Master Gas Seoul Boiler Error Codes We will talk about how the malfunction of the boiler is coded by the manufacturer. Let’s show you what actions to be taken to correct the situation. From the article we presented, you will find out what kind of repair is needed to restore the unit and which of the shortcomings in the work can be eliminated with your own hands.

Master Gas Seoul Boiler Error Code A6
It indicates the absence of ignition. The flame ionization sensor, which controls the ignition, reports a malfunction. Such a part detects the presence of a flame and blocks the operation of the Master Gas Seoul boiler in case of incomplete combustion of the main burner or in case of gas supply problems. Work is suspended after 3 unsuccessful inclusions. To resume the workflow, keep the restart button pressed. Gas valve failure – The gas valve is electronically controlled.
Diagnostics of this element is carried out by determining the value of resistance and voltage. If the values are found to be out of specification, it is recommended to replace the valve. There is no gas supply to the boiler – A valve is installed in the gas distribution system, which can close the inflow of gaseous fuel. Based on this, a malfunction when turning on the unit may occur due to a closed valve. Weak contact or no signal from the flame ionization sensor.
Malfunction of the electronic control board – When the ignition process is carried out correctly, but the device immediately goes out anyway, then apparently the electronics cannot detect the flame. Based on this, it is recommended to test it. the electronics cannot detect the flame. Based on this, it is recommended to test it. the electronics cannot detect the flame. Based on this, it is recommended to test it.

Overheating of the boiler heat exchanger Master Gas Seoul. The unit stops. Overheating thermostat activated – The temperature sensor and the overheating thermostat are in most cases located on the outlet pipe of the primary heat exchanger. The functional task of the thermostat is to protect the boiler unit from excessive temperature increase. 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 – The electronic board receives an incorrect signal or the contact between the sensor and the electronic board is broken. Breakdown of the overheating thermostat – When the component is suitable for work, but a real overheating of the coolant is detected, then it is likely that there is a problem with the circulation of the coolant in the main circuit. The main heat exchanger or the heating circuit filter element is clogged (weak circulation gives an increased heating temperature of the liquid).
Master Gas Seoul Boiler Error Code A3
The circulation pump has failed or there is an air lock in the heating system.
Master Gas Seoul Boiler Error Code A5
Indicates low pressure inside the system. The main factors in which this problem occurs: a decrease in fluid pressure in the heating system. Contact failure between the pressure sensor and the electronic board. Pressure switch failure. The first step is to find out the pressure gauge values. Usually the failure can be eliminated with a make-up valve, which is installed to fill the system with coolant. In the event that a repeat of the emergency occurs, then most likely there is a water leak. The hydraulic pump, primary heat exchanger, excess pressure relief valve, worn seal elements, make-up valve and other components can leak. Leakage can be found by visual inspection of hydraulic connections and components.

Poor traction. For reliable and safe operation of the Master Gas Seoul gas boiler, it is necessary to create a draft for the removal of combustion products so that they do not enter the living quarters. The smoke output is monitored by electronics, and in the event of some problems, the draft sensor will work, and the gas appliance stops working. The main factors due to which there is no draft: the limited diameter of the chimney, a flaw in installation, clogging with dirt, icing of the inner wall.
The narrowing of the outlet channel causes insufficient traction. The length of the chimney pipe has been exceeded. We advise you to carefully study the operating manual for the boiler and comply with all necessary requirements. Too long a horizontal section of the flue pipe can cause a lack of necessary draft. Traction sensor failure – When a vacuum is created in the supply pipe, a soft click will be heard. There is no contact between the control board and the draft sensor, there is condensate, as well as an incorrect connection of the tubes with the pneumatic relay.
Damaged fan parts – There is a blockage in the fan impeller. There is no lubrication on the fan shaft, and therefore it has a low torque. Lost contact between fan and electronic board. in connection with which it has a low torque. Lost contact between fan and electronic board. in connection with which it has a low torque. Lost contact between fan and electronic board.

Problems with determining the temperature of the DHW sensor. This circumstance indicates that there is a malfunction of the temperature sensor in the DHW circuit or the operating temperature has been exceeded. Probable causes that influence the formation of this problem: the DHW temperature sensor is faulty. Disruption of contact between the control board and the DHW temperature sensor. The control board has failed. If the DHW temperature sensor is in good condition and firmly in contact with the control board, but the device displays an error, then it looks like the electronic control board is damaged.

Ignition is not performed. This code is issued if there is no ignition or there is an attenuation of the burner flame. It is required to inspect the connections between the ignition mechanism and the flame sensor, and in addition between the gas valve and the board. One of the factors of flame failure is the lack of thrust.

The temperature sensor in the heating circuit does not function correctly. This means that the temperature sensor of the heating system is damaged or that the desired temperature has increased significantly. The temperature sensor circuit in the heating circuit is damaged – This malfunction most often occurs when the contact of the temperature sensor with the control board is broken, or the temperature is lower than recommended. Five seconds after the detection of a malfunction, the Master Gas Seoul boiler will resume normal operation, in case the malfunction occurred spontaneously.
Make sure there is no moisture on the sensor connector and control board connector. If there is no moisture, the sensor needs to be replaced. There was a short circuit of the temperature sensor of the heating circuit – This failure can occur when the temperature sensor circuit is short-circuited or the temperature of the water is above normal. First, it is recommended to measure the resistance of the sensor. If the resistance values do not match the required values, it is recommended to replace the temperature sensor. When installing a working sensor does not contribute to the result, change the controller.
