I need to prime the water circuit. How do I do this?

When prime water circuit comes on turn on the steam/water valve may need to select hot water the machine will run water until primed

The turbine flow meters contacts are corroded, or the turbine itself is broken.

You need to draw hot water from the machine in order to prime the machine after the masage leave you can us the machine normaly. If the masage apears very often then you will need to descale the machine.

Fill the water tract with the water. For example - swith the steamer to hot water dispence and run water for several seconds (untill it goes smoothly).

Circuit Priming
When the machine operates for the first time and when
all the water has been dispensed, the machine circuit
needs priming. In this case, the 4 buttons of the control
panel will flash at the same time.
• Press the ON/OFF button . The 4 buttons will
flash.
• Place a container under the cappuccinatore.
• Open the "hot water/steam" knob by turning
it anticlockwise.
• Press the hot water button.
• Wait for water dispensing to stop.
• Close the "hot water/steam" knob by turning it
clockwise. Remove the container.
When the first priming ends, the warming up
starts. Before brewing coffee, water and steam,
please wait for lights 15 and 16 to be permanently on.
The machine is now ready to brew coffee and dispense
steam. Please see related sections for operating details.
Note: if priming is not completed, the 4 buttons
will keep on fl ashing. The machine cannot be
used.

Having read the other reviews here, I was prepared for the cryptic "VENTILATE" message. (The manual refers to this procedure as "Loading the circuit", which doesn't help to clarify things.) Of course this refers to what Americans would call "priming" the machine. As mentioned in another review, there is a plastic hand pump supplied for priming, but that is only needed in the event that the electric pump fails to self-prime. All I had to do (following the quick-start instructions) was to select the Hot Water function; the internal pump quickly primed itself. i hope this helps Lee Davidian

Prime refers to priming the pump. The error message means that there is air in the system which is preventing the pump from pumping water. To correct this, fill the tank with water, press the water button on the right side, and turn the water/steam knob to open. Allow the water to flow until the stream is steady. Press the water button again and your problem should be fixed

Hi You need to switch Steam ON so it heats up and then turn Steam button OFF (no light) and then turn steamer knob counter clockwise you will hear the pump start up and then water will stream out. This is when it's primed. Turn steamer clock wise to close. You must do this everytime you use the steamer.

This is a common problem that is not explained in the manual. Turn the left silver knob on the top deck of the machine past the steam icon to the water drop icon. Let about eight ounces of water out into a cup and the circuit is primed.
