WP8558129 is a genuine Whirlpool-manufactured dishwasher detergent dispenser assembly used when the original part is worn, damaged, missing, leaking, noisy, or no longer performing correctly.

This part commonly replaces previous part numbers including 8558129, 8558128, 9744543, 9744542, 8270034, 8270032, 8269121, 8269996.

Fitment / What To Verify: Verify the full dishwasher model number, dispenser color, door cutout shape, latch style, rinse-aid indicator design, and wire-harness situation. If the old dispenser used a two-wire rinse-aid sensor, the replacement design may require securing that unused harness out of the way.

Please confirm fitment with your appliance model number before ordering.

Is it time to replace?

• Common Symptoms: Detergent cup will not open, soap remains in dispenser, rinse aid leaks, dispenser door broken, or dishes are not cleaning due to detergent not releasing.
• Visible/Sensory Cues: Cracked dispenser body, broken latch, leaking rinse-aid reservoir, sticky door, or corrosion around dispenser terminals.

Pro Tip: Clean the door surface under the old dispenser before installing the new one so the gasket seals evenly.
