Gazlux gas boiler error codes help determine the cause of the problem. In some models they are shown on the display, in others the blinking indicators become a signal. Problems can be caused by both external factors and internal breakdowns. How to find and fix a malfunction? Our recommendations will help you.
Construction and operation of boilers
Gas equipment "Gaslux" was developed in Russia, but the assembly is carried out in China. These are dual-circuit devices that are designed for hot water supply (DHW) and space heating. They are available in three series:
- Economy (Economy). Features and functionality of boilers can be identified by name. For example, Economy B-18-C1 belongs to the economy class, has an atmospheric chamber, its power is 18 kW. The control is mechanical, rotation indicators are located on the panel. Errors are indicated by flashing indicators.
- Standard The decoding of the name of the Standard B-24-T1 model looks like this: standard series, closed camera. Combustion products are forcibly discharged. Power is 24 kW. The presence of the letter F indicates the additional function "Anti-freezing". Using the button control, you can set the modes. Progress is monitored on the LCD.
- Premium (Premium). There is the possibility of programming, modern functionality, color LCD screen. Faults are displayed as symbols on the display.
Any Gazlux equipment has a bithermic heat exchanger, magnetic protection against scale. The main "body" that controls all the processes of the device is the electronic board. It includes a self-diagnosis system, due to which a fault code is displayed on the screen.
Common problems and errors
The code may appear in such cases:
- The flame in the burner has gone out;
- Combustion products are not removed, enter the room;
- The technique is overheating;
- The pressure in the system drops.
Causes of malfunctions can be either external or internal. For example, the lack of ventilation affects the quality of the flame, low pressure in the line - on the circulation of water. In critical situations, the operation of the equipment will be blocked until you fix the breakdown.
Errors for the Standard and Economy series
The blinking LEDs become a fault signal. Pay attention to the diode number 5.
E1 (E01)
The first upper power lamp is constantly on, the lower diode blinks red once per second. The thermostat or the exhaust gas sensor has tripped. Fan pressure is abnormal. Smoke is badly removed.
- Faulty fan. Replace part;
- Inspect the chimney and chimneys for obstruction. Clean them from soot and debris, restore traction;
- The outer part of the chimney is frozen, ice interferes with the flow of air. Clear the mine from ice;
- Check the wiring and pressure sensor tubes for damage.
Error E2
The second power lamp on top lights up, at the bottom the indicator lights up in red. The temperature sensor has broken on the feed line.
- Diagnose the sensor;
- Measure the resistance. Normally, the results should not deviate from 10 kOhm. In other cases, replacement of the part is required.
E3 (E03)
The third diode glows from above. The bottom indicator is red. The hot water temperature sensor is out of order. It is necessary to carry out a similar operation as with E2.
Error E4 (E04)
The red light and the 4th indicator above are constantly on. System overheating up to 95 degrees. The thermostat has tripped. The reason lies in poor water circulation. What caused the problem:
- Circulation pump out of order. Repair or installation of a new element;
- Air has accumulated in the system. Release the surplus;
- The stream of water is interfered with by garbage, a foreign object. Clean the blockage.
E6
The first and fifth diode on top glows. A red light is on from below. No flame is recognized after ignition. Operation blocked by ionization sensor. Possible reasons and what to do:
- Problems with fuel supply. Unscrew the gas valve, wait until the supply is restored. Inspect for obstruction burner, nozzles, filters. Make sure the supply valve is working;
- The ignition system has failed. Carry out repairs;
- Broken flame electrode. Strip parts, replace electrode.
E7 (Eb)
The second and fifth indicators above and the red diode below are on. Flame control error.
- Closed the ionization electrode. Install a working item;
- Faulty control module. It is better to contact the master.
If the lower lamp lights up red and the power indicators flash alternately, it means that a flame is detected when the fuel valve is closed. Need valve or main board diagnostics.
EP
At the bottom, the diodes flash red and green. The problem is indicated by a beep. Reduced system pressure. Held:
- Replacement pressure sensor;
- Make-up to increase pressure;
- System cleaning, air removal;
- Installing a working circulation pump.
Sometimes the system signals the status of the boiler:
- The lower diode blinks green four times, the upper ones are lit - the “Anti-freezing” mode is on;
- Once every three seconds, the lower diode glows green, the lights on top of it light up. Pump coast is on, burner is not running.
To restart the equipment and reset the error, press ON / OFF - RESET. If nothing has changed, turn off the power to the device. If the code does not disappear, it is better to contact the service center.
