Front Load Washer Won't Start
Is the power cord plugged in all the way?
Make sure there is power going into the machine. Plug the cord in the outlet directly, without using an extension cord.
Has the house circuit breaker tripped?
Check the circuit breaker or house fuse. If the circuit breaker has tripped, reset it. If it's a blown fuse, replace it.
Is the loading door shut completely?
The washer won't start if the door isn't closed tightly. Make sure the door isn't open.
Important: Unplug the washer from its power source before starting any inspection or repair work.
Just like top loaders, front load washers have a safety device in the form of a door switch. When the door is closed, the switch is depressed and signals that the door is closed and locked. The machine won't run without this switch. If the door is closed, but the machine still won't start, the door switch might be faulty.
To test the switch, you'll need a multimeter to test it for continuity. In order to access the switch, unplug the machine and then remove the front panel. The switch is located in the door frame or door lock assembly.
Similar to the door switch, the door lock signals to the washer that it's okay to start. The door lock must be engaged for the machine won't run. If the door switch tests okay, the next part to inspect is the door lock motor.
After unplugging the machine and removing the front panel, test the door lock motor for continuity with a multimeter.
On machines with a mechanical timer knob, the knob can get worn and no longer line up properly. You can try advancing the timer a little, and pulling it out again to try starting it.
If the machine has been running several loads continuously, it can overheat. When it does, it'll automatically stop working to protect itself from harm. Allow the motor to cool down, and then try again.
Newer machines are electronically controlled and have a control board. Diagnosing the control board is complicated, and repair/replacement is not recommended for a non-professional. It's also unlikely for a control board to go bad, so be sure to check all other possible causes before looking into this.
