Monogram dishwasher leaves gritty residue or sand-like particles on dishes.

Safety: Disconnect power before reaching into sump; beware of sharp glass.

• Remove and inspect filters: Clean thoroughly and replace if damaged.
• Clean sump: Remove all visible debris, including glass and hard particles.
• Check drain connection: Ensure the drain hose has a high loop or air gap to prevent backflow from sink/disposer.

After cleaning, run an empty cycle to flush remaining particles.
