If the readings differ from the standard parameters, the valve should be replaced. No gas supply to the system – A valve is installed in the gas distribution system that can shut off the gas supply. As a consequence of this, a failure at the start of the device may occur due to a closed tap. Weak contact or the signal from the flame control sensor is not defined. The electronic board is damaged – When the ignition process is carried out normally, but the device suddenly goes out, it is possible that the electronics do not recognize the flame. Therefore, it is required to perform its diagnostics.
Problems at the time of ignition. This code is issued if the ignition is not working or if there is a flame failure of the burner. It is required to inspect the contacts between the ignition device and the flame electrode, as well as between the control board and the gas valve. The main reason for the extinction of the flame of the burner may be weak draft.

Royalthermo Boiler Error Code E2
The problem with overheating of the heat exchanger of the Royalthermo boiler. The device is blocked. The overheating safety thermostat has tripped – The overheating thermostat, as well as the temperature sensor, are in most cases placed on the outlet pipe of the primary heat exchanger. An important function of the thermostat is to protect the device from elevated temperatures. An emergency situation may occur due to problems in the thermostat, temperature sensor, as well as in case of malfunctions of the main circulation circuit.
Faulty temperature sensor – The electronic board receives an incorrect signal or a contact failure between the control board and the sensor. Faulty overheating thermostat – If the component is suitable for operation, but a real overheating of the liquid is detected, then it can be assumed that there is a violation of the circulation of the heating circuit coolant.
Royalthermo Boiler Error Code F4
There is a problem with the circulation pump or there is an air lock in the heating system.
Royalthermo Boiler Error Code E4
It indicates that there is not enough pressure inside the system. The main factors in which this problem occurs: low fluid pressure in the heating circuit. Lack of contact between the minimum pressure sensor and the electronic board. The pressure switch is faulty. First you need to look at the readings of the manometer. The failure can usually be cleared with a make-up valve that is designed to add coolant to the system. If the accident continues, then most likely there is a water leak. The hydraulic pump, main heat exchanger, safety valve, worn seal elements, make-up valve and other components may be leaking. Leakage can be found by visual inspection of hydraulic components and connections.
Royalthermo Boiler Error Code E3
Lack of traction. For the stable and safe operation of the gas unit, it is necessary to create a draft for the exhaust gases to be removed so that they do not enter the room. This is followed by automation, and if certain problems occur, the thrust sensor will work, and the device will be blocked. Possible sources of lack of draft: narrowed diameter of the flue duct, design mismatch, clogging, ice on the walls. Reducing the size of the flue duct entails a lack of traction. The length of the chimney pipe is exceeded. We advise you to carefully study the instructions for using the gas boiler and follow all the necessary requirements.
An excessively long straight section of the chimney pipe leads to a lack of necessary draft. The pressure switch – draft sensor is broken – If a vacuum forms in the inlet tube, then a slight click will be noticeable. There is no contact between the control board and the draft sensor, there is condensate, as well as incorrect connection of the tubes to the pneumatic relay. Damaged fan parts – The fan impeller is clogged. There is no lubrication on the fan shaft, so it has low speed. The contact between the electronic board and the fan is broken.
Royalthermo Boiler Error Code E6
The hot water temperature sensor is not working properly. This situation means that the DHW temperature sensor is out of order or the recommended temperature is too high. The main reasons preceding this problem: the hot water temperature sensor is not operational. Poor contact between the control board and the DHW temperature sensor. Damage to the electronic board. When the hot water temperature sensor is working and securely connected to the electronic control board, although the boiler displays an error, then most likely the electronic board is defective.
Royalthermo Boiler Error Code E7
Malfunction of the temperature sensor of the heating system. This code indicates a malfunction of the temperature sensor in the heating circuit or the operating temperature has been exceeded. A break in the heating circuit temperature sensor circuit – This problem most often occurs if the connection between the temperature sensor and the electronics board is broken, or the temperature is below normal. 5 seconds after the detection of a malfunction, the Royal Thermo boiler will restore normal operation if the malfunction occurs spontaneously.
