MODEL OVERVIEW
About this model: LG DLHC8402W
LG DLHC8402W ventless heat-pump dryer displays distinct sensor, motor, pump, cover and drainage codes.
Identify the Alpine White rear-control heat-pump dryer
DLHC8402W is the Alpine White member of LG's 7.3-cubic-foot DLHC8402 heat-pump dryer family. The exact product variant links a two-page specification with this white SKU, and its own support page links an English owner manual whose cover says DLHC8402*. That source chain matters because the photographed rear-control panel, its LED status window and its error table can be connected to this machine rather than borrowed from a similar LG dryer. Its ventless heat-pump design also changes the questions an owner should ask: a drainage or condenser-cover message is relevant, while advice written for a conventional exhaust duct is a poor starting point.
The specification calls this a rear-control electric dryer with eight programs, fifteen selectable options, AI Sensor Dry, a variable compressor and 6 Motion drying. The EasyLoad door, Wi-Fi, Smart Diagnosis and automatic condenser cleaning help identify its feature set; steam is explicitly absent. The panel page shows a cycle-selector knob, Start/Pause and a display for status messages. Record the exact letters shown before trying a remedy. A chosen drying level, cycle stage or estimated finishing time describes operation, whereas the separate error-message table names conditions the controller has detected.
Separate routine reminders from fault messages
The control guide says Clean Filter lights at the beginning of a cycle and turns off when Start/Pause is pressed. That is a prompt to inspect the lint filter, not the same thing as code IF. The Condenser Clean icon appears when water is being sprayed on the condenser; its presence alone reports an automatic cleaning stage. Dry and Cool lamps likewise describe the phase of the cycle. The remaining-time figure may change while Sensor Dry recalculates progress, so a shifting estimate is not evidence of a broken sensor.
If a fault appears, pause and transcribe its characters instead of treating every light as an error. On this model IF says the lint filter is missing from the appliance; reinstalling the filter addresses the condition described in the table. CC says the dryer is operating without the condenser cover, so the access panel and cover should be assembled as the manual directs. These are physical-presence messages and differ from the routine filter reminder and condenser-cleaning status. The distinction is useful because repeatedly restarting a cycle cannot replace a missing filter or cover.
Interpret temperature and drive codes precisely
The p46 table groups tE1, tE2, tE4, tE5 and tE6 under a temperature-sensor malfunction. It separately labels F1 as a sudden rise in drum temperature. For these sensor and temperature conditions LG tells the owner to unplug and call for service. The letters are not drying-temperature choices. A reader should avoid treating the number after tE as a suggested temperature setting or silently assuming that one tE code covers every heat-pump problem.
LE1 is the drum motor stopping suddenly; the table first asks whether the load exceeds maximum capacity and then directs disconnection and service. LE2 and AE refer to a compressor that has stopped. LE3 is printed twice, once for a fan motor stopping and once for an internal fan malfunction, so the code alone does not identify which fan needs work. These are different from a delayed sensor-dry estimate. Note the exact displayed code, the load and the stage at which operation stopped, then follow the manual's service instruction rather than attempting internal electrical repair.
Trace pump, water and drainage messages
OE identifies a drain-pump motor malfunction. The same OE row also discusses an installation location below freezing and gives a 41–95 °F recommended surrounding temperature. These details help avoid reducing OE to a generic “wet clothes” complaint. IE describes the water inlet path: a closed valve, interrupted supply, frozen or clogged hose, or a hose connection that needs correction. The table directs checks at the valve, faucet and strainer. These water-supply explanations are different from the heat pump's lack of an exhaust vent.
The next page lists drN for no drainage, with a drain hose that is unconnected, kinked, blocked or trapped behind the dryer. Start with the hose route the manual actually names; do not confuse drN with OE's pump-motor row. A water leak appears later under general operation symptoms, where hose connections are discussed without claiming that a separate leak code was displayed. The distinction keeps the article useful when the dryer shows letters, and avoids assigning a made-up code to a puddle or a cycle that finishes early.
Check installation messages and know when to stop
PS is the low-voltage entry in the error table and says the power cord is connected incorrectly; the manual directs checking its terminal-block connection. Because that involves electrical supply, the table is a reason to stop use and obtain a competent installation or service check, not an invitation to work on a live connection. The exact specification calls for a 240 V or 208 V electric supply and does not describe a gas burner. Keep the machine identity and the displayed letters together when contacting service, especially if a temperature, compressor, motor or pump fault has appeared.
The DLHC8402W's combination of ventless heat pump, auto-cleaning condenser, rear LED panel and physical filter/cover checks gives a practical order for triage. First distinguish normal Clean Filter, Condenser Clean and Dry/Cool status from codes. Then make only the external checks named for IF, CC, IE or drN. A tE, F1, LE, AE, OE or persistent PS entry warrants the stronger service path stated in the owner manual. Retain the exact code and page reference when describing the fault; the official table, rather than a generic heat-pump checklist, is the anchor for this white model.
