Display shows 'dU' and the vacuum will not start after emptying the bin.

Safety first: Remove the battery pack before adjusting the dust bin.

• Reinstall dust bin: Remove the bin completely and reinstall it, ensuring it slides into place and clicks firmly.
• Check for obstructions: Inspect the bin rails and latch area for debris preventing full engagement. Clean with a dry cloth.
• Inspect bin switch: Look for a small plastic tab on the bin that actuates a switch on the body. If the tab is broken, the bin may not be detected.
• Replace bin or switch: If the bin cannot latch securely or the detection switch is physically damaged, replace the dust bin assembly or the bin detection switch as appropriate.
