Electric gas water heaters are popular because they are easy to use. The ignition is triggered automatically when the mixer is opened. The current to create a spark is produced by batteries. What if the geyser batteries do not work? How to choose and change them with your own hands? For stable operation, it is important to choose a quality replacement. We describe the features of the choice and all stages of the repair.
Why do batteries run out or deteriorate quickly?
The principle of operation of automatic water heaters is as follows: when the mixer is opened, the batteries are activated, the current is sent to the control module. The latter gives a signal to the spark plug, which produces a spark in the ignition unit. Under pressure, the valve opens and starts the gas into the burner. This is the ignition.
When the batteries are dead, the spark is unstable or the column does not turn on at all. Some models have the function of reporting the discharge of elements by flashing the LED. Why is there a quick discharge?
High humidity.This happens when installing the device in the bathroom: steam and moisture settle on the parts, interfering with normal ignition. For this reason, the contacts of the power supply are oxidized and corrode. Sweep. The room should be often ventilated, install powerful ventilation.
The ionization sensor is not working properly.This sensor is responsible for the presence of flame in the burner. If it has shifted far to the side, a spark is generated for a long time and consumes charge energy. Check and correct the location of the sensor.
Perhaps he was clogged. Soot can settle on the part, then it loses sensitivity. Clean the sensor, restore it to work.
The ignition electrode has shifted.As a rule, when gas enters, the spark should immediately ignite and turn into a flame. If this does not happen for a long time, try moving the electrode closer to the burner.
Problems with the control unit.Batteries power the electronic module. If there is a problem in it, then a lot of electricity can be spent on work. Remove the cover, inspect the unit. Disconnect the wires leading to it, open and check all the details at the time of burning. If no visual defects are found, call the repair wizard.
Poor quality batteries.The speakers use “D” type batteries with a voltage of 1.5 volts. Some users save on replacement, buy cheap items. As a result, they sit down after two to three weeks, the ignition does not work stably.
What kind of batteries are needed? It is advisable to choose according to the manufacturer's recommendations. Pay attention to the size of the products, the level of charge. Buy alkaline type LR20. The best companies: Duracell (Durasell), Energizer (Energizer).
Installation of new parts
Here is the sequence of replacement steps for Neva speakers. The work is carried out almost the same for all brands of technology.
Turn off the gas and water supply first. You will find a plastic block at the bottom of the case. Open its cover by turning the knob counterclockwise.
However, not all models are so simple. There are different types of boxes:
- On latches. When you open the lid, you will find vertically placed elements. They are held by a L-shaped latch. Move them, replace. Then close the lid and turn the knob.
- Retractable box. This is found in the Neva Transit model. Below you can see only the outer wall of the box, the rest is hidden in the case. To dismantle, click on the wall until it clicks - the contents will slide into your hand. Make a replacement, put the unit back. It is important not to confuse the installation side and polarity.
How to light a column without batteries
How can I replace the batteries? For example, a battery. Choose the same size product. The price of batteries is much higher, in addition, you will have to buy a charger. But, as soon as the products are discharged, you can charge them, and not buy new ones.
You can organize power from the network. To do this, you need to connect the column through the power supply, which corresponds to the characteristics of the box of the device. It should be borne in mind that in this case, when the power is cut off, there will also be no hot water. But if the work is done correctly, it will be possible to use batteries alternately.
- What parameters to focus on? Two elements give a charge of 3 volts, the equipment is connected to a 220 volt network. So, you need a device that gives 3 volts at the output and 220 at the input. The current strength will be 550 MPa.
- Prepare two male-to-female connectors.
- Remove the lining from the column.
- Disconnect the wiring from the power box. You can take pictures of the connectors or mark them with a marker.
- Cut off the plug from the purchased unit.
- By soldering, attach the dad-mom connectors to this place.
- A multimeter will help determine the correct polarity. Set it to voltage measurement mode. Positive readings indicate that the polarity of the wires is the same.
- Connect the power wires to the speaker. Plug in.
- It is recommended to turn off the device at night.
For reliability, experts advise installing a stabilizer. It will protect the equipment from voltage surges. Wiring diagram:
To switch the power back to the batteries, rearrange the terminals during a power outage.
