What to do if my Catler ES 721 PORTO B's indicator light flashes red?

If the indicator light on your Catler Coffee Maker is flashing red, it could be due to several reasons: the tank might be empty, so refill it. There might be no water in the machine, in this case, pull out the capsule holder for the ground coffee. It could also happen after a factory reset, so insert the holder back into the coffee machine.
