Electric gas water heaters are popular because they are easy to use. Ignition works automatically when the mixer is opened. Batteries generate electricity to create a spark. What to do if the batteries for the geyser 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 will describe the features of the choice and all the stages of repair.
Why Batteries Drain or Die Quickly
The principle of operation of automatic water heaters is as follows: when the faucet is opened, batteries are triggered and current is sent to the control module. The latter gives a signal to the spark plug, which generates a spark in the ignition unit. Under pressure, the valve opens and releases gas into the burner. This is how ignition happens.
When the batteries are dead, the spark is unstable or the column does not turn on at all. In some models, the function of reporting the discharge of elements by blinking the LED is implemented. Why is there a fast discharge?
High humidity. This happens when the device is installed 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 corroded. Do a cleanup. The room needs to be ventilated frequently, to install powerful ventilation.
The ionization sensor is not working properly. This sensor is responsible for the presence of a flame in the burner. If it has shifted far to the side, the spark is generated for a long time and consumes the energy of the charge. Check and correct the location of the sensor.
Perhaps he got pissed off. Soot can settle on the part, then it loses sensitivity. Clean the sensor, restore its operation.
The ignition electrode has moved. 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 block. Disconnect the wires leading to it, open and check all the details at the time of burning. If visual defects are not found, you need to call the repairman.
Poor quality batteries. The speakers use 1,5 volt “D” type batteries. Some users save on replacement, buy cheap items. As a result, they sit down in two to three weeks, the ignition does not work stably.
What batteries are needed? It is advisable to choose according to the manufacturer’s recommendations. Pay attention to the size of products, charge level. Buy alkaline type LR20. The best firms: Duracell (Dyuracell), Energizer (Energizer).
Installing new parts
Here is a sequence of steps for replacing the columns of the company “Neva”. The work is carried out almost the same for all brands of equipment.
Turn off the gas and water supply first. You will find a plastic block at the bottom of the case. Open its lid by turning the handle counterclockwise.
However, not all models are so simple. There are different types of boxes:
- On snaps. When you open the lid, you will find vertically placed elements. They are held by an L-shaped latch. Move them aside, replace them. Then close the lid and turn the knob.
- Retractable box. This is found in the Neva Transit model. Only the outer wall of the box is visible from below, the rest is hidden in the case. To dismantle, press the wall until it clicks – the contents will slide out into your hand. Make a replacement, put the block back. It is important not to confuse the installation side and polarity.
How to light a column without batteries
What can replace batteries? For example, a battery. Choose the same size product. The price of batteries is much higher, besides, 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 supply from the network. To do this, you need to connect the column through a power supply that matches the characteristics of the device box. It should be borne in mind that in this case, when the electricity is turned off, there will also be no hot water. But if the work is done correctly, it will be possible to alternately use batteries.
- 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-female connectors.
- Remove the lining from the column.
- Disconnect the wiring from the power box. You can take a picture of the connectors or mark them with a marker.
- Cut off the plug from the purchased unit.
- Attach the male-female connectors to this place by soldering.
- A multimeter will help determine the correct polarity. Set it to voltage measurement mode. Positive readings indicate wire polarity match.
- 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 power surges. Wiring diagram:
To switch power back to batteries, reverse the terminals when there is a power outage.
