How to troubleshoot an LG front load washer with no display or power
LG washer power display troubleshoot
Remove the Top Cover of the washer.
Trace/follow the *plug* inside the washer---to the Electrical Noise Filter (6201EC1006L)
Pull off the *white* plug---use a test meter to check for 120V at the *white* plug (if no power---the fault is outside of the washer)
Re-connect the *white* plug back into the Noise Filter
Pull off the *pink* plug from the Noise Filter---test for 120V at the **Noise Filter** (NOT at the pink plug)
If no 120V at the Noise Filter---replace it.
If 120V is measured at the Noise Filter---replace the Main Board (EBR64144911)
