Direct answer
On the covered LG dryer platform, Add, Add Water means a water supply error for the steam function — LG's own wording. LG states the steam feeder must be filled to the MAX indicator lines before a steam cycle. First, check the steam feeder is full of water and the drawer is completely closed.
Definition versus diagnosis
The display names a detected condition—not an automatically failed part.
What this covers
- LG dryer models covered by the cited manufacturer code family
- Displayed code or documented alias: Add, Add Water
- The operating stage and conditions described by the source
What it does not cover
- ×Another appliance type or original-manufacturer platform
- ×A code that merely resembles these characters
- ×Internal live electrical, gas, sealed-system or control-board repair
Verify the exact code and model
ReversiblePhotograph the complete display and model label. Code aliases in this record: Add, Add Water. LG vented, hybrid condensing and heat-pump dryers. Several codes apply only to one platform — LG states E13 appears on Hybrid Condensing Dryers, and E1/E4/Add/E05 only on models with the steam function.
Perform the first non-destructive check
ReversibleCheck the steam feeder is full of water and the drawer is completely closed. Do not clear the display before recording the operating stage and remaining water, heat or load state.
Correct only the documented fault domain
ReversibleIf the reading appears after a cycle has started, press PAUSE, fill the steam feeder with tap water to the MAX line, power the unit off and on, select the STEAM cycle and press START/PAUSE. Do not substitute a similar brand or product code table for the exact model manual.
Verify or escalate
ReversibleRun only a safe short test that reaches the original stage. If Add, Add Water returns, stop repeated resets and use model-specific manufacturer service.
