Samsung Washer won't start

If your Samsung washer won't start, first make sure both the hot and cold water supply valves are fully open. A Samsung washing machine won't start the cycle if it cannot fill. Next, check the user control and display board by pressing the control panel buttons. 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 cause a washer not starting, but it is often misdiagnosed, so test it for continuity using the wiring diagram before replacing it. Confirm that the washer door or lid is completely closed, since the machine will not run when the door is open. If these checks do not solve 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 problem before installing a new fuse. Enter your Samsung washer model number to find the exact replacement part for your specific washing machine.

06 - Samsung 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.
