What causes the Remeha E5 fault?
This fault occurs when the boiler's internal computer detects that the fan is not spinning fast enough to safely vent exhaust fumes outside. The most common reason is a mechanical failure within the fan motor itself or a blockage in the small air tubes that monitor pressure. Without a signal confirming that the air is moving safely, the boiler will shut down as a safety precaution.
