<<<So the expected lifetime is more than 10 years?>>>
This is a tough one to answer accurately for several reasons...
1) LG entered the North American market in 2003---coming up on 10 years.
2) All LG washers built *before* November 2008---did NOT have "True Balance" (anti-vibration technology).
Consumers with *concrete* floor laundry rooms---did *not* have issues/complaints with moderate-to-severe vibration/noise during the spin cycle---and were otherwise generally satisfied with their purchase.
Owners with pre-2008 LG washers---on a *wood* floor not only tended to be unhappy with the spin cycle noise/shake---but typically experienced Tub Bearing/Trunnion failure at an earlier/faster rate than those with the washers on *concrete* flooring (higher-than-normal bearing stress).
3) Beginning 2008...
LG washer Bearings were changed (larger).
Hall Effect Sensor was (rotor position sensor) improved---larger resistor
The Rotor (part of the motor assy) was strengthened (steel splines vs plastic spline)
Recently---the internal/inside of the Outer Tub Assy was re-designed. The bracing/lattice-work type ribbing on the tub (for rigidity) was switched from being on the *inside* to the *outside*.
This allowed for a smooth surface area inside the tub---to eliminate pockets/holes/crevices---that could allow for scum accumulation/build-up.
Suspension Struts were improved
A new drain hole was added to the Door Gasket (6 oclock position) to allow water from the gasket to drain back into the tub
Various software changes occurred (mostly to improve wash results)
Thermistor design was changed---virtually eliminating those "tE" errors (nuisance error) caused by poor/weak plug connection at the Thermistor
Newest models have a Door Magnet at the 6 oclock location to allow keeping the washer door open---if desired. Useful for those consumers with the washer in a small/high traffic area laundry room
A large vent was added to the bottom/rear of the tub---which runs/routes up the right corner of the washer---for additional venting/airflow---when the washer is not in use (odor elimination when washer is used infrequently).
That's just a few of the updates/upgrades that I can think of
Bottom line---it's too new of a design to judge----using the 10 year benchmark.
To properly grade/critique the LG washers---we need to look at them as two versions...
Pre-2008 models and Post-2008 models
<<<If you overload the washer with a lot of cloths, will it damage the machine, or cause drop out with error msg. ?>>>
Overloading a front load LG washer will usually/simply result in---poor wash results.
If the washer cannot stabilized during the spin cycle (too heavy/overloaded)---a "UE" error will be displayed and the spin cycle will be aborted.
Infrequent overloading of the washer (we're talking excessively so) will *not*damage the washer.
