Technical description: Gas valve switch-off control fault
What causes this fault?
This fault occurs when the boiler's control board detects that the gas valve is not shutting off correctly or is drawing the wrong amount of electrical current. The most common reason is an internal electronic failure within the valve itself or a communication error from the main circuit board failing to regulate the gas flow safely.
Engineer required
