The washing machine door lock does not work. What to do if the washing machine does not close

Problems with closing the hatch in washing machines occur quite often. Fortunately, they can be easily fixed on your own. Usually this problem is divided into two. The first is when the washing machine door does not close, and the second is when the door in the washing machine does not lock. These two troubles are of a different nature and may be completely unrelated. Therefore, we will analyze them separately and tell you about them all. possible reasons and ways to eliminate them.

Washing machine door won't close

The first, most common problem with closing the door looks like this. You close the hatch, but it does not lock in the closed position (does not latch), or opens back. Or, you are trying to close the hatch, but it rests on something (something is stopping it) and cannot slam shut.

If the door does not close because something is blocking it and it does not slam shut completely, then the reasons may be the following:

• Door misalignment- this is a fairly common reason, which is caused by the fact that over time the door may have become slightly skewed. Check to see if the hook fits into the hole and if the door is warped. If the door is skewed, it must be adjusted using the fastening bolts.
• Tongue skew– if you checked the door level and it turned out to be in order, then the second reason may be the skew of the fixing tongue itself. The tongue is held in place by a metal rod that may have fallen out. As a result, the tongue is skewed and does not perform its function. In this case, you need to disassemble the door and insert the pin into place. If a hook or other part breaks, then it is necessary to replace the washing machine door handle.

If the door closes all the way, but does not latch or lock, then the cause may be wear on the plastic guide, which is installed on some models of washing machines (Candy, Indesit, etc.). Over time, the washing machine door may become slightly warped without you even noticing it. But this guide will begin to wear out and eventually the hook will no longer be fixed in the groove, which is why the hatch in the washing machine will not close. IN in this case This guide needs to be replaced.

The hatch in the washing machine is not blocked

If the door closes properly, it latches, but when the program starts, the washing machine does not turn on and does not start washing because the hatch is not locked. Then there is a high probability that the problem is with the locking device or, in extreme cases, with the control module. But let's take it in order, the reasons may be as follows.

The first and most obvious reason for the door not locking is breakdown of the hatch locking device (UBL). The UBL is triggered and blocks the door before the wash starts, when voltage is applied to it. If, when current is supplied to it, blocking does not occur, then the UBL is faulty and requires replacement, and how to do this yourself, read in our article “Checking and changing the UBL of the washing machine.” In the video at the end of the article, you can see how to replace the washing machine door lock.

This malfunction is the most obvious and most common. To make sure that the lock is not working, ring it

The next reason may be that UBL could be clogged. There are rare cases of small debris or things getting into the opening of the washing machine lock. The likelihood of this increases if you have small children in the house, they could push some object into the blocking hole. In order to determine whether the lock is clogged, it is necessary to visually inspect it and, if necessary, remove and clean it.

The most unpleasant reason when the door does not lock is broken electronic control module. If the required signal does not arrive from the module to the UBL, then blocking does not occur. In this case, you cannot do without calling a washing machine repair specialist. The reason could be either a burnt-out module or a lost software his. In the first case, the module requires replacement, and in the second, you can get by with flashing it.

The washing machine door does not close, usually due to defects caused by mechanical impact. At the same time, the door lock does not make a characteristic click.

Difficulties with blocking are caused by malfunctions electronic component unit. In this case, the lock slams shut, as expected, until it clicks. However, there is no second click to confirm electronic locking. As a rule, the device displays information with an error code on the display.

External damage

The lock may not close due to normal wear and tear or rough handling. For example, sometimes wet things are hung on the door, which with their weight can damage the mechanism. Damage may also occur if the unit is closed with excessive force.

The device may not close for several reasons:

1. As a result of prolonged use, the washing machine door was warped.
2. The locking tab in the lock mechanism was misaligned.
3. The plastic element or rubber gasket has worn out.

