The “Start” button in the washing machine does not work

The start button in the washing machine does not work Without a start button, the washing machine is completely inoperable. Meanwhile, this key is as vulnerable as it is necessary. The operation of the unit begins directly with interaction with it. If the button sticks, then you can still work with it, but what if not? Let's figure out what to do when the "Start" button in the washing machine does not turn on.

Why did this happen?

It is difficult to immediately figure out what caused the uncharacteristic behavior of the Start button. It could be a single system failure that can be fixed in just a couple of minutes, or serious technical problems. Try restarting the machine. If the problem is not resolved after this action, you will have to carry out a thorough diagnosis. The reasons for the failure may be the following factors:

problems with the surge protector;
the key itself is broken or the groove is clogged;
technical failure of the UBL or debris entering the lock, which leads to an erroneous reaction of the UBL;
problems with the control module board.

There is an LED circuit on the program selector, which in most cases is the cause of problems with the start button. LG machines especially suffer from this, since almost all of them are equipped with a selector, through which programs are selected. You can check your guesses and solve the problem yourself and quite quickly. For this:

start the machine;
Rotate the program wheel sequentially, pausing in front of each mode, checking that all the lights are on.

Attention! If at least one light bulb does not work, then the circuit is broken, and this is what led to the fact that the “Start” button does not respond to pressing.

This happens because the connection in the network is serial, and the signal goes from one light bulb to another. If the network is interrupted, the control module simply does not receive the command to start the wash, and the corresponding button does not work.

Troubleshooting

First of all, of course, it is necessary to disconnect the washing machine from all communications. It is also advisable to move it away from the wall or pull it out of the headset so that nothing blocks access to it or gets in the way.

Unscrew the bolts holding the top panel and remove it.
Remove the dispenser after loosening the screws.
Unclip the dashboard.
Remove the electronic board.
Find out which LED is burned out and disconnect it.
Instead of the old diode, you need to solder a new one.
Install the board and see if all the lights are on this time.
Proceed in reverse order and reinstall the washer.

You should not focus your attention only on this problem. Several factors can lead to interruptions in the Start button. Therefore, during work, at the same time, you can use a multimeter to check the surge protector and other buttons on the control panel, especially Start.

If the problem lies in the board, you won’t be able to repair it yourself, since this requires special equipment. You'll have to contact the master.
