Question about LG Washing Machines

Open Question

I have a LG washing machine model WF-SP950G having no power problem, after check on the AC input power cable connected to control board found AC voltage between 2 pin connector, brown and blue wires is 120V and voltage between brown on previous 2 pin connector and adjacence 1 pin connector blue wire is 230V. Plug in back the connectors to control board, no LED lit at all and no sound at all after press the ON/OFF button many times. Check on all components in the board are new and no visual defect or burn marks. Any suggestion for further troubleshooting?

SOURCE: pulled the wires for the crts off. didn't label them correctly help

Yes the first one near the rear of the set goes to the blue crt which if you are looking in from rear will be on the far left and the middle will go to green in the middle and the 3rd or last will go to red on the right. A rule of thumb in this case is alway red on right and green is always middle crt.

SOURCE: Does anyone know which connector to plug into on power supply

Double check all the connections from the AC line and from the power supply to the other circuit boards. The connectors you are mentioning are identical as per the picture below.
If you need a new power supply, you can find one from this link.

Lg wf-t1022tp gives a PE error code.


Try this first before replacing any parts or disassembling your LG washer:
- Unplug the washing machine for 1 minute.
- Plug the washing machine back into power.
- Restart the wash cycle.
- The washing machine may now have cleared the PE error code, if not see below...

You will need to check the wiring harness that connects the water level pressure sensor to the main control board.
- Check for a loose wire harness, a damaged wire harness, or a burnt faulty wire.
- Check that you get continuity through the wire harness by checking it with a multimeter.
- If the wire harness from the water level pressure sensor to the main control board is found to be faulty, replace it.
- If you get continuity and the wiring harness is securely connected to both the water level pressure sensor and the main control board, then proceed to the step below...

LG WASHER PE ERROR CODE - FIX METHOD #2

Lg washing machine wf-sp950g de ( door error )


Hi Azlan.
de Door Error usually shows when the door lock either won't undo...OR The machine won't start after the door is closed.
Both these situations probably mean that the door 'Interlock' is faulty.
The interlock is the part of the door lock which prevents you from opening the door while the machine is working.
It's part of the electrical circuit and should only be serviced by a qualified technician.
Good luck

Lg wf 801 won't fill


Yes , It can be related to the control board, but first of all please make sure that there is good water flows in both the inlets, check the flow after the valve , ensure that the inlet filters are not clogged and check all the connections from the harness to the valve and panel

I have a LG fuzzy logic the problem is that its not stopping the water input its over flowing ....


When you press the "SPIN SPEED" button and "SOIL LEVEL" button the water level frequency should be above 246. If the water frequency level fails to reach 246 in 8 minutes you will get an IE error or inlet error. You would need to check the water valve, water pressure, etc.
How does the machine know if the water level is complete? Water level switch right? So obviously the control is timing the amount of time it takes till the water level switch kicks off. If it takes more than 8 minutes we have a problem don't we? Therefore if something is partially blocking the tubing from tub to switch that might throw off the water level switch. It is located on the main control assembly and has the rubber tube connected to it. The control board uses this to determine water frequency level. Just blowing the sediment out of that tubing will cure the IE error IF everything else mentioned is all good. I meself would do that first before replacing any parts.

Dear expert of LG WF-F783PC (washing machine). i am using an LG washing machine model LG WF-F783PC.its giving a warning alarm after 3-5 seconds of operation (wash & spin mode)


Possible that the inlet flow is low , check the inlet valve and filter. Also try using the manual settings and if all the cycle works well then it is possible that the fault is with the controller unit or a possible errors from the level controller or the inlet valve.
It is best to remove them , check reset after cleaning.

Dead LG WF-T8016TP washing machine


Well I found the problem - fuse had blown.

There is a circuit diagram on the back of the washer that allowed me to locate the fuse. Take off the rear top plastic panel (behind the folding lid) by removing the two screws on the back. Inside close to the power cord you will find a fuse holder and an in-line ceramic fuse, 125V 12A. I checked mine for continuity and it had blown (as to why, I don't know yet - maybe the motor drew too much current with a large wash load?) - anyways, I replaced the fuse and everything works now!
