Kenmore 66515795790 undercounter dishwasher Parts

No. On Kenmore dishwasher model 66515795790, the lower spray arm is a core wash component; running without it causes poor cleaning and can let water spray in unintended directions inside the tub, increasing the chance of leaks and damage.

What to do instead

• Reinstall the lower spray arm before running any cycle.
• Confirm nothing blocks spray arm rotation (tall pans, utensils, or a shifted rack).
• Check the spray arm holes for clogs; rinse under hot water and clear debris.
• Make sure the retaining hardware is present and snug.
• If the arm is cracked, warped, or won’t stay attached, replace it.

Quick checks (most common causes)

Symptom	Likely cause	What we recommend
Dishes dirty on bottom rack	Lower spray arm missing or clogged	Reinstall and clean the arm; verify free rotation
Thumping or scraping noise	Arm hitting dishes or rack	Reload so items don’t interfere with rotation
Water pooling or odd spray pattern	Arm not seated or nut loose	Reseat arm and tighten the spray arm nut

Parts that commonly apply

If you need replacement parts for the lower spray arm area, these are common for this model:

• Spray arm 675808 (lower spray arm)
• Dishwasher spray arm nut WP9742945 (retains the spray arm)
• Dishwasher lower spray arm seal WP3376846 (helps prevent leaks at the spray arm connection)

Why it matters

The lower spray arm provides the wash coverage for the bottom rack and helps drive overall circulation. When it is missing or not turning freely, the dishwasher can’t distribute water and detergent correctly, so cleaning performance drops and internal splashing can increase.

Yes. On Kenmore dishwasher model 66515795790, you can replace the rubber door seal (door gasket) by pulling the old seal out of the channel, cleaning the sealing surface, and pressing the new seal in evenly so the door closes and latches without gaps. Use the steps in the 66515795790 owner's manual for model-specific guidance.

What to do before you start

• Turn off power at the circuit breaker.
• Turn off the dishwasher water supply.
• Open the door and remove the racks for easier access.
• Avoid leaning on the open door; it can tip if the dishwasher is not fully secured.
• Wipe the inner door edge and tub lip clean and dry.

Basic replacement steps (typical for this Kenmore style)

1. Start at a top corner and gently pull the old gasket straight out of the tub channel.
2. Clean the channel with warm water and mild detergent; remove soap film and debris.
3. Press the new gasket into the channel starting at the top center, working evenly down both sides.
4. Close the door and latch it; let the gasket “set” for a few hours.
5. Run a short cycle and check for leaks around the door.

If you still see leaks after replacing the seal

• Confirm the door is closing tightly and latching; a worn latch can mimic a bad gasket.
• Check for a warped inner door edge or heavy buildup on the tub lip.
• Make sure the gasket is fully seated and not twisted at the corners.
• Verify the dishwasher is level and properly mounted (movement can break the seal).

Symptom	Most common cause	What to check next
Drips at bottom corners	Gasket not seated	Re-press corners into channel
Water at top of door	Door not latching	Inspect dishwasher door latch WP3380854
Random leaks mid-cycle	Oversudsing or spray issue	Use correct detergent; inspect spray arms

Why it matters

A properly seated door gasket keeps wash water inside the tub, protects the floor from water damage, and helps the dishwasher maintain correct wash pressure for better cleaning.

Your Kenmore dishwasher’s model number is printed on the model and serial number label inside the door area. For model 66515795790, look along the tub opening edge (commonly the right side) when the door is open; write down both the model and serial numbers.

Where to look on the dishwasher

Check these common label locations first:

• Along the right side of the tub opening (most common for this style)
• Along the left side of the tub opening
• On the top or side edge of the inner door
• Near the frame behind the door seal area

For diagrams and exact label callouts, use the 66515795790 owner's manual.

What to record (and why)

To reset a Kenmore Ultra Wash Quiet Guard dishwasher like model 66515795790, we cancel the current cycle and restart a new one. In many cases, simply closing the door fully and selecting a fresh cycle restores normal operation after a pause, stop, or control confusion.

Quick reset steps (most common)

• Press Cancel/Drain (or the model’s cancel function) and let it pump out for about 1 to 2 minutes.
• Open the door, then close it firmly until it latches.
• Select Normal Wash (or your preferred cycle) and any options.
• Press Start (or turn the timer knob to start, if your control uses a knob).
• Wait a few minutes to confirm it begins filling and washing.

If it still will not start after a reset

The manual troubleshooting guidance for this style of Kenmore dishwasher focuses on door latch, power, water supply, and motor overload reset.

