LG Dishwasher Repair in Toronto — Error code flashing

• The first thing we settle on any LG error-code call is which family the code is in, because LG's own Error Code List splits them into a fault that needs a part and a non-fault that just needs clearing. CL is the big one: LG's support defines CL as the control-lock (child-lock) feature, NOT an error — the panel locks every button except Power and ignores Start. We clear it by holding the model's control-lock combo (commonly Rinse + Spray, or Half-Load + Energy-Saver) about 3 seconds, then breaker-cycle 60 seconds if it won't drop. Reading CL as a board fault and quoting EBR86473413 is the classic mis-diagnosis we rule out before anything else.
• OE is LG's most common hard code and where most error-code dispatches land. LG's OE flow has us clear the dual sump strainer first (coarse filter over a fine mesh cup at the tub floor) — trapped food, labels or seeds re-throw OE before any part is suspect. When the sump is clean and a forced drain still posts OE, the drain pump ABQ73503004 (AP5973786 / PS11706890, supersedes ABQ73503002) is condemned: a glass chip or fruit pit past the strainer jams the impeller so the coil reads fine but the rotor is locked. We bench-spin the impeller and meter the coil before swapping. OE is a separate pump from the wash motor, so an OE code never justifies the ABT72989206 circulation motor.
• AE (older panels read E1) is LG's leak code and the one that masquerades as other faults on the code reader. LG's AE & E1 page defines it as base-pan water tripping the float switch, at which point the control commands a continuous protective drain — so the pump runs non-stop and the cycle never advances, which owners read as 'won't run / won't drain.' We dry the pan so the float drops, trace the real seep path (door-gasket corner, sump O-ring, inlet drip), and only condemn the float/leak switch 6601ER2001C (RepairClinic 4985714) when the pan is bone-dry and AE still latches with a stuck-tripped signal. Over-sudsing from non-HE detergent also posts AE — we run a no-detergent cycle to clear a foam trip before selling a seal.
• LE and CE are LG's motor/communication codes and have to be split apart on the reader. LG groups LE as a circulation-motor (inverter direct-drive) fault — a seized or debris-jammed wash rotor, or a winding that won't read continuity — fixed with the wash pump+motor assembly ABT72989206 (AP6334593, supersedes ABT72989202; this casing also carries the integrated heater on QuadWash LDF/LDT/LDP tubs). CE is the main-PCB-to-sub-board communication fault: LG and distributor literature peg it to the harness between the boards or a board itself, and LG's first step is a breaker-cycle (off 10 seconds, back on, restart). We breaker-reset CE first, then inspect the inter-board harness before condemning EBR86473413 — a one-off CE often clears on reset.
• nE is a real LG code that gets mistaken for a wash-pump fault but is actually the vario/diverter motor — the small geared motor that switches water between the lower, middle and upper spray arms has stopped reporting that it's turning. LG throws nE on failed diverter windings (spec ~2.7–4.0 kOhm), a dead or misaligned position microswitch, bad wiring, or debris fouling the diverter valve. We meter the diverter coil and test the position-switch plunger; the fix is the inexpensive vario/diverter motor 4681ED3001D (AP5243567 / PS3579323, replaces 2020847 / 4681ED3001B), NOT the ABT72989206 circulation motor. Throwing a wash pump at an nE code is money wasted.
• HE and tE are LG's two heat codes and we keep them straight on the reader. HE is the heater circuit fault — LG posts it when the unit can't heat or sees overheat past ~149°F — and we ohm the element (LG units meter roughly 12 ohms) before condemning anything. tE is the thermal/thermistor error: LG throws it when water reads over ~194°F or the temperature sensor is bad, and LG's own spec puts the thermistor near the sump at about 11.8 kΩ at room temperature (~77°F); a reading far under ~1 kΩ or over ~20 kΩ condemns it. On older LDS/LDF/D-series tubs the heater is a discrete element 5301DD1001G (cross-ref AP5272210); on newer QuadWash LDF/LDT/LDP tubs the heater is integrated into the ABT72989206 pump/sump casing and not sold separately, so an HE that traces to the element on those models means the bigger assembly.
• IE and FE are LG's two water-level codes and they fail in opposite directions, which the code tells us instantly. IE means the level was too low after the fill window — usually the inlet valve 5221DD1001F (AP5810251 / PS9495756, supersedes 5221DD1001A) or its scaled inlet mesh screen, low supply pressure under ~20 psi, or a flood-safe AquaStop hose choking the fill. FE is the overfill twin: LG detects too much water and auto-runs the drain pump, driven by a stuck inlet valve that keeps passing water, a float/level sensor with a pin-hole that fills and reads false, or suds. We crack the door mid-fill (flow should stop instantly) to catch a valve passing by, and clear/replace the 6601ER2001C float on a confirmed false reading rather than chasing the wash motor.

LG error code flashing in Toronto — the local specifics

• The recurring LG-in-Toronto pattern on error-code calls is that the code is a starting point, not a verdict: OE that's really a clogged dual sump strainer, IE that's really a scaled inlet screen on the city's hard water, AE that's really a base-pan suds trip or a weeping door-gasket corner rather than a dead float, and CE that clears on a single breaker-cycle. We routinely arrive on a 'board error' that turns out to be CL control-lock the owner triggered by accident. The genuine hard-part codes we see most are OE (drain pump ABQ73503004) and IE/FE (inlet valve 5221DD1001F), with LE/nE motor codes the occasional bigger job.
• We bring the fast-failing code parts to LG dishwasher calls: the ABQ73503004 drain pump for OE, the 5221DD1001F inlet valve for IE/FE, the 6601ER2001C float/leak switch for AE/FE, and the 4681ED3001D vario/diverter motor for nE — plus a meter for the thermistor (tE, ~11.8 kΩ at room temp) and heater element (HE) so we confirm before ordering the model-specific ABT72989206 pump+heater casing or EBR86473413 board.
