Machine will not start a cycle; all indicator LEDs flash red simultaneously when the power button is pressed.

Safety first: Unplug the Dolce Gusto machine from the mains before any inspection. Never open the housing while connected to power.

Step-by-step checks:

• Power reset: Unplug the machine for at least 10 minutes to allow the control board to discharge. Plug back in and try again.
• Check outlet and adapter: Test the wall outlet with another appliance. Avoid using loose multi-plugs or extension cords; plug the machine directly into a grounded outlet.
• Inspect for overheating: If the machine was used repeatedly, let it cool for 30–40 minutes. Overheating can trigger protection and cause flashing LEDs.
• Check for internal short signs: With the machine unplugged, look through ventilation slots for signs of burnt smell or melted plastic. If present, do not power it again.
• Try a different location: Voltage fluctuations can trigger protection. Test the machine on a different circuit in the house.

When to stop: If all LEDs continue flashing red after a full power reset and cooling period, the fault is likely on the control board, heater, or pump circuit. Do not attempt to open the housing unless you are trained; contact an authorized Dolce Gusto service center.
