The boiler allows you to use hot water daily without regard to communal services. However, the equipment is not insured against breakdowns. What to do if the water heater does not heat? You need to look for signs of a problem and find the reasons. Many devices are equipped with a self-diagnosis system, which facilitates the task by displaying an error code on the display. To fix the problem, read below.
Why did the electric boiler stop heating water
Two symptoms of a malfunction:
- The indicator on the panel is on.
- The light on the panel does not light.
If the equipment heats the water badly, but the lights are oncheck the main tap. When it breaks down, the equipment can work normally, only hot water goes to the neighbors.
You may have forgotten to close the valve. Touch the riser: if it is warm and the tap has cold water, it’s the valve. Block it or replace it with a new one.
Does technology heat water for a long time? Make sure you do not drain the contents until it reaches the right temperature. How much is the boiler heated? Depending on the volume, from 2 to 4 hours. It is also important what voltage is applied to the device.
Regardless of the brand of the boiler, Ariston or Termex, scale could have caused poor heating.
If a technical inspection is not carried out in a timely manner, limescale strikes the walls of the tank, all the details, including the heater. The thicker the “crust” becomes, the more difficult it is for the element to transfer heat. Gradually, the heating time increases or the heater burns out.
To prevent this from happening, read the publication How to Clean a Water Heater and follow the instructions.
Does the boiler not hold the temperature? The reason may be the depressurization of the tank. It consists of two parts, isolation lies between them. Inspection and repair of the tank is needed.
Indication off, the appliance does not heat water. What's the matter? It is necessary to check what voltage is supplied to the device. Press the plug more firmly to the outlet; it may have come off. Also check the network cable - do this:
- Take a multimeter or indicator screwdriver.
- Attach a dipstick or screwdriver in the “phase”. If there is a signal, the cable is working. Moreover, on the “zero” and “earth” he should be absent.
Then, check the outlet for proper operation. To do this, connect another device to it. Has he earned? The outlet is working.
Another option: the voltage in the outlet is not enough for the normal operation of the boiler. Check the RCD machine, it may have been knocked out.
After checking it turned out that everything is normal with the network? Then the reason is in the technique.
Self-diagnosis and repair
First of all, the thermostat is checked, which regulates the temperature. Attach the tester probes to its terminals and check if voltage is applied to them. Are the numbers reflected on the screen? So the voltage comes in. Turn on the thermal protection button. If the temperature is exceeded by more than 95 degrees, a fuse is activated and the heating is turned off.
After turning on thermal protection, the part did not work? Then you need to replace the thermostat.
Damage to the heater also leads to similar consequences. On average, it serves up to 4 years, but if you do not change the magnesium anode and do not perform cleaning, the operating time is reduced. How to diagnose a heating element, we described in the article “Replacement of a heating element”.
The malfunction of the heating element is affected not only by scale, but also by switching on the boiler without water.
Having problems with a flow heating element? Again, you need to check the power, because this type of equipment is more powerful. If the power consumption is more than 5 kW, be sure to install a circuit breaker at 30 A, with a consumption of 7 kW - at 40 A. If these rules are not followed, the element will not last long.
A malfunction could have occurred if the pressure sensor was not triggered timely. The pressure in the system is too high, the sensor does not work, the heater burns out.
What causes the pressure sensor to break? It is equipped with a membrane. During the water supply, it stretches and starts the sensor. When it is stretched or damaged, the part does not work in a timely manner. It is better to install a silicone membrane as a replacement.
When buying a groover, pay attention that the element is in a protective flask. In contact with water, salts quickly corrode its surface.
Now you know what to do in case of problems with heating. To avoid them, it is important to properly install the equipment and operate according to the instructions.
