What E1, E4 means

E1 and E4 on an LG dryer point to an issue with the steam generator. They apply only to models that have the steam function. The dryer cannot make steam properly, so steam cycles stop and the code shows. A brief restart can clear a one-time glitch. The same characters on an LG Styler mean something different there, with E1 on the steam heater sensor and E4 on the steam heater, so keep the platforms apart. This page is for dryers.

Common causes of E1, E4

Steam generator
Sensor or heater that serves the steam system
Control output to the steam system

✓ One safe check you can try

1. Unplug the dryer. 2. Wait one minute. 3. Plug it back in and start the dryer. 4. Try a regular cycle first, then a steam cycle. 5. If E1 or E4 returns, call us. 6. Skip steam cycles until the dryer has been checked, and take wet clothes out of the drum.

! Why to stop there

If the code returns, we test whether the steam generator and its sensor work.
We keep the dryer separate from other LG platforms that use the same characters.
We run a steam cycle and confirm steam before we finish.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

E1, E4E1, E4 questions

Does E1 or E4 affect regular drying?

It may not. The code is about the steam function. Try a regular cycle after the restart. If drying works, you can use it without steam until the repair.

Is this the same as the Styler E1 and E4?

No. The characters match, but the Styler has a different steam system. This guidance is for dryers only. This guidance is for dryers only, so please do not use steps meant for a Styler on your dryer.

Do all LG dryers have this code?

No. It applies only to models with steam. If your dryer has no steam, tell us the exact model so we can check the code.
