GE Profile Dishwasher: Spray Arm Hitting Silverware... | appliancefaults.com

Technical Background:

The dishwasher's main control unit (MCU) governs the wash cycle, including spray arm activation. The motor receives 120V AC to rotate the spray arms. A thermistor monitors water temperature and relays this information back to the MCU. Any physical obstruction prevents the spray arm from moving correctly.

Symptoms:

The primary symptom is a repetitive knocking or scraping noise originating from the lower section of the GE Profile dishwasher during operation. Homeowners often describe it as the spray arm hitting the silverware basket.

Possible Causes:

Overloaded silverware basket causing expansion.
Silverware basket not properly positioned.
Warped or damaged spray arm.
Spray arm retaining clip is broken or missing.
Debris obstructing spray arm rotation.

Solution:

1

Turn OFF the dishwasher and disconnect power at the breaker panel. Verify the power is OFF using a non-contact voltage tester at the dishwasher outlet (receptacle).
2

Open the dishwasher door and carefully unload the dishes and silverware.
3

Inspect the silverware basket for damage or excessive loading. If overloaded, reduce the amount of silverware. Reposition if needed.
4

Examine the lower spray arm. Check for warping, cracks, or obstructions (food particles). Remove the spray arm by releasing the retaining clip.
5

Clean the spray arm thoroughly with warm soapy water. Check the spray arm nozzles for clogs. Use a small wire or toothpick to clear any blockages.
6

Inspect the spray arm retaining clip for damage. If broken, replace it. GE part number is usually located on the parts diagram.
7

Reinstall the spray arm, ensuring it's securely attached and rotates freely. Restore power at the breaker panel and test the dishwasher cycle.

Safety Warning:

Always disconnect power to the dishwasher at the breaker panel before performing any repairs. Verify the circuit is de-energized with a voltage tester. Use proper lock-out/tag-out (LOTO) procedures to prevent accidental re-energizing of the circuit.

Prevention:

Avoid overloading the silverware basket. Periodically inspect and clean the spray arms to prevent debris buildup. Ensure the silverware basket is always correctly positioned.

Expert Tip:

To quickly test the spray arm motor, access the dishwasher's service mode by pressing and holding the start button for 5 seconds. Select the 'Spray Arm Test' cycle to isolate motor performance from other components.
