What causes the Warmhaus E92 fault?
This fault occurs when the boiler's internal sensors detect that high winds or air pressure fluctuations are interfering with the correct mix of gas and oxygen. It usually means the boiler is struggling to maintain a stable flame because the flue is being buffeted by external air or there is a minor leak in the internal seals. The system triggers this protection mode to prevent the boiler from burning gas inefficiently or unsafely.
This fault is significantly more frequent during autumn and winter, as it is typically triggered by the high winds and stormy weather common during these months.
