5249DD2001A LG Upper Wash Arm Spinner

The Upper Wash Arm Spinner is a genuine replacement part designed for LG dishwashers, and it is also compatible with Sears-Kenmore models. Positioned at the upper rack level inside the dishwasher tub, this component features a series of jets that distribute water over the dishes on the top shelf during cleaning cycles. Over time, especially with frequent use, mineral deposits from hard water can clog the arm's internal channels.

Indications that the upper wash arm may need replacement include:

- Dishes on the upper rack not being cleaned properly
- Decreased water pressure from the top nozzles
- Visible mineral deposits in the spray arm's channels
- Ineffective water spray from the jets

These issues typically stem from a gradual accumulation of limescale or similar residues, which impede the flow of water through the arm's narrow passages. This part ensures effective water distribution and optimal dishwasher performance.
