Oasis Gas Boiler Error Codes

Oasis Gas Boiler Error Codes Error code E1 It shows that there is no ignition. The flame ionization sensor signals a failure of the unit. This sensor-electrode detects the presence of a flame and blocks the operation of the Oasis gas boiler in case of incomplete combustion of the main burner device or in case of difficulties with the flow of gas. Blocking occurs after 3 unsuccessful launches. To resume the workflow, you must press and hold the Reset key.

Gas valve malfunction – The operation of the gas valve is controlled by an electronic board. This component is tested by measuring resistance and voltage. If it is found that the values ​​differ from the standard parameters, the valve should be replaced with a new one. There is no gas supply to the apparatus – There is a valve in the gas distribution system that limits the flow of gas fuel. Consequently, a failure at the start of the device can be observed due to a blocked tap. Incorrect contact or no signal from the flame ionization sensor. Faulty control board – When the ignition cycle is normal, but the boiler immediately died out, then most likely the electronics do not detect a flame. Therefore, it needs to be checked.

Problem with overheating of the Oasis boiler heat exchanger. The device is blocked. Overheating thermostat trips – The temperature sensor and overheating thermostat are usually installed on the outlet pipe of the main heat exchanger. The main purpose of the thermostat is to ensure the safety of the appliance from an unnecessary increase in temperature. An emergency situation may occur due to problems in the thermostat, temperature sensor, as well as in case of malfunction of the main circulation circuit. Damaged temperature sensor – The electronic board receives an incorrect signal or the contact between the electronic board and the sensor is broken. The overheating thermostat is out of order – If the sensor is operational, but a real overheating of the liquid has occurred, then most likely there is a problem with the circulation of the coolant of the main circuit.

Oasis Gas Boiler Error code E9

Indicates that the system pressure level is low. The main reasons contributing to the appearance of this malfunction: low fluid pressure in the heating circuit. There is no contact between the control board and the pressure sensor. The pressure switch is faulty. You must first check the pressure gauge values. Usually the problem is eliminated with the use of a make-up tap, which is designed to fill the heating system with water. If the accident continues, then most likely there is a water leak. The circulation pump, primary heat exchanger, relief valve, damaged seals and gaskets, make-up valve and other parts can leak. Leakage is determined at the time of external inspection of hydraulic components.

Lack of traction. In order to ensure the correct and stable operation of the Oasis boiler, it is necessary to organize a draft for the exhaust gases to be removed so that they do not enter the living quarters. The smoke output is monitored by electronics, and if there are some problems, the draft sensor will turn on and the boiler will stop working. The main factors in which there is a lack of traction: small-sized diameter of the chimney channel, incorrect design, clogging with dirt, ice on the inner wall.

Reducing the size of the outlet channel entails a lack of thrust. Exceeding the permissible length of the flue pipes – Read the installation instructions for the gas appliance carefully and check that all the necessary requirements are met. Too much horizontal flue pipe can lead to loss of required draft. Traction sensor failure – When exposed to vacuum in the supply tube, a slight click will be noticeable. Disruption of contact between the control board and the draft sensor, there is condensate, as well as incorrect connection of the tubes to the pressure switch. Fan defective – The fan impeller is clogged. The fan shaft is not lubricated, so it does not increase the required speed. There is no contact between the electronic board and the fan.

Error E4 Oasis Gas Boiler

The DHW temperature sensor is not working correctly. This means that the DHW temperature sensor is out of order or the temperature required for operation is too high. The main factors due to which this malfunction occurs: the DHW temperature sensor is faulty. The contact between the electronic board and the DHW temperature sensor is broken. The control board has failed. When the DHW temperature sensor is good and firmly in contact with the electronic board, but at this moment the unit gives an error, then the electronic board is probably faulty.

Error E6 Oasis Gas Boiler

Problems during ignition. This situation is issued if there is no ignition or there is an attenuation of the burner flame. The contacts between the ignition device and the flame sensor, as well as between the electronic board and the gas valve, should be inspected. The main factor in the extinction of the flame of the burner may be insufficient draft.

Error E5 Oasis Gas Boiler

Refusal to determine the temperature by the heating system sensor. This circumstance indicates a malfunction of the temperature sensor of the heating circuit or the operating temperature has been exceeded. An open in the heating system temperature sensor circuit – This problem can occur if the connection of the temperature sensor to the control board is broken, or the temperature is below the recommended one.

After five seconds have elapsed following the detection of a malfunction, the Oasis boiler should return to correct operation if the malfunction occurred spontaneously. It is necessary to make sure that there is no moisture on the sensor connector and the controller connector. If there is no moisture, it is necessary to change the sensor. There is a short circuit in the temperature sensor of the heating circuit – This situation can occur when there is a short circuit in the temperature sensor circuit or the liquid temperature is much higher than required. First of all, you should measure the resistance of the sensor. If the resistance readings do not meet the requirements, you need to change the sensor. If the installation of a working sensor does not contribute to the result, change the electronic board.

Code E7 Oasis Gas Boiler

Malfunctions with the circulation pump or there is an air lock in the heating line.
