The water heater is not warming water

Damaged electrical wiring, a faulty heater may cause a malfunction of the boiler. To find out why it does not work you need to carefully inspect it.
Heater does not work for the following reasons: on the surface has accumulated a lot of scale, is not included thermal button; heater can not heat the water due to a faulty pressure relief valve. It is necessary to find out all the reasons why the water heater does not heat water, but the light is on at the same time or is not illuminated.

Common causes of failure

Often the cause of a malfunction of the heating element may be a non-working electronic module. Do not try to make repairs on their own. Damage to the machine may be caused by an alarm is fairing. Due to the deposition of scale on the PETN, fairings are starting to include in any order.

Check the water heater can work with the help of an incandescent lamp. It must be connected to the heating element. Once connected, the electrical circuit must be connected to a power source. Heater functions correctly if the lamp is illuminated. Another method is the use of the meter. On it is necessary to join the resistance measurement mode, connected to TENu. In the closed circuit, the indicator will show zero. If the circuit has a break indication will be infinite.

The 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 is off.
failure causes may include:

• broken heater;
• on the heating element there are many deposits as scale layer;
• It does not work the safety valve;
• It does not operate the electronic board.

IMPORTANT! ThOba solve these problems need to be drained, disassembled boiler. Check on it with a multimeter, voltage tester, the tester is operating correctly. If the indicators point to an incorrect operation of its elements, replace them or eliminate the causes of their failure.

The boiler does not heat up, but the lamp is lit

The causes of this problem are different breakdown.

The handle is in the "minimum" mode, for this reason, the tank is not warmed up to the desired temperature. To solve this fault can be unfolded Clockwise movement arrows.
I switch on the unit. To get out of this situation, will the inclusion of the thermal protection button. It is located on different models in different places.
Do not close the valve. You must make a hand to the riser. If it is warm to the touch, and comes out of the tap cold water, then, the valve does not work. It is necessary to cut or buy and exchanged for a new one.
Long heated. It is not necessary to drain the water directly, it would be correct to wait until it warms up.

Solutions to the problem of failure of PETN

Purification using one liter of water, 50 grams of citric acid. The device is dipped into the preparation of these substances dissolved in the two days. After that, he pulled out and clean off the scum. Substitution of PETN in different models of the same boiler.
To make it you need to:

• shut off valve;
• clean the heater;
• for security reasons you need to disconnect the boiler;
• remove the protective cover;
• special screwdriver to see if voltage is present;
• make photo connection diagram;
• remove the heater from fastenings (enclose the cloth if necessary);
• wait when the fastening place completely dry (no contacts should have a moisture);
• look at the anode, to determine whether he is OK;
• check the seal of the rubber for wear;
• after the heater has been replaced, install all the parts back.

Doing all these activities, you must make sure that there are no leaks. The air in the boiler be released, and then turn the unit into the wall socket.

Why is the water heater does not heat the water up to the maximum

One of the most common reasons for which the boiler is functioning correctly, a malfunction of PETN. This problem is related to the ancient models. Typically, the life of the heating element is equal to four years. Over time, it formed sediments. They inhibit the normal operation of the device.

If no action is taken to his replacement, cleaning, it can lead to failure of the heating element. The heater may not operate properly due to failure of the thermostat, and therefore does not heat the hot water.
