I have LG Washing machine ,Model 6.5 KG WF -7517TE Turbo Deluxe Top load .When push start button, Mechine just start and stop after a second, Displays "P E".What to do..????

DE is door lock error. Replace door lock.

The method we use on our LG WF 8071TTP top-loader:

Load stuff to be soaked.
Add soap.
Set load size and water inlets.
Start wash cycle.
Wait until water is full, and begins washing.
Press Start/Pause button.
Press Auto Stop button to switch machine off.

Next morning:
Press Auto Stop button to switch machine on.
Press Start/Pause button.
The fuzzy logic (if machine has this) will register that machine is full, and washing will continue.

I would call the washing machine engineer for a quote as there are to many things that can go wrong eric

Call LG's support line, they have excellent customer service.

I have a LG washing machine WTF655TH, it has stopped working, its full of water, but when you push the one button, it trips, how do i get it working again

Hi from retired Englishman in SW France,
'de' on LG's stands for Door Error. There is likely to be a problem with either the door solenoid/lock or the 'door closed' sensor. Both require a service engineer's attention I suggest ;-0(
Good luck,

i am using an LG washing machine model WF-N6861DN.its giving a warning alarm after 3-5 seconds of operation

Auto/off is power button--correct?
start/pause button actually starts the unit--correct?

This might be Lid cover open protection. There is a small magnet at the edge of the lid cover, housed in some sort of a catch.
If the plastic housing cracked, the magnet might have dropped into the washing drum. To overcome this, place a magnet on the position where the plastic catch will contact the washer when the lid is close.

most common is lint build up. a good hot wash with a good bleach...check your manual for manufacturer's recomendation. There's various products available..bleach is the most in-expensive and works well. make sure its set on high water level...pause machine for 10-20mins...let me know how you get on