Identifying this type of fault is not difficult. To check, you can perform a test closure in normal mode, without loading laundry. If the door does not close under such conditions, it means the lock is broken or the fastening is skewed. Sometimes this may be due to incorrect installation and then in an uneven position, the hatch can warp under the influence of weight and vibration. How to install washing machine That's right - read.

You can debug the operation of the machine on our own. Carefully inspect the device and locking mechanism. Check:

• Are there any objects preventing it from closing? Sometimes things can completely or partially fall under the hatch and jam the system.
• Condition of the locking hook: does it fit into the groove?
• Is the locking tab in place properly?
• Signs of peeling of plastic or rubber gasket.

Warping usually occurs as a result of prolonged use. This can be easily determined by checking how stable it is. If the guide has undergone significant wear, the hook will not be firmly secured in the groove.

Internal problems

If there are no difficulties with slamming the lock, but it does not lock electronically door in the washing machine you are using, and the washing program does not start, then the problem lies inside the device itself:

1. Out of order hatch blocking device(UBL). The unit should always be electronically locked as a safety precaution to protect users and the room in which the unit is operated. This provides protection against flooding. The UBL, which contains bimetallic plates, is responsible for these actions. Over time, they become deformed and worn out as a result of exposure electric current. In this case, blocking will not occur. The element needs to be replaced.

1. Small particles got into the UBL hole foreign object. It could be debris, lint or threads. For diagnosis, it is necessary to inspect the UBL, disassemble and remove foreign elements.

1. Could have broken. This means that the UBL does not receive the correct signal from the control module to lock the hatch, so the washing machine door does not close. This reason is mainly due to burnout of contacts or a general program failure, for example, associated with voltage surges. The control module needs to be diagnosed. Depending on the results obtained and the nature of the damage, reprogramming, repair or replacement of the door lock control module in the faulty washing machine is required.

Basically, UBL problems are eliminated by replacing it.

Diagnosis and treatment

Is it possible to do it yourself if there are problems with the lock? In some cases, it is possible to cope with this task on your own. First of all, it depends on the nature of the malfunction and your vocational training. If the breakdown consists only of mechanical damage or jamming of the lock by a small foreign object, then if you wish and have a screwdriver, you can easily resolve it. So it is possible . However, it is better not to try to fix electronic damage associated with UBL yourself.

Repairing the control board requires qualifications, experience and dexterity.

Unsuccessful attempts to get a blowtorch into electronic board controls will make repair impossible, and then the element will need to be replaced. And this will result in a significant amount of repairs.

Conclusion

If the lock does not close or the door of your washing machine does not lock, then the first step is to carry out an external inspection. Quite often problems have mechanical character. To avoid similar problems, you should treat equipment and its mechanisms with care. The second type of malfunction is associated with the electronic module that programs the hatch lock. Typically, the device warns about such an error using special code. Such a breakdown is much more serious and more expensive.

The opposite situation also happens: . Here, too, mechanical damage can act as provoking factors. however, more often it is an electronic failure. If the electronic module breaks down, it is better not to try to fix the breakdown on your own, as you can only make the situation worse. You should definitely contact specialists.

Even the most expensive Appliances not protected from periodic breakdowns. If your washing machine does not block the door, then it is no longer possible to start washing on it. You will learn what to do in this situation and how to get rid of the problem by reading our article.

