Check the house breaker or fuse for the washer electrical outlet. If the breaker is not tripped, verify that the outlet for the washer is working by plugging a small lamp or appliance into the outlet.

If the outlet is okay, I recommend that you

unplug the washer

and remove the top panel as shown in the third image below. Check the wiring connections on the control board that are traced in red. Check the wiring connections between the main control board and the display control board that are circled in blue. Carefully access the main control board and then plug the washer back in to check for a LED light that you should see on the control board. NOTE: Do not make contact with live wires or connections when you have the washer plugged in with the top panel off.

If the LED is not lit on the control board, I recommend that you

unplug the washer

and check the continuity of the wiring between the prongs on the outlet cord and the black and brown connections on the control board as shown in the first image. I do not recommend conducting a live voltage check as shown in the troubleshooting chart in the second image. If the board is apparently getting power through the black and brown wires traced in red and the LED is not lit, then the control board will need to be replaced. You will need to refer to your serial number to order the correct control board for this washer. Before serial number 608KW##00001 (608 indicates Aug. 2006, any date code after that would need the new board -- such as 702KW . . .), the part number for the control board will be 6871ER1003C. After that serial number, the control board part number will be 6871ER1078T. You can order this part from the

Sears PartsDirect

website. Be sure that you

unplug the washer

before accessing internal components. The procedure for replacing the control board is shown in the third image below.

If you replace the control board and still have a problem, you may also need to replace the user interface control board. The serial number will affect the part number on this component as well.

If you need more help, resubmit your question with additional details and the serial number of your washer.

If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website:
