Our recommendations will help you choose the right way to restore boiler performance. You will be able to decide: it is worth correcting the situation yourself or it is better to call the gas men.
Hubert Boiler Error Code Solutions
Hubert Boiler Error Code E2
It indicates that the ignition is blocked. The ionization flame sensor indicates a malfunction of the device. Such a sensor-electrode detects the presence of a flame and blocks the operating cycle of the Hubert gas boiler during insufficient combustion of the main burner device or in cases of gas failure. Blocking occurs after three unsuccessful launches. To get it working, you need to keep the reset button pressed. Gas valve failure – The operation of the gas valve is controlled by an electronic board.
Diagnostics of this element is carried out by determining the values of resistance and voltage. If it turns out that the readings do not correspond to the nominal characteristics, it is necessary to replace the valve with a new one. No gas flow to the unit – There is a valve in the gas distribution device, which limits the flow of gas. Based on this, a failure to start the unit may occur due to a closed valve. Insufficient contact or no signal from the ionization flame sensor. The control board has a malfunction – If the ignition cycle is normal, but the device still suddenly goes out, then apparently the electronics do not detect a flame. In this case, it is recommended to diagnose it.
Hubert Boiler Error Code E7
Hubert boiler heat exchanger overheating problem. The device is blocked. Overheating thermostat activated – The temperature sensor and overheating thermostat are usually located on the outlet pipe of the main heat exchanger. The main task of the thermostat is to protect the instrument from excessive temperature rise. A malfunction may occur due to problems in the thermostat, temperature sensor, as well as in the event of a malfunction in the main circulation circuit.
Damaged temperature sensor – An incorrect signal is received on the control board or a contact is broken between the sensor and the control board. Failure of the overheating thermostat – If the component is suitable for work, although the actual overheating of the coolant is detected, then, apparently, there was a problem with the circulation of the coolant in the heating circuit. Blockage of the primary heat exchanger or filter element of the heating circuit (low circulation level causes increased heating of the liquid). Malfunction of the circulation pump or an air blockage has formed in the heating system.
Hubert Boiler Error Code E1
Indicates low pressure inside the system. Probable causes influencing the formation of this malfunction: low coolant pressure in the heating circuit. The contact between the control board and the pressure sensor is broken. Malfunction of the minimum pressure switch. First you need to find out the readings of the manometer. Usually the problem can be fixed with a make-up valve that is installed to fill the system with coolant. When the accident repeats again, then most likely there is a coolant leak. The hydraulic pump, main heat exchanger, excess pressure relief valve, damaged gaskets, make-up valve and other parts can leak. A leak can be identified during an external inspection of hydraulic components and connections.
Hubert Boiler Error Code E6
Insufficient traction. For the correct and safe operation of the Hubert boiler, it is necessary to provide draft for the removal of combustion products so that they do not enter the living quarters. The exhaust of gases is controlled by electronics, and in case of certain problems, the draft sensor will work and the device will stop working. Probable causes affecting the lack of draft: limited diameter of the chimney channel, installation defect, clogging, ice on the walls. Reducing the diameter of the flue duct causes insufficient draft. Exceeding the maximum length of the chimney It is recommended that you carefully read the instructions for use of the gas appliance and check that the mandatory requirements are met.
A very long horizontal outlet of the chimney pipe can cause a lack of necessary draft. Draft sensor damage – If a vacuum occurs in the inlet tube, a soft click will be heard. There is no contact of the control board with the pneumatic relay-traction sensor, the presence of condensate, as well as incorrect fastening of the tubes with the pneumatic relay sensor. Fan malfunction – There is a blockage in the fan impeller. The lack of sufficient lubrication of the fan shaft, respectively, it does not develop the necessary speed. Poor contact between control board and fan. The lack of sufficient lubrication of the fan shaft, respectively, it does not develop the necessary speed. Poor contact between control board and fan. The lack of sufficient lubrication of the fan shaft, respectively, it does not develop the necessary speed. Poor contact between control board and fan.
Hubert Boiler Error Code E4
The hot water temperature sensor is not working correctly. This situation indicates a malfunction of the temperature sensor in the hot water circuit or the temperature required for operation is too high. Probable sources of this problem: the hot water temperature sensor is damaged. The contact between the DHW temperature sensor and the control board is broken. Failure of the electronic board. If the hot water temperature sensor is working and is firmly connected to the control board, but at this moment the device gives an error, then it looks like the electronic control board needs to be replaced.
Hubert Boiler Error Code E5
Incorrect ignition. This situation occurs if the ignition mechanism does not work or flame separation is observed. It is necessary to inspect the contacts between the ignition unit and the flame electrode, and also between the gas valve and the board. One of the factors for the attenuation of the flame of the burner may be weak draft.
Hubert Boiler Error Code E3
The heating circuit temperature sensor is not functioning properly. This circumstance indicates that the heating circuit temperature sensor is damaged or the permissible temperature has risen. Damage to the heating circuit temperature sensor circuit – This malfunction most often occurs if the connection between the temperature sensor and the electronic board is interrupted, or the temperature is lower than recommended. After five seconds have elapsed following the detection of a fault, the Hubert boiler must resume operating functions, in case the fault occurred spontaneously.
It is necessary to check that there is no moisture on the sensor connector and the controller connector. If there is no moisture, the sensor needs to be replaced. There is a short circuit in the heating water temperature sensor – This problem occurs during a short circuit in the temperature sensor circuit or the temperature value of the coolant is above normal. First you need to measure the resistance of the temperature sensor. If the resistance indicators differ from the nominal ones, you need to change the sensor. If installing a working sensor does not work, change the electronic board.
