Water cooler bioray DIY repair

In detail: a bioray water cooler DIY repair from a real master for the site my.housecope.com.

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 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 on (we have had such cases) and, 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.

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 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:

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 is constantly leaking, dripping from the tap, then you cannot cope with the problem with your own hands: only the specialists of the service center can remove this malfunction.

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.

Sudden problems in the operation of a floor-standing or desktop water cooler may arise at the most inopportune moment, since repairing a cooler in a service center requires money and time, which may not be available. In most cases, the reasons why the cooler or its individual functions (such as water cooling) do not work, arise as a result of careless transportation of the dispenser, its installation or operation. But before calling the wizard, let's try to understand the problem in order to find an alternative way out of this situation.

Suppose everything was fine yesterday, but today you found that the cooler is not working or is working, but the process of cooling the water is too slow. The reason may be the most commonplace and easily eliminated, but sometimes repairing a cooler in a specialized service center is the only way to eliminate the malfunction. First, we recommend that you familiarize yourself with the following list of possible problems:

If the dispenser is used by a large number of people, then the water for the cooler may not have time to cool down to the required level. Depending on the type of cooling, give the appliance enough time to cool down the water (about 15 minutes).
Another possible source of this problem is an improperly adjusted water thermostat that is set at a low or minimum level. Try changing the current settings to improve the current cooling performance.
In the absence of normal conditions for ventilation, the cooler does not cool the water to an optimal level. First of all, you need to make sure that there is a small air gap (at least 10 cm) between the equipment case and its surroundings.
Overheating of the elements responsible for the cooling function can also be a probable cause of insufficient water cooling. Just unplug the equipment from the mains and leave it off for about half an hour.

If the cooler does not cool the water at all, then first of all it is worth looking at the corresponding indicator. There may be a power outage, a problem with the outlet, or the dispenser may not be plugged in. Make sure the cooler is plugged in and check for voltage.
Another cause of the problem may be related to the position of the toggle switch, which is responsible for the water cooling process. Try turning on the toggle switch located on the back of the case. The correct position of the toggle switch can be found in the instructions that came with the cooler.
In coolers with an electronic type of cooling, the fan could fail or the Peltier element burned out. This happens very often when the dispenser has been used for a long time in a poorly ventilated area. In this case, you will have to replace the damaged parts, which means that you cannot do without the help of specialists.
In coolers with compressor-type cooling, the compressor may break down, which needs to be repaired or replaced. Freon leakage may also occur, resulting from the appearance of microcracks during careless handling of the radiator grill. If this is the problem, contact the service center, where you can identify and solder the leak, and also pump in a new portion of the refrigerant.

As you can see, most common cooling problems can be solved by yourself. And nevertheless, if your cooler does not work or does not cool the water, then it is better to play it safe and immediately call a foreman who will carry out a comprehensive diagnostics of the equipment and prevent further aggravation of the problem.

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 hand, 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, taking special care 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.

Cleaning the water cooler is a mandatory procedure that should be carried out approximately every 3 months.

Before cleaning the cooler, it must be disconnected from the power supply. After that, the device is placed on a special waterproof mat and the bottle is removed. The remaining water is drained first from the hot water tap and only then from the cold one. In order for the water to drain completely, it is recommended to tilt the cooler to the left and then to the right. But the process of getting rid of the liquid does not end there.

There is an additional drain valve on the back panel. It should also be opened to completely drain the water from the system. Additional slopes in different directions contribute to the complete drainage of the liquid.

In order for the water to drain completely, it is recommended to tilt the cooler to the left and then to the right.

When the system is empty, it is recommended to initially clean the device externally. As a detergent, you can use ordinary dishwashing detergent, soapy water, or purchase a special substance for cleaning the machine for water. All external parts are processed. Special attention should be paid to cranes. Unscrew and rinse from the inside. The receptacle for collecting liquid residues also contains many microbes, which must be disposed of.

It is recommended to purchase special small brushes for cleaning the taps. After all the elements are washed, the taps are screwed into their original place, but the cleaning process does not end there. When the drip tray is cleaned and the body is washed, you can proceed to sanitizing the bottle connection.

Before starting cleaning the cooler, it must be disconnected from the power supply

For further disassembly, you need to turn the bottle receptacle counterclockwise. The disassembled unit is thoroughly washed with soapy water.

After the bottle receptacle is removed, the tank itself opens, into which water flows from the bottle installed on top. A divider is located at its bottom.It must be dismantled and also thoroughly washed with soapy water, and then rinsed with clean water.

Cleaning a water tank at home is also easy. You don't have to buy expensive cleaning products. At this stage, you can use the products that are present in almost every kitchen. An aqueous solution of citric acid is used to remove contaminants.

To prepare a cleaning solution, you will need to take 20 g of citric acid per 1 liter of water. To clean the device properly, you need about 5 liters of liquid. The homemade cleaning solution is gradually poured into the container. In order for the liquid to spread throughout the system, it is necessary to open the hot and cold water taps. As soon as liquid begins to flow from them under the maximum possible pressure, the valves are closed and the cooler is connected to the electrical network. There are 2 toggle switches on the back panel - for heating and cooling. Only the heating mode is turned on, and the cooling remains in the off position.After heating the liquid, when the indicator goes out, you need to turn off the toggle switch and unplug the cooler plug from the socket. At this stage, nothing else depends on the person who performs the cleansing. You need to wait until the water cools down. This will take approximately 5 hours, during which the citric acid will destroy all existing contaminants.To complete the self-cleaning procedure, after cooling the citric acid solution, you need to arm yourself with a washcloth. It is not recommended to use materials that have abrasive particles. They will only provoke the appearance of unnecessary scratches in which dirt will accumulate in the future. After prolonged exposure to acidic water, the surface can be easily cleaned by rubbing it with a soft washcloth. It is necessary to ensure that no mucus remains on the walls. Next, the water is drained through open taps. If necessary, you can repeat the rinsing process. Do not forget about the drain cock, which is located on the back panel. It should also be opened each time as soon as it becomes necessary to completely drain the liquid.The divider is returned to its place, the container is refilled with clean water in order to rinse the cooler and remove the remaining dirt. The liquid is drained again.

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:
