Machine frequently asks to empty the drip tray even when it is nearly empty.

Safety first: Unplug before reaching into the tray area.

• Clean tray and float: Remove the drip tray, wash it thoroughly, and ensure the internal float moves freely.
• Clean sensor area: Wipe the sensor window or switch area inside the machine to remove coffee residue.
• Reinsert tray fully: Push the tray in until it is flush with the front panel.
• If problem persists: The tray sensor or microswitch may be faulty and require replacement.
