Thermex water heater leaks in the lower plastic cover

What tools will be needed if the boiler is leaking

It's good if you have all this at home. If not, you can buy, most likely, they will come in handy more than once. But today, even in the house management, you can rent many tools, which is also very convenient.

To eliminate a boiler leak, it is necessary to prepare tools for work

So, to eliminate the leak, you need:

• Adjustable wrench (larger than the largest nut in the boiler);
• Tubular wrench set;
• Electronic tester;
• Socket wrenches;
• Rubber hose to drain the water from the tank;
• Knife;
• Screwdriver.

If a full-fledged repair is required, then some minimal knowledge of how a water heater is arranged may not be enough. That is, to figure out why the boiler is leaking, you will figure it out, but you will not master the repair. In this case, you need to rely on specialists.

What to do first

If the unit leaks, it should be immediately disconnected from the electrical network, after which a visual inspection of the entire device should be carried out to determine the location of the leak. In the case when leakage occurs on the side or on top of the device, this indicates the formation of a hole on the body.

Important! The appearance of water leaks indicates an internal malfunction of the product that requires urgent attention, otherwise, in the worst case, you will have to purchase a new device.

Regardless of the cause of the leak, the device must be dismantled.: drain the liquid, remove from the fasteners, disassemble according to the instructions to establish the cause of the breakdown.

What tools will be needed

You can dismantle the equipment using the following tools:

• an adjustable wrench of a suitable size for detaching a large nut;
• specialized multimeter, tester;
• screwdriver;
• knife;
• set of tubular keys;
• rubber tube to drain the water in the working process.

Why does the boiler flow from the bottom or from the top

When you see that the boiler is leaking, disconnect it from the network. Then carefully inspect the device - determine the location and possible cause of the leak. If the boiler flows from above, then there can be only one reason: a hole has definitely formed in the tank.

A boiler can leak for several reasons.

Why can holes appear in the tank:

• Manufacturing defects are not excluded;
• The device has been used for a long time, no preventive work and inspections have been carried out;
• The tank does not have a magnesium rod;
• The water from the pipeline is not of the highest quality;
• The heater tank was not grounded.

Whatever it is, the boiler will have to be repaired. If water flowed out from under the plastic cover, then the reason is serious - perhaps the boiler has broken down completely. If the tightness of the tank is broken, water flows from under the plugs, it moves along the water drainage hoses. The water heater needs to be replaced. Most often, the heating element "flies" - the very element that heats the water. It needs to be constantly descaled, then it will serve for a long time. In a word, everything is like in a washing machine, according to the same principle.

Is it possible to fix a leaking boiler

As soon as the buyer has purchased a boiler, he must know that sooner or later, it will certainly flow, like any other metal vessel. You need to be prepared for this and know that any heater can be repaired, except for the dilapidated ones that have worked out their service life. It is simply impractical to repair this category, they are replaced with new models. If the boiler is leaking, experts will tell you what to do.

Regardless of the reasons why the boiler is leaking, you will need to perform a number of preliminary work that any home master can handle.

To complete the repair, you will need the following tools and materials:

• adjustable wrench;
• electric multimeter;
• screwdrivers and tool knife;
• heads;
• drainage hoses.

The sequence of actions when the hot water boiler flows:

1. Disconnect from voltage.
2. Inspection to determine the location of the leak.

What to do: drip water heater Termeks

It all depends, of course, on the boiler model. These or those have typical leakage reasons. If, for example, one Termeks has a dry type heating element, then a frequent cause of leakage in this case is damage to the bulb covering the heating element. Usually, in this situation, the flange with the flask is removed, and it is checked for fistulas. Fistulas can be sealed, or covered with cold welding. But the one that can withstand the temperature of the water.

There may also be a problem with the gasket on the flange:

• If the rubber gasket has collapsed, water will drip from below;
• To replace the gasket, you need to disconnect the device from the network, drain the water, remove the protective cover, disconnect all wires;
• Then the nuts are unscrewed around the circumference, the flange itself is removed;
• The gasket is easy to see - if it is deformed or torn, you will have to buy a new one (when buying, take an old one that is out of order);
• After replacement, you need to fill the tank with water, check for fistulas.

The Termex water heater may leak due to damage to the bulb

If one of the pipe joints begins to leak, it will become noticeable from the leaks on the pipes. The connection should be untwisted, the old fum tape is removed, a new one is wound. Then you turn on the water, check the knot again. But if a leaking tank formed as a problem, the repair is not so simple. Fistulas are more difficult to cope with.

How to fix a leak with your own hands

How to identify a breakdown and deal with it yourself.

Installation problems

Shortly after connecting, you may notice water dripping from the tank. In this case, the shell of the body can be inflated or deformed.

• During self-installation, you forgot about the safety valve, or it was connected incorrectly. As a result, the container overflows with water and inflates, after which it flows. The valve needs to be installed. It protects the system from overpressure.

• If the valve is installed incorrectly or if it breaks down, the tank is deformed when the water is drained from the system.
• You turned off the boiler and turned off the water. At this time, the hot water inside cools down and the body shrinks.
• The product is filled to capacity with water. During heating, it expands and the tank inflates.

