Atlant 45u101 DIY repair

There are several questions.
Does the firmware store any information about errors and so on?
There are no complaints about the operation of the machine “seemingly”.
At the very beginning of the check, there was not quite adequate behavior, but I attributed everything to the selector.
For the sake of interest, I leaked the firmware.
Here https://my.housecope.com/wp-content/uploads/ext/2255/forum/viewtopic.php?t=339354&postdays=0& . I found the firmware for a similar machine, downloaded it, when comparing it turned out there is a difference.
Who can say anything about this situation?

In this article, we will consider the Atlant washing machine troubleshooting system. This brand of household appliances is well known in our country thanks to well-established refrigerators. And recently, the owner of the brand has been very actively promoting washing machines of his own production to the market. It is worth noting that the equipment of this brand is in no way inferior to well-known world leaders.

These machines are equipped with modern control modules that have the function of self-determination of faults. If a breakdown occurs in the machine, the system itself determines the faulty node or component, and then displays the corresponding code on the display. Fault codes are displayed as a combination of a Latin letter and a number. For example, the error f4 burning on the display of the Atlant car tells us about a malfunction in the drain system, and the error f5 burning on the display of the Atlant car tells us about a malfunction in the water inlet system.

If there is a display, the errors of the Atlant washing machine are displayed in an understandable way, but what if there is no display? In this case, atlas errors are displayed as a combination of flashing indicators (light diodes) on the control panel.

The photo below shows four indicators by which Atlant errors are determined.

Each light diode has its own numerical value:

• The indicator "wash" corresponds to the value 8;
• The indicator "rinse" corresponds to the value 4;
• The water stop indicator is set to 2;
• The "spin" indicator corresponds to the value 1.

If several indicators are lit, they need to be summed up, this will be the code. Let's consider a few examples of how to determine the errors of the Atlant typewriter by indicators.

For example, the F4 error looks like this on an Atlant car:

as you can see, the “rinse” diode is on.

And this is what the F5 error looks like on an Atlant car:

the “rinse” and “spin” diodes are on, we sum up the numerical values ​​​​that correspond to them, and we get: 4 + 1 = 5, F5.

Next, we will consider the errors of the Atlant washing machine in more detail, in the table below "Atlant error codes".

Belarusian washing machines Atlant have not only an attractive external design, but also good technical characteristics. Of course, they can compete in these parameters, but hardly in terms of reliability and durability. Therefore, the repair of Atlant washing machines is not such a rare phenomenon, as experts say. Undoubtedly, it is easier to give the machine into the hands of the master, wait a couple of days, and then wash it in the previous mode, but in some cases you can fix the problem yourself, reducing cash costs. Let's figure out what these cases are, and what needs to be done in this case.

You can find out the cause of the breakdown and unstable operation of the washing machine by the characteristic symptoms that appear during washing, spinning, and water intake. Most often, users of Atlant machines turn to the masters with the following symptoms:

• The machine stopped turning on.There may be several reasons for this. Faulty socket, wiring inside the machine, failure of the Start button or control module.
• The machine does not spin the laundry. If the laundry remains damp, even wet, this means that the motor has broken down, or the contacts on the motor have oxidized. It is possible that the cause of poor spinning is a malfunction of the control module. If the spinning process does not start at all, and the machine “freezes”, then, most likely, the laundry has gone astray in the drum, an imbalance in the load has occurred.
• The machine does not drain water. In this case, the cause is a breakdown of the drain pump or a blockage in the drain hose.
• The machine "jumps" and knocks during the spin cycle. This indicates the need to replace the bearings.
• The machine washes in cold water. This is a common failure, the cause of which is the failure of the heating element.
• Water is leaking from the machine. The causes of this malfunction must be sought depending on where the water flows: under the machine, through the hatch door or through the powder receiver. This means that the breakdown must also be sought in the relevant details: the drain hose has broken, the pipes or seals have worn out, the cuff has torn.

By carefully listening and looking closely at your washing machine, you will not miss the moment and find a malfunction in time. In some cases, it is simply impossible to delay the repair.

In many cases, the error codes that appear on the display of the Atlant washing machine help to determine the cause of the malfunction. It is also worth noting a good system of self-diagnosis of faults in some models of machines. You cannot describe detailed instructions on how to start the self-diagnosis mode within the framework of one article. The fact is that on different models of machines, the launch may differ, so it is best to read the instructions that came with the machine, or download the instructions for a specific model on the Internet.

