To avoid this problem the walls of the boiler and the heating elements need to be regularly cleaned.

Next, remove the flange from the tank. The flange is equipped with Tan and the anode rod (or its remnants). It should be cleaned from scale and PETN layers and implement a replacement rod.
After cleaning the boiler going, and then, after starting the cold water, checked the tightness of all connections. Further, the device is connected and checked his work.
