Machine displays repeated prompts to empty coffee grounds (dreg drawer) even when it is empty and reinserted.

Safety first: Turn off and unplug the machine before inspecting the dreg drawer area.

Step-by-step checks:

• Clean drawer and compartment: Remove the dreg drawer and clean it thoroughly. Wipe the compartment to remove coffee residues that may block the switch.
• Inspect tabs: Check for broken or worn plastic tabs on the drawer that actuate the internal switch.
• Reinsert firmly: Push the drawer fully in until it stops; partial insertion may not trigger detection.

When to call a technician: If the message persists, the microswitch or sensor may be faulty and should be replaced by a professional.
