What causes the Warmhaus rE88 fault?
This fault occurs when the boiler's internal computer detects an inconsistency or failure in the electrical communication with the gas valve. The most common reason is that the valve can no longer open or close accurately to regulate fuel flow, or the main circuit board is unable to send the correct signals to it. To prevent an unsafe combustion situation, the system automatically shuts itself down.
