The modern market is constantly replenished with new units that are able to satisfy consumer demands. Modern equipment only remotely resembles its bulky predecessors.
Overview of repair options
The devices are equipped with modern automation, they are protected by multi-stage systems and provide increased safety during operation.
One of the most popular is the Neva 4511 geyser, you can do this equipment repair yourself if you read the information below. But experts do not recommend undertaking such work on their own, this is especially true for those people who are not too well versed in such a technique. It is not recommended to do this if the warranty period has not yet expired, because self-repair will void the manufacturer’s obligations. But if the device was purchased a long time ago, then it is worth considering that its design is simple, so any home master will be able to cope with the repair.
Refusal from ignition
The Neva 4511 geyser, the do-it-yourself repair you can do if you refuse to ignite, is a budget and fairly simple model. Quite often, the aforementioned problem can be caused by the fact that the ventilation system suffers due to lack of traction. If this is the case, then you can eliminate the problem by cleaning the channel. If the batteries run out, then a problem may arise with the power supply, this issue is solved by simply replacing it. The gas column "Neva 4511", a review of the failures of which is mentioned in the article, may encounter a refusal to ignite due to the low pressure of water in the system. In this case, the consumer can rinse the filters, as well as clean the device from combustion products. If this approach did not solve the problem, then you should contact the utility with the question of low pressure. If the Neva 4511 geyser does not light up, you can do it yourself by repairing it by adjusting the temperature of the coolant. This solution is relevant if the balance between hot and cold water is incorrect.
Turn on the foreign clap column
The most common cause of this problem is clogging of the ventilation; it may happen that the supply batteries expire or the fuel supply is too intense. Sometimes characteristic pops occur when the nozzle is clogged. In any of these cases, you need to contact a specialist. The only exceptions are replacing the batteries or cleaning the ventilation ducts.
The problem of inefficient heating of water
If a Neva 4511 geyser is installed in your house, you can carry out DIY repair of this equipment. This also applies to the case when the water is not heated as efficiently as required. If the equipment turns on, but the water temperature does not reach the required level, then the equipment simply may not meet the consumer's power requirements. The second assumption is the clogging of the column. In this case, the equipment loses performance. To solve the problem of inefficient heating of water, you can adjust the coolant supply tap or resort to the help of a service center specialist, he will be able to clean the equipment.
Temperature sensor malfunction problem
The gas column "Neva 4511" (automatic) is protected by a multi-stage system, but even so it happens that the column does not ignite. The culprit is the bimetallic temperature sensor, it is designed to protect equipment from overheating. The malfunction usually manifests itself in the fact that the burner goes out, and the column itself works for a certain time, but then stops, and attempts to ignite do not allow to achieve the result. After 20 minutes, the column can be turned on again, the burner will light up, but after the same period of time it will go out again. This may be due to the sensitivity of the equipment. This warranty case, in addition, the problem only occurs in summer or winter, it occurs at too low or too high temperatures, when the windows in the kitchen are closed. In these cases, the temperature in the room is elevated, the equipment does not cool. If you have a Neva 4511 gas column installed, a malfunction in the sensors can also be expressed by a chaotic shutdown of the device. Sometimes it does not light up at all. Behavior may indicate wear on the sensor conductor insulation. A short to the body causes the safety valve to trip. In this case, calling the gas workers is useless, since the problem is not related to the gas part. Doing it yourself is also not possible, so it is best to contact a service center.
Membrane replacement
Before replacing the membrane, turn off the equipment, shut off cold water and gas. One of the hot water taps opens, which will relieve pressure in the pipes. At the next stage, the column cover is removed, and after that - the fixing screws that are under the decorative overlays. The master should remove the water regulator, for this, the motor nuts are unscrewed. Now you can begin the procedure for replacing the membrane. When a Neva 4511 geyser is being repaired with its own hands, it is important to consider that the element to be replaced must not be installed upside down. It is important not to block the bypass. Next, you can assemble the gas column, acting in the reverse order. It is important to put all the gaskets in place, so take the step very carefully, but if you have experience, then these manipulations will take no more than 15 minutes.
