Decryption
According to the instructions for the Vailant boilers of the TurboTec series, the following messages are displayed on the display:
- F - codes of malfunctions (failures);
- P - setup programs;
- d - diagnostics of the Vaillant boiler;
- S - states.
The indication 5er (Ser) is not an error indicating a malfunction of the heating unit. The code reminds the user to service the burner of the Vaillant boiler. The frequency is determined by the operating hours of the node, set in the range 0–3000. Symbols do not affect the operation of the equipment, it continues to function in the specified mode.
Ser error is displayed on the Vaillant boiler control panel
How to proceed
The user himself decides whether this hint is needed or not. But failure to adhere to the maintenance periods recommended by the Vailant manufacturer negatively affects the efficiency and durability of the equipment, and often causes errors and emergency blockages.
Clean the burner
The nozzles are gradually clogged with dust, soot, the amount of combustible mixture entering the chamber decreases, the intensity of the flame weakens. The node is cleaned regularly, which is what the 5er (Ser) error reminds of.

Methodology
The work is done with a vacuum cleaner and a toothbrush. Dirt enters the holes of the nozzles from the walls of the chamber, the lower part of the body of the heat exchanger. They are also clogged with sludge penetrating through the filter.
- Disconnect the Vailant boiler from the network, remove the casing of the unit, the cover of the combustion chamber.
- Gently brushing the surfaces with a brush, suck up the smallest fractions with a vacuum cleaner. Time for such work is spent no more than 10-15 minutes, the services of a service master are not needed.
On the Internet there are "useful tips" by a number of users on removing dirt from the chamber with a jet of air. Doubtful recommendation: dust, soot will scatter around the room, clog the nozzles - there is only harm from such maintenance.
The parameter can be controlled in menu item d 84 (2nd level code).

Change the number of hours, and the error 5er (Ser) will be displayed more often or less often. When entering, note that 1 corresponds to 10 hours
When determining the period between burner maintenance, take into account: the period and intensity of operation of the Vailant boiler, the quality and type of "blue fuel" (main gas, liquefied gas), the features of the installation site (room dimensions, ventilation efficiency, cleanliness in the room and a number of other factors)
How to clean a gas boiler in a few simple ways
A gas boiler installed in a house for heating and heating water, like any other mechanism, requires care and maintenance. One of the main procedures that serve to ensure long-term and uninterrupted operation of the device is its cleaning before and after the heating season. This includes:
If you have no idea about the internal structure of the boiler, then call a specialist
It is possible to wash the heat exchanger at home, but you need to know and follow some rules. The duration of cleaning depends on the thickness of the layer of organic and mineral deposits and lasts 1.5 - 4 hours. When choosing a cleaning method, one should be guided by the degree of contamination, the availability of special equipment and reagents.
Time to clean the heat exchanger
When it is necessary to flush the heat exchanger of a gas boiler is a common question. There are a number of signs by which you can be sure that the time has come.
One of the main ones:
- constantly on gas burner;
- the circulation pump has become noisier, which means it is overloaded;
- heating radiators began to heat up longer in time;
- gas consumption increases;
- the water pressure has become weaker (the first sign for flushing a double-circuit boiler).
In addition to cleaning the chimney, they also clean the boiler from soot. If the operation of the chimney is difficult, then in some cases it turns off, but this does not happen when clogged with soot. Combustion products are released into the air, and the owners breathe them.
It is recommended to clean the boilers once a year, especially if there is a year-round operation.
