What Does the Bosch Error Code E4 Mean?
With your water temperature controller, you can conveniently self-diagnose any faults that occur within the unit. If a fault is detected the digital monitor of the controller will flash an error code. This error code pinpoints exactly what is wrong within the appliance, allowing for a fast repair. One of the Bosch hot water error codes that may be displayed is error code E4.
If the Bosch fault code E4 is flashing on the status monitor of your controller this indicates your backflow temperature sensor is over 309° F.
