LG Dryer Error Code E5 — Steam Water Supply Problem
What this means
The E5 error code on LG dryers with a steam feature indicates a problem with the water supply used for the steam cycle. The dryer cannot draw water to generate steam, which may be caused by a closed water tap, a frozen or clogged inlet hose, a blocked inlet filter, or low water pressure. This error only appears on LG dryer models equipped with the TrueSteam or steam refresh feature.
Step-by-step fix
3 stepsCheck the water supply tap
Verify that the water tap connected to the dryer's steam supply hose is fully open. Turn the valve counterclockwise to ensure maximum flow.
Some installations share a cold water line with the washer — make sure the splitter valve is also open for the dryer.
Inspect the water inlet hose
Disconnect the water supply hose from the back of the dryer. Check for kinks, damage, or ice blockage (in winter). Run water through the hose to confirm it flows freely.
In freezing temperatures, a frozen inlet hose is a common cause. Thaw it with warm towels before reconnecting.
Clean the inlet filter screen
At the dryer's water inlet connection point, locate the small mesh filter screen. Remove it carefully with pliers and rinse it under running water. Use a small brush to remove mineral deposits or sediment buildup.
If you have hard water, clean the filter every 3 months to prevent E5 errors from recurring.
When to call a professional
If the water supply, hose, and filter are all clear but the E5 error persists, the water inlet valve inside the dryer may be defective and requires professional replacement.
