DIY ael cooler repair

In detail: do-it-yourself ael cooler repair from a real master for the site my.housecope.com.

Coolers or water dispensers are becoming more and more popular every year, and such devices can be used both in office premises and in an apartment. The need for clean water will never decrease. Any equipment from time to time, regardless of quality and manufacturer, may become faulty. If the breakdown and malfunction are light, then the repair can be done by hand, without contacting service centers.

High-quality repairs can only be made if the reason is identified. Before disassembling the device for water purification, carefully read the instructions for the cooler, which indicates possible malfunctions and solutions.

There can be many reasons for the malfunction. Often there are those that can be eliminated fairly quickly. Let's take a look at them.

If dirt has accumulated in the cooler, then it will stop working - it will need cleaning.

First, the device is disconnected from the mains and the water bottle is removed.
The surface of the cooler should be thoroughly rinsed using ordinary dishwashing detergents. The work must be done carefully, especially in the place where the needle is located, on which the container for the liquid is put on.
Then they take up the pallet. It is thoroughly washed, rinsed.
All parts of the dispenser are wiped dry with a soft cloth.

Then all the elements of the device are returned to their places. Pour water into the bottle and drain a little through the faucet. This is necessary to flush the tap, as some detergent may remain in the tap.

Most often cause of malfunction is as follows:

The device is not connected to the mains.
We did not click on the "enable" button, which is located on the panel.

After carrying out the necessary operations, the indicator still does not light up, check the outlet itself. It's easy to do: take any electrical appliance and plug it in. If it does not start working either, the reason is a malfunction of the outlet itself: either replace it, or plug the cooler into a different outlet.

If the cooler does not start working in it, you will have to disassemble equipment:

Video (click to play).

We remove the panel on the rear panel, check the fuse is working. If necessary, insert a new element.
Again, nothing happened, which means that the reason is in the heating element. In this case, the malfunction can only be eliminated at the service center.

There are only two reasons for the appearance of such a malfunction:

When installing the bottle, they forgot to remove the label.
During operation, a plug of air appears in the tank, which does not allow the cooler to work efficiently. It is easy to eliminate the inoperative state of the installation: the dispenser is pumped until air bubbles appear in the water tank itself.

If the owners use the cooler correctly, follow the instructions, then, as a rule, such misunderstandings do not arise. In addition, checking the operation of the taps should be done every time the water in the bottle is changed.

If you notice that from the dispenser water spontaneously flows out, check the integrity of the container. Perhaps microcracks have appeared on it. You can eliminate this error yourself. To do this, remove the damaged bottle and replace with a new plastic container.

If liquid constantly leaks, dripping from the tap, then you cannot cope with the problem with your own hands: this malfunction can only be removed by the specialists of the service center.

Electronic coolers often suffer from this disease. This is due to the design of the equipment and technical capabilities.Cooling of one liter takes place in an hour, while the water temperature can be fifteen degrees below the ambient air.

The coolers do not have great performance capabilities. These devices do not belong to high-performance appliances... If you need colder water, then the cooler is installed in a cool room out of the sun.

The technical parameters of the coolers are to blame for the malfunction. In a standard device, no more than five liters of water can be heated in one hour. If the liquid is poured in a larger volume, then the cooler does not have time to heat the water.

This is not a breakdown of the device, it can be easily eliminated if the instructions for use are followed. But the presence of scale contributes to the fact that the water will not heat up quickly enough.

The cooler should be mechanically cleaned from time to time. The work is carried out depending on the model and recommendations.

Steps for disassembling the cooler:

Self-tapping screws are unscrewed from the back wall using a curly screwdriver. A tank with temperature sensors, in which the water is heated, is located at the top of the device.
On the right, a drain plug is rigidly attached through which water is drained. There is another plug on the left, which is removed to drain the cold water in the cooling system.
Taking the key number 15, you need to remove the rubber seal. Using a small curved screwdriver with a long enough handle, remove the 4 screws.
We dismantle the heating tank by cutting off the clamps from the branch pipe, and then all the pipes.
Then we are engaged in the removal of power wires, thermal sensors, ground wires with six screws.
If, after removing the tank, there is no paste on the seats, then you need to cover them with thermally conductive paste.
After that, we begin assembly, starting with the last removed part.

