Technical description: Combined ignition control
What causes this fault?
This fault occurs when the boiler's main control board loses the ability to communicate with the components that spark the flame. It is usually caused by a physical failure within the circuitry or damaged internal wiring that prevents the system from safely initiating the ignition process. In some cases, old or worn-out ignition electrodes can create an electrical feedback that triggers this specific computer error.
