The water heater does not heat water, but the indicator is on

Damaged wiring, faulty heater may lead to malfunction of the boiler. To find out why it does not function, you need to carefully examine it.
The heater does not work for the following reasons: a lot of scale has accumulated on its surface, the thermal protection button does not turn on; the heater may not warm up the water due to a faulty safety valve. It is necessary to find out all the reasons why the water heater does not heat water, but the indicator is on or off.

Common Causes of Breakage

Often the cause of the malfunctioning of the heating element may be an inoperative electronic module. Do not try to repair it yourself. Damage to the unit may be triggered by emergency radomes. Due to scale deposits on the heater, the fairings begin to turn on in random order.

You can check the operation of the water heater using an incandescent lamp. It must be connected to the heating element. After connecting, the electrical circuit must be connected to a power source. TEN functions correctly if the lamp is lit. Another way is to use a multimeter. On it, you need to turn on the resistance measurement mode, connect to the heater. With a closed circuit, the indicator will show zero. If the chain has a break, the indicator will be infinity.

The water heater does not heat water, but the lamp does not light up

There are situations in which the heater does not heat water to the desired temperature, the lamp does not light.
The causes of failure can be:

• idle heater;
• a lot of deposits appeared in the form of a scale layer on the heating element;
• the safety valve does not work;
• the electronic board does not work.

IMPORTANT! ThTo solve these problems, it is required to drain the water, disassemble the boiler. Check on it with a multimeter, voltage indicator, tester for proper operation. If indicators indicate incorrect operation of its elements, replace them or eliminate the causes of their failure.

The boiler does not heat, but the lamp is on

The causes of this problem are different breakdowns.

The handle is in the "minimum" mode, for this reason the tank does not warm up to the required temperature. Such a malfunction can be solved by turning the knob clockwise.
The thermostat has turned on. To get out of this situation, the inclusion of a thermal protection button will help. She is on different models in different places.
The valve is not blocked. Place your palm on the riser. If it feels warm to the touch and cold water comes from the tap, the valve does not work. It needs to be blocked or bought and exchanged for a new one.
Heats up for a long time. Do not drain the water immediately, it will be correct to wait until it heats up.

Options for solving the problem of the heater failure

Purification with one liter of water, 50 grams of citric acid. The device is immersed in a solution prepared from these substances for two days. After that, they pull it out and clean off the scale. Replacing the heater on different models of boilers is the same.
To produce it you need:

• Close the tap;
• clean the heater;
• for safety reasons, the boiler must be switched off;
• remove the protective cover;
• with a special screwdriver to find out if there is a voltage;
• take a photo of the connection diagram;
• remove the heater from the mounts (if necessary, put a rag);
• wait until the mount is completely dry (the contacts should not have moisture);
• look at the anode, find out if it is working;
• check rubber gasket for wear;
• after the heater has been replaced, install all parts back.

Having done all these actions, you need to make sure that there are no leaks. The air in the boiler must be released, and then plug the unit into a power outlet.

Why does the water heater not maximize water

One of the common reasons why the boiler does not function correctly is the malfunction of the heater. This problem is characteristic of ancient models. Typically, the life of a heating element is four years. Over time, deposits form on it. They interfere with the normal operation of the device.

If you do not take any measures to replace it, clean it, it can lead to failure of the heater. The heater may not work properly due to a thermostat breakdown and therefore do not heat hot water.
