Machine shows E07 and may not dispense coffee; internal clicking or motor noises may be heard without water flow.

Safety first: Unplug the machine and let it cool before any inspection.

User-level checks:

• Run descaling cycle: Scale can block the diverter valve. Perform a full descaling cycle, ensuring you follow the prompts for hot water and coffee outlets.
• Operate all functions: After descaling, run hot water, steam, and coffee cycles to exercise the valve and clear minor blockages.
• Listen for valve click: During operation, you should hear a distinct click when the valve changes position. Absence of this sound may indicate a failed solenoid.

When to call a technician: If E07 persists or water only exits from one outlet regardless of selection, the diverter valve or its coil likely needs replacement by a service professional.
