Page 29: Magnesium Anodes 18. (Fig.14)
10.4. Magnesium anodes 18. (Fig.14) The magnesium anode (Mg), also called "sacrificial" anode, avoids any parasitic currents that are generated inside the boiler that can trigger corrosion processes on the device surface. In fact, magnesium is a metal with a lower electrochemical potential when compared to the material that lines the inside of the boiler, therefore it first attracts the negative charges that form with the heating of the water and that cause it to corrode. - Page 30 1) The sensor open circuit 1) Check the sensor Upper tank ☆☆● connection 2) The sensor water temp. short circuit 2) Replace the sensor (2 flashes 1 dark) sensor failure 3) PCB board 3) change the PCB board failure 1) The sensor open circuit 1) Check the sensor 2) The sensor...
