Why is the lock icon on the Samsung washing machine and how to fix it?

Operational errors, hard tap water, sudden surges in the power supply network lead to the fact that sooner or later the Samsung washing machine fails.

One of the signs of a malfunction of a household appliance is the flashing or constant glow of the lock indicator.

A detailed study of the question of what to do when the lock is on or flashing will help to quickly restore the washing machine to work.

The red light is flashing - what does it mean?

The indicator in the form of a key (lock) glows during the washing process - the washing machine is functioning normally and does not require repair.

At the end of the wash, after two to three minutes, the door is automatically unlocked and the indicator stops flashing or shining.

A different situation when the key or lock is on or flashing continuouslyeven when the wash process is over and the door is open. In this case, the washing machine does not respond to key presses (the light continues to glow red).

Such signs indicate that a breakdown has occurred and the washing machine requires detailed diagnostics and repair.

What's the first thing to do?

Before calling the master or starting to repair the washing machine yourself, it is necessary to check if the Child Lock function is activated (this is a special mode that blocks all the buttons of the device during washing).

If after restarting the Samsung washing machine, the lock indicator continues to flash, then it is necessary to carry out the following actions:

• disconnect the household appliance from the power supply;
• check the lock for foreign objects and debris (clean if necessary);
• restart the Samsung washing machine.

In a situation where, after the performed manipulations, the lock indicator remains on or blinking, it is necessary to conduct a more detailed diagnosis or contact the service technician for help.

What breakdowns can there be and how to fix them?

There may be several reasons why the lock image on the Samsung washing machine is on or flashing.

The hatch blocker is out of order

It is the hatch lock that sends the signal to the system module that the hatch door is closed and the washing process can be started. A malfunction of this element leads to the fact that the system does not receive a signal about a closed door, it blocks any processes of the washing machine.

The solution to the problem is to replace the hatch lock.

Algorithm of actions:

1. Open the washer door.
2. Using a Phillips screwdriver, unscrew the bolts securing the door lock.
3. Remove the outer clamp. To do this, carefully pry the part with a screwdriver.
4. By launching a hand between the body and the cuff, they take out the hatch locking device and disconnect it from the general wiring system.
5. To finally make sure that this element is malfunctioning, it is tested with a multimeter.
6. The defective UBL is replaced with a new one. The installation of a new element (it is important that the device corresponds to the model of the washing machine) is carried out in the reverse order of the dismantling process.

In order not to make a mistake when connecting a new interlock, before dismantling the old element, it is necessary to photograph all connections.

Faulty fluid pressure sensor

The situation when the lock indicator on the Samsung washing machine is on or flashing and at the same time the machine does not pick up or is constantly picking up and draining water, signals that the water level sensor (pressure switch) is out of order.

The thing is that water, filling the tank, increases the air pressure in the pressure switch tube. As soon as the pressure reaches the desired level, the contact closes and the sensor sends a signal to the module system to stop the water supply and start washing.

In order to dismantle the old sensor and install a new one, it is necessary to carry out a number of manipulations:

• unscrew the fixing screws from the back wall and remove the top cover of the washing machine;
• find a pressure switch on the front panel on the right side (looks like a washer);
• unscrew the fastening screws and disconnect the connectors;
• loosen the clamps with pliers and remove the pressure switch;
• making sure that the sensor is faulty (a multimeter will come to the rescue), it is replaced with a new one;
• all actions are carried out in the reverse order.

If you do not have a multimeter at hand, you can test the pressure switch using a tube commensurate with the diameter of the sensor hose. The tube is placed on the fitting and slowly blowing.

If the relay reacts to pressure, then two characteristic clicks can be heard... If no sounds are heard, the sensor requires replacement.

Burned out heating element

The lock indicator flashes, and the washing machine freezes during the washing process - most likely the heating element has burned out.

To dismantle, test and, if necessary, replace a given element with a new one, it is necessary to carry out the following actions:

1. Remove the drain filter, drain the residual water from the tank.
2. We remove the powder receptacle, unscrew the bolts securing the front panel.
3. Having picked it up with a thin screwdriver, remove the clamp. We wrap the rubber cuff inside the drum.
4. Dismantle the panel covering the trash filter. It is behind it that the bolts fixing the front panel are located (they must be unscrewed).
5. The heating element is located behind the front panel, under the tank. By testing the part with a multimeter, you can make sure of its malfunction.

Replacing a burnt out heating element takes place in the following sequence:

• in the center of the shank, unscrew the fixing nut;
• gently hit the hairpin with a hammer so that it falls inside;
• the part is pry off with a screwdriver and removed from the place;
• to get the heating element out of the groove, it must be carefully pulled by the contacts;
• the seal on the new part is lubricated with grease and a new heating element is installed instead of the old one;
• mount the temperature sensors in their original place and connect the wiring.

Before installing a new heating element, it will not be superfluous to clean the socket from which the old element was removed. Over time, dust, scale and dirt can accumulate in it, which significantly reduce the life of the heating element. Read more about buying and replacing heating elements here.

Master's call: where to find and how much will it cost?

When self-diagnostics and repairs did not lead to the desired result, professional masters will come to the rescue. You can call a specialist at home in several ways:

1. The easiest is to use word of mouth. Relatives, acquaintances, neighbors - everyone can recommend a master who once repaired a washing machine in their house.
2. Call a service technician. This method has one significant advantage - all work is documented. In the event of any controversial points, it is this document that will become evidence of the completed (or not completed) work.

In order not to face scammers, and to save not only money, but also household appliances, it is very important to take into account the following points:

• an honest master will never take money until the end of the repair (an exception may be a deposit for the purchase of an expensive part);
• a professional will always listen to the client, focusing on the brand of household appliances, duration and features of operation;
• an experienced foreman never calls the final cost of repairs without preliminary diagnostics (the amount may vary depending on the prices for new components, as well as the complexity of the work).
