Machine powers on but will not start brewing; pressing coffee buttons has no effect or only triggers a brief noise.

Safety first: Keep hands clear of moving parts when the machine is powered.

Step-by-step checks:

• Check on-screen messages: Look for prompts such as “Insert brew group”, “Close door”, or “Empty coffee grounds” and follow them.
• Reinsert components: Remove and firmly reinsert the water tank, drip tray, dreg drawer, and brew group. Ensure each clicks into place.
• Close doors fully: Make sure the service door and front panel are fully closed and latched.
• Power reset: Turn the machine off, wait 30 seconds, then turn it back on and try again.

When to call a technician: If the machine still refuses to brew with all components correctly installed, a door or presence switch may be faulty and should be tested by a technician.
