Selenium gas column does not ignite

Professional experts say that gas equipment is a potentially hazardous technique, therefore experts should repair it and carry out maintenance. You can independently figure out which parts are broken, and this will help to quickly restore the operability of the gas equipment, some problems can be easily corrected with your own hands.

Faults that do not affect the principle of operation of the gas water heater are eliminated by home craftsmen themselves. It is important to know the list and description of the most common breakdowns and follow the manufacturer's recommendations.

The gas column does not ignite

When a technical device refuses to ignite, there may be several reasons.

Broken igniter. When the igniter is defective, it cannot burn, in which case it is required to contact the gas service. A qualified technician will replace the defective element, it is not recommended to replace it yourself - this is a real danger.

In the units of the latest models, the presence of electronic ignition is provided, which means that if there is no ignition, the gas is cut off by the valve, and the supply of blue fuel is stopped.

The instructions for repairing gas water heaters describe what to do, sometimes it is enough just to replace the battery. When there are no recommendations in the instructions, the only way out is to contact the repair service.

If there is no ventilation draft, the gas water heater will never ignite, check the draft level with a paper strip - just bring the paper to the ventilation grill. We noticed that the position of the sheet does not change - there are indeed problems with traction. In this case, repairing the gas water heater with your own hands comes down to cleaning the ventilation wells.

A metal brush at the end of a long flexible wire will help you to do this yourself, but you should not expect approval of such actions from utility workers.

If the diaphragm in the mechanism is worn out, the burner does not work, this element deforms quickly, regardless of the cost of the equipment - for a maximum of 5 to 8 years.

To make sure that the membrane is defective, turn on the maximum water pressure, the home master can replace the part himself.