• Confirm the door is closed and securely latched.
• Check the home breaker or fuse supplying the dishwasher.
• Make sure the dishwasher shut-off valve is turned on.
• If the motor overloaded, allow a few minutes for the motor to reset automatically.
• If it will not fill, press the overfill protector (float) down to be sure it moves freely.

Delay Wash can look like a “won’t start” problem

If Delay Wash is set, the dishwasher intentionally waits before running. On this model family, delay can be set for up to 5 hours.

What you see	What it usually means	What to do
Timer not advancing	Door not latched	Re-close door until it latches
Delay indicator on	Delay Wash is set	Cancel delay, then restart cycle
Long pauses	Water heating delays	Let it continue; this is normal

Why it matters

A proper reset clears a stuck cycle and helps you avoid unnecessary part replacement. If the dishwasher still stops, the symptom often points to a door-latch issue or a fill problem (float or inlet water supply).

Yes, repairing a Kenmore dishwasher like model 66515795790 is usually worth it when the problem is a wear item (seal, latch, spray arm, fill valve) and the repair cost is clearly less than replacing the dishwasher. It is less worth it when a major drive component fails and the repair approaches replacement cost.

Quick decision checklist

• If the dishwasher is under 10 years old, repairs are typically the better value.
• If the issue is a leak at the door, start with the owner's manual checks and consider a new dishwasher door seal WPW10509257.
• If it will not fill or fills slowly, the inlet valve W10844024 is a common fix after verifying water supply.
• If it will not latch or start, a worn dishwasher door latch WP3380854 is a frequent cause.
• If cleaning is poor, a clogged or damaged spray arm 675808 can be the culprit.
• If the repair involves a pump motor and the dishwasher is older, compare the total repair to replacement.

Typical repair cost vs. replacement (rule of thumb)

Repair type	Common symptoms	Usually worth it?
Seals, latch, spray arm, fill valve	Leaks, won’t start, poor wash, no fill	Yes
Drain hose or clamps	Leaks under unit, draining issues	Yes
Pump motor or timer	Loud grinding, no wash action, cycle problems	Depends on age and total cost

Why it matters (and what the manual tells us)

Your Kenmore dishwasher documentation includes warranty coverage that can affect the value equation: a full one-year warranty and additional limited coverage on parts of the wash system (motor, pump, spray arms, seals, gaskets) for a longer period, depending on purchase date and use. Use the owner's manual to confirm what applies to your unit and to follow the recommended troubleshooting steps before buying parts.

Practical next steps before you decide

• Check for standing water, leaks at the door, and obvious hose drips.
• Listen for grinding or crunching; the manual notes this can happen if a hard object enters the wash module.
• Confirm the door closes firmly and the latch engages.
• Verify the hot water supply is on and the shutoff valve is fully open.
• Price the likely part(s) and compare to the cost of a new dishwasher.

On Kenmore model 66515795790, the filter area is in the bottom of the tub under the lower spray arm, as part of the ULTRA WASH soil removal module. You typically access it by removing the lower rack, then lifting off the lower spray arm and its mount to reach the filter basket area.

How to access the filter area

1. Turn off power at the breaker (recommended) and open the door.
2. Pull out and remove the lower rack.
3. Remove the lower spray arm and the spray arm mount.
4. Look directly beneath the spray arm area for the filter basket/soil collection area in the ULTRA WASH module.

For diagrams and part locations, use the 66515795790 owner's manual.

What you will see in the bottom of the tub

Most Quiet Guard style Kenmore dishwashers use a soil removal system that includes a grinder and a soil collection area rather than a large, twist-out cylindrical filter.

Common items in this area include:

• Lower spray arm
• ULTRA WASH module (soil removal system)
• Overfill protector (float)
• Water inlet opening in the tub wall
• Heating element

Quick troubleshooting if cleaning does not help

If you still have poor cleaning after clearing debris from the filter area, check these common causes:

• Spray arm holes clogged or spray arm not spinning freely
• Lower spray arm seal leaking or out of place
• Low fill (water not reaching the proper level)
• Door not latching fully, cycle interruptions
• Heavy soil buildup in the pump or grinder area

Related parts that often matter

Symptom	Part to inspect	Example part for this model
Poor wash coverage	Lower spray arm	Spray arm 675808
Leaks at spray arm base	Lower spray arm seal	Dishwasher lower spray arm seal WP3376846
Door leaks	Door seal	Dishwasher door seal WPW10509257

Why it matters

Keeping the filter basket and soil removal area clear helps maintain water flow through the pump, improves spray pressure at the upper and lower spray arms, and reduces redepositing food soil on dishes.
