Neva heating equipment is one of the most popular among users. The technique of this brand is adapted to Russian realities, it works stably under reduced pressure in the pipeline. But this does not mean that operation is without breakdowns. Errors of the Neva Lux boiler will indicate malfunctions in the system, and their value will help restore the operation of the equipment.
Features of the operation of boilers "Neva"
The gas boiler "Neva" is presented in wall and floor versions. Single-circuit devices can heat an area of 180 m², characterized by low energy consumption. They operate on trunk and liquefied fuels. Since the combustion chamber has water cooling, it is possible to connect to an external thermostat. The organization of the chimney is carried out to the main shaft or to the turbo nozzle.
Double-circuit units are presented by Neva Lux models. The design includes two heat exchangers for heating and hot water (DHW). For example, in the Neva Lux 7224 model a bithermic radiator is built-in. This is a tube in a tube where water is simultaneously heated for two circuits.
Control of devices mechanical and electronic. Special sensors monitor the operation of the boiler, in case of malfunctions send a signal to the control module. Then a fault code is displayed. To find out its meaning, you can look at the instructions.
Neva error codes
We list the main malfunctions of the device, and also indicate options for resolving the problem.

Other problems
Not all failures are displayed with error codes. Some can be identified by signs.
The boiler does not turn on.
- Check for electricity if the boiler is connected to the mains.
- The fuse on the electronic board does not work.
- Circuit board shorted due to leakage. Inspect all components and parts for leaks.
The appliance pops on ignition.
- Ignition power or pressure set incorrectly. Adjust the settings.
- Clean the chimney, provide adequate ventilation in the room to maintain traction.
- Clean the burner block from soot and soot.
If there is a gas smell in the room, close the shut-off valve. Contact the gas service.
Weak water pressure when opening the mixer.
- Pressure has dropped in the line. Wait for recovery or install a pump.
- Remove dirt and scale from the water filter and heat exchanger parts.
The temperature of the coolant exceeds the set.
- Dilute the hot stream with cold, increase the speed of circulation.
The standby mode is turned on, the panel does not work, “-” lights up on the display.
- The reason is the voltage drops in the network. As soon as it is restored, the equipment will resume work. It is recommended to install a stabilizer.
Having familiarized yourself with the trouble codes, you can proceed to resolve them or contact a service center. Good luck