Operation of the geyser Selena - Actions to eliminate major malfunctions

_______________________________________________________________________________

There is a Selena SWH 20 SE3 gas flowing water heater in the house. Explain why it weakly began to heat the water? What can you advise me to do to fix this problem? The first problem is that the heat exchanger is clogged. Scale build-up on the heat exchanger housing makes it difficult to heat the water as needed, and the appliance starts to heat up the water unsatisfactorily. For this reason, the heat exchanger must be cleaned. Secondly, regular overheating of the heat exchanger. This indicates improper use of the device. The rise in temperature serves as a source of scale formation, which inhibits the heating of the liquid. In this situation, it is recommended to replace the heat exchanger. We use a gas water heater of the specified company at home. After four years of operation, the heat exchanger began to leak. The repair did not solve the problem, and after 3 months I bought a new unit. The installer said it should be cleaned and maintained annually. I cleaned and did prophylaxis. As a result, this device worked for three and a half years, and the reason for the failure is the same - a leak in the heat exchanger.What could be the reason for this? Probably, the water is of poor quality, and therefore the heat exchangers are leaking. At the dacha, the same model is connected. Help me understand why sometimes there is excessive heating of water? What kind of malfunction is this? Apparently, the problem is with improperly installed regulators. It is recommended to install for summer season. Use the gas knob to minimize the gas on the burner, and then add the water flow to the water heater. There is a problem with the Selena Turbo gas flow column. The wick starts to burn, I hold it in this position for about 5 minutes. Then I switch to the operating mode, but the device goes out. What does it depend on? We recommend that you dismantle the casing, remove the pipe supplying gas to the wick and clean it. In general, this operation must be performed at least once a year, preferably at the end of summer, when dust is clogged through the open windows into the gas supply pipe. Help me understand what the problem is when a gas water heater sometimes does not function well for heating. What do we have to do? It is possible that the burner flame is unstable, which indicates a diaphragm malfunction, and the pressure of the stem against the gas valve is very weak. You need to dismantle the water block from the gas device. Next, remove the cover from the water unit and check the membrane for deformations, and if it is unusable, install the whole one. A year ago, a gas water heater of this model was connected for the purpose of heating a private house. Recently there was a problem with ignition. When there is a request for DHW, the igniter is ignited. It ignites and suddenly goes out, and then the water heater starts up again. And so 2 or 3 times. Then the functionality of the unit is normalized. Can't figure out why the pilot flame is not igniting the main burner? What can happen? Today the column operates on this principle. A spark appears that ignites the wick. Further, the spark supply process stops, the igniter works for a few seconds and goes out. The device gives a spark again, the wick starts to burn, the spark discharge disappears, and after a while the main burner ignites. The ionization sensor appears to be damaged. First you need to inspect it. Naturally, it is better to replace it with a new one, but if it fails, you will have to clean this one with sandpaper. Also clean the burner with a metal brush. After these measures, be sure to check that the wick has a bluish flame, not yellow. In addition, the fire must hit the ionization sensor. The Selena SWH gas flow column was installed and commissioned a year ago. But in winter, a problem is systematically observed, namely, there is not enough gas and besides, the gas is not clean. How can the problem be solved? The adjustment screw is located at the bottom of the unit. With the burner on, try turning it to the left and setting the correct flame height. When summer comes, you can turn it back. If this procedure does not correct the problem, then the pressure in the system is really insufficient. We have been using a gas water heater for about 6 years. Two days ago, the ignition device stopped turning on, and when you try to ignite with matches, the flame can immediately go out at the stage of switching the regulator to the heating position. How to be in this case? I faced the same issue. The specialists explained that the thermocouple is faulty. Tell me about the malfunction of the gas column. When the hot water tap is opened, the unit goes out. Tried cleaning the thermocouple but it doesn't help. We checked the membrane, everything is fine with it, but in any case we changed it to a new one. There is a decrease in the water pressure, though not significantly. What is the problem? It can be assumed that the thrust is unsatisfactory or the thrust sensor is out of order. You should check it out.It happens that in place of the thrust sensor there is a curved tube at the top of the device. The air is supplied through it, which is required for combustion. If the draft is broken, flue gases begin to enter the tube, and not air. Accordingly, there will not be enough oxygen for the burner, which is why it will go out. The pilot burner flame should also be checked. It must fully enclose the thermocouple. When this is not the case, the thermocouple heats up slightly and does not give a ignition signal to the main burner. Recently I began to observe a serious malfunction: the Selena turbocharged column stops during operation. Explain, please, what problems could be? The membrane of the water block may be damaged. It has deformation or wear, for this reason it should be replaced. You can also inspect the EMC valve, as it contains an electromagnetic coil, which may have a malfunction. The coil cannot be repaired, only replacement. Explain, please, on the malfunction of the gas water heater. After a short period of time after switching on, the unit finally extinguishes, and then the ignition device can be ignited exclusively by means of matches. What do i do? Presumably, the draft in the chimney has weakened, as a result of which the reverse draft sensor has worked, and the water heater goes out. You must perform a chimney check. Overheating of the water in the heat exchanger can also occur when the temperature rises to 90C. In this case, the overheating sensor will be triggered, which will extinguish the burner fire. To reduce the water temperature, it is required to reduce the gas on the main burner by means of the regulator. I would like to know why the gas column starts to burn and then goes out? How would you advise to eliminate this breakdown? In the first case, the reason lies in the blockage of the chimney. Presumably, it contains a large mass of soot, and combustion products are not completely removed, as a result of which the draft sensor is triggered. It opens the thermocouple, and the flame of the device is extinguished. Another reason is the increased wind, which is able to extinguish the flame of the apparatus if there is a draft in the room. Accordingly, the protection mechanism will turn on and stop the flow of gas. Strong wind gusts should be avoided. But still, you should not completely restrict the access of fresh air, since the device must be operated with an open window. If there is no fresh air, the draft will be poor and the flame will start to extinguish. The private house has a Selena SWH 20 E2 gas water heater. Explain why she began to heat the water too much? What are the recommended operations to eliminate this malfunction? Too high pressure is a possible cause. Set the regulator to the heating medium heating temperature to the highest flow rate, and the gas regulator must be set to the position of the minimum gas flow to the burner. This method helps to reduce the temperature of the water that comes from the water heater. For what reason can there be a slowdown in ignition, and the gas burner device pops violently? The fire of the ignition mechanism does not reach the main burner, or it is negligible. It is necessary to clean the nozzle and igniter. Then make the setting. Gas water heater malfunction. I try to turn it on, there is a spark, although the ignition does not go on. How can you fix this? Pilot nozzle clogged. You must purge. The ignition electrode is in the wrong position. Adjust it. The presence of air in the gas line. Eliminate air. We installed and connected the Selena geyser. The problem is that the device starts up and then goes out after a couple of seconds. This is especially the case at night, when the equipment has a long rest from work. In addition, if it is constantly heating the water, it will no longer turn off.With long clicks of the microswitch, the water heater ignites and continues to work well for several days. What is this reason? There is no need to click the microswitch, just install a new one, as yours is broken. The actions of the apparatus are approximately the following. A spark pre-occurs, which goes to the igniter. The ionisation signal passes, gas flows to the main burner and a flame appears. If there is no signal that the pilot burner is operating, the main burner will also not start. Your ignition device sends a signal, although the main burner does not start. The ignition has started, but there is no signal, so the gas flow will be stopped. Try cleaning the electrode. A similar unit is in use. What causes the ignition device to go out at the time of ignition? What could be the problem? The thermocouple is inoperative. Replacement required. Coil defective. Install a new one. There was a question about the operation of the Selena water heater. The situation is this: the pilot burner ignites, but the main burner does not function. What to do and how to repair it? The water pressure is lowered. Adjust the required system pressure. For this, we advise you to turn the switch all the way to the right. Diaphragm worn out. Change it. I use a column in a private house. If you stop the flow of water, the burner will not go out. What is the cause of the breakdown? The gas valve flap is clogged. Inspect it. Rinse if required. The movement of the water valve stem when open is impeded. Dismantle components, clean, install new ones if necessary. Check the gas inlet pressure. Adjust if necessary. Change the cylinder pressure reducer. I just can't understand why there is no spark at the moment the device starts up? There was a break in the ignition wires. Connect the wires as required. Failure of the ignition element. It is necessary to inspect this device and change it. Broken ignition electrode. We need a replacement.