It is required to check that there is no moisture on the connector of the temperature sensor and the connector of the controller. If there is no moisture, it is recommended to replace the sensor. There is a short circuit of the temperature sensor of the heating circuit – This problem occurs at the time of a short circuit of the contacts of the temperature sensor or the temperature of the water is higher than the nominal value. The first step is to measure the resistance of the temperature sensor. If the resistance characteristics differ from the standard, the temperature sensor must be replaced. If replacing the temperature sensor does not help, repair the board.
Boiler Royalthermo Aquarius in operation. This week almost daily shows the error code E1. After resetting with the reset key, the unit occasionally starts without problems, but this happens very rarely. I recently removed the air cap and it works better. What might be wrong?
When it starts to give a thrust error, you must open the protective covers. This will help draw air out of the living space. Then inspect the chimney for ice and clean if necessary. If there is a flame failure, it is recommended to check whether gas is entering the house.
Often the boiler shows the error code E7. Help me figure out what’s wrong?
This code indicates to you a problem with the temperature sensor of the heating system. Most likely, it needs to be replaced.
Why does the Royal Thermo Aquarius boiler not start? At the same time, it regularly starts to give an E2 error. How to fix it?
Such a failure can occur due to various problems with the thermostat, temperature sensor, and in addition, with difficult operation of the main circulation circuit. Apparently the heat exchanger is overheating. If the thermostat and temperature sensor are not broken, then the problem is with the control board. It needs to be replaced.
Why does the boiler not want to start and error code E4 is issued? The pressure in the system is normal, there are no leaks. Tried unplugging, but the problem persists. Help how to fix it?
The fault code usually appears when the water pressure in the heating circuit is reduced. In this situation, it is necessary to check the pressure switch. Apparently, that’s the reason.
The problem of the device is this: the DHW is turned on at 40 degrees. At the moment the hot water is turned on, the gas burner starts to burn and goes out almost immediately. This cycle occurs constantly. From the mixer flows either cold water or warm (not hot). Often an error code E2 is issued. What is causing this malfunction?
This fault indicates that the water in the hot water circuit is boiling. Most likely, there is a strong contamination of the heat exchanger, and the thermostat has incorrect adjustments.
There was such a problem. During ignition, the device shows an error code E1. When you reboot, it turns on, but the gas burner only lights up, a few clicks are heard, and after that an error is generated. I replaced the ignition electrode, flushed the flow sensor, turned the plug over, but the result was zero. Has anyone met with this?
This malfunction can occur for several reasons. Damage to the control electrode. Difficulties with gas supply. Damaged electronic board.
The unit has switched off autonomously and code E4 is displayed. How to be?
Lack of coolant in the unit or defective pressure switch sensor. First fill the system with water.
The unit aborts with error code E3. Cleaning and purging helped for a while. What can be done?
This code indicates a lack of draft, and we advise you to check the chimney channel. It is likely that the membrane is sticking. In other cases, it is necessary to contact a specialist for a thorough check of the device and subsequent it.
The house has a Royalthermo Aquarius boiler. Error E6 began to come out. The unit itself does the work, the temperature level of the liquid is regulated by a manual switch. When it was installed, apparently, overheating began, since the automatic temperature regime was turned on. The outdoor air temperature sensor was not installed. What is the reason and how to fix it?
The DHW temperature sensor is probably damaged. Otherwise, the control board is faulty.
The unit operates for approximately a few minutes, then the burner turns off, and error E3 comes out. It glows for about a minute, the burner starts up again, and the device works normally for another three or four minutes, and so on in a circle. This failure, judging by the instructions, means that the draft sensor has worked, but the chimney channel is clean, flue gases are discharged normally. I can’t figure out what is causing the problem.
In this case, the main reasons preceding the lack of traction may be: a malfunction of the pneumorelay-traction sensor. Lack of contact of the control board with the pneumatic relay-traction sensor. There is condensate, as well as incorrect connection of the tubes to the pressure switch. The fan is damaged. It seems that he is not able to develop the necessary speed.
