LG Washer won't start
When your LG washer won't start, first confirm that both the hot and cold water supply valves are fully open. The washer may not begin the cycle if it cannot fill. Next, check the user control and display board. If some buttons work while others do not, or the display is blank even though the board has power, the user interface board may be defective. The timer can also prevent an LG washing machine from starting, but it is frequently misdiagnosed. Test it for continuity using the wiring diagram before replacing it. Make sure the washer door or lid is completely closed, since the machine will not run when the door is open. If these checks do not identify the problem, test the line fuse with a multimeter. A blown fuse may indicate a shorted wire, motor, or drain pump, so correct the underlying issue before installing a new fuse. Whether your washer won't power on or has power but won't start, enter your model number to find the exact replacement part for your LG washing machine.

02 - LG Washing Machine User Control and Display Board
To determine if the user control and display board is defective, try pressing the buttons on the control panel. If some of the buttons work, but others do not work, the control and display board might need to be replaced. Additionally, if the display is not working, check the power to the user control and display board. If the user control and display board has power, but it isn’t working, replace it.

06 - LG Washing Machine Line Fuse
The line fuse blows if the washer circuits are overloaded. If the line fuse blows, the washer won’t start. To determine if the line fuse is at fault, use a multimeter to test it for continuity. If the fuse does not have continuity, replace it. In addition, you should investigate and resolve the problem that caused the fuse to blow. Check for shorted out components such as the wires, motor, or drain pump. If you don’t resolve the underlying issue, the new fuse will blow too.