If the machine does not turn on, then the first thing to check is the performance of the outlet. To do this, you can turn on another household appliance. If the problem is not in the outlet, you will have to check the power cord, surge protector and control board one by one. To get to the electrics of the machine, just open the top cover, which is attached with two bolts.

Having provided yourself with access to the electrics, inspect all the terminals and wires, perhaps already at this stage you will see burnt and oxidized elements. After inspection, you need to take a multimeter and ring the surge protector and cable. If it turns out that the cable is defective, then it must be replaced with a new one. Sometimes the cable is sold complete with a surge protector.

If the electrician of the machine has nothing to do with it, then the reason that the machine does not turn on is the electronics, in particular, the Start button may not work. It is difficult to deal with such a problem on your own. Therefore, it is better to entrust the diagnosis of an exact breakdown and its elimination to a specialist.

Important! When working with the control module, you need to have certain knowledge in this area, otherwise, if at least one wiring is not connected correctly, a working board may burn out.

A frequent breakdown in washing machines is a breakdown of the heating element. As a rule, it fails due to physical wear and tear, hard water shortens its service life. Scale settles on the heating element, as a result of which the load on it increases. You can replace the heater in the washing machine with your own hands.

1. Disassemble the machine, or rather remove the back cover of the case.
2. Next, under the tank, find the heating element itself, or rather its terminals.
3. Disconnect the supply wires and the ground wire, and also disconnect the terminals from the thermistor, if it is built into the heating element. In some models, the temperature sensor is installed separately.
4. We loosen the central bolt by turning the nut a few turns counterclockwise, and try to push it inward.

Pay attention! In Atlant washing machines, it is not easy to pull the heating element out of the holder, since the sealing gum strongly “sours” or is pressed in during installation.

You need to take a flat screwdriver and pick up the heating element by the base, then pull it towards you with loosening movements from side to side.

Before installing a new heating element, do not forget to clean the “nest” from scale and debris.

Assemble everything in reverse order.

A malfunction of the water level sensor (pressure switch) usually manifests itself when water is filled and drained. The sensor does not send a signal about the level of water taken in and the tank may overflow with water, or the machine may even stop before spinning, since the pressure switch does not signal the drained water, or the laundry will be poorly wrung out. The article Checking the pressure switch of a washing machine describes how to get to this unit, remove and replace it.

As for the temperature sensor, in the case of its breakdown, the machine overheats the water, and sometimes it does not heat it at all.

In order to check the performance of the sensor, you must:

1. Remove the back cover of the washing machine and remove the sensor. It can be located both at the base of the heating element and on the tank.
2. We measure the resistance of the sensor with a multimeter.
3. We lower the sensor into hot water, give it time to warm up a little.
4. Measure the resistance of the sensor again.
5. We compare the obtained measurements: if they differ significantly, then the sensor is working, and if not, then we change it to a new one.

When disconnecting the terminals, mark them so that you can reconnect them correctly later.

If at one point the machine stopped draining water, then the search for the cause should begin with an inspection of the drain filter, hose, and then the drain pump. If debris and foreign objects get into the filter, the machine can not only stop draining water, but also not turn on. Therefore, before putting clothes and things in the drum, they inspect the pockets and remove all unnecessary.

Cleaning the drain filter should become a regular procedure, so you will save your machine from breakdown and yourself from spending on repairs. You can also clean the drain hose with your own hands, the maximum cost is two hours of time.

The pump in the Atlant washing machine is located, as in all machines, at the bottom. You can remove it from the housing through the bottom, laying the unit on its side. This process is the same as in Ariston, Beko, Samsung typewriters, we have described it more than once in articles on our website, for example, in an article about how to clean a washing machine drain pump.

As for the excessive intake of water in the tank, in this case it is necessary to check the water inlet valve. It is located on the back of the machine, in the upper part, from the outside, an inlet hose is connected to it. Therefore, in order to check and inspect the water inlet valve, it is necessary to disconnect the machine from the mains and from the water supply, then open the top case cover. Next, disconnect from the wire and check the resistance of the valve with a multimeter, it should be about 2-4 ohms. Otherwise, change the valve, for this:

• We remove all the hoses from the valve, opening the clamps, we notice their correct location.
• We unscrew the bolts holding the valve. If the valve is mounted on latches, then you need to unclench them.
• Turn the valve to the side and pull it out.
• We install the new unit according to the algorithm in the reverse order, the valve cannot be repaired.

