning, correct loading, and fixing small leaks or draining issues early helps your dishwasher reach that full service life; our 66517339400 owner's manual covers the maintenance routines that matter most.

Typical lifespan and what affects it

Most dishwashers land in a fairly tight range; the biggest difference is maintenance and water conditions.

• Typical service life: about 10 years
• Hard water shortens life by building scale on the heater and spray system
• Heavy daily use wears the pump, door latch, and racks faster
• Poor draining strains the motor and can cause odors and residue
• Leaks (door seal, hoses, tub area) should be corrected immediately

Quick maintenance checklist (best payoff)

These steps prevent the most common wear issues in an undercounter dishwasher like Kenmore model 66517339400:

• Clean the filter and sump area on a routine schedule
• Rinse heavy food soil off dishes before loading
• Run hot water at the sink before starting a cycle (improves wash performance)
• Use rinse aid to reduce spotting and improve drying
• Inspect the door perimeter for gaps, tears, or flattening

Parts that commonly drive “end of life” decisions

When performance drops, these are the parts we see most often in play.

Symptom	Common cause	Example part for this model
Door won’t latch or starts then stops	Worn latch	Dishwasher door latch WP3380854
Leaks at the door	Flattened/torn seal	Dishwasher door seal WPW10509257
Poor wash coverage	Spray arm or mount wear, clogs	Dishwasher upper spray arm mount WP8539324
Won’t fill or fills slowly	Inlet valve issue	Valve-inlt W10844024

Why it matters

Knowing the expected lifespan helps you decide whether to repair or replace. If your 66517339400 is near the 10-year mark and needs a major repair (like a pump motor), a targeted fix plus better maintenance can still buy meaningful time, especially if the tub and inner door panel remain leak-free.
