Saeco manufactures a line of high-end coffee and espresso machines for home and commercial use. The coffee machines have a built-in LED panel to display various status messages and to alert the owner to perform necessary maintenance. Part of the regular maintenance of a Saeco machine is ventilation, which cleans out the boiler unit and removes coffee residue. The process involves running boiling water through the unit.
Turn on the Saeco coffee machine by pressing the "On/Off" button on the front control panel. If the LED display on the front of the Saeco shows the message "Ventilate" you'll need to perform this routine maintenance.
Place a cup under the "Steam/Hot Water" nozzle on the front of the Saeco.
Pour hot water into the reservoir on top of the Saeco and pull the lever over the Steam/Hot Water nozzle to run the water through the boiler into the cup.
Release the lever and empty the cup when it is full. Continue running hot water through the machine into a cup until the "Ventilate" messages disappears on the LED screen.
