Thanks to the boiler, a person has the opportunity to use hot water, regardless of utilities. However, absolutely any technique can break. What actions should be taken if the boiler is bad or does not heat water at all? You should pay attention to the signs and find out the causes of the breakdown. Some technology has a self-diagnosis - a system that displays an error code on the screen.
Boiler
Possible signs and causes
There are two signs by which faults can be identified:
- The panel light is on.
- The panel light does not light.
If the indicator is on, but the boiler is still bad or does not perform water heating at all, it is necessary to check the main channel. If the main channel breaks, then the water heater may function normally, however, hot water will go to your neighbors.

Maybe they forgot to shut off the valve. To determine this, it is enough to touch the riser. If the riser is warm and cold water flows from the tap, then this is the problem. Close the valve or replace it.
What to do if water heating is slow? First you need to make sure that the contents do not merge before the desired temperature is reached. The time for heating the water in the boiler is different - it depends on the volume. It varies from two to four hours. Time also depends on another factor - stress.
Attention! Limescale can also cause poor heating. It can form in water heaters of absolutely any manufacturer (Ariston, Termex, and so on).
If the technical inspection was not carried out on time, then the raid begins to hit the walls of the tank, other parts, for example, a tubular electric heater. As the thickness of the “peel” increases, the element will transfer heat worse. Consequently, the heating time will also become longer, in the worst case, the tubular electric heater will burn.
Scale on the heater
But what if the water heater does not maintain the temperature? In this case, the cause may be depressurization of the tank. The tank has two parts, between which the insulation is located. For this, inspection and repair are carried out.
The next sign is that the light is on, but the device has stopped heating water. To resolve this problem, a voltage check must be performed. It may be that the plug has moved away from the outlet, it must be pressed tightly. It is important to check the network cable. You need to do this like this:
- Use a multimeter or indicator screwdriver.
- Next, attach a screwdriver in the "phase". If the cable works, a signal should be present. At "zero" it should not be.
The outlet also needs to be checked. To do this, you need to connect another device.
Self-diagnosis and repair
First you need to check the thermostat, which carries out the temperature control. Then you need to attach the tester probes to the contacts. Make sure the probes are energized. Then you should turn on the thermal protection button. When the temperature rises above 95 degrees, a fuse is triggered and the heating turns off.
Tester for diagnosing boiler malfunction
Important! If thermal protection was turned on, but the element did not work, then the thermostat must be replaced with a new one.
This happens if the tubular heater breaks.

The life of this element is four years. This period is significantly reduced if you do not replace the magnesium anode and do not perform cleaning work.
If there are problems with the flow-through tubular electric heater, a power check must be performed. If the power exceeds 5000 W, then you need to install a circuit breaker at 0.03 kA. If it consumes 7000 W, then the automatic machine is installed at 40 A. If these rules are not followed, the life of this component will be short.
Important! Failure could happen when the pressure sensor did not work out of time. The tubular electric heater burns out if the sensor does not work when the pressure in the system is high.
What causes the pressure sensor to break? The pressure sensor has a membrane. When water is supplied, the membrane at this moment stretches and the sensor starts. If the membrane is damaged, the element does not work immediately, with a delay. In this situation, the membrane should be replaced with silicone material.
When you purchase a groove, you need to pay attention to the fact that the component is sold in a protective flask. When contact with water occurs, salts instantly corrode the surface.
Observing the above rules, you can solve all the problems with the water heater. To avoid problems, the installation must be carried out correctly, and the equipment should be used according to the instructions.
So to summarize. If the panel indicator does not light on the water heater, then this indicates the following:
- The problem may be in the wire, in the machines. To resolve this problem, you should use the services of an electrician.
- A machine, cable or plug may contain a problem. To eliminate this problem, you need to repair the failed node.
- Untimely activation of thermal protection. To do this, clean the water heater.
- The problem is with the operation of the thermostat. To eliminate this problem, replace the old thermostat with a new one or repair it.
You can contact the service center in your city, which will diagnose and repair your boiler. Experienced craftsmen will cope with this task.
So, now the problems with heating do not seem so big. In order to avoid these troubles, it is necessary to carry out the correct installation of equipment and subsequently, according to the instructions, operate it. The boiler is not a complex device, but it is important to use the instructions for repairs. Often if water heater does not heat water, the problem is the heating element.
