Kenmore 66517722K900 dishwasher Parts

When the Start button won’t respond on your Kenmore dishwasher model 66517722K900, the most common cause is the door not closing and latching tightly, which prevents the dishwasher from running even if other lights work. Use the checks in the 66517722K900 owner's manual to confirm the correct start procedure and basic power checks.

• Press the door closed firmly and confirm it latches completely.
• Verify the cycle is actually selected (some models use a cycle control knob and won’t run if it’s set to Off).
• Check the home breaker or fuse; reset if tripped.
• Make sure the dishwasher has power (other symptoms can be misleading if the control is partially powered).
• If the motor is overloaded, wait a few minutes; many units reset automatically.

A dishwasher that won’t start often acts like the Start button is bad, but the control is really waiting for a closed-door signal.

• Inspect the latch for looseness, misalignment, or a weak catch.
• If the latch feels sloppy or won’t hold the door shut, replace the dishwasher door latch WP3380854.
• Check the strike area and mounting screws; a shifted door panel can keep the latch from engaging.

The door latch is a safety interlock. If it is not fully engaged, the dishwasher protects you by preventing the wash motor and heater from running.

After confirming the door latches, a simple power reset can clear a stuck control state: turn off power at the breaker for about 5 minutes, then restore power and try starting a normal cycle.

Common problems on the Kenmore 66517722K900 dishwasher include not starting, not filling, poor cleaning, leaking, and spotting or filming. Many issues trace back to a door that is not fully latched, a tripped breaker, a stuck overfill float, or maintenance items such as detergent and interior cleaning (see the 66517722K900 owner's manual).

• Confirm the door closes tightly and latches (a loose latch can stop the cycle).
• Check the house breaker or fuse and restore power if needed.
• Verify the water shutoff valve is turned on.
• Listen for normal pauses during the wash cycle (some cycles pause briefly).
• Inspect for obvious leaks around the door perimeter.

Hard water and detergent buildup can cause white film inside the tub and on dishes. For this Kenmore dishwasher, we recommend cleaning the interior with dishwasher detergent (not household cleaners), then running a normal cycle with detergent afterward. For spotting and filming, a vinegar rinse can help.

Vinegar rinse (film and odor control):

• Remove silverware and metal items.
• Place 2 cups of white vinegar in a dishwasher-safe cup on the bottom rack.
• Run a complete cycle using an air-dry option (no detergent).

Dishwashers often “act broken” when a safety condition is triggered (door not latched, float stuck) or when maintenance is overdue (mineral film, detergent residue). Fixing those basics first prevents unnecessary part replacement and helps restore normal wash and dry performance.

To reset a Kenmore Ultra Wash Quiet Guard dishwasher like model 66517722K900, we cancel the current cycle and restart it. On many Quiet Guard models, turning the cycle control to Off (or using Reset) clears the selection so the dishwasher can begin a fresh fill and wash.

• Lift the door latch to pause the cycle.
• Turn the cycle control knob slowly clockwise until you hear the dishwasher start draining.
• Let it drain completely.
• Open the door, then turn the cycle control knob to Off.
• Close the door firmly, then select a new cycle and start.

For the exact control layout and button names on your unit, follow the steps in the 66517722K900 owner's manual.

Some versions let you press RESET to turn an option off or clear a selection before that option begins.

• Press RESET once to clear the option or selection.
• Re-select the cycle and options you want.
• Close the door firmly until it latches so the cycle can restart.

If the dishwasher does not run after a reset, we focus on the basics from the troubleshooting section:

• Door is closed tightly and fully latched.
• House circuit breaker is on (or fuse is good).
• Water shutoff valve is turned on.
• Overfill protection float moves freely; press down to release.
• Motor overload: wait a few minutes for the motor to reset itself.

A proper reset clears a stuck cycle and forces a clean restart (drain, fill, wash). That prevents standing water, detergent dumping at the wrong time, and repeated mid-cycle stops.

On the Kenmore 66517722K900 Quiet Guard-style dishwasher, the filter is in the bottom of the tub, under the lower dishrack, around the sump area near the spray arm and spray tower. Access it by pulling out the lower rack and lifting the filter basket straight up. See the 66517722K900 owner's manual for the exact removal and reinstallation steps for your version.

• Turn off power at the breaker before reaching into the tub
• Pull the lower rack fully out (or lift it off the rails)
• Look at the tub floor near the center where wash water collects (sump area)
• Locate the filter basket or screen assembly around the spray arm base
• Lift the filter basket straight up; it typically seats in place rather than clipping in

A clogged filter area can cause poor cleaning, gritty residue, or drainage issues.

• Remove food debris and rinse the filter basket under warm water
• Check the spray arm openings for clogs
• Make sure the overfill protection float at the front right moves freely
• Inspect the tub floor for broken glass or labels that can block flow
• Confirm the filter is fully seated flat when you reinstall it

The filter area protects the wash pump and keeps soil from recirculating onto dishes. Keeping it clean helps your Kenmore 66517722K900 wash better, drain more reliably, and run quieter.
