The brew light flashes quickly and shuts off without brewing coffee

For some reason, people don't think too often about how dirty the ventilation system is, even though it is essentially the air they breathe indoors. I think it is very important to at least sometimes do Ventilation smoke test, and also contact experienced specialists who can quickly and efficiently clean the ventilation. Such services are also provided by Grease Gone.

You will know the machine wants to be descaled when the red alert triangle is blinking (lower right part of control pad)
1) Machine must be OFF and cool in order to descale the machine!
2) Fill the water container to MAX with very warm faucet water.
3) Add a packet of Illy / Urnex Dezcal or similar citric acid based descaler to the water, stirring it in until dissolved.
4) Replace the water container into your Illy Francis Francis X7.1 Iperespresso machine.
5) Place a 1L (minimum) plastic catch bowl (or other suitable container) under the brew head AND frothing wand, which should be pointed toward the center of the stage under the brew head (as in video above).
6) Power the machine ON.
7) IMMEDIATELY depress and hold only the BREW (coffee cup symbol) until the machine emits THREE SHORT BEEPS, followed by ONE LONG BEEP. Release the BREW button after the long beep.
8) Press the BREW button again, as you would when brewing a cup of espresso.
9) The machine will begin to PULSE, and the STEAM BUTTON will blink. The machine will alternate between pulsing water through the brew head opening and the frothing wand. This will continue until the water container is EMPTY. Be ready to remove the water container, and IMMEDIATELY refill it with cool (Brita filtered or distilled is best) water, and replace it as quickly as possible. The machine WILL NOT STOP THE DESCALING CYCLE, so replace the water container as quickly as you can. You will probably need to empty the catch bowl at least once or twice during this procedure, and the water will be VERY HOT, so use caution!
10) The machine will continue to pulse between the brew head opening and the frothing wand.
11) The machine will stop pulsing at some point during this second tankful, and the BREW button will begin to BLINK, with an alternating BEEP between blinking. If there is very little water left in the water container, fill it up with cool water again. Empty your catch bowl if it is full and you haven't already done so! Once everything is back in place, press the blinking / beeping BREW button, which will begin to rinse the machine through.
12) The machine may repeat Step 11 more than once!
13) The machine should now come out of DESCALING CYCLE on its own, with the red POWER button illuminated, along with the blue BREW button being on and solid.
14) Run one or two BREW cycles, with cool, filtered water.
15) Run the STEAM cycle for a few moments, as you would when frothing for a beverage, to ensure no descaler remains in the frothing wand.

Hi...Keep on grinding until the Auto Dosing System readjust the amount of grind to be in the optimum. Normally it takes 3 to 4 grinds. Whenever we change the type of beans, this condition happens, it is not a problem.

The thing that comes to mind is the brew unit is blocked and or the grind is too fine. Remove the brew unit and clean the screen under the red o-ring.

Open the brew mechanism. Opening the brew
mechanism will initiate the heating of the water and the
HEATING light will flash.
2 Place a clean cup on the cup stand, adjusting the height of the
stand up or down so that the rim of the cup is close to the
brew mechanism.
• To adjust the cup stand, insert your finger in the center
of the stand, lift and turn.
• To avoid spilling over, please choose the right sized cup for
the drink you are making.
3 Position your choice of T-DISC on the T-DISC holder, label facing
down. Firmly close the brew mechanism by pressing the clamp
down until it shuts. The HEATING light may flash again as the
machine heats the water to the required temperature for
your drink.
4 When the AUTO light illuminates, press and release the start/stop
button. Brewing will start automatically. There may be a short pause
during brewing; this is normal and is designed to draw out the full flavor
of your drink. The AUTO light flashes throughout the brew cycle. When
the machine has finished brewing, the indicator light will move from
AUTO to MANUAL and then, after a delay of 30 seconds, to HEATING.
5 Open the brew mechanism, remove the T-DISC and discard.
Your drink is now ready to be enjoyed.
You can prepare the next beverage right away by repeating
steps 2 - 5.

• All lights will blink the first time you turn on your
machine. This is your cue to prepare your machine for use by
following the quick instructions in Step 1 on separate insert.
• If the water level runs low while you are preparing a
beverage, all lights will flash. Simply remove and refill the
water container, and brewing will continue automatically
where it left off. It should not be necessary to discard the T-DISC
and start over.
• The AUTO light will blink throughout the brewing process.
Some drinks require a pause in brewing as part of the recipe
for brewing your perfect cup - this is to allow the optimal flavors
to unfold and is a normal part of the brewing process. The AUTO
light will continue to blink throughout this process.

HOW TO MAKE A DRINK
• Place the mug of your choice on the cup stand.
• When the STANDBY light illuminates, insert the T-DISC® of your choice
and close the clamp.
• The HEATING light will blink as the brewer heats the water to the
optimal temperature for your drink.
• Once the proper temperature is reached, the AUTO light will
illuminate. When it lights up, press the start/stop button to begin
the brew cycle.
• The AUTO light will continue to flash throughout the brewing cycle.
PLEASE NOTE: Some beverages have a pause in brewing
after the initial influx of water into the T-DISC®.
• The MANUAL light will illuminate when your drink is ready.

Sounds to me like you need to set the unit to the correct/actual time.

When you set the time for the machine to remain on after brewing you may have set it to zero. Am I in the ballpark?
