My LG Washer just started an result where it won't turn on when pressing the power button. Just if i unplug it for 10 seconds, then plug it dorsum in, it turns on. At that signal, i can plow it on and off, and it seems to exist working. i can besides so run a full bike.
In one case it turns off again, i have to practice the same thing to become it to run once more.
I don't even know where to start looking!
Thanks!

From what i have read so far, information technology appears it is probably the main control board?
LG Washing Machine Main Control Board EBR78263901
Can someone tell me how to troubleshoot this? how do i test the main control lath? I as well read somewhere it could be a stuck relay, but that post was non straight associated with my model.

The function showed upward, I was set to put it in.. but the car stopped having the result? Now it turns on every time like information technology used to..
I'yard going to hold on to the role for a fiddling bit and come across what happens. Is at that place something I can do to specifically troubleshoot the existing MCB and determine if its bad?

That's odd that information technology started working good again.
Yeah, I'd hold on to the role, as they say: If it happens once, Information technology will happen again!
Not that I'm aware of.

In the service manual in the mail y'all linked to... the pace before checking the MCB is "Are the PCB and noise filter connections cleaved or loose"
Is this a strictly visual thing? I oasis't opened the machine notwithstanding, but is this something that would crusade an MCB effect, so no upshot? does anything hither need to be checked for continuity?

It should exist simply a visual look/encounter.
Your talking most the racket filter checked for continuity? It should say in the service manual.
Just I have bad news, the line filter is No Longer Available: LG 6201EC1006Y Filter Assembly
So fifty-fifty if its bad, you lot can't order it.

Information technology looks like @t6man fixed information technology by replacing the MCB(Main Control Lath), he said its been working perfect for 2 weeks afterwards he replaced it.
@Louisew do you have the exact same model washer WM3470HVA ?

I have non changed the MCB. I take not had to.. (I ordered the MCB, then stopped having the issue, so i returned it.). I oasis't had this specific issue in a while. My worst issue and so far was with the door not locking, simply i replaced the switch in that location and haven't had any issues since..

yep this thread is old and then i'k having problem remembering. only i definitely did not accept to replace that. i recall specifically returning information technology. I don't know if the door switch might take caused cascading issues or not...
