Neva luxury boiler error 03 what to do. Heating systems for country and country houses

Gas water heater Neva Lux from domestic manufacturer is a technically complex product. The entire cycle of work from turning on the column to heating the water is controlled by automatic equipment, which malfunctions over time. For a better understanding of the malfunction, the company's engineer placed an indicator window on the front panel, in which one or another error code is displayed during an emergency stop. Let's consider them in more detail.

ATTENTION! Operations on maintenance repair of gas water heaters associated with the disassembly of its gas or water communications must be carried out by qualified craftsmen. Self repair can give the opposite effect to the raft prior to purchasing a new apparatus.

Error E0 - lack of gas

Reason # 1. NSTurn off the gas at the descent to the column or light gas stove... Lack of gas in the pipeline due to work on the pipeline. The servo motor (block with solenoid valves) is out of order.

This error cannot be eliminated on your own. You will need the help of a service worker. Contact a specialized service center for repair.

Error E1 - no flame

Ignition clicks for about a minute the burner does not ignite. The electronic control unit does not see the presence of a flame and the column goes into emergency mode.

Reason # 1. The presence of air in communications... Didle time of the column, or after its installation, the operation of the ignition burner will occur only after air has been removed. The system should be purged by constantly turning on the column. Since the ignition lasts no more than a minute, after completion you should reopen the water tap until the ignition occurs.

Reason # 2. Lack of gas in the cylinders or the valve on the lowering to the dispenser is closed... NSOpen the shut-off valve fully. Check gas cylinders with liquefied gas. Replace them if necessary.

Reason number 3. There is no contact between the unit and the flame sensor... It is necessary to carry out maintenance of the contacts coming out of the electronic unit, if necessary, clean them, press them to good connection worn out to replace.

Reason number 4. Flame presence sensor outside the flame zone... Adjust the position of the flame detector so that its electrode is in the gas combustion zone. Make sure that the electrode does not touch other metal components. Clean the electrode from carbon deposits.

Reason number 5. The gap between the ignition plug and the igniter is broken... From constant heating and cooling, the pilot burner nozzle is deformed, which increases the gap to the spark plug. Every two years, or with a regulated maintenance, the gap should be adjusted 4 ... 5 mm.

Error E3 - breakdown of automation

Triggering solenoid valves occurs before the signal from the water flow sensor appears.

Reason # 1. Breakage or malfunction of solenoid valves... Call the wizard for diagnostics.

Reason # 2. Electronic control unit defective... Invite the master to the house.

Error E4 - premature inclusion

The flame detector gives a signal about the presence of a flame until the signal from the water flow sensor appears.

Reason # 1. You are trying to turn on the speaker using a different power source (matches).

Reason # 2. The electronic control unit is out of order.

Error E5 - no signal from the flow sensor

There is no signal coming from the water flow sensor (open circuit).

Reason # 1. The circuit is open between the electronic unit and the water flow sensor... Use a tester to check the circuit and also check the sensor for an open.

Error E7 - lack of gas

The column goes out after turning on. Failed ignition attempt. Process: the pilot ignites, then the main burner, then everything goes out and the process is repeated again.

Reasons # 1. Low gas pressure... Open the gas cock at the lowering to the column. Invite a specialist to your home to measure the gas pressure in the system and further configure the column. You should also purge and clean the gas filter.

Reason # 2. The flame ionisation sensor is not in the range of the main burner fire... Adjust the sensor. Install the electrode so that the main burner fire flushes from both sides. Carbon deposits may have formed on the sensor, which makes heating weak - clean and adjust the sensor.

Reason number 3. The mechanism in the water unit is stuck... Increased salt deposition on moving machinery leads to seizing and stopping. A stuck rod of the water unit leads to a permanent short circuit of the flow sensor. In this case, it is necessary to dismantle the water part and carry out preventive work: lubrication of the rod, replacement of rubber gaskets.

Error E8 - no traction

The column turns off after 2..5 minutes of work. Restarting becomes possible only after cooling down - 2..3 minutes.

Reason # 1. Lack of draft in the chimney... Clean the chimney.

Reason # 2. Soot on the heat exchanger... Increased accumulation of soot on the heat exchanger, which obstructs the passage carbon monoxide into the chimney. To fix the problem, the column should be serviced.

Reason number 3. The traction sensor is faulty... The traction sensor works for rupture. Over time, the sensor becomes very sensitive to vibrations and can turn off the column during heating. Therefore, with this error, the sensor will be checked for operability.

Error 99 - short circuit

Numbers 99 blink on the display for a while, then the column turns off with an error message LO.

Reason # 1. Closed the water temperature sensor(makes sure that the heat exchanger does not overheat). The error can be eliminated only by replacing the sensor and its wires.

Error H1 - insufficient heating

The column does not heat the water to the specified temperature.

Reason # 1. Set heat at high pressure. The column cannot cope with heating the amount of water that passes through the column. Reduce head.

Reason # 2 ... Burner clogged with dust. If you notice that the gas is burning orange and the flame is sluggish and elongated, it is time to clean the burner. If you neglect cleaning, then given error will appear constantly. The efficiency of the column will be halved. A lot of soot will appear.
