Like any other electrical appliance, the boiler cannot be operated 24/7 without at least monthly maintenance, not to mention the replacement of "depleted" components. If you think that you can buy equipment once and never look after it again, “maybe everything will be fine”, then you are deeply mistaken. Most people misuse even the water heater, so it fails.
In our article, we will provide complete instructions on how to repair a boiler with your own hands without the outside help of an expensive craftsman or a klutzy neighbor. Learning how to do everything yourself is not so difficult, and we will prove it to you!

The main places of the water heater that require repair most often
Even if you are not installing the heating device, but the selling company or acquaintances, study the technical data sheet and instructions in detail - this is the minimum that is required of you. These documents provide a comprehensive description of which elements need special care, as well as tips on how to fix the water heater on your own.
A large number of malfunctions are associated primarily with the leakage of the water tank. In order to quickly respond to a problem that has arisen and quickly repair a water storage heater with your own hands, you must first find a leak.
But not in 100% of cases it can be said that the tank has broken, because other problems may occur:
- protective pads are depleted or completely unusable;
- heating element malfunctions;
- temperature sensors or thermostat do not work as they used to, or refuse to work at all.
To protect the water heating element and reduce the number of breakdowns, a safety valve is built into the housing even at the production stage.
There are also situations when the boiler does not work due to a malfunction of the cold and hot water supply systems. Most often this happens when someone did not have enough knowledge or skills to make the correct installation. Therefore, we strongly recommend that you contact familiar specialists for installation, or at least control the sealing of all connections (this can be checked at the points of fastening of taps, bolts etc. - there must be a winding from the FUM tape).
In more expensive water heating systems, several heating sensors are installed at once. The first is responsible for the temperature of the water in the tank, the second - for the safety of the first, the third - for the degree of operation of the heating element.
Of course, all boilers are produced by different manufacturers, and models of the same production may differ in functionality and components. The similarity is in one thing - the principle of operation of the part is identical, and it can be replaced with a similar one in size. Everything is done very simply and with your own hands.
Recommendation: if you want your device to work for more than 10 years "faithfully", do not use it with defective elements. Repairing it is not difficult, and sometimes it generally takes no more than 5 minutes. And how to do it - read on.
How to repair a water heater - clean the tank

The manufacturer often writes in the instructions that it is necessary to carry out regular maintenance of the devices. And we, as always, either lose sight of the moment, or do not read the documentation of the technique at all.
In order for your boiler to work without problems and complaints, it is advisable to clean the tank at least once a year.
If the heater is not located at home, but in an office or public place (areas of increased load), then it is better to clean it every 6 months.
If you are afraid to disassemble the device yourself, contact the certified institution that issued the warranty card. You will receive a free service. If the deadline has expired, we will study on our own, because it is not so difficult.
Boiler Maintenance Procedure:
- Disconnect the machine from the power supply and turn off the taps for the water supply.
- Drain all the water from the tank and close the outlet.
- We remove the car and unscrew the fixing bolts. They are immediately visible on the body.
- We look at the degree of pollution and try to clean all visible components.
- We replace the protective gasket and the magnesium anode (you can immediately ask the store what it is, and then find them in the case and quickly change them).
- We twist the cover, put it in place and connect all communications.
One of the most common causes of failure is electrical corrosion. Over time, it corrodes the walls of the tank, which results in leaks. To avoid this, a magnesium anode is installed, which must be replaced regularly.
How to repair a water heater with your own hands: a solution for the most common causes
The surface of the tank itself consists of several plates: a tank, a heater and an outer shell. If corrosion has already begun inside, then it will affect other layers of the boiler.
We look at the tank
Another cause of failure is mechanical damage to the inside. This can happen due to improper or careless installation by the master. How to repair the boiler in this case? Almost nothing. Even soldering scratches or holes will shortly extend the life of your equipment. Option one is a complete system replacement.
For us, one regularity is important: if the device is leaking, then the problem is definitely in the reservoir. If the breakdown can be seen immediately, on the surface, we replace the elements of the breakdown area. If the leak is inside, repeat the steps described in the previous section.
Heater
A large number of problems arise due to the heating element. If barely warm water flows from the tap, then it does not work well. How to fix the boiler in such a situation? We go through several stages. The first is to check the power supply. It will require a multimeter (tester).
Follow these steps:
- We set up the tester for a range of 220-250 volts.
- We fix the values \u200b\u200bwith clamps on the terminals where the power supply from the boiler passes.
- If there is no voltage, then the water heater does not work.
If, nevertheless, current is supplied to the network, then you need to remove the heater cover and check all open contacts with a tester. If the heating element does not work properly or does not react at all, we buy a new one.
Thermostat
The failure of this part can also affect the operation of the heating elements. It is checked by two options: a multimeter or a lighter. Let's take a look at the last option:
- We disassemble the thermostat.
- Next, we find the copper contact and heat it with a lighter.
- Before that, press the button (it will be clearly visible on the thermostat panel). If the button clicks after heating, then the part is working.
- No reaction - we buy a new part and insert it in place of the unusable one.
These are the main points that affect the quality of the water heating system. There is another solution - write to us in the comments!
