Start button does not work on LG washing machine

If the Start button does not work on the LG washing machine, then you should not be surprised - this is the most vulnerable spot of the washer. Often, users of the machine encounter sticking and falling out of the key, which requires either a strong press or a complete replacement. Most often, it is not difficult to correct the situation: it is enough to clarify the nature of the problem and eliminate it. How to do this, we will describe in detail below.

What is the reason?

Immediately to say why the power button on the washers from LG does not respond to commands, it is impossible. The culprit may be a short-term glitch of the system, requiring a single reboot of the machine, and more serious problems. And if, after a short shutdown and restart, the situation has not changed, you will have to conduct a complete diagnosis. The Start button often fails due to the following issues:

LG washing machines are among the top three brands with often breaking Start buttons.

• interruptions with the surge protector;
• broken or dirty keys;
• erroneous operation of the hatch lock system;
• getting into the lock on the door of the trash hatch, which affects the UBL error;
• control board malfunction.

For problems with the Start button, you must first restart the machine.

On LG washers, in 90% of cases of a non-working start key, the LED circuit on the program enable selector is to blame. You can confirm the guess yourself, even without disassembling the washing machine. It is only necessary to adhere to the sequence of actions.

1. Run the machine.
2. Slowly rotate the program selector, checking whether the lamps in front of each mode are lit

Everything! If at least one LED does not light up, then the button does not work due to an interrupted circuit. The explanation is simple: the signal about the selected program is transmitted from one light bulb to another, and if a break occurs, washing is canceled. To restore balance, you have to replace the diode. Fortunately, everyone is able to make a replacement with their own hands and at home.

Machine repair

If the reason is clarified, then proceed to repair. We disconnect the washer from the mains, turn off the water and disconnect the machine from the sewer. It is recommended to immediately move the unit away from the wall or pull it out of the headset - then it will be more convenient to deal with the problem. Instructions on what to do are as follows:

• remove the top cover by unscrewing the two rear screws;
• loosen the screws on the front panel holding the tray;
• to get a powder receiver;
• snap off the dashboard;
• carefully remove the board;
• find and disconnect the burned out LED;
• solder a new one instead of the old one;
• return the board and make sure that all the lights are on;
• replace the panel, tray and cover in the reverse order.

In order to dispel doubts, it is possible to “break through” the network filter and the “Start” button with a multimeter during repairs. It is possible that several problems immediately led to the problem, so do not neglect the advanced diagnostics. It is not recommended to independently verify and repair the control board - fixing the module will require special equipment.
