Features of operation and diagnostics

During the connection, operation and maintenance of the Vaillant gas heating boiler, some malfunctions may occur. Models in which an electrical control system with a screen is installed makes it possible to understand what exactly does not work in a given situation.

To understand what to do in certain cases, consider the common error codes of the Vilant gas boiler, and what needs to be done if they occur. If several errors have occurred at once, they are displayed alternately for about 2 seconds.

Icon designations can start with the letter F (error) or S (status). Specifications and codes that are inherent in each specific model are spelled out in the operating instructions.

The most common error codes for Vilant boilers

F5

Error F5 means a rupture of the external flue gas sensor. Possible causes include incorrect operation of the flue gas sensor, disconnected plug or damaged cable, or incorrectly fitted spare resistor. The code is valid only for the mounted Vailant Atmo model.

5ER

If the display alternates between the water temperature and the 5ER (or SER) error, this is a reminder that it's time to spend maintenance devices.

The user himself can set the frequency of how often this reminder pops up. The value in the item for diagnostics D.084 is set in the range from 0 to 3000 hours with an interval of 10 hours (the number 300 corresponds to 3000 hours). To completely disable this function, enter “---“ instead of a numeric value.

F15

Fault F15 indicates a short circuit in the outdoor flue gas sensor. Presumably, there was a short circuit with the sensor plug body, a short circuit inside the harness with wires, or the sensor itself is faulty. Shown only in Vaillant Atmo wall-hung boilers.

F20

Error F20 (F20) detects that a protective shutdown of the device has occurred due to the fact that the safety limiter of the STB temperature indicator has worked. It triggers when the maximum permissible temperature is exceeded.

This may happen due to the fact that the ground contacts of the wiring harness with the housing are incorrect, breakdown of the NTC return or supply line (weak contact). A breakdown through the ignition wire, electrode or ignition plug is also possible.

F21

Error F21 means emergency shutdown of the flame supervision machine GFA.

F22

Error F22 (F22) indicates operation protective shutdown due to insufficient water. The reasons for this are a malfunction of the pump cable or toggle switch with an insufficient amount of water, the pump does not work or is blocked, or it has too little power.

F23

Error F23 detects an emergency shutdown due to a too large temperature difference between the sensors located on the supply and discharge lines.

• Very low pump powerwhy the pressure on one side drops;
• pump blocked;
• return and direct line NTC sensors are not in their places.

F24

Error F24 signals an emergency shutdown if the temperature rises too quickly. This means the presence of air in the device, reduced pump performance, blockage or very low pressure in the heating system. The gravity valve may be incorrectly connected or blocked.

F26

Error F26 means that the flow of the gas valve is not detected stepper motor due to breakdown of gas fittings. It may be that the servomotor of the gas fittings is not connected or the servomotor of the gas fittings is broken, the connector is incorrectly inserted into the board, or there is a break in the wiring harness.

F28

Error F28 (F28) indicates that the equipment did not turn on, a malfunction occurred when the device was started, and the ignition attempts were unsuccessful.

There are a number of options:

F29

Error F 29 (F29) expresses that the burner flame goes out during operation and further attempts to ignite are unsuccessful. Fuel supply may be temporarily interrupted, ignition transformer interrupted, or equipment improperly grounded.

F33

Error F33 (F33) reflects that the device for measuring pressure force does not turn on. After switching off the fan, the pressure switch does not disconnect the contact. Relevant for the Vilant Turbo TEK PRO line.

S33

Error S33 indicates that the device is locked and put into a 20-minute standby state, the heat exchanger frost protection mode has been activated. The reason is that the contacts of the relay of the air-gas path have not been connected. This condition can appear in the Vilant 242 Turbo double-circuit boiler.

F36

Error F36 (F36) - the thrust rollover sensor has recognized the release of combustion products. Indicates that the traction is too weak. Most likely, the chimney is clogged or the ventilation is closed. The elimination of this problem consists in cleaning the chimney, turning off the active hood over the stove and opening the window.

F37

Error F 37 (F37) means deviation of the fan speed (too fast or slow). The pressure sensor may be broken.

F38

Error F38 means that the fan is out of order and needs to be replaced.

F53

Error F53 indicates incorrect combustion settings.

Possible reasons:

F61

Error F61 indicates an error in the control of the gas valves. The cable harness connection may be damaged and a short circuit has occurred, the gas valve or the electronic board is faulty.

F62

Error F62 - delayed time for turning off the gas valve. It can be triggered if there is an extraneous light inside (the control electrode does not indicate flame attenuation).

F71

Fault F71 indicates a failure of the flow temperature sensor. It is probably defective or at a great distance from the supply line.

F72

Error F72 appears when the return or flow temperature sensor fails. It may be defective or a very large temperature difference in the direct or return line of the NTC sensors.

F75

Error F75 (F75) means that there is no pressure jump when the pump is turned on. There may be oxygen in the heating system or the pump or water sensor is not working correctly. To rectify the situation as soon as possible, the adjustable bypass is checked, an expansion tank is connected to the return line.

SER

The SER error is the same as the 5ER code (the letter "S" and the number "5" are displayed the same on the electronic display). After the problem has been eliminated, the errors are reset after pressing the "Reset" button or switching the boiler on and off from the network.

Other faults and how to fix them

If the reverse thrust diode blinks, then either it is faulty, or the combustion products are not completely removed, but enter the room. The repair instructions in this case are as follows: first, you should clean the chimney, then check the quality of ventilation.

The return flow sensor can then be replaced. Initially, during installation, it is important to comply with all safety requirements. Quite often the gas burner gets clogged, soot is deposited on it. It should be cleaned regularly to fully control the flame level.
