What to do if my LAVAZZA Blue LB 2000 Coffee Maker does not detect water flow?

If your LAVAZZA Coffee Maker isn't detecting water flow, several issues could be the cause. It could be due to a broken CPU card, a short circuit or broken temperature sensor, a hydraulic circuit tube that is interrupted, clogged, or disconnected, an occluded unit, a solenoid valve that is occluded or broken, a damaged or interrupted pump, a pump thermal switch that is off, a heating unit occlusion, a broken power card (TRIAC), a non-functioning command from the CPU card, or a completely discharged CPU card battery. You should check the coffee temperature sensor, the hydraulic circuit, the unit, the solenoid valve, the pump and its thermal switch, the heating unit, the power card, and the CPU card.
