Wash arms do not rotate; dishes in some areas remain dirty.

Safety first: Switch off power and let the machine cool before handling wash arms.

• Clean wash arms: Remove wash arms and clear all jets of debris and scale. Rinse thoroughly.
• Check for obstructions: Ensure tall items or incorrectly loaded racks are not blocking arm rotation.
• Inspect bearings: Replace worn or seized bearings or bushings in the wash arm hubs.
• Verify pump output: If arms still do not rotate, check wash pump performance and impeller condition. Replace the pump if pressure is inadequate.
