The top rack adjuster assembly (part WPW10546503) on several models of KitchenAid, Whirlpool, and Kenmore dishwashers is highly loaded and very underbuilt. I designed these snap-fit adjusters to replace the factory parts. They are non-adjustable, but much stronger than the factory design.
Based on this Amazon listing, this design is probably compatible with the following dishwasher model numbers:
4KAER7685EW0, 4KMER7600AW0, 4KMER7685ES0, 4KMER7685EW0, 4KWFC120MAW0, 4KWFE7685ES0, 4KWFE7685EW0, ACR4303MEB0, ACR4303MES0, ACR4303MEW0, ACR4503SEB0, ACR4503SES0, ACR4530BAB0, ACR4530BAW0, AER5330BAB0, AER5330BAS0, AER5330BAW0, AER5630BAB0, AER5630BAS0Selecting parts
Two adjuster sizes are available: high and low. They correspond to the height setting of the top rack. The height setting of the top rack can be changed by replacing all 4 adjusters with the other size. I prefer the high setting.
You'll need to print the following parts:
- 2x left side adjusters
- 2x right side adjusters
- 4x retaining clips
No additional hardware is necessary.
Installation
To install the parts in the dishwasher:
- Remove the top rack from the dishwasher.
- Remove the factory adjuster assembly. Note the location of the pins on the adjuster relative to the wire grid.
- Snap each new adjuster into the correct space on the wire rack, then slide it up until the top clip snaps onto the horizontal wire.
- The ear on each adjuster's support pin should point out, away from the center of the rack.
- Each side of the rack will need 1 left side adjuster and 1 right side adjuster.
- Snap a retaining clip to the lower end of each pair of vertical wires holding an adjuster. The retaining clip prevents the wires from spreading out and releasing the adjuster.
Selecting Filament
Dishwasher parts require heat, water, and chemical resistance. Good strength up to at least 80°C is essential. Some types of ABS or ASA might work. I used Siraya PET-CF15 and annealed the parts.
