MODEL-SPECIFIC QUICK ANSWER

Profitec PRO 400 blinking lights and common signals

On the PRO 400, a green LED flashing two seconds on and one second off means the water tank is low or not inserted. Refill and reseat it. Let the machine warm up before judging the boiler gauge; use grind and dose checks for extraction pressure, and do not adjust the expansion valve or open the boiler.