One of the specific breakdowns of the Atlant washing machine is the failure of the electric motor. In most cases, the engine can be repaired without having to buy a new one. The fact is that the "weak link" in the engine are the brushes. But this work requires some skill, so we would recommend in this case to contact a specialist.

We follow the same advice in the case of a malfunction of the control board. The board is a complex microcircuit, which can be dealt with only with special equipment and tools. Based on the results of an accurate diagnosis, you can decide whether to change an expensive unit or still buy a new machine.

Even the most reliable equipment breaks down, and what can I say if the washing machine is assembled from Chinese components.However, in this case, the reasons for the breakdown of the automatic machine can be called:

• Wash water quality.
• Incorrect installation and connection of the machine.
• Operating conditions.

Summing up this article, we recall the basic rules that will help extend the life of your assistant:

1. Always check pockets for small items and debris.
2. Perform regular descaling.
3. Use softeners for hard water, such as a cleaning filter.
4. Rinse and clean the drain filter regularly.
5. Wipe the cuff and powder flask after each wash with a dry cloth to prevent mold from developing.

The Atlant company has long occupied its niche in the household appliances market. The Belarusian manufacturer is distinguished by a lower price of goods compared to European counterparts. This determines the buyer's choice in favor of Atlant. Atlant washing machines have an attractive design and modern technical characteristics, but they cannot boast of reliability and service life.

Therefore, the issue of repairing the Atlant washing machine eventually becomes relevant for owners. In the event of a serious breakdown, it is better to give the unit to the master, but the owner can handle some common problems with his own hands.

List of the most typical problems with Atlant washing machines:

• The machine does not turn on.
• The drum does not fill with water.
• The drum fills with water too slowly.
• The water does not heat up, the heating element is broken.
• Automatic stop of the washing machine during the cycle.
• The drum does not rotate.
• Drainage problems.
• Loud or unusual noise when washing or spinning.
• Strong vibration, spontaneous movement of the unit on the floor.

• The washing machine door does not open.

Consider the causes of breakdowns and options for their elimination in more detail.

If the display does not light up when you press the power button, check that the power cord is plugged into a wall outlet and that there is electricity in the house. If the matter is in the washing machine itself, then the troubleshooting options and how to fix them are as follows:

• Plug failure. Disassemble the plug and check the contact connections.
• Broken power cord. You need to ring the cord.
• Faulty electrical wiring in the car. Remove the outer panel of the unit and check the condition of the terminal clips, they may be oxidized.

If the display of the automatic machine reacted to turning on, the washing program was selected, and the machine does not work, the reason is as follows:

• Washing mode selected incorrectly.
• The door is not closed tightly enough. Check the integrity of the door seal, whether the item to be washed has got between the door and the body.
• No water enters the machine due to closed water supply taps.
• Timer defective. In this case, the washing mode of the selected program does not start due to a broken time relay. To check, turn the program selector until the drum begins to rotate. If this happens, then the timer is faulty and needs to be replaced.

First of all, check if the water supply taps are open. Next, make sure that the inlet hose is not deformed or clogged. Rinse it if necessary.

If the intake filter is clogged, perform the following manipulations:

• Close the water supply tap.
• Disconnect the hose from the unit inlet valve.
• Remove the filter and rinse thoroughly under running water.
• Install the valve, connect the hose and open the water supply valve.

If the intake valve breaks, it will need to be replaced. This can also be done by hand. It is necessary to remove the valve from the inlet pipes and replace it with a new one.

The water intake system is a weak point in Atlant cars. In good condition, when the water level in the drum rises, the water compresses the air in the pressure regulator compartment. When the pressure reaches the desired value, the switch is activated and the intake valve is closed. At the same time, power is supplied to the heating element and the switch for preventing premature opening of the drum door is activated.If the pipe is damaged or clogged, the water supply system will not work.

• Check how the tube is placed on the water level switch. If the end of the tube is hardened, cut it off a couple of centimeters and put it back on the switch.
• To check the operation of the switch, blow into the tube. You should hear the click of the switch.
• After, loosen the clamp on the hose, with which the pressure chamber is attached to the drum.
• Flush the chamber to keep the inlet and outlet ports clean and free of blockages. Inspect the chamber for cracks and deformations.
• Make sure the switch is working: check it with a multimeter. In case of breakage, replace with a new one.

