Monogram dishwasher makes loud banging or knocking noise during fill or wash.

Safety: Turn off power and water before adjusting plumbing or mounts.

• Check mounting: Ensure the dishwasher is securely fastened to the cabinet with mounting brackets.
• Inspect loading: Remove tall items that may interfere with spray arm rotation.
• Secure hoses: Access the base and secure any loose hoses or components that may bang against the frame.
• Address water hammer: If banging occurs when the inlet valve closes, consider installing a water hammer arrestor on the supply line.

After adjustments, run a test cycle to confirm noise reduction.
