<<< 005KWTA00401 >>>
Built May 2010
<<< We'll start it on a regular 2-hour wash cycle, and it does okay for a lot of it. But then in the middle to later part of the two hours, it stops and displays the LE error code. At this point it's full of water, and the soap dispenser is open and empty, so it's operated okay for quite a while. What I've done is turn it off and back on, then I set it on a rinse-only cycle. It seems to do this fine without any problems. >>>
<<< the problem is intermittent. >>>
Most likely causes---in the following order...
Failing Wash Motor ( http://www.appliancepartspros.com/lg-motor-assembly-wm-4681ed1004b-ap5325099.html
Debris in Wash Impeller Housing---requires removing filter cover inside DW (causes noise complaints and/or "LE" error)
Nearly severed/broken wire at the bottom of the door (must remove front panel to inspect)
This dishwasher DOES NOT have the older tar-like insulation and therefore wiring within the door---is NOT a known issue for problems.
Wire(s) can still be an issue at the very bottom of the door (from opening & closing the door---pulled apart)
Other known issues with this dishwasher model (and build date)
If the Serial Number is within the range of 501KWxxx through 011KWxxx---the Guide Assy has been re-designed to prevent *very random* water leaks at the lower corners of the door.
The part number (4975ED1005B) has *not* been changed.
Replacement Guide Assy must have a build date (ink on part) of November 2010 or newer
The Chopper/Mascerator Blade within the Sump Assy (located at the center of the tub inside the DW) has been changed from part number (5832DD4001A
) to (5832DD4001B
)---to eliminate grinding/whirring noise that occurs during the *wash cycle*.
The Filter Assy (ADQ32598202
) has been re-designed (smaller holes) to prevent hard debris from entering the lower portion of the Sump Assy---which can at a minimum cause noisy Wash Motor or Drain Motor operation.
Debris in the Wash Motor/Impeller housing *could* cause potential "LE" errors (again this would be in addition to noisy wash cycle operation).
Debris which enters the Drain Motor housing *could* cause a potential "OE" error (no drain) or noise during the drain cycle
The part number for the re-designed Filter Assy has NOT been changed.
Replacement Filter Assy must have a build date after Oct 22 2012
