Haier Boiler Error Code Solutions

Haier Boiler Error Code E1

It indicates a faulty ignition system. The ionization flame sensor that monitors the ignition reports a malfunction. This part detects the presence of a flame and stops the Haier boiler during limited combustion of the main gas burner or in cases of gas failure. The termination of work occurs after three unsuccessful inclusions. To resume operation, press and hold the reset button.

Faulty gas valve – The action of the gas valve is controlled by the electronics board. Diagnostics of this element is carried out by measuring resistance and voltage. In the event that the values ​​differ from the nominal characteristics, it is recommended to replace the valve. There is no gas supply to the boiler – A valve is installed in the gas distribution device, which can block the flow of gas. As a result, a failure at the start of the boiler can be observed due to a closed tap. Insufficient contact or no pulse from the ionization flame sensor.

The electronic board is damaged – When ignition is carried out correctly, but the device immediately goes out, it can be assumed that the control board cannot detect the flame. Therefore, it needs to be tested. Ignition failure. This code may occur if the ignition does not work or the burner flame is extinguished. It is necessary to check the connections between the ignition device and the flame sensor, and also between the gas valve and the board.

One of the reasons for the extinction of the flame of the burner may be unsatisfactory draft. a failure at the start of the boiler can be observed due to a blocked tap. Insufficient contact or no pulse from the ionization flame sensor. The electronic board is damaged – When ignition is carried out correctly, but the device immediately goes out, it can be assumed that the control board cannot detect the flame. Therefore, it needs to be tested.

Haier Boiler Error Code E2

The heat exchanger in the Hayer boiler is overheated. The device is blocked. Overheating thermostat activated – The temperature sensor and overheating thermostat are usually installed on the outlet pipe of the primary heat exchanger. The main task of the thermostat is to ensure the safety of the device from an unnecessary increase in temperature. A malfunction most often occurs due to problems in the thermostat, temperature sensor, as well as a malfunction in the main circulation circuit.

Damaged temperature sensor – The control board receives an incorrect signal or poor contact between the control board and the sensor. The overheating thermostat is out of order – When the sensor is suitable for operation, although there is a real overheating of the coolant, then, apparently, there was a violation of the circulation of the coolant of the heating circuit. The main heat exchanger or the filter element of the heating circuit is clogged (low circulation level means high heating of the coolant). Malfunction of the circulation pump or there is an air lock in the heating system.

Haier Boiler Error Code E4

Indicates low pressure in the system. The main factors causing this problem: low fluid pressure in the heating circuit. Lack of contact between the electronic board and the relay-sensor. The pressure switch is faulty. First you need to look at the readings of the manometer. Usually the problem is fixed by using a make-up tap, which is needed to add coolant to the heating system. When the accident repeats again, then most likely there is a coolant leak. Leakage may be the circulation pump, main heat exchanger, relief valve, worn gaskets, make-up valve and other components. A leak can be found when inspecting the hydraulic components.

Haier Boiler Error Code E3

Lack of draft in the Haier boiler. In order to ensure the correct and uninterrupted operation of the apparatus, it is necessary to create a draft to remove combustion products so that they do not enter the room. The smoke output is monitored by electronics, and if some problems arise, the draft sensor-relay will work, and the unit will stop working. Possible reasons why there is no draft: insufficient size of the flue duct, inaccuracy during installation, clogging, icing of the inner wall.

Limiting the size of the chimney can cause a lack of draft. The chimney pipe is too long It is necessary to carefully study the instructions for using the gas appliance and follow all the necessary requirements. Too long a horizontal section of the chimney can cause a lack of the necessary draft. Malfunction of the pressure switch-draft sensor – If you create a vacuum in the supply pipe, you can catch a characteristic click. There is no contact between the electronic board and the pressure switch-draft sensor, there is condensate, as well as poor connection of the tubes to the pneumatic relay. Fan defective – The fan impeller is clogged. There is not enough lubricant on the fan shaft, so it does not increase the required speed. There is no contact between the control board and the fan. Accordingly, it does not increase the necessary speed.

Haier Boiler Error Code E7

The hot water temperature sensor is not working properly. This circumstance indicates the failure of the temperature sensor of the DHW circuit or the operating temperature has been exceeded. The main reasons due to which this malfunction appears: the temperature sensor for hot water supply is damaged. The contact between the DHW temperature sensor and the control board is broken. Control board failure. When the DHW temperature sensor is working and correctly connected to the electronic board, but at this moment the device gives an error, then the electronic board may have failed.

