Abstract
A control system for delivering filtered liquid to a reservoir of a beverage machine. The liquid level within the reservoir is monitored, and when the liquid level is at or below a predetermined level, a valve opens to allow liquid to flow to the reservoir. Once the liquid level has reached or obtained a predetermined liquid fill level, the valve is closed.
