<<<The homeowner turned the machine on and tried to run a load of wash WITHOUT OPENING THE WATER VALVES??? Do you think there is a chance the HALL SENSOR BLEW OUT AGAIN due to no water entering the machine??>>>

************************

No. The "new" Hall Effect Sensors do not fail.

************************

<<<I unplugged  the machine and tried to run diagnostics. Machine reset and ran for a minute with the water valves now open but now it is not going into HIGH SPEED SPIN or won't even spin at all or Drum will not turn the least.>>>

***************************

Verify that the DRAIN MOTOR is functioning (draining *all* of the water).

Re-Verify that the HALL SENSOR is securely and correctly installed on the STATOR (all locking tabs should be snapped on).

At the rear of the washer---there's a short WIRE HARNESS---two plugs wrapped in a clear bag which runs/routes to the MOTOR and HALL SENSOR.

Turn on the washer.
Select the SPIN SPEED button to fastest spin speed setting.
Press the START button.
Move/wiggle the short-length WIRE HARNESS---if the Motor begins to spin---there's a "break" in one of the wires.
WIRE HARNESS : 6877ER1016B

If the tub does NOT spin at all---after moving the Wire Harness back and forth...

Turn off the washer.
Press and hold the SPIN SPEED and SOIL LEVEL buttons.
Press the POWER button and release all 3 buttons.
Wait for the door to lock (single click sound).
Press the START button 3 times---at one second intervals.
What is showing in the Display?
If the Display shows "0"----replace the MAIN BOARD.
A Serial Number is needed to order the *correct* MAIN BOARD.

John63, I envy all of your knowledge when it comes to lg. i thought I knew alot. In your last statement, if while in test mode on the 1st push of the start/play button and the display reads zero with a KNOWN good newer version hall sensor, the main pcb has failed. Am I correct that the zero should be reading tub speed? Usually 40-60 rpm? Any more juicy LG info?? Im authorized;)

Hi domain :)
I "jumped-on-board" with LG almost at the moment they entered the N.American market---and was very fortunate to have (in my opinion) one of the very best Training Engineers---Bob Albright (no longer at LG,unfortunately.)

At a time when *everyone* in all departments within LG were still "on a learning-curve"---Bob was a reliable/consistent source of *definitive answers* to just about *any* possible fault in an LG appliance (Thanks,Bob--if you're ever reading this).

**************************************

**************************************

After entering TEST MODE (and the door locks)---pressing the START *once* will (as I'm sure you know) initiate a test of the DRAIN MOTOR and the tub will tumble---at roughly 43-46 RPMs.

If the DRAIN MOTOR has energized (and is working) but the Display shows "0"...

I use the DMM---to verify power to the MOTOR (Stator) from the MAIN BOARD.

If the MAIN BOARD is "good"---the next area of focus---will be the HALL SENSOR (if the Serial Number is 805 or older)---then the WIRE HARNESS (faulty wire)---then the STATOR (cracked/damaged magnet(s) ).

I can pretty much diagnose any LG appliance within minutes;) been doing it for roughly 1.5 years. I love being one of the only techs who can work on LG! Sorry to thread jack!

I can relate :)

The important thing---is that once a tech becomes trained on LG products---it's unbelievably simple. Intuitive even.

Without "formal" training---and not knowing the "digital" aspect of LG products (and for that matter---any brand today)---is what makes most non-authorized techs frustrated.

Having done warranty for Frigidaire/Electrolux...Speed Queen...Samsung etc---I can confidently state that the quality of LG training (and enthusiasm overall) is without equal.

After 2007---many of those who've been with LG in those early days---are no longer there.
A victim of "belt-tightening"---which always originates at the corporate level of most any company.
Sad to see so many of those "pioneers" leave.
Nevertheless---there's still an atmosphere "esprit de corps" at LG.

Well I got into the machine tonight at the shop. Had dinner and was thinking about it after my last mouthful of Shrimp Scampi. Opened the back of the machine up. Tried to start a load at it was locked up. Fiddled around with the wiring of the stator and Hall Sensor and guess what?  Machine started up and ran through 2 cycles perfectly. Looks like the bad wire was in the wire harness. Now I have to start wiggling some wires around and get my trusty meter out to find what wire is causing my issue. (I'm kind of looking at the Blue wire) Let you know shortly!

After repairing the wire (if found)---install a new zip tie (nylon tie) at the base of the washer---but allow *some* slack.

My theory is that---once in a while---a factory assembly line worker over-tightens this zip-tie---leaving the harness too taut.
Over time one of the wires becomes pulled-apart internally---yet the wiring insulation appears undamaged.

Though not a common fault/problem---the few that I've seen---ended up being the *red* wire (broken apart).

John,


It turned out to be a bad wiring harness going to the hall sensor. Don't know if it was a ty wrap tightened too tight or cut in wire. But turned out I replaced harness and all is good.


Thank You!

Ok, you guys sound like you've been around the block with the LG's, so I'm going to start here. A few weeks ago I got the notorious LE code. After doing the typical unplug, rotate this way, rotate that way, plug back in...BEEP BEEP BEEP BEEP  >:( We replaced the Hall Sensor. It worked beautifully for 1 day. Two days after HS replacement I go to start a load of laundry...the dreaded LE code. So, I call the parts place where I got the sensor thinking maybe, just MAYBE, I got a bad sensor. New sensor comes in, we replace it, turn machine on....BEEP BEEP BEEP BEEP....UGHHHH  :tickedoff: Now hubby wants to replace Stator Assembly. All of the magnets look ok, nothing looks cracked. But, from what I'm reading, the issue I am having doesn't have anything to do with the SA. The drum will rotate both directions with no problem. I am not even getting a LITTLE resistance when I turn it. I just don't want to spend $150 JUST to prove a point that the SA isn't the problem! It's almost Christmas and that could be a few more gifts under the tree for the kiddos! ANY ideas???
