Bugatti Gas Boiler Error Codes When the boiler fails, it stops working, the protection is triggered. First of all, you need to open the instructions and find out what the error code means, often this error simply requires a reboot of the system, something the owner can do too. Below we give the error codes that the user can theoretically fix on his own.
Bugatti Boiler Error Code Solutions
Bugatti Boiler Error Code E01 (BC)
It indicates that the ignition system is faulty. The signal comes from the flame control sensor. This component detects the presence of a flame and interrupts the operation of the Federico Bugatti boiler during limited combustion of the main burner or in case of interruptions in the gas supply. The termination of work occurs after three unsuccessful starts. To restore functions, you must press and hold the reset key. Gas valve failure – The action of the gas valve is controlled by the electronics board.
This part is checked by measuring resistance and voltage. If it is found that the values differ from the standard characteristics, the valve should be replaced with a working one. There is no gas inflow to the unit – A valve is installed in the gas distribution scheme that shuts off the flow of gas fuel. As a consequence of this, a malfunction at the time of starting the device may occur due to a closed valve. Insufficient contact or no signal from the ionization flame sensor. The control board has a malfunction – When the ignition process is normal, but the unit immediately goes out, it can be assumed that the electronics cannot detect the flame. Therefore, it is necessary to diagnose it.
Bugatti Boiler Error Code E02 (HL)
Federico Bugatti boiler overheating problems. The device is blocked. The overheating thermostat has switched on 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. An accident may occur due to problems in the thermostat, temperature sensor, as well as in case of difficulty in the operation of the main circulation circuit. Temperature sensor failure – An incorrect signal comes to the control board or the contact between the sensor and the control board is broken.
Damage to the overheating thermostat – If it is in good condition, but a real overheating of the coolant is detected, then, apparently, there is a violation of the circulation of the coolant in the heating circuit. The main heat exchanger or the filter element of the main circuit is clogged (insufficient circulation process indicates an increased heating temperature of the liquid). Malfunction of the circulation pump or there is a blockage of air in the heating system.
Bugatti Boiler Error Code E04 (LP)
Indicates low pressure inside the system. The main reasons due to which this failure occurs: a decrease in the pressure of the coolant in the heating circuit. There is no contact between the electronic board and the relay-sensor. Defective pressure switch. First of all, you should find out the results of the pressure gauge reading. As a rule, failure can be eliminated by using a make-up tap, which is designed to add water to the system. In the case when a repetition of the problem is observed, then there is probably a coolant leak. The hydraulic pump, main heat exchanger, excess pressure relief valve, damaged gaskets, make-up valve and other components can leak. Leakage is determined visually when inspecting hydraulic components.
Bugatti Boiler Error Code E05 (AF)
No traction. In order to ensure the correct and stable functioning of the Bugatti gas boiler, it is necessary to organize a draft for the removal of exhaust gases so that they do not enter the room. The smoke output is monitored by electronics, and when any malfunctions occur, the draft sensor will turn on and the gas appliance will be blocked. The main factors that contribute to the lack of draft are: small-sized diameter of the chimney channel, installation defect, clogging with dirt, ice on the inner wall. The narrowing of the chimney leads to weak draft. The chimney pipe is too long It is recommended to carefully read the instructions for use of the appliance and check that the mandatory requirements are met.
The long horizontal section of the flue pipe leads to a weakening of the required draft. Draft sensor damage – When a vacuum occurs in the inlet tube, a soft click will be heard. Poor contact of the control board with the pneumatic relay-traction sensor, the presence of condensate, as well as improper fastening of the tubes with the pneumatic relay sensor. Damaged fan parts – There is a blockage in the fan impeller. There is no lubrication on the fan shaft, so it has low speed. Lost contact between fan and electronic board.
Bugatti Boiler Error Code E07 (OB)
The temperature sensor for hot water is not functioning correctly. This code means that the DHW circuit temperature sensor is damaged or the temperature required for operation is too high. The main factors that may cause this problem: the DHW temperature sensor is broken. The contact between the DHW temperature sensor and the electronic board is broken. Failure of the electronic board. If the DHW temperature sensor is working and is in stable contact with the control board, although the boiler gives an error, then the electronic board is probably out of order.
Bugatti Boiler Error Code E11
Ignition problems. This code may be issued if there is no ignition or there is a burner flameout. It is recommended to check the contacts between the ignition unit and the flame sensor, and also between the electronic board and the gas valve. The main factor in flameout is the lack of thrust.
Bugatti Boiler Error Code E06 (HB)
The heating circuit temperature sensor is not functioning properly. This situation means that the temperature sensor in the heating system is faulty or the temperature required for operation has risen. The circuit of the temperature sensor of the heating circuit is damaged – This malfunction occurs when the contact of the temperature sensor with the control board is broken, or the temperature is lower than recommended. Within 5 seconds after recognizing a malfunction, the Bugatti boiler should return to correct operation, in case the malfunction occurred by accident. It is necessary to make sure that there is no moisture on the temperature sensor connector and the electronic board connector.
If there is no moisture, it is recommended to change the temperature sensor. There is a short circuit in the temperature sensor in the heating circuit – This situation most often occurs when the temperature sensor circuit is short-circuited or the water temperature is above normal. The first step is to measure the resistance of the temperature sensor. If the resistance values do not match the required ones, it is recommended to change the temperature sensor. When installing a new sensor fails, repair the board.
