C3452: Pressure Heater Trouble.
Try to reset it like this:
Shut down from the main power switch (the one behind the front cover).
Keep pressed the Utility/Counter button.
Power on while the button is kept pushed.
Release the 'Utility/Counter' button only when you see the 'Trouble Reset' button on the touch screen.
Touch the 'Trouble Reset' button, a small ok should pop up underneath.
Power off, wait for a few seconds and then power on.
