LG LE error code - Stator/Windings test

[roodog]

Up front, I am new to this work as will be obvious below, but am a keen learner.

I tested the rotor for continuity and all combinations came back with .01-.02 Ohms (not the "1" which would indicate an open circuit?).

It says it should register 5-15? Is it strange that ALL cont would be lost? Is there any way to test the windings? there is no obvious damage, but would I see it if there were? is this rotor/windings repairable? this is still under the 7 year motor warranty, but I live in rural NH which means I do not have an LG appl tech within 50 miles. LG says they wont send parts to public, but another forum poster said they will? what is your advice? appreciate in advance.

thanks

notes:
Hall sensor failure:
When too much of the low-sudsing HE detergent is used in the LG washers (and especially non-HE type detergent)...

The motor & main board will detect suds when the tub begins to spin.

As strange as this sounds--suds causes drag/resistance.

The older hall sensors overheated--the main board would shut-down the washer & flash an error message of "LE".

If the Hall Sensor was not damaged--then the customer would be able to unplug the washer for about 2-3 minutes and plug in the washer again--the washer would be able to be re-started (reboot of the computer).

Eventually--this results in an "LE" error that won't re-set and the Hall Sensor needs to be replaced. The tell-tale symptom of this (aside from a "stuck" LE error) is that when the customer pushes the START button--the tub *wiggles* momentarily before flashing LE again.
On a few occassions--the washer WILL start but the motor GROWLS loudly.

Problem:
An occasional LE error but always a slow or no spin: Solution:
The Red wire going to the Hall sensor was intermittent. You can test this from the main board connector down to the connector on the hall sensor by checking continuity.  There is an intermediate connector down by the motor/hall sensor so you can isolate the problem even more. My problem was in the short wire harness that connects directly to the motor and hall sensor.  I could not find the open point of the wire so I added a new red wire and integrated it into the harness.  All is Good!!!

JW thanks....but I have tried the reset and drum "stutters" and tries to turn but does not....after a few minutes it shows as LE...I have tested all parts of the flow chart and the only problem is the Stator continuity comes back as bad. I think I am past changing the detergent amount, although this may have caused the problem.

how do you tell if the stator/windings are "bad"? all elsechecked out.

Post yer model number

WM2277 service manual
 
page 30 says 5 to 15 ohms should be the reading between all of the stator terminals

thanks JW, any advice on how to get LG to send a warranty replacement part to a civilian?

Talk to LG customer service and ask to speak to their supervisor.  You can explain the situation to them and they should address it.  If that doesn't help, ask to speak to higher level supervisor.

Good luck.

... tested the rotor for continuity and all combinations came back with .01-.02 Ohms
... It says it should register 5-15?

using a "digital" OHM meter?
should be using the 200 OHM scale

[roodog]

wow....what a newbie mistake...I had it on 20k..thanks RegUS.....so that leaves the Hall Sensor....is there any way to test the sensor attached to the stator?....(just wrote to LG, so I will have to send a retraction)

thanks JW, I went back to the drawing board....tested Hall Sensor and....

(1) not getting any cont. on White/Red and White/Blue...so the Hall Sensor is gone as well?.....and...

(2) did the QC test for low drum spin (IF81) and first time it groaned, second time, nothing....test voltage output with just power on (nothing...expected?), then tested in QC test mode...still nothing?

does this mean the power board is faulty.....any double check of this, just so I know I'm not making another rookie mistake?

when testing voltage on motor assembly, did not want to stick probes too close to anything hot, so tested the connectors near base of machine (not where they connect to the stator) THEN went back up and tried PWB motor output....nothing

sorry to be a pain (again)...but hey, I'm learning a lot (like beg a technician to come out of their house-call range)

[roodog]

anyone have any theories on my previous post?

Replace the hall sensor, part # 6501KW2002A