NEVA REPAIR

The gas water heater Neva VPG-12E is in operation, after turning on the hot water tap, the column lights up, but the temperature does not rise above 20 degrees. The water pressure is normal, it does not respond to the flame increase regulator, as it was 18-20 degrees, it remains. What could be the problem?

ARISTON

I connected an Ariston Marco Polo Gi7s column. Everything is working. But the device is turned on the second time. That is, you turn on the water, the column starts up, clicks and goes into the E1 error. Then he closed the tap, opened it and it starts up. Powered by a balloon. Is this possible because after her work I turn off the gas?

ELECTROLUX

Malfunction of the Electrolux 275 gas column, you turn on the hot water, everything lights up and works for 5-7 minutes after which a click occurs in it and it goes out together with the igniter. Tell me what is the problem?

_____________________________________________________________

OASIS

Malfunction of the Oasis TUR 20 gas water heater. In the "Summer" mode, the gas and water regulator is at maximum. It goes out by itself when after 5 minutes, when after 30.In the "Winter" mode, with any combination of regulators, it goes out after 30-40 seconds. What can be wrong? Water supply with flexible hoses. Could they be the cause? If so, what to replace?

VECTOR

Tell me I have such a problem: when the water is turned off, the column ignites itself, the temperature rises and does not turn off (I had to remove the batteries), I put the batteries back (I do not turn on the water), it lights up, what should I do?

ASTER

Help me find the reason, the Astra 8910-02 gas water heater, when hot water is on, it goes out from time to time, I cleaned the thermocouple to a shine, the membrane is in good condition, but just in case replaced it with a new one, the water pressure is less than that of cold water, what else note?

