Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Upper dishrack is loose, sagging, or poorly supported on the left side.
• Upper dishrack height adjustment does not hold or operates incorrectly.
• Rack alignment is uneven, which may interfere with door closing.
• Visible cracking or breakage at the left adjuster housing or its retaining tabs.

Check Before Replacing

• With the dishwasher empty and the upper rack pulled out, visually inspect the left adjuster housing for cracks, broken tabs, or separation.
• Gently move the upper rack side-to-side and compare left-side stability with the right side; excessive looseness can indicate a damaged housing or related adjuster component.
• Operate the upper-rack height adjustment gently and confirm that the left-side housing remains attached and aligned.
• Check that the housing is installed on the left side and that the related adjuster, cover, and wheel assembly are seated correctly before condemning the housing.
