LG WM2240CW dE code ( door error )

I have bought an lg wm2240cw unit used months ago, and it worked perfectly up until last week.
my house must have had a major power surge because some other appliances got damaged.

so as i wanted to do laundry, i selected spin cycle etc.. door switch tries to lock and unlock itself two times. then shows dE error code.
when the mechanism locks/unlocks, the door does in fact lock and unlock... so it appears to be working correctly, yet still get dE code.

I ordered a new door lock/switch from repairclinic, and it did not solve the error code. the switch itself looks different than the original one, but the wire adapter plugged right in. meaning its not original oem stuff, but does this even matter?

im thinking the main board might have some damage then ? all buttons appear to work.
i looked through the part list , and did not see any sensors that can be replaced that relate to door lock mechanism, it appears all is controlled by main control pcb
does this have anything to do with noise filter since it is power surge related ?
can i override a sensor to fool the washer ?

please help! thank you