1. The lock handle on the hatch door is broken. This happens mainly after many years of use. The lock is a rather fragile mechanism and over time it simply wears out. Careless handling can also damage it. Do not slam the door sharply and hang wet clothes on it after washing.
2. The hinge on which the door hangs is skewed. Foreign objects getting into the hole between the door and the wall is one of the reasons. Also, the “oblique” loop appears due to the purchase of cheap components.
3. The locking tab on the handle is deformed. Due to strong pressure on the washing machine door, the metal rod may become deformed, causing the door to stop locking.
4. The guide blocking the hatch has moved. Last possible mechanical damage. The guide is a plastic object that wears out during long-term use or poor raw materials.
5. The hatch locking device (UBL) is faulty. The operating principle of the UBL is as follows: the device is supplied D.C. during the washing process and it functions. In the event of sudden surges in electrical voltage or extreme temperatures, the UBL may fail.
6. A foreign object got into the UBL. It all depends on the conscientiousness of the user. Regular diagnostics and cleaning of machine elements will prevent the ingress of extra items. Otherwise, blockages will form and components will not function, including the UBL.
7. The control unit does not work. This is one of the most complex elements of a washing machine. There can be quite a lot of factors for its incapacity: a sudden power outage, a change in temperature or electricity, high humidity, etc.

The lock handle on the hatch door is broken

The washing machine has turned off, the user decides to take out the laundry, but the handle suddenly breaks and the door does not open. Trying to open the door by force can lead to even worse consequences. It is better to use the “emergency door opening” (if such a function is available), a lock or tools.

What to do?

You should buy a new handle and install it after removing the old one, this can be done as follows:

1. Remove the door from the front mountings using a screwdriver.
2. Next, unscrew all the bolts around the perimeter and disconnect the halves of the structure
3. Pry up the glass and remove it
4. After this, you should remove the metal rod on which the handle is held. To do this, you need to push a nail or other thin object into the bolt and carefully pry it off.
5. After removing the handle and its components, install a new one, performing all the described steps in reverse order.

The hinge on which the door hangs is skewed

If the washing machine door does not close due to the locking hinge, then you cannot do without replacing the part. First you need to check the degree of fixation of the main elements. If the damage is minor, the door can be simply adjusted.

How to fix it yourself?

Replacing the hinge is quite simple. The first step is to remove the hatch from its hinges and completely disassemble it, but in some models you can do without this. We unscrew the screws that connect the glass and plastic halves. Then, apply a little pressure on the elements to separate them, the main thing is not to overdo it, as you can break the door.

After detaching the plastic halves, you can begin installing a new hinge. After inserting it into the desired slot, achieve a characteristic click by pressing the halves tightly against the loop. Next, all steps are performed in reverse order. To do everything correctly, it is recommended to take photographs at each stage of the work.

The locking tab on the handle has moved

The tongue on the handle is designed to fix the door using a plastic guide. The element is quite thin, and therefore is one of weak points unit. If no defects are found on the door, but the washing machine hatch is still blocked, the fault is probably due to displacement or wear of the metal rod.

What to do?

First you need to determine the condition of the tongue itself. To do this, we completely disassemble the unit door, unscrewing all the bolts. At best, the metal rod can simply be adjusted to fit into the desired position. This will allow the tongue to function normally again. If the tongue itself is damaged, you will have to completely replace the door handle.

The guide that is responsible for blocking the hatch has become deformed.

If there are any problems with the plastic guide, then it becomes physically impossible to close the hatch, and the user will not be able to start washing. Plastic elements are quite brittle in their structure and can wear out or sag during prolonged use.

How to fix it yourself?

The part cannot be repaired; a new plastic support must be installed. The first thing to do is remove the old cuff. In most cases, you will need to remove part of the housing. It is important to make sure that the new part is no different from the old one. Afterwards, we remove the plastic clamps by pulling the connecting latches towards ourselves, having first unscrewed the screw. Before installing a new plastic guide, it is recommended to clean the entire surface of dirt.

The hatch locking device (UBL) is faulty

UBL is designed to fix the hatch in the closed position during the supply of electricity. Electronic device signals main computer that all contacts are secured and washing can begin. After finishing work and disconnecting from the power, about 3 minutes pass before the latch disengages and the door can be opened.

UBL usually breaks due to wear of the plates after prolonged use, or their destruction during extreme operation of the device (voltage or temperature surge).

The plates take a deformed position, and the door does not open after washing, the UBL remains blocked. If the washing machine does not lock the door before operation, then the problem may be the same.