The standard reasons that water is drawn into the washing machine slowly:

• Clogged or deformed inlet hose. In this case, flush the hose with water pressure.
• Inlet filter clogged. Remove and wash the filter.
• The water pressure in the system is not high enough. Make sure the water supply tap is fully open. If yes, then there is insufficient water pressure in the line. It needs to be raised. For example, equip a pressure tank under the ceiling of an apartment, or in the attic of a house. The minimum required pressure is 12 atm.

Causes of breakdowns and options for their elimination:

• Faulty water level regulator. A faulty water level switch does not recognize that the drum is full, so it does not turn on the heating element. Check the switch with a multimeter and, in case of malfunction, change it to a new one.
• Scale has formed on the heater. Due to the increased hardness of the water, lime deposits appear on the heating element, which affects the operation of the heater. Disassemble the washing machine and remove scale.
• Heating equipment failure. The heater contacts must be tightened and the oxidation cleaned. Using a multimeter, test the heating element for an open by first disconnecting one wire from the heater. If necessary, replace it with a new one.
• Thermostat failure. It serves to measure the temperature of the water in the tank of the washing machine and turn off the heating element when the desired temperature is reached. A malfunctioning thermostat switches off the heating element incorrectly: too early or too late.

If the washing machine stops on its own, during an incomplete wash cycle, check the power supply at the outlet using a multimeter. If everything is in order with the power supply, the reason for the stop may lie in the blockage of the inlet or outlet hose. Rinse the hose under a faucet to clear the blockage.

The next step is to remove and check the operation of the pump. It may be clogged or broken.

Next, check the health and cleanliness of the intake valve. If necessary, replace with a new one. Next, check the operation of the thermostat, heating element and timer. If the timer malfunctions, replace it with a new one, as repairs are too complicated for a non-specialist.

A typical case in the repair of the Atlant washing machine is the failure of the electric motor. The "weak link" in it is the brushes. Such repairs require special skills and it is better for the user to contact the service. The good news is that in most cases the engines are repairable and you won't need to buy a new one.

First, eliminate the simplest reason - a broken door latch. In the event of a faulty lock, the drum will not rotate. To check, press the door button several times, it may be stuck.

If the drum in the washing machine is not mounted on a direct drive to the engine, but on a pull belt, the belt may come off. Move the engine down a little and adjust the belt tension tighter. Be careful and don't overdo it. Too much tension on the belt will cause the bearings to wear quickly and break. When the belt is properly tensioned, when pressed, the belt will move about 12mm. If the washing machine is not equipped with a belt tensioner, the best alternative is to replace the belt with a new one.

Another possible reason for a drum stop is a broken motor. In this case, you should contact a specialist.

The first possible cause of water retention in the drum is a blockage in the outlet hose, or its deformation. Check the hose for blockage and flush if necessary. The exhaust filter may also be clogged. You can clean and replace it through the hole at the bottom of the washing machine.

The next possible cause is a clogged pump. Remove it and check for foreign objects. For this you should:

• Prepare a rag for water in advance.
• Remove the clamps securing the hoses to the pump. Check the hose for blockage.
• Use a pencil to check the rotation of the impeller. If the impeller rotates tightly, remove the chip with wires and mounting bolts from the pump. Then remove the clamps or unscrew the screws that connect the two parts of the pump.
• Mark or take a photo with your phone of their location so as not to be confused during assembly. Check the impeller chamber for debris, and also make sure that there are no threads wrapped around the shaft.
• Flush and assemble the pump. If the manipulations did not help, replace the pump with a new one.

If your washing machine suddenly makes a rattling noise or rattling sound while washing, you may have left coins, keys, or other foreign objects in your clothing pockets. If small metal objects from the drum get inside the tub, the washing machine may be severely damaged. Therefore, it is important to check pockets before washing.

Another cause of extraneous sounds may be a broken latch or door lock. The sound in this case will be buzzing, and will stop when the door is closed.

If a squealing sound appears when washing at high speeds, this indicates a slippage of the drive belt. Tighten the belt or replace with a new one

If you hear a crackling sound as the drum rotates, the drum bearing is broken and needs to be replaced.
