What causes the Worcester Bosch 2924 V fault?

This fault occurs when the boiler's main computer loses touch with the gas valve that controls the fuel flow. It is usually caused by a physical failure of the electronic relay on the control board or a malfunction within the gas valve's internal motor. Because the boiler can no longer verify if the gas is being turned on or off safely, it shuts down as a protective measure.

Typical repair cost £250-£450 (including labour)