Replace the door lock yourself

To replace the UBL, open the hatch. If it is blocked, then do the following:

1. Pull out the top cover
2. We place the washing machine on its side (so that it stands on two legs), this will allow the tank to move away from the front
3. We put our hand in and take out the locking device
4. We look for the latch and move it to the side. Ready

Next, you need to remove the cuff by loosening the clamp that secures it. This is done with pliers or a screwdriver. We remove the cuff and unscrew the two bolts that are located next to the hook of the UBL lock. All that remains is to disconnect the wires, pull out the UBL and install a new device. Carefully put on the cuff and secure the structure with screws.

A foreign object got into the UBL

The UBL works together with a heating resistor and its resistance increases with increasing temperature. This leads to a change in the shape of the plates and their displacement. The lever connects the contacts of the latch and the plastic guide. This creates a fixation for the hatch door. When the power is cut off, the temperature drops, the resistor cools, and the contacts return to their normal position. If any debris gets into the UBL, this can lead to a malfunction of the device.

What to do?

To remove interfering elements, there is nothing left to do but disassemble the device. This is not difficult. IN previous problem We have already described the process of withdrawing UBL, everything is the same here. We completely remove the blocker and inspect it for debris. It is necessary to clean not only the mechanism itself, but also the hole where it is installed.

The control unit is faulty

This is one of the most important elements of any modern washing machine. The control unit controls and synchronizes the operation of all electronic elements and mechanisms. A malfunction of the control board can lead to any problems in the washing machine, including the answer to the question, why doesn't the door lock?. A breakdown can be caused by a technical defect, water getting on the electronics, a sudden shutdown or a voltage drop.

First you need to make sure whether the board can be repaired or needs replacement. There is no way to do this without opening the block. The most expensive cars have a built-in self-diagnosis function, which makes life much easier and helps identify the problem in most cases.

To correctly identify the item of damage, you cannot do without the help of a professional specialist. Self-diagnosis risks leading to incorrect conclusions. You can conduct a test yourself with a multimeter and visually inspect the device. The wiring may be burnt or there are burnt areas on the board. All this indicates the need for replacement.

If nothing of the sort is noticed, the control unit may still be salvageable. To do this, it is better to call a specialist if communication skills with such equipment are not enough. He has at his disposal a complete diagram of the block and the machine as a whole, and special software will help to understand the exact reason. Only a deep analysis will help make high-quality repairs, because working with electronic board– this is a very complex process.

Have you loaded the laundry into the drum and are trying to slam the door, but it won’t close? What happened: the lock does not work or the latch does not fit into the loop? There may be several reasons: from trivial problems to breakdowns requiring repair.

If your washing machine does not close the door, check self-diagnosis and fix the problem.

Why doesn't the hatch door latch? The reasons are divided into two categories: mechanical and electronic.

If there are mechanical problems, you will not be able to close the door at all; it simply will not lock. This happens because:

If problems arise with the electronic locking, the hatch will close mechanically normally. But you will not hear a characteristic click, water will not be poured into the tank.

In case of such breakdowns, an error appears on the display that the door is not closed.

Why the lock does not turn on:

How to fix the situation

If the door does not close tightly, and after inspection you find that the tongue or guide is misaligned, you need to replace it.

What should I do if the SMA display says that the door is not closed? Means, electronic lock does not work. Indicators on mechanical panels may flash. The UBL device needs to be replaced.

• Open the hatch door and unscrew the two bolts securing the device.
• Bend back the sealing rubber.
• Remove the clamp and tuck the cuff inside the drum.
• Take out the UBL device and disconnect the wiring from it.

Inspect the wiring. If burnt parts are visible, it needs to be replaced. The UBL is checked for resistance with a multimeter. If the lock is faulty, replace it in reverse order.

