LG F4J6TMW0WW Washer Dryer - DE1 Error, now won't power on at all

[BrAinZ]

I have a 7 year old LG Washer/Dryer that locked up during a wash cycle with an error code of “DE1” (Door Lock issue). Turned off the power to remove wash load, but now machine won’t switch on at all. Checked obvious things like mains fuse and power, but won’t power up at all.

Model: W5J6AMOWW
Product Code: F4J6TMW0WWC.ABWQWUK

Looking (carefully) inside, there doesn't seem to be any fuses, other than in the mains power filter. Have checked that, but it seems good.

I can't see any main PCB circuit other than built into the display/control panel.

Does anyone have any experience with the LG machines?
Is it worth just buying a new display/control PCB to see if that's the issue?
(I don't seem to be able to source in the UK, but available via France.

Any help would be appreciated!

Hi. It's not a good idea to try speculatively replacing the pcb. They are expensive, and most people guess wrong when they suspect it. If the error code implicates the door lock, that's what needs looking at. However, error codes can sometimes just be wrong. If a door lock is faulty, it shouldn't cause the whole machine to go dead. It will stop it running, but you should still get power to the control panel. Unfortunately, it is difficult to fault-find these kinds of faults without having access to parts to try. It could be the pcb, but it could be something else or pcb and something else.

Thanks for the response.

I actually managed to get a local repair chap around today who didn't actually do anything other than saying it's probably the main PCB which apparently lives at the bottom of the LG Machine. He estimated that it would be around £300 for the main circuit board and that wouldn't actually guarantee to fix it.

I decided to just order a new machine so did that this afternoon. I actually went for another LG washer/dryer since this one had worked perfectly for 7 years without any blips at all..... er... until it completely died

As the current machine is being scrapped I decided to dismantle it to look for the main PCB. Found it and nothing obvious wrong. There appears to be two fuses on the board, tested the main one, seemed OK, the other smaller one is covered in resin so can't easily test.

Such a shame that we live in a world where it's commonplace to just scrap equipment like this, only good news was that LG are doing a "Trade-In" deal currently, so I did get £100 off

Hi. Yes, even most appliance repair engineers don't bother trying to fix faults like this. They just say it's the PCB and quote a very expensive price that no one would ever agree to. It's ludicrous that these pcbs aren't repaired. It's also highly unlikely the old one will fit in the new machine, either, as they constantly change them or make different ones for different models. Back in the 70s when I started repairing them, Hoover only had 2 different modules for every single washing machine they produced. They all also had the same pump, same valves, same door locks etc. etc.