In case of deformation, repair is impossible, you will have to install a new device.

Corrosion effects

Have you replaced the magnesium anode for a long time? Then don't be surprised that the boiler is leaking. Magnesium attracts salts in water. As a result, the sediments settle on the anode and destroy it, while the tank and the heating element remain intact. If the anode is destroyed long ago, corrosion of the metal body begins.

Such a development of events can be prevented only by replacing the rod once or twice a year.

Poor pipes or incorrect connection

Is water dripping from pipes or connections? Sealing the joints will help to fix and fix the problem: you need to replace the gasket or fum tape. It is recommended to use metal-plastic pipes, because as a result of water hammer, the body suffers.

Flange (gasket) worn out

The heating element and magnesium anode are mounted on a flange; a gasket is installed for tightness. If it is worn out, it will leak from the bottom. Replace it with a new one or tighten the fastening nuts tighter.

Heater body is corroded

Dry heating element has a steel and enamel shell - wear leads to corrosion.How do I repair a leaking item? Only replacement will help.

Instructions: Ariston water heater drip, what to do

Most of the time, the Ariston boiler leaks because its internal parts are not cleaned or cleaned out of time. Scale forms, destroying the parts of the water heater. This happens due to a large percentage of salts in tap water, an excessively high heating temperature, and, of course, untimely replacement of the anode.

Ariston water heater may leak due to untimely cleaning of internal parts

Transportation problems should not be ruled out. It happens that just at this moment the boiler receives a strong blow.

Weld seams lose their integrity, and it is through them that water will leak. And, of course, the wrong installation is also worth mentioning. For example, a safety valve was not installed, the parameters of this valve are not equal to the pressure in the water main.

We check electrical elements and heating elements

If everything is in order with the supply of electricity to the device, but the Ariston water heater does not turn on, then the tank is de-energized, and all the water is drained. After that, you need to dismantle the case cover - wires, thermostats and boards are located under it.

Then we use a tester - with its help we check the supply of electricity to the terminals of the heating elements. A situation is quite possible when the integrity of the power wires is broken, or there is no contact between the wire and the terminal on the heating element. The tester is also used to check the performance of the heating elements themselves, because they can burn out or punch onto the body.

If the spiral inside the heating element is out of order, the boiler will not turn on, since it will not be able to heat the water. With a breakdown to the case, it also will not work, because immediately after switching on, a residual current device (RCD) will work.

Keep in mind that a burned-out heating element cannot be repaired - only replaced, and if you are in doubt about choosing a suitable heating element, then it is better to contact the Repair Technician specialists. They will select a heating element that matches the brand, power and dimensions, and you do not have to deal with dismantling a heavy tank.

How to care for a boiler

So that leaks do not happen, and at one point the boiler does not expose you, let's say, a savings account, you need to properly and timely take care of it. For example, always before entering the pipe into the water heater, a high quality ball valve or valve must be installed. This part must easily withstand constant water pressure loads.

In order for the boiler to serve for a long time and efficiently, it must be properly looked after

Boiler maintenance:

• The gap between the boiler and the valve is a place for cleaning filters;
• Change from time to time filter membranes for new ones;
• Grounding is carried out strictly according to the instructions, use safety precautions.

To frequently flush the boiler, you just need to connect the hose to the lower outlet pipe of the heater, let the water flow into the body under strong pressure. The anode rod needs to be cleaned very often, and it is recommended to change it every year of operation. And the dip tube should also be cleaned in a timely manner.

Prevention of boiler service life

It is possible to extend the operating life of the device and ensure proper maintenance of the equipment by following the following recommendations:

• the internal water supply pressure must be below 3 atmospheres, otherwise a reduction reducer should be installed, which will be placed between the inlet pipe and the inlet branch of the device. The optimum gearbox setting is 2 atmospheres;
• the tank inside and the heating element must be cleaned at frequent intervals to remove scale and salt deposits. Thus, the service life of the unit will increase;

There are many reasons that affect the flow of the device, but if any of them occurs, you should immediately disconnect the device from the electrical network, and then carry out a visual inspection. It is forbidden to open the equipment without a precise determination of the cause of the malfunction, so as not to aggravate the situation, which may get out of control.

Only adherence to the rules of use and proper maintenance of the water heater contribute to the extension of the service life. If problems arise with an independent inspection of the unit, you should seek the help of professional specialists. They will quickly establish the cause of the failure and notify about the possibility of repairing the boiler.

The availability of a reliable and high-quality water heater Termeks provides apartment or house owners with hot water at any time. Cost-effectiveness, fast heating, reliability and long service life distinguish the equipment from competing products. Malfunctions and defects of boilers are recorded very rarely, therefore, the detection of tank leaks is always a nuisance and requires prompt elimination.

Each owner of a water heater, when leaks appear on the floor, can independently try to determine the cause of the defect. For this, it is often sufficient to perform a visual inspection of the device. Depending on the location of the leak, you can try to repair it yourself. Otherwise, it is best to use the services of qualified engineers working in our service center.

