In Topic: LE error code on LG WM2487HWM - Main board failure?

24 April 2015 - 09:49 AM

Would someone post the LG Service Bulletin here, or if that is not possible,

summarize the contents?  Thanks!   Bob

 

Soldered connection(s) at the Stator failed (loose)

 

For reasons unknown to me---LG *does not* recommend repair (re-soldering)

It occurred to me that robeers is not able to access the password restricted lgtechassist website---and therefore is unable to see the image/photo of the fault with the STATOR.

 

As for the discussion on dielectric grease...

 

Here are the TDS for both:

http://www.2spi.com/...e-techdata.html

 

The info on dielectric grease (silicone grease) indicates that this type of grease can be used on battery terminals (tight connections) but is otherwise an excellent protector of electrical connections. Prevent high voltage leaks (spark plug wire for example). Keep moisture out etc etc

 

The info for the silver "impregnated" silicone grease---indicates that the product can be both a conductor---and---an insulator (silver content)

Better suited for improving connections---especially less than strong/tight connections.

<<< Beyond that, and before I replace the stator, the goal is to make sure I'm getting good solid connections. >>>

 

**********

 

My apologies---your washer has a defective STATOR and must be replaced.

 

The failed connection within the Stator is---per LG---not repairable.

 

All of the other discussion about improving electrical connections is *not* related to your washer fault.

<<< All greases work by the low viscosity allowing the grease to completely push out of areas with metal-to-metal contact. >>>

 

**********

 

True---if the electrical connections have high contact pressure.

 

While most of the connectors/plugs on an LG washer *do have* a tight/solid connection and are not prone to intermittent connection problems---the older/original THERMISTOR Plug connector is a weak link.

This is a good idea and one that was often recommended by an LG guru that used to frequent these pages. I actually forgot about this until you mentioned it. Go forth and conquer!

 

Yes---I did recommend using *dielectric* grease until I discovered that dielectric grease is an INSULATOR---not a CONDUCTOR.

 

I posted a thread awhile back---discussing this oft-misunderstood application/use of dielectric grease.

 

For an "LE" error---generally the LG washer does *not* have issues with weak/poor plug connections at the STATOR or MAIN BOARD.

 

It is far more common to have a weak feedback connection at the THERMISTOR on the older LG washers (such as the WM2487).

 

This triggers an error of "tE" (Thermistor *signal feedback* Error)

 

For this---using a silver-laced grease/compound at the Thermistor plug connection works exceptionally well (I use Chemtronics silver electrical paste)

 

On the WM2487 washer---if you are experiencing erratic "LE" errors---and the correct type and amount of laundry detergent is being used (as well as having already replaced the older syle Hall Sensor with the new and "stronger" sensor)---it's time to replace the STATOR.

 

Older models can have a problem with a degraded/weak connection at the Stator plug (not the Motor Wire Harness plug).
