Repair of Astra brand geyser
Repair of the Astra geyser begins with shutting off the gas. The column does not need to be removed. The front part can be dismantled using a screwdriver, but first you need to unscrew the bolts located on the sides. The first thing you need to check is the economizer; it is located behind the electrode. Removing the latter will be quite difficult. It is fixed with 4 bolts. You should not touch the heat exchanger.
When you repair individual components, it is important not to touch the fitting; it is used to measure pressure. If this part is damaged, the head will have to be replaced. In order to remove the economizer, you only need to unscrew the two side bolts. The consumer may well carry out the repairs with his own hands. The Astra geyser has contacts in its design that often become dirty. If they become unusable, they need to be replaced. If the economizer does not work after replacement, then it will also have to be changed. These faults are among the main ones for Astra speakers.
If you are faced with a problem when the Astra gas water heater does not light up, this may indicate a lack of draft in the ventilation passage. You can check the traction very simply. The gas water heater is turned off, and a burning match should be brought to the chimney outlet. If the flame is carried into the chimney, then everything is in order - you can connect the column. Otherwise, the chimney should be cleaned. However, it is better to entrust this matter to a special master.
The Astra geyser, the malfunctions of which you should consider when operating this equipment, sometimes goes out immediately after ignition. In this case, you should adjust the supply of cold water to the column. Do not try to dilute hot and cold water, as this may cause the flame to die out.
If the column does not light up
The most common problem that happens with a gas water heater is that the heater does not light up. The cause of the problem may be a lack of traction. Before turning on the column, you need to check the draft in the ventilation hole - light a match and bring it to the chimney outlet. If everything is in order, then the flame seems to be drawn into the hole - there is draft, and you can turn on the device. If the flame does not stop, the chimney needs to be cleaned. You can do this yourself, but if you lack the skills, it is better to entrust it to a specialist.
Another common malfunction that occurs with gas-powered water heaters is extinguishing after ignition. If the wick goes out, you need to adjust the cold water supply.
