My washer stopped suddenly and tripped the breaker. I flipped the breaker back on and there are no lights. Nothing happens when I press the start button. The breaker has not flipped off.

Phm for Model Number WM2277HW

ANSWER Hi. Remove the back of the control panel and visible see if it blew out a circuit on the board. It will be advantageous to find the supplied tech sheet inside the cabinet to aid you in the diagnosis. It allows you to put the unit in a diagnostic mode which brings up fault codes and tells you which circuit needs assistance. Use a volt/ohm meter part # TJMA-DM1 to assist you in your diagnostics. There are 2 boards. The Pcb Assembly,display Item Number: 6871ER2078A. Pcb Assembly,main Item Number: 6871ER1078T - Before ordering, please look at original board and contacts. LG uses two different boards and your model may use 6871ER1003C. The main board has a molded fuse on the board. Use the ohm meter on R x 1 scale to see if it is open. The diagnostic sheet will show the voltage input pins to check as well as the output voltage to the display board. Thank You.