BOSCH

I installed and put into operation a Bosch WR 13 gas water heater. I moved the nozzles to liquefied gas, remove the jumper from j6, that is, switched to liquefied gas mode, but the column does not work, who knows what about this? When turned on, the green button lights up for a couple of seconds, and then the red starts blinking and only the fan turns on.

JUNKERS

The Junkers gas water heater began to malfunction. It works for 15-20 minutes and goes out. You turn off and turn on the water, the igniter lights up, and after a few seconds it goes out, and you can do this at least how many times, it does not ignite. A little time passes - it works, and again everything repeats itself. The water pressure is good, the gas pressure too. What could be the reason?

Algorithm of action (step by step instructions)

Unscrew the fasteners from the water unit.

To get to the rubber membrane, you will need to remove half of the assembly, if the element is severely deformed, then the root cause of the problem is in it. The part can be bought at a store that sells spare parts for gas water heaters, but it is better to choose a silicone membrane, which is more durable than a rubber product.

Check the condition of the filter on the water intake, it must be cleaned whenever it becomes clogged. To clean the filter, unscrew the nut, take out the mesh, rinse it; if damaged, the element must be replaced.

Features of using the device

So, in order for the Oasis gas water heater, the instruction manual of which is attached to the product, to work effectively, you need to follow certain rules for using the device:

Use only the type of gas specified in the technical recommendations;
It is necessary to monitor the charge of the batteries on which the device works;
If you want to turn off the device, you must first turn off the water;
If you are going to use the equipment for the first time, you need to take into account that air may be present in the gas supply pipes, so the device may not immediately ignite;
The setting of the degree of water heating must be carried out by turning the handle of the tap or the gas regulator on the body of the device;
If you are going to turn off the device for a long time, you must first turn off the hot water tap, the gas shut-off valve.

The gas column dies out

When a household heater first turns on, but soon fades out, the reason often lies in a malfunction of the bimetallic temperature sensor, which is required to protect the device from overheating. If the temperature sensor is broken, the device may not turn on, and then the development scenarios may be as follows:

The gas burner ignites, the equipment turns on and works properly for some time, but it dies out quickly, after which it will no longer be possible to ignite the heater. It will take 20 or 30 minutes, and only then can the equipment be turned on again, but then the same thing happens.

If the sensor is too sensitive, then we are talking about a factory defect. It is better to call a technician and make warranty repairs, rather than torment yourself trying to get the device to work.

The equipment turns off in a chaotic manner, sometimes it fails to turn on. The insulation on the conductor has worn out, as a result, a short circuit to the body has occurred, then the safety valve is triggered, the column ceases to function normally. And in this case, employees of the service center will help you.

The main causes of the malfunction and their elimination

The designs of all gas water heaters are similar to each other. Why not summarize all the problems and describe the options for solving them? Because each brand has its own weak points. Then there are malfunctions characteristic of specific brands. We analyzed user reviews to collect reliable information for you.

In Oasis water heaters, factory defects are extremely rare.

External and internal factors can cause a breakdown:

Incorrect installation and connection.
Incorrect operation.
Chimney and ventilation blockages.
Problems with internal components: scale, corrosion.

We have described the ways to fix these problems below.

The column does not light up

There can be many reasons, we will help you figure it out. The main thing is to correctly determine the place of failure.

If the device does not ignite at all, no spark is generated, then:

The batteries are dead. Automatic ignition devices are battery operated. For replacement, take quality elements with a good charge. If you find a leak where they were installed, clean all contacts and install new batteries.
Traction problems. For the normal operation of the equipment, there must be a draft in the chimney. If not, inspect the ventilation hole for blockage. This could be a foreign object, soot, or debris from the street. Clean the hole if possible. Make sure that the outside of the chimney outlet is not blocked.

How do you know if there is cravings? Light the spike, bring it to the viewing window of the column. The flame deflects - there is a thrust, it burns evenly - no. You can also lean a piece of paper against the ventilation. In the presence of traction, the sheet will press against the terminal, otherwise it will fall.

