What causes the Vokera E10 fault?
This fault occurs when the boiler's internal safety circuit is broken, usually because the system has lost too much water pressure to operate safely. It can also be triggered if the unit begins to overheat, causing a safety sensor to trip and shut down the burner to prevent damage. The most common reasons are a leak somewhere in the central heating system or a faulty sensor that is incorrectly reporting a problem.
