Robot vacuum reports C12; dustbin not detected or dustbin error.

Safety: Turn off the robot before removing the dustbin.

• Reinsert dustbin: Remove the dustbin completely and then firmly push it back into place until it clicks.
• Clean detection area: Inspect the area where the dustbin slides in. Look for a small mechanical switch or optical sensor. Clean it gently with a dry cloth or compressed air.
• Check dustbin tabs: Examine the plastic tabs or protrusions on the dustbin that trigger the sensor. If a tab is broken or worn, the sensor may not detect the bin.
• Test with another dustbin: If available, try a different compatible Dreame dustbin to see if the error clears.
• Internal check: If the sensor still does not detect the bin, inspect the dustbin sensor circuit on the main board for loose connectors or damage.
• Replacement: Replace the dustbin assembly if its tabs are broken, or the main control board if the sensor circuit has failed.
