Rinse arms do not spin freely; dishes on upper racks remain dirty.

Safety first: Turn off power before removing rinse arms.

• Remove and clean arms: Detach upper and lower rinse arms. Rinse thoroughly and clear all jets and bearing holes.
• Descale bearings: Soak arms and bearing components in descaling solution to remove lime deposits.
• Check for damage: Replace arms that are cracked, warped, or excessively worn at the pivot.
• Verify rinse pressure: If arms still do not spin, check rinse pump and inlet pressure.