After completing the assembly, fill the system with water. We check how it flows. After that, it remains to connect the device to the network. If the indicator lights are working properly, then the problem has been fixed. You can watch the video in more detail about this operation.

Other troubles:

The cooler may fail if it was turned on when there was no water. Heating elements heat up and burn out.
The pump has failed. You need to connect the cooler to the network and check the operation of this element.
When installing the cooler, make sure that there is a distance of about 10 cm between the device and the wall. Otherwise, the device may quickly become unusable.

Use water with a low salt content, then scale will not appear soon.
Do not leave the cooler plugged in if it runs out of water.
Never disassemble the device yourself if the cooler has not expired the warranty period.

DIY HotFrost cooler repair

Let's consider several cases of cooler repair, for example, let's take a cooler of the HotFrost802CE model.

This article is designed primarily for those people who have the necessary skills to work with electrical appliances, who are able to give an account of their actions themselves. After all, repairing a HotFrost cooler with your own hands is quite a serious matter. And he must be approached with all responsibility. For the rest, the inscription on the cooler “DO NOT OPEN”, which means “DO NOT OPEN” in Russian, should be the final phase in the repair of the cooler. There is no need to climb further. Trust the professionals better. Take your cooler to a repair shop where it will be brought back to life for you.

What to do if the cooler does not heat (does not boil) the water?

The photo shows that there are a total of three indicator lights. If shines yellow indicator, it means that the device is connected to the network. It always burns. Red indicator responsible for heating. It goes out when the water is heated to a temperature of 96 C, and, accordingly, is suitable for making hot drinks (tea, coffee). Green indicator signals the operation of the cooling system. As soon as the cold water temperature reaches +5 C, it turns off.But what if the red indicator is off and the water from the hot tap is cold?

If your cooler does not heat up the water and, at the same time, the heating indicator does not light up, as shown in this photo, then in 90% of cases the cooler has the following faults:

a) one of the temperature sensors (very rarely both come out at the same time)

b) defective Heating element of the heating tank

In order to repair any equipment yourself, including a water cooler, you need to stock up on a tool. So, for example, in our case, you will need the following tools:

b) 15 "open-end wrench

c) small Phillips screwdriver

you will also need plastic clamps necessary to tighten and seal the connections

In order to start the repair, you must first de-energize the device, then remove the bottle and drain all the water from it.

This is the rear view of the HotFrost cooler

Use a curly screwdriver to unscrew the self-tapping screws that secure the rear decorative panel.

Having removed the rear decorative panel, we can proceed with further repairs.

So, a heating tank with thermal sensors installed on it is located in the upper part of the cooler. In the enlarged photo of the upper part, the tank is located in the lower left corner.

these are the screws used to attach the rear decorative panel of the cooler

On the right stiffener rib, we can find just such a drain plug. It is necessary in order to completely drain the water from the heating tank. Exactly the same plug can be located on the left stiffener (for some cooler models) and serves to drain cold water from the cooling system.

Remove the drain plug cap by turning it counterclockwise. Then remove the rubber seal

Use a 15 ″ wrench to remove the drain plug nut

This is how the cap, rubber seal and drain plug nut look (from left to right, respectively)

We release the drain plug from the bore hole

The tube goes through a hole in the plastic support on which the heating tank is attached

Using a small curly screwdriver, unscrew the heating tank fastening screws counterclockwise

There are only four fastening screws. The difficulty in removing them lies in the fact that there is very little space for a screwdriver, so you need just a small screwdriver, with a total length of no more than 60 mm with a handle

Having released the fasteners, we proceed to dismantle the heating tank itself

We cut off the clamp of fastening of the water supply pipe with pliers

Cut off the clamps of the upper branch pipes with pliers

We remove all pipes supplying water to the tank

We remove the power wire. It is through it that voltage is applied to the heating element. There are only two power wires. Red and black. There is no difference in the disconnection sequence.

We remove the second power wire

We remove the temperature sensors and two ground wires

And the temperature sensors and two ground wires are fastened with such screws. There are only 6 of them.

And this is what a thermal sensor looks like.

And finally, after so many procedures, we got out the heating tank.

As you can see, the seats for the thermal sensors are treated with a special white heat-conducting paste.

This is how the new heating tank from the cooler looks like.

As you can see, the seats for the temperature sensors are clean. They need to be coated with thermally conductive paste for better operation of the temperature sensors.