Haier Boiler Error Code E6

The temperature sensor on the heating system does not work correctly. This code indicates a malfunction of the temperature sensor in the heating circuit or the recommended temperature is too high. Open circuit of the temperature sensor in the heating circuit – This malfunction can occur if the temperature sensor is interrupted from the electronics board, or the temperature is below the nominal value. Five seconds after recognizing a malfunction, the Hayer boiler should return to normal operation if the malfunction occurred spontaneously. Make sure that there is no moisture on the sensor connector and the electronic board connector.

If there is no moisture, replace the sensor. The appearance of a short circuit of the temperature sensor of the heating circuit – This situation may occur due to a short circuit of the contacts of the temperature sensor or the temperature of the liquid is above normal. Initially, you should measure the resistance of the temperature sensor. If the resistance indicators differ from the nominal ones, it is necessary to replace the temperature sensor. When replacing the temperature sensor does not help, change the controller.

The Haer boiler was put into operation two years ago. Recently, almost regularly shows the error code E1. After resetting with the reset button, the device occasionally starts up normally, but this happens very rarely. I recently removed the air intake plug and it started working better. What might be wrong?

If it gives a chimney-related error, you must open the safety covers. This will help draw air out of the room. Next, check the chimney pipe for ice and, if necessary, remove it. In the event of a fire accident, it is recommended to find out if gas is supplied to the house.

Often, an error with code E6 is on the boiler. Help me figure out what it means?

This code indicates to you a malfunction of the heating NTC temperature sensor. Most likely, it needs to be changed.

Why did the Haier boiler not turn on? At the same time, it regularly gives an error E2. What should be done?

This malfunction usually appears due to some problems with the thermostat, temperature sensor, as well as malfunctions of the main circulation circuit. The heat exchanger may have overheated. If the thermostat and temperature sensor are OK, then the problem is in the electronic board. Need to change it.

Because of what, the unit cannot start and gives an E4 error? The pressure in the system is normal, no leaks are visible. Tried to turn off the power, but the problem does not go away. Help how to fix it?

The malfunction may indicate low water pressure in the heating circuit. In this case, it is necessary to check the water level sensor. It is possible that it is broken.

The problem of the device is as follows: the DHW is turned on at a temperature of forty-five degrees. When you turn on the hot water, the gas burner device lights up for a short time and then goes out. This cycle happens frequently. From the mixer pours cold water, then warm (not hot). Error code E2 flashes repeatedly. Why is this happening?

This code indicates the boiling of water in the DHW circuit. Most likely, the heat exchanger is clogged, or the thermostat has incorrect settings.

The following error has occurred. During ignition, the unit displays error E1. When restarted, it turns on normally, but only the gas burner lights up, you can hear a few clicks, and the error is displayed again. I replaced the ionization electrode, flushed the flow sensor, turned the plug over, but there was no improvement. Has anyone met with this?

This problem occurs in three cases. Damage to the control electrode. Difficulties with gas supply. Damaged control board.

The device stopped working on its own and the E4 code is issued. What can be done?

There is no water in the unit or the pressure sensor is broken. Fill the system with fluid first.

The gas appliance switches off with error message E3. Cleaned and blew – helps for a while. What happened?

This code reports insufficient draft and the flue gas system needs to be checked. Presumably, the membrane may stick. In another case, we advise you to contact a specialist for a thorough check of the unit with further testing.

There is a Hayer boiler. An error with the E6 code began to come out. The device itself works, we adjust the water temperature manually. When it was installed, it seems that overheating began, because the automatic temperature mode was turned on. We did not install an external air temperature sensor. What is the reason?

Most likely, the hot water temperature sensor has failed. Sometimes the electronics board fails.

The unit performs functions for about 4-5 minutes, after which the burner turns off, and error E3 occurs. It flashes for no more than a minute, the burner turns on again, and the device operates normally for another 5-6 minutes, and so many times. This code, judging by the instructions, indicates the activation of the draft sensor, although the chimney channel is not contaminated, the flue gases exit normally. Help me figure out what’s wrong?

In this case, the main reasons preceding the lack of thrust are: damage to the draft sensor. The contact between the pneumatic relay sensor and the electronic board is broken. Condensation in the pipes, as well as incorrect fastening of the pipes with the pneumatic relay sensor. Damage to fan components. He probably does not develop the required speed.
