Technical description: Boiler electr. system fault
What causes this fault?
This fault occurs when the boiler's internal computer brain loses touch with the sensors and controls it needs to operate safely. It is usually caused by a physical break in the internal wiring or a critical failure within the main circuit board's memory. Because the different parts of the boiler can no longer 'talk' to each other, the system shuts down as a safety precaution.
DIY fix possible
Press the 'Reset' button on the front display panel and hold for three seconds.Wait up to 10 minutes for the boiler to complete its restart sequence.Ensure your household electricity supply is stable and you have not recently had a power cut.
