LG washing machine does not switch modes

LG washing machine does not switch modes What to do if a properly functioning automatic machine only yesterday does not switch washing modes today? All the indicators around the selector are lit as if in test mode, and you can’t select the desired program? Let's figure out which part failure can lead to this problem.

Let's look at the control board

First of all, you need to carefully inspect the LG washing machine. By studying the “symptoms” of the problem, you can make the correct “diagnosis”. Turn on the machine and watch the programmer. Find out if all the lights around it are lit or if any indicators are off. It is very important.

If the machine does not change programs, while some or even all of the LEDs around the selector remain extinguished, they may have burned out. To “cure” the washing machine, it will be enough to replace the failed indicators.

All selector LEDs on the control board are combined into a circuit, and if one indicator burns out, the others also stop working.

You can talk about another breakdown when all the programmer lights are on. If all the lights around the selector are illuminated, there is a good chance that the microcontroller port line is faulty. To check the semiconductor element you will have to arm yourself with a multimeter. Based on the diagnostic results, a decision is made to replace the triac. LG CM module

Sometimes the LG washing machine does not switch programs not at all because of the control board. A similar symptom can be produced by a completely different part, which at first glance has nothing to do with the programmer. This type of error is caused by the heating element. Let's figure out how to check and replace the heating element.

Checking and changing the heating element

If the automatic machine does not switch washing modes, and everything is in order with the control module, it is worth checking the tubular heater. Oddly enough, but it is a broken heating element that can provoke the problem. Getting to the element on LG front cameras is quite simple. The algorithm of actions will be as follows:

turn off the power to the LG washing machine;
move the machine away from the wall to have free access to its rear part;
disconnect equipment from communications;
Unscrew a couple of bolts holding the washer cover;
remove the top panel;
remove the screws around the perimeter of the back wall, remove it and set it aside.

The heating element for ElG front cameras is installed directly under the tank.

Having found the heating element, you need to check it with a multimeter. Reset the wiring (after photographing the connection diagram) and attach the tester probes to the contacts of the heating element. Normally, the device display should display a value within 25-35 Ohms. Otherwise, we can talk about a faulty part and the need to replace it. Let's carefully check the heating element with a multimeter

To replace the heating element on an LG washing machine, you must:

disconnect all wires from the element;
unscrew the central nut of the heating element;
“drive” the bolt into the hole;
pick up the base of the tubular heater with a screwdriver and pull out the part;
clean the “nest” of debris and dirt;
take a new heating element and connect a temperature sensor to it (the thermostat must be removed from the old heater);
insert the new heating element into the “socket”;
secure the heating element with a bolt and nut;
connect the wires to the element, focusing on the photo taken earlier;
Assemble the machine body by replacing the back and top panels.

After this, the LG washing machine can be put back and connected to the communications.Launch the “home assistant” - the problem with choosing washing modes should disappear. If this does not help, in-depth diagnostics of the control board will be required.
