If your washer is completely unresponsive, start by ruling out the obvious--is it unplugged? Did the circuit trip? To test whether the electrical outlet is the problem, plug a hair dryer or other electrical device into it. If the hair dryer doesn't work, the wiring in the outlet is the problem. Have an electrician repair the electrical outlet.
If the hair dryer works, there could be a wiring problem in the washer. Follow these steps to check wiring in the washing machine:
Unplug the washer and check the power cord for damage. Replace the power cord if it's damaged.
Check the wiring connections on the timer or main control board. Reconnect any loose wires.
If your washer has a digital display, check the wiring connections between the main control board and the user interface board. Reconnect any loose user interface wires.
If the wiring connections are okay, you may need to replace the main control board or the user interface board. We recommend that you have a service technician test the washing machine control board and user interface board or the washer timer before replacing control components. Testing the controls typically requires live voltage checks. We don't recommend that you perform live voltage check on your washer yourself because those tests are dangerous.
