Kenmore 66515789300 undercounter dishwasher Parts

Common problems on a Kenmore dishwasher like model 66515789300 include not starting, not filling, running too long, poor cleaning from blocked spray, and leaks around the door. Many issues come down to loading, water supply, or a few wear parts that are straightforward to inspect.

Most common symptoms and what to check first

• Won’t start or stops mid-cycle: confirm the door is fully closed and latched, and the cycle is selected.
• No fill or low water: make sure the home water shut-off valve is on; check that the overfill protection float moves freely.
• Runs a long time: verify hot water supply; the dishwasher may extend the cycle while heating.
• Poor wash results: load so spray arms can rotate freely; avoid blocking the detergent dispenser area.
• Leaks at the door: inspect the door seal for gaps, tears, or flattening.

Quick troubleshooting table

Problem	Likely cause	What we recommend
Dishwasher won’t run	Door not latched, power issue	Check latch engagement; check breaker/fuse; review steps in the 66515789300 owner’s manual
Dishwasher won’t fill	Float stuck up, water valve off	Press float down to release; confirm shut-off valve is open
Dishes still dirty	Spray blocked, loading issue	Re-load to keep spray arms clear; clean debris from racks and spray paths
Water on floor	Worn door seal	Inspect and replace the dishwasher door seal WPW10509257 if damaged
Burning smell	Item contacting heater, wiring issue	Stop the cycle, let it cool, inspect for contact or damage; follow safety guidance in the 66515789300 owner’s manual

Parts that commonly solve these problems

These are model-matched parts we often see tied to the symptoms above:

• Dishwasher door latch WP3380854 (door won’t close or unit won’t start)
• Dishwasher water inlet valve W10844024 (no fill or slow fill)
• Dishwasher float assembly WP3376397 (overfill protection float sticking)
• Dishwasher drain hose WP3374077 (leaks or drain issues)

Why it matters

Dishwashers rely on correct fill level, free-moving spray arms, and a tight door seal. When any of those basics are off, you can get long cycles, poor cleaning, or leaks, even if the control panel seems normal.

Kenmore is a brand name sold by Sears, and the Kenmore 66515789300 dishwasher is part of the Kenmore 665-series that was produced for Sears by a major dishwasher manufacturer. For model-specific identification details (model/serial format and service info), use the 66515789300 owner's manual.

How to identify the actual manufacturer for your exact unit

The most reliable way is to use the model and serial number tag on the dishwasher, then match that information to the service documentation.

• Open the door and look along the inner door frame or tub edge for the model/serial label
• Write down the full model number (66515789300) and the serial number
• Compare the label format to the service information in the manual
• Use the manufacturer prefix (often embedded in the model format) to confirm who built it
• Keep the numbers handy when ordering parts like a door latch, inlet valve, or heater

Why it matters

Kenmore dishwashers can share similar styling across different production runs, but parts compatibility depends on the exact model and serial information. Confirming the builder helps you avoid ordering the wrong spray arm, pump motor, or door seal.

On Kenmore model 66515789300 (Quiet Guard style), the filter is inside the dishwasher tub at the bottom, under the lower rack, around the sump area beneath the lower spray arm. For the exact removal and cleaning steps for your version, follow the 66515789300 owner's manual.

How to find it quickly

• Pull out the lower rack.
• Look at the very bottom center of the tub (the sump area).
• Identify the lower spray arm and the screen or filter basket beneath it.
• If a cover is present, it typically lifts out or twists off by hand.
• Rinse the filter screen under warm water and brush off debris.

What you may need to remove first

Depending on the exact configuration, you may need to remove the lower spray arm hardware to access the filter area.

Item you may handle	What it does	Related part (if replacement is needed)
Lower spray arm retaining nut	Holds the lower spray arm in place	Dishwasher spray arm nut WP8268873
Lower spray arm	Distributes wash water across the bottom rack	Spray arm WP8268874
Lower spray arm seal	Helps prevent leaks at the spray arm connection	Dishwasher lower spray arm seal WP3376846

Why it matters

A clogged filter can reduce wash pressure and leave food soil on dishes. Keeping the sump filter area clear also helps prevent drain issues and odors, especially if you run shorter cycles or frequently wash heavily soiled loads.

Tips to prevent repeat clogs

• Scrape large food scraps off dishes before loading.
• Run hot water at the sink for 30 to 60 seconds before starting a cycle.
• Use the correct detergent amount for your water hardness.
• Clean the filter area monthly (more often if you see debris).
