What does the double flashing of the steam light mean on my COM530 and COM532 combination unit?
The double flashing of the steam light means the espresso side of the unit require to be descale. To descale it please follow the steps:
1) Fill the tank with 100ml (3.3 oz) of descaler and the rest with water. 2) Press the “Espresso ON/OFF” button to turn the machine on. The integrated light flashes. 3) Make sure the portafilter is not attached and place a bowl under the boiler outlet. 4) Press and hold the steam button for at least 6 sec. This will start the automated Descaling Process. 5) While the machine starts dispensing water, open once steam knob 2-3 seconds to discharge a little water from the frother system. The clock will switch to a countdown (27 min) during the process and will revert back after the end of descaling.The steam button (B3) will blink until the end of descaling. 6) To eliminate residues of solution and scale, rinse the tank well, then fill it again with fresh water (without descaler). 7) Press the button and deliver water until the tank is completely empty.While the machine starts dispensing water, open once steam knob 2-3 seconds to discharge a little water from the frothing system. 8) Repeat operations 6 and 7 again.