The water pressure regulator is set at the minimum level. A small pressure is created in the system to activate the diaphragm and open the gas valve. Set the knob to the maximum value.
Low line pressure. Does a trickle flow when you turn on the tap? Contact the water utility and wait for the supply to be restored. If this happens frequently, it is recommended to install a circulation pump.
The strainer is clogged. The part is located at the entrance to the water unit, retains small debris that enters with the flow of water. It is necessary to disassemble the unit, rinse the filter under running water.
The membrane is stretched. The element is used to start the gas valve. With line pressure, the diaphragm expands, pushes the stem and opens the valve. It wears out over time, so it needs a replacement. You can read about it here: "Water column of the gas column".
Broken microswitch. It cannot be repaired, so a replacement is needed.
Wiring problems. Remove the cover, inspect all wires leading to the control box. If the insulation is broken, replace the loop.
Defective solenoid valve in the gas unit. You need to inspect, check and install a new part.

The flame is lit and extinguished

This happens when the electronic unit does not receive an ignition signal, stops the ignition and shuts off the gas. The reason may be a malfunction of the flame sensor or the formation of carbon deposits on the sensor.

Remedy: Lightly clean the sensor with a fine emery cloth (zero grade). In this case, one should not be too zealous so as not to damage the metal coating. If this procedure fails, the flame sensor needs to be replaced.

The column is leaking

Leaking is a serious malfunction, but you can deal with it yourself.

The stuffing box leaks through the stem. To verify this, remove the shroud and check where the water is coming from.

How to do a DIY repair:

Remove the adjustment knobs by pulling them towards you.
Unscrew the four screws securing the casing.
Disconnect the display wiring.
Remove the batteries from the unit and disassemble it by unscrewing the bolt from the bottom.
Disconnect the water hoses.
Unscrew the bolts of the water valve, remove it.
You got to the stuffing box and its stem. When dismantling the old stem, the gasket may remain inside - this is not a big deal. Simply remove the gasket from the new part and install.
Assembly is carried out upside-down.

A more serious problem is radiator leakage. The new heat exchanger costs almost as much as the new Oasis Turbo model. How to save money? Close the fistulas by soldering. Read more in the article "How to solder a gas water heater".

The easiest way to repair a leak is if a hole has formed on the outside of the tube. Then you can use cold welding. Internal corrosion requires the use of a soldering iron or torch with a temperature of 170 degrees. A rosin or aspirin tablet is suitable as a gumboil.

Before starting work, prepare the radiator:

Drain the pipes.
Dry.
Sand the solder area with fine sandpaper.
Wipe with a degreaser.

You can start repairing. To prevent the fistula from appearing, the thickness of the solder should be 2-3 mm. Examine the node for green spots - these are future fistulas. Better to take care of them right away.

The column goes out after a few minutes

Such a malfunction is often associated with poor traction or overheating.

Remedy: clean the chimney, reduce the water temperature by adjusting the flame and pressure, do not dilute hot water with a mixer.

Clogged heat exchanger

How to understand that the radiator is clogged:

Long-term heating of water.
The stream is not hot, but warm.
Pieces of scale come out together with water.

Gas smell is felt during heater operation

We turned on the column and felt a sharp and unpleasant smell of gas, immediately turn off the device and turn off the gas supply with a tap, ventilate the room and call the gas service.

Taking any action on your own is dangerous, you do not have the appropriate qualifications for this.

The gas column lights up and goes out

Gas water heater - the device is quite reliable and, with proper operation and proper care, will last a long time. However, sooner or later everything fails and requires repair. Faults in gas appliances must be trusted in the reliable hands of professionals. However, today we will consider typical examples of speaker breakdowns that are not associated with a device defect, and we will learn how to determine this or that breakdown even before the arrival of specialists. The first reason for the flame to go out when the gas column is ignited may be the lack of draft in the ventilation duct.

The situation when the gas column does not light up is, of course, unpleasant, but it's too early to panic.
