Technical description: Gas valve current fault, try resetting the boiler
What causes this fault?
This fault occurs when the boiler's main computer loses the ability to correctly control the electrical signal sent to the gas valve. The most common reason is a physical failure of the internal solenoids within the gas valve or a communication break in the wiring connecting it to the control board. For safety reasons, the boiler immediately stops ignition because it can no longer guarantee the precise regulation of gas flow.
