Are you using gas heating equipment? Then you know that even reliable units can fail. If the Hephaestus boiler displays an error code, it means that a system error has occurred. Protective automation sends a signal to the control module, which issues a code on the display. Each character set indicates a specific problem. Which one? We described in detail in the table.
Features of operation of a gas boiler Gefest
The equipment is presented in two series: Star and Econom. Power ranges from 16 kW to 32 kW. These are dual-circuit models. The heating heat exchanger is made of copper in the form of a curved tube. The secondary radiator for hot water (DHW) is also copper. But its design consists of several plates.
A steel burner is ignited by a piezoelectric element. A closed combustion chamber includes a fan. He forcibly removes carbon monoxide. A coaxial chimney is connected to the camera. It consists of two pipes, one of which emits smoke, and the other receives air to maintain the flame. The chimney is discharged into a hole in the wall.
The circulation pump has three adjustable speeds. Includes air vent. Therefore, air jams in the system are extremely rare.
A 6 liter diaphragm tank is part of the design. It takes in excess fluid when heated. Safety automation protects the user from emergency situations.
Errors and malfunctions
Once the self-diagnosis system displays an error code, eliminate the system malfunction. To do this, restart the boiler. After reconnecting, check whether the icons are displayed again or not. If so, then take a look at the instructions or study our table.
Malfunction code | What does it mean | How to fix it yourself |
Error E1 | The water pressure in the circuit has dropped. |
|
Error E2 | Problems with ignition and flame maintenance. | What to do:
Replace the broken parts with new elements. |
Error E6 | Problems with the removal of combustion products. | How to proceed:
|
E7 | Overheat protection tripped (thermal fluid temperature sensor). | First of all, check the temperature sensors and their connections. If overheating really happened, check:
|
HER | The user entered erroneous numbers. | Recheck the indicated values. |
Other malfunctions
If you occasionally use the boiler, after a long period of inactivity the pump may not start. In this case, remove its plug and turn the shaft counterclockwise. Repeat the start of the boiler.
To avoid scale buildup in the heat exchanger, it is recommended:
- Install magnetic filters to soften water.
- Do not use a heating temperature above 55 degrees, since it is then that scum begins to be actively deposited.
Monitor the operation of heating equipment, conduct timely technical inspections.
