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.
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.
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 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.
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.
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.

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. The exact same plug can be located on the left stiffener rib (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
Use a small curly screwdriver to 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.
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.
We will show you how you can make a DIY repair of a water cooler, AquaWork model 36TDN, if it does not cool. Our cooler has electronic cooling, a peltier element and a cooling fan are responsible for it. If your cooler does not cool the water, the reason for this should first of all be looked for in the two above elements. In 90% of cases, the thermoelectric cooler and fan fail.
Unscrew all the fastening bolts on the back of your water cooler case with a regular Phillips screwdriver.
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.
In the process of everyday operation of water dispensers, a number of malfunctions arise, for the elimination of which it is not always necessary to call a master or service a service center for the repair of coolers.
You can try to fix some breakdowns on the spot, with your own hands, on your own.
Remnants of the protective hygienic cap from the bottle cap prevent water from entering.
Remove the bottle and remove any remaining protection.
If the problem persists, remove the filler neck by turning it at an angle of 10-15 degrees counterclockwise, check the contents of the distribution tank.
Always manually remove the hygienic protective cap from the bottle cap before placing it on a top-loading machine.
The remnants of the label, getting inside, not only pollute the clean water you buy, but, accumulating, gradually disable check valves, taps and other elements of the cooler.
An “air lock” has formed preventing water from entering the dispenser.
Shake the bottle slightly until you can visually detect air bubbles entering.
The bottle has run out.
Make sure there is water in the bottle.
The pump supplying water from the bottle to the top does not work.
Check the connection of the device to the 220V network.
The water sensor is not working properly.
Try removing and reinstalling the bottle water tube.
Get in the habit of turning off (using the toggle switches located at the back of the case) cooling and heating when the water is exhausted and turn it on only after installing a filled bottle and checking the flow of liquid from the taps.
After inserting a full bottle and turning on the toggle switches, wait a few minutes for the Heating and Cooling indicators to turn off.
Microcrack in the walls or bottom of the bottle.
Examine the bottle, try to locate the leak.
In case of defects in the bottle, water should flow out in a thin stream from the gap in the gap with the bottle and the neck.
Usually such a trickle is practically invisible to the eye.
Carefully remove the bottle from the dispenser and call your supplier.
Polycarbonate containers are used many times, but they do not last forever.
The life cycle of a bottle is on average 50-70 uses.
Any bottle undergoes several checks: during acceptance, cleaning, on the filling line, at the supplier's warehouse, at the delivery warehouse, but alas:
Aqua Market quickly replaces such bottles ordered from us with full ones free of charge.
The absence of a valve on the drain hole.
Check valve is present and tighten tightly until leak is eliminated.
Drain valves are usually located on the back of the apparatus, in compressor models it is usually 1, in electronic models it is 2.
To avoid damage to property and short-circuit wiring, do not install the device near expensive furniture and household electrical appliances.
Such devices are capable of cooling about 0.6-1 liters (i.e. 3-5 glasses) of water per hour at a temperature of about 12-15 degrees below the environment.
Move the dispenser to a cooler and more ventilated place, remove the body and bottle from direct sunlight - these measures will help remove a few degrees of heat from the water.
Check the working order of the fan installed inside the cooler (on the back of the device) - it should work to blow out air.
There must be an air gap of at least 20 cm between the back wall and the furnishings of your room.
Failure to comply with this rule not only reduces the cooling efficiency, but can also damage the device.
Too heavy use
A typical dispenser is designed to heat up to 92-97 ° C for about 5 liters per hour. The capacity of the internal tank with already heated hot water is usually enough for 2 cups (400-500 ml).
Before pouring the next glass from the “hot” tap, make sure that the heating indicator has turned off, otherwise the cooler may not have time to heat the water for you.
Check the presence of current and the position of the toggle switches of the heating and cooling systems
After turning on the machine, wait a few minutes until the heating and cooling indicators go out.
The heating rate is also affected by the formation of scale on the walls of the hot water tank. To remove it, you must periodically clean the cooler yourself or with the help of specialists.
We recommend to carry out such processing at least once every 6 months.
To slow down the scale formation process, it is necessary to use only high-quality drinking water with a low salt content, for example, from the Aqua Market assortment.
We sell spare parts for water coolers and other Aqua Work equipment, which we supply to Russia.
A number of components: taps and buttons, temperature sensors, control boards, heating tanks and cooling systems, compressors and peltier elements are successfully used in the repair of similar coolers AEL, AquaWell, BioRay, BioFamily, Ecotronic, HotFrost, Lesoto, Smixx, etc.
We are constantly updating the reference section and adding answers to questions that are most often encountered by Aqua Market buyers.

Failure to comply with the rules of transportation and storage conditions, technical requirements for the installation and operation of dispensers is one of the most common reasons for their breakdowns.
Check if it is plugged into the network (+ the button is on at the back or not), and if it is on, the power indicator light on the front panel is on (usually orange). If the light is off, then first check the outlet with another device.
The socket turned out to be working properly, we check the plug and the power cord (by pulling the plug out of the socket) for tears and cracks, if any, we fix it. If this is not the case, then we are looking for a fuse on the cooler on the back panel for the floor ones and inside (you need to unscrew the back cover) for the desktop ones. It turned out not whole - we change.
If the network status is shown on the panel, the light is on, but there is no heating, then turn off the network and unscrew the back cover of the cooler. We opened it, we see a hot water tank and two sensors (black, round with connected wires) on it. The lower sensor in the center has a button, it must be pressed until it clicks (if there is no click, then the sensor did not work or it’s not in it). Then we check whether the cooler is working or not, turn it on (is the red heating lamp on), and turn it off immediately if the heating indicator is on (if the cooler is without water). If the problem has not been resolved, then the matter is in the heating element, most likely it is out of order and must be replaced.
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 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.
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 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.
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:
Open the back cover of the cooler.
Find a container for heating water (usually located at the top of the device).
VIDEO
Additionally, you should check the heating element (thermoelectric heater), since damage to its integrity or a decrease in resistance can also lead to a deterioration in the quality of water heating.
Remove the heating element from the heating tank.
VIDEO
Partial or complete loss of the cooler's functionality, as well as an unpleasant taste of water, may appear due to accumulated dirt. In order not to bring the device to a neglected state, it is necessary to clean it from dust on a monthly basis. Before starting this process, it should be remembered that four things are prohibited: washing the cooler under a tap or shower, installing the device in a dishwasher, disinfecting with a steam cleaner, and using abrasive detergents (powders and solvents).
In order to clean and disinfect the cooler, you need to do the following:
VIDEO
A decrease in the quality of water and a deterioration in taste can occur not only due to contamination of the apparatus, but also due to the loss of their properties by filters. In order to replace the filters, you need to do the following:
Take a screwdriver and unscrew the two screws on the back panel.
Remove the top cover or open the back cover of the device (depending on the model).
Disconnect the corner fittings.
Most cooler manufacturers recommend adhering to the following filter replacement schedule.
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.
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.
