LG Washing Machine Repair in Toronto — Not agitating (top-load)

• On LG direct-drive front-loads the drum tumble IS the agitation, so a washer that fills and drains but never turns the drum is the signature LE complaint — LG defines LE as a Locked Motor Error (a locked-rotor fault); the control cannot confirm the rotor is turning so it aborts before tumbling. The first real part, after a power reset and a hand-spin of the drum to rule out a jam, is the rotor-position (hall) sensor 6501KW2002A / 6501KW2002B (AP7015078, cross-refs PS3529186 / AP4440680) already on our sheet for the won't-spin path: LG has revised this RPS over the years and distributors list the two revisions as interchangeable, so we fit whichever the channel ships. When it stops reporting rotor position the drum won't spin OR agitate at all, which is exactly the no-tumble presentation. We confirm with SmartDiagnosis and a tumble/wash-only test before condemning it.
• A no-tumble LE where the hall sensor itself tests good is very often the motor wire harness 6877ER1016F (genuine LG, AP4442257, supersedes 6877ER1016B / 1364148; cross-refs AH3530237 / EA3530237 / PS3530237) — the multi-wire harness carrying power and the position signal between the drive motor and the main control. A loose, chafed or broken conductor in this plug breaks the rotor-feedback loop and the control reads a locked rotor, so the drum sits dead even though the motor and sensor are fine. The field test is continuity across the harness wires at the connector; an open conductor confirms it. LG and the aftermarket sell this as a 6877ER1016F harness (some channels bundle it with the 6501KW2002 hall sensor as an LE repair kit), and reseating or repairing the plug is a free-to-cheap fix we rule in before quoting the stator or board.
• When the rotor won't develop torque to tumble, the fault can be the stator assembly itself — LG sells it as 4417EA1002K (and the 4417EA1002Y variant that ships with the hall sensor already mounted). The stator generates the electromagnetic field that drives BOTH agitation and spin on these belt-less direct-drive machines, so a shorted or open winding leaves the drum unable to turn under load and throws LE. Because the hall sensor clips to the stator, we inspect both together once the rotor is off, and on a confirmed winding fault the stator is replaced as the assembly — it is not a wound-on-site part.
• A no-agitate LE that is mechanical, not electrical, on the direct-drive rotor: the central rotor bolt backs off so the rotor no longer locks to the shaft (we re-torque it and lock it with blue threadlocker), or a rotor magnet on the AHL72914402 rotor assembly cracks or loosens so the motor can't grab the field to turn the drum. Broken or loose magnets read as the same locked-rotor LE as a dead sensor. We pull the rear panel, inspect the rotor face for chipped magnets and a slipping hub, and re-seat the bolt with threadlocker before quoting any sensor, harness or stator — a swap on a stripped rotor bolt buys nothing.
• On LG TOP-LOAD WT machines (not the front-loads) the classic not-agitating presentation is a washer that fills, spins and drains but the wash plate never moves — that splits the drive: the shift-actuator coupling 4323EA2001C (ACP72929002 / AP5674447 / PS3522903; the drive-shaft-and-shifter form is AEN73131402 / AEN73131406) transfers motor power and shifts the drive between agitate and spin, and when it wears the machine can spin but loses agitation. We watch a wash-only cycle to confirm the plate is dead while spin still works, which points at the coupling/shifter rather than the motor or board.
• The other top-load WT no-agitate is purely mechanical at the top of the shaft: the wash plate / pulsator AGZ72909702 rides on the splines of the drive shaft, and when those splines strip the motor and coupling turn but the plate just sits there or rocks loosely. The tell is a wash plate you can wiggle by hand — stripped splines on the plate, or on the shaft below it, kill agitation while spin (which is basket-driven) can look fine. Per RepairClinic this is the most common reason an LG top-load wash plate gets replaced; a worn clutch is often what stripped the splines in the first place, so we check the shaft splines before reusing any plate.
• Chronic overloading — the king-duvet wash we hear about weekly — is the upstream cause behind a real share of LG no-tumble LE faults: the rotor is forced to start against a load it cannot move, which over time stresses the hall sensor (6501KW2002A / 6501KW2002B), works the rotor bolt loose and fatigues the motor harness 6877ER1016F. Honest LE diagnosis separates a genuinely failed part from a usage pattern, because a sensor or harness swap on an owner who keeps overloading just buys time before the next locked-rotor abort.

LG not agitating (top-load) in Toronto — the local specifics

• The recurring Toronto pattern on LG not-agitating calls is the LE locked-rotor abort on front-load WM machines that follows chronic overloading — the oversized duvet or comforter wash that an LG direct-drive drum can't start against — and it shows up disproportionately in shared-laundry buildings where one machine does heavy household loads. We also see the top-load WT 'spins but won't agitate' variant land as a separate, mechanical call (a stripped wash plate or worn shift coupling), distinct from the front-load electrical LE faults.
• We carry the LG LE essentials to these calls: the 6501KW2002A/B rotor-position (hall) sensor and the 6877ER1016F motor wire harness (often as the combined LE repair kit), plus blue threadlocker for a backed-off rotor bolt. The stator (4417EA1002K), rotor (AHL72914402), and top-load coupling/wash-plate parts (4323EA2001C / AGZ72909702) are confirmed by model/serial and brought next-day when the on-van sensor-and-harness check rules them in.
