What E05 (Steam Water Supply) Means
E05 indicates a problem with the water supply used for the steam cycle, per LG's dryer Help Library article, distinct from the simple Add Water reminder - this is a genuine supply-fault code rather than a routine low-water notice.
Common Causes of E05 (Steam Water Supply)
- Water tap for the steam function closed, clogged, or frozen
- Inlet hose kinked, restricting water flow
- Inlet filter clogged with residue
- Water inlet valve fault (if the above checks don't resolve it)
🔧 One Safe Check You Can Try
Check that the water tap feeding the steam function isn't frozen or clogged and is fully open, check the inlet hose for kinks so water can flow normally, and clean the inlet filter to remove any residue.
⚠ Why You Shouldn't Go Further Than That
- If the tap, hose, and filter all check out but E05 persists after resetting the dryer, the water inlet valve itself needs a technician's inspection rather than repeated resets.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