Have you got a cooler? Have you decided to try if it "turns on", but there is no water? Think to yourself, well, I'll just plug it in and check if the indicators are on, and that's it. What's wrong, I'm fast? This is the main mistake of a beginner when connecting a new or long-unused device for the first time. Then you will definitely call us and say that the cooler does not heat the water at all, and you personally acted according to the instructions.In fact, you are very lucky, because we wrote this quick guide and saved about a thousand rubles from your wallet, because that is how much you have to pay for removing the thermal protection, and sometimes the cost of removing the protection depends on the price of a water cooler.

As a rule, thermal protection is triggered due to domestic carelessness, or due to neglect of the quick start guide attached to each water cooler sold. Attention, you can plug the cooler into the network only after making sure that the heating and cooling tanks are completely filled. If this condition is not met, this ill-fated thermal protection will work in the device, which protects the heating element from burning out. In order to turn it off, you need to arm yourself with a long screwdriver and be sure to disconnect the cooler from the outlet. Although it is better to check beforehand if the heating toggle switch on the rear panel is turned on (we have had such cases) and, after making sure that it is on, we proceed further.

Let's look at the back of the device, and through the compressor grill (in an electronically cooled cooler, you need to remove the back cover) you should see the heating tank. It is a cylinder wrapped in insulation. There are two contact groups on the tank, two contacts each. Just between the contacts on one of them (usually on the top), there is a thermal fuse. It looks like a small black button or microswitch, which must be slightly pressed with a screwdriver ... After all these actions, we will drain one glass of water from each tap, this will give us the opportunity to make sure that the heating and cooling tanks are full. Now you can plug the machine into an electrical outlet and turn on the toggle switches.

A water cooler is an indispensable assistant in the office, as well as in the house, when you always have high-quality clean water at your fingertips, hot or cold. But, like all technical units, coolers sometimes require maintenance and repair. From time to time it will be necessary to restore the heating in the cooler, which will require a heating element for the cooler price in Ukraine.

The first thing that needs to be done to repair the cooler is to clean it. It happens that problems with a cooler arise precisely from contamination. Therefore, the first step is to clean the cooler.

The cooler should be cleaned regularly, regardless of heating or cooling problems. It is better to plan maintenance of equipment than to fix faults at the wrong time.
For cleaning you will need:
1.damp cloth or napkin
2.detergent
3.Dish washcloth (new)
4. screwdriver
Unplug the cooler from the mains, remove the water bottle. Wash the surface with a sponge cleaner. Pay special attention to the needle on which the water bottle is being put, being very careful not to damage it. The next step is to thoroughly wash the pan under running water and wipe it dry. Then the cooler is assembled in reverse order and try to plug it into a power outlet. If the cooler starts working properly, it means that the reason was contamination.

Remember that the cooler needs to be cleaned regularly to avoid the ingress of pathogens into the water.

There may be several reasons why the cooler does not heat the water:In the case of the last two reasons, we recommend contacting the service center of the manufacturer or service company. But if you have the opportunity to disassemble the cooler yourself and change the failed elements, it will be cheaper.
The sequence of disassembling the cooler:

Remove the panel on the back of the cooler

Check the fuse is working. If necessary, we will replace it with a new one.

We check the heating element - ten. If the reason is in it, then you can buy a heating element for a cooler and make a replacement with your own hands. Although companies recommend replacing the heating element only at service centers.
Of course, if your cooler is under guaranteed service, we do not recommend repairing and cleaning the system yourself. It is better to contact the company as planned and the professionals will do all the necessary operations themselves.

Next, remove the back cover. Now you need to start the cooler with the rear cover removed. When the power is on, we observe that the fan is not spinning, the problem is in it. We remove the old fan, the photo below shows the bolts that need to be unscrewed to dismantle and then change it to a new one.

After installing the new fan, we check its performance with the rear casing removed, everything is fine - the fan is working. Now you can screw the back cover back on.

As a result, we can say that the task of repairing a cooler with your own hands is not so difficult. In our case, we got by with a banal replacement of the fan.

The main thing to understand is that this article is applicable to help you repair an electronically cooled cooler (using a peltier element). If your water dispenser is compressor, then it will be more difficult for you to diagnose and repair yourself, in the event of a breakdown, for example, of the cooling compressor of a cooler.

