✅ Cross Reference Information

Common Symptoms

• Upper rack is difficult to raise or lower.
• Rack will not stay at the selected height.
• Rack slides unevenly or does not move properly.
• Rack drops or falls on one side.
• Visible cracks, broken tabs, or other damage to the adjuster.

Check Before Replacing

• With the dishwasher empty and the door open, gently move the upper rack through its height-adjustment positions; do not force it.
• Visually inspect the adjuster on both sides for cracks, broken retaining tabs, separation, or missing pieces.
• Check that the rack remains engaged with both tracks and that neither track is visibly bent, separated, or obstructed.
• Compare the suspect adjuster with the intact opposite-side adjuster for missing or misaligned parts.
• Confirm the appliance model before ordering, because track and adjuster components can vary by model.
