I get DE and it won't work, thought it might be switch in door but now wondering if it is the load sensor

dE is a door error, check switch, door alignment and wiring harness

dE for LG does the spring of latch hook actuate? no> fix door latch Yes> is there clicking sound once or twice when the start/pause button is pressed to start the cycle? No> check door switch and main PWB Assemblyhope that helps..
OE is Drain Error.

Believe you are on right track would try door lock switch first easier to replace and most likely cause.

A DE Error Code is indicative of a "Door Error"

Check in this link the LG procedure: lgknowledgebase.com/kb/index

Hope helps.

try looking at the moisture sensor strips. usually inside the under the door area. two strips that sense moisture as the clothes roll by. these may be broke, shorted or need replaced?

dE: door error. open door. switch is out, clothes in door?

The only problem with this vehicle is that it needs a new window switch on the passenger side door.If the main switch on the drivers door works and the one on the door that the window won't go up on won't work it replace the switch on that door they all work on the same fuse.
