During the use of the electric boiler, the pressure suddenly drops, and the instrument indication is abnormal. What should I do?

The air in the duct is not exhausted. Under normal circumstances, the internal pressure of the electric boiler system is constant. Once the pressure of the electric boiler system suddenly decreases, the instrument indication is abnormal, which can easily lead to damage or failure of the electric boiler system.

Treatment: Open the exhaust valve to discharge the gas in the pipe, and close the other parts of the system at the same time. Then check the piping and other components.
