LG Washer only goes Clockwise -- has LE error
« on: February 07, 2010, 10:44:55 AM »
i have a LG WM1832CW that is about 5 years old, this morning it gave the LE error and when i ran the diagnostics, the drum will spin clockwise, but not counterclockwise, when i run the CCW test the drum stutters in that direction mometarily and does not move further.

i checked the wiring, and nothing looks disconnected or broken

could it be the sensor that is causing the trouble?

there is no grinding or noise when it attempts to go CCW, only a very slight whirring noise.

thanks for the help!

Failed Hall Effect Sensor part number:  6501KW2002A

It's very,very important to use the correct type and amount of laundry detergent.

All front load washers require "HE" detergent (a low suds type detergent).

There are three commonly sold concentrations of HE type detegent.

HE : (2) Tablespoons Per Wash Load

HE 2X (double concentrated) : (1) Tablespoon

HE 3X (triple concentrated) : (1) Teaspoon

Most consumers follow the directions on the bottle or box of detergent--which is normally the correct thing to do. However, the amount recommended in nearly all brands of HE detergent are excessive & incorrect.
In older LG washers--the Hall Effect Sensor was prone to failing due the higher electrical load put on the resistor in the sensor during the spin cycle---from excessive suds in the washer.
A new Hall Effect Sensor has been introduced that has a higher tolerance against an increased electrical load from incorrect detergent useage.
Additionally---using the correct amount of HE detergent will end issues with:

1) Musty Odors

2) 'LE" Errors (that can cleared by unplugging the washer)

3) L-O-N-G cycle times (longer than time displayed).
    A 51 minute cycle can take 120 minutes to end.

4) Insuffificent Cleaning Results

5) Small water leaks behind the washer at the air vent.
    (Suds oozes out during the spin cycle)

6) Failing Hall Effect Sensors on older LG washers

It may be a bad Hall Sensor

click on picture


The Hall Effect sensor is easily removed and replaced.

You’ll have to remove the rotor and stator to access the sensor.

When replacing the rotor, you’ll probably need a helper to hold the drum in place when you push the rotor onto the shaft.

Otherwise, the drum may move forward enough to make replacing the bolt difficult.

The helper can also hold the drum from turning while you tighten the bolt.    

 

Before going to this trouble, check the connector on the main board.

It is the red connector closest to the heat sink.

Pull the connector off and verify the board is receiving a signal from the sensor.

It could also be an object jamming the tub. Turn it by hand and see if it moves free. Find the object and remove it. Small article of clothing etc.There might be something between the inner and outer tub. To get that out you remove the heater and fish out the object.
as shown on page 34

Just had the same issue and opened it up to find three wires in bad shape.
One was clearly cut and the other two had cuts through the insulation.
I reattached the cut wire (blue) and that seems to have fixed the issue.
I don't know how/why this is possible?
It really doesnt seem like that wire was ever in one piece and if it was what action could cause it be cut?
Thanks for everyone on this forum and your help!

If the wires were damaged at the bottom base of the washer (below the motor) this would be caused by excessive shaking of the wire loom during the spin cycle. Particularly on older LG washers on wood floors. This is not a common occurrence however--but I have seen this at least twice.

Thanks for the reply!
The damaged wires were all inside the door mid way up the bundle - embedded in the black sticky stuff.
That's why I don't see how they could have had anything 'cut' them or damage them in any way.
It seems more like they were damaged in the build and finally separated completely with the vibrations?
Great forum!!!

Wow just noticed that somehow I cross posted in the wrong forum.
Sorry for the confusion, this is supposed to be in the dishwasher thread about the LG LE error.

The sticky black tar causes this.

Every time that the dw door is opened & closed--wires that are stuck in the tar compound get stretched.

First the insulation on the wiring will become cracked and then the wires (usually the thin wires) will be pulled apart.

Repair any damaged wire(s) and wrap the entire loom from the plastic sheath at the bottom of the door up to the detergent dispenser assy. I add a small section of cardboard between the wires and the door as well.
Re-install the front cover and this will no longer cause problems.
New LG dishwashers use a cloth material instead of the tar-like substance.
