A machine for preparing coffee or the like. The machine includes a pump supplying water; a unit for preparing and dispensing of coffee, with a dispensing seating, and an upstream electric heater for heating the water passing through the heater; a hydraulic circuit which connects the pump to the inlet of the heater and which includes solenoid valves assuming a rest configuration in which the heater is substantially emptied of water, and a working configuration in which the heater is enabled to receive and be traversed by a flow of water sent by the pumping devices for the preparation of the coffee; and a control unit (ECU) arranged for activating the heater and causing the solenoid valves to change to the working configuration only when a command is issued for the preparation and dispensing of coffee. |