How to solve problems with the electronic module

You figured out the lock of the washing machine, inspected it, and found no damage. How to determine that the cause of the malfunction is in the module:

1. The door blocks, but does not erase.
2. The “Lock” indicator does not light up on the display.

If any element or triac of the module burns out, then any part of the washing machine may fail. For example, a UBL may work properly, but the control unit does not recognize its signals. Or the triac of the fill valve is faulty, so water intake does not start.

Carefully inspect the board and its wiring at the time of scorching. Let's look at how to get to the module, but it is not recommended to repair it yourself.

If you do not see any signs of damage, take the board to service center. There will be held professional diagnostics and repairs.

As you can see, some breakdowns can be repaired yourself. But there are situations when you cannot do without a specialist - do not take risks and entrust complex repairs to specialists.

All modern models washing machines are equipped with a function automatic locking hatch, which is activated immediately after the washing program starts. A locked door cannot be opened without pausing the machine. This is designed for safety reasons: automatic locking prevents flooding due to a loose door, and also protects against accidental discovery hatch (for example, small children).

If there is a breakdown with the hatch, as a result of which it does not lock, the washing machine will not start washing. Why this happens and how to solve it this problem, you will learn from our article.

Types of breakdowns

All the reasons why the automatic locking function may fail are divided into two large groups. The first group includes mechanical breakdowns, and to the second - problems with electronics.

Let's consider each of the possible types of breakdowns in more detail.

Type of failure	Cause of failure
Mechanical damage
The lock handle on the hatch is broken	Most often, this happens after several years of active use of the washing machine - in this case, the fragile lock mechanism simply wears out. Also, the handle may break due to heavy items being hung on the door to dry.
The hinge on which the door hangs is skewed	The reason for this may be low-quality components. Also, misalignment can occur due to something getting into the gap between the door and the wall of the washing machine.
The locking tab on the handle has moved	The door may not close due to the fact that the rod (metal rod) that holds the lock latch in a certain position has moved. This usually happens when there is too much pressure on the door.
The guide that is responsible for blocking the hatch has become deformed.	If the door can be closed, but you do not hear a clicking sound, the plastic guide is most likely worn or bent. This happens as a result of active use of the washing machine or due to low-quality raw materials.
Electronics problems
The hatch locking device (UBL) is faulty	The UBL is activated under the influence of voltage, which is supplied to it from the moment the wash begins and until its end. Over time, under the influence high temperature, the metal elements of the device may become deformed. This is especially facilitated by changes in network voltage.
A foreign object got into the UBL	If you neglect to regularly clean the washing machine, detergent residues, small debris, lime particles, threads, buttons, etc. can accumulate, forming blockages in various places of the device, including in the UBL.
The control unit is faulty	The electronic module of a washing machine is a rather complex device that can fail under the influence of a variety of factors. Most often this occurs due to a sudden power outage or power surge.

Watch the video tutorial that shows how to disassemble the hatch locking device if an object has fallen into it.

How to replace the hatch handle?

If the damage to the hatch handle is quite serious, the easiest way would be to replace the entire mechanism rather than go through every part. First you need to pull out the broken handle.

This is done in the following sequence:

• disconnect the washing machine from the network;
• remove the door from its hinges;
• unscrew the bolts connecting the two halves of the hatch;
• carefully separate the halves;
• remove the glass part and photograph the location of all elements;
• carefully pull out the metal pin that secures the handle;
• remove the plastic handle, then disconnect the return spring and hook.

Now that the old part has been removed, you need to replace it with a new one.

To do this, we take the following steps:

• We carefully study the photograph, which shows the original arrangement of the elements;
• install on old place spring and hook;
• insert the pin into the first hole;
• holding the pin and spring with one hand, put the handle in place with the other (the pin should pass through it);
• insert the other end of the pin into the opposite hole;
• we check the correct location of the parts: the spring should slightly tilt the handle to the side;
• We assemble the door and return it to its place.

To see the entire process of disassembling the door, see the following video.