Classification and design features

Knowledge of the water heater device will help to carry out high-quality diagnostics and quickly determine the malfunction. Thermex electric water heaters are divided into 3 main types:

The main feature of such household appliances for 100 or 80 liters is the presence of an internal and external tank. The inner tank, as a part constantly in contact with water, is covered with a layer of glass porcelain. This technological solution excludes the appearance of corrosion. Polyurethane foam is poured between the outer and inner tanks - a material that prevents heat loss.

Thermex storage water heater

At the bottom of the device there are pipes for supplying and removing water, as well as all electrical components: thermostat, temperature relay and heating element - the main heating element. The heating element is a hollow metal tube with a spiral located inside, made of a material with high resistivity. Water is supplied to the boiler and heats up from the heating element when it turns on.

The main disadvantage of Termex storage boilers is high corrosion of the inner cavity of the tank, due to the exchange of ions between the heating element and the walls of the boiler. To minimize this effect, a magnesium electrode is installed, which supplies the water with the necessary ions.

Water heaters Termeks flow type

They differ from storage boilers in smaller sizes and a different principle of operation. In the design of instantaneous water heaters, several heating elements are provided - usually 2, but models with three or more heating elements are also available.

Instantaneous water heater Thermex

The heating elements are made of ceramic materials and are usually housed in a special copper cylinder. The installed power regulator allows you to control the temperature of the liquid passing through the boiler. Also, in addition to the regulator, a pressure sensor and a temperature sensor are installed. The pressure sensor turns off the water supply in case of exceeding its permissible amount in the water heater.And the temperature sensor is set at certain values, when exceeded, it turns off the heating elements.

Combined type

Such water heaters include a small-volume tank from flow-through devices and a storage principle of operation from simple boilers. The heating element has a different design, which is why it can operate in two modes: both a storage device and a flow-through device.

Combined water heaters Termeks have received universal recognition due to their positive qualities:

• Compact size, does not take up much space.
• They practically do not corrode, respectively - a long service life.
• Combined mode of operation.
• Average power, which is usually 2.5 kW. High-quality heating and a small waste of electricity.

Repair instructions

Inside, the most vulnerable place is where the two parts of the container are welded. In this case, the biggest difficulty is that there is a layer of thermal insulation under the casing, which is very difficult to dismantle.

Boiler device diagram

1. Disconnect the boiler from the network, drain the water, disconnect all hoses from the nozzles. We remove the plastic cover, for which we unscrew all the bolts (in Termex water heaters, one of them is usually hidden under a shiny sticker). We disconnect all the wires and take out the flange with the heating element, substituting a container in front of this, since the remaining liquid with scale will flow out.
2. We remove the already empty case from the wall. We flare the connections of the end parts of the shell from the side.
3. One of the most time-consuming steps is the dismantling of the thermal insulation. This is done with knives, metal hacksaws and other suitable tools. It is important to do this carefully so as not to damage the tank. Boiler cutaway
4. Then you need to clean the container from above. If there are obvious holes, you need to cut a thread in them, screw in the bolts and seal it on top with a piece of cold welding. At the end, the entire surface is primed and covered with several layers of paint.
5. It is advisable to check if the leaks have disappeared. For this, a flange is installed, hoses are connected and the boiler is filled with water.
6. If the water does not flow, we put the casing on top and fill it with polyurethane foam. We put on the end cover, roll up the edges and put the water heater back in its old place. Connection is made upside-down.

Causes of leaks and what to do?

During the flow of the device, it is initially necessary to establish the source of the negative factor. They can differ significantly in characteristics, so they can be identified quickly and without professional skills.

It is better to study the water heater according to the instructions attached to the instance.

Most models have a warranty card for these situations. In order not to aggravate the problem, the device must not be opened.

Deformation of the case

Safety valve
The outer shell of the equipment may deform after installation. Incorrect installation of the unit is considered to be the reason for the unfavorable behavior of the device.

Often the consumer forgets to connect the safety valve.

The product is located on the main fluid supply between the stopcock and the valve element.

This part is provided for tank overflow protection, it is during this process that deformation occurs.

If the valve is installed, but the flow of water is also carried out through the supply pipe, remove this fuse and install a new one. The repair does not take much time and does not require professional knowledge of the device.

Another reason for deformations is the use of low-quality pipes during installation. Powerful water hammer with pressure change slowly destroys the product structure.

Tips for Extending Life

For the longest possible service life of the water heater without breakdowns, it is important to follow the manufacturer's recommendations for its installation and use. This applies to any technology that provides heating or water heating. When installing the boiler, it is important to provide grounding, magnesium anode, safety valve.

1. Before installing the device, it is imperative to check the pressure in the system. Normal indicator: up to two atmospheres. If the indicator exceeds more than 3 atmospheres, this pressure must be reduced, for which a reducer is installed in front of the device, which will prevent an increase in temperature.
2. The optimum temperature for the boiler is up to 50 ° C; it is not recommended to set more than this value.
3. Clean periodically (2-3 times a year), it is important to monitor the condition of the rod.
4. It is recommended to connect the device to the water supply system through a special magnesium filter, which is better purchased simultaneously with the purchase of a water heating device. This will reduce the hardness of the water if they are very high or there are a lot of impurities in the water.