The days when drinking tap water was tasty and healthy and could be drunk without additional filtration are long gone. At present, the quality of water supply has significantly decreased, and it is for this reason that special devices - water coolers - are increasingly appearing in office premises, as well as in enterprises and public places.

A cooler is a device designed to provide employees and visitors of enterprises, offices, city and private companies, as well as other facilities with drinking cold and hot water. It is a structure consisting of a container with drinking water (usually a plastic bottle with a capacity of 19 to 30 liters), a dispenser, a connecting pipe and a check valve.

After connecting the tank, the liquid enters the dispenser distribution system, which consists of containers for storing cold and hot water. First of all, the liquid enters the cold water tank, from where it is fed through the connecting pipe to the boiler, where hot water is prepared. A check valve is installed between the two tanks, which balances the pressure of the system and prevents the intersection of water flows.

The cooler consists of tanks for cold and hot water, between which a separating check valve is installed

The main parameters by which water coolers differ are:

water heating and cooling power;
heating and cooling performance;
cooling technology;
method of loading a container with water.

Water coolers are divided into several types depending on the installation method and the mode of cold water supply.

If you plan not to use the device for a long time, you should disconnect it from the power supply.

compactness;
dual mode (cooling and heating water);
variety of models;
availability of additional functions of carbonation and water filtration;
built-in storage compartment for various utensils (not in all models);
suitability for intensive use;
ease of use.

independence from the available water supply;
no restrictions on water consumption;
deep cleaning degree;
profitability due to the low cost of tap water.

the need for periodic filter replacement;
high price;
inability to move after installation;
dependence on the water supply system.

Depending on the cooling technology used, there are two types of coolers: electronic and compressor.

The operation of coolers with an electronic cooling system is based on the passage of an electric current through conductors that are cooled at their junctions.

the cooling rate is about 3 l / h;
reliability and environmental friendliness. Devices of this type do not use freon, so they are free from refrigerant leakage problems;
light weight and low cost.

Coolers with a compressor cooling system operate by using a refrigerant - freon, which is also used in refrigerators.

Compressor coolers work on the same principle as household refrigerators

Features of compressor coolers:

durability and strength;
high performance;
the ability to adjust the cooling temperature.

ease of use;
compactness;
low cost of installation and maintenance work;
noiselessness;
possibility of transportation in a horizontal position.

reduced performance;
undesirability of installation in dusty and unventilated rooms (otherwise more careful maintenance is required);
relatively slow cooling of the liquid;
low productivity (the device can be served simultaneously by no more than three people).

the ability to adjust the water temperature;
high performance;
cooling to sufficiently low temperatures.

The scheme and device of the cooler depends on its type and purpose, as well as on the technology of water filtration.

The flow-through water cooler consists of a four-stage filter, an ultraviolet lamp, tanks for hot and cold water with appropriate elements (heating and cooling). The use of a large number of filters and a UV lamp is due to the fact that the water supply system (plumbing) is used as a source of water. They interfere with the reproduction of viral and bacterial particles.

The flow-through cooler has a four-stage filter and an ultraviolet lamp, which are necessary for preliminary purification of tap water

The compressor-cooled cooler consists of the following components:

The choice of a drinking cooler is a rather crucial step, since the quality of water and, accordingly, the health of people will depend on its type and device. When choosing a cooler, you should be guided by the following characteristics:

The size of the apparatus.
Filtration technology. The most preferable would be a device with a multistage water purification system.
The presence of an ultraviolet lamp, especially if children are expected to drink the water.
The temperature of the water inside the device. Better if it is +98 o С for hot water and +4 o С for cold water. An additional advantage will be the ability to regulate the temperature.
Additional functions: child protection, dispenser, timer (programming the cooler for automatic on / off).

Despite the fact that the water cooler is a household appliance, it is designed for long-term use and therefore requires periodic maintenance and sometimes repair. To carry out these works, the device often needs to be disassembled.

In order to disassemble the cooler, you need to do the following:

Take a curly screwdriver and unscrew the screws.
Remove the rear cover. Dismantling the cooler begins with removing the back cover, which is attached to the case with self-tapping screws.

Further analysis depends on the type of malfunction.

During operation, a variety of malfunctions can occur, ranging from elementary ones that can be corrected on their own, and ending with complex ones associated with the breakdown of electromechanical components.

The weakening of heating may be due to the fact that scale has formed in the hot water tank during operation.... In order to check the presence or absence of scale, you need to do the following:
