Technical manual summary
This 50-page LG manual covers the WT7100CW top-load washer. It separates installation and owner-care information from technician disassembly, wiring, error-code diagnosis and component testing. The contents provide a practical route to the section relevant to the reported problem.
The drainage section treats OE as a starting point for diagnosis and includes the drain path, pump, connectors and control checks. Other sections address motor, balance, overflow and pressure-sensing faults. An error message alone is not enough to select a replacement part.
The final portion includes component-specific diagrams, exploded views and wiring information. The source’s electrical, mechanical and ESD precautions apply to technician work. For routine use and care, the current LG owner-support page is a separate reference.
WT7100CW is printed on the cover. A base-model match does not establish every regional suffix or later component revision. Use the exact product label and applicable service literature before electrical tests or ordering parts.
Document references
LG provides current owner-document downloads for WT7100CW.ABWETUS. That support listing is a reference for the named suffix, not proof that this saved service PDF covers all suffixes.
