• a liquid injection arrangement comprising a pump for pressurising and circulating liquid from a source via the cartridge seat into the beverage outlet, the liquid injection arrangement comprising a valve between the pump and the cartridge seat;
• and
• the liquid injection arrangement is configured to selectively release via the valve pressure from the pressurised liquid in the injection arrangement and maintain liquid in the injection arrangement from the pump to the cartridge seat after the pump is stopped, so as to inhibit dripping from the beverage outlet, the ingredient cartridge being held in the cartridge seat of the device.
