On the covered LG washer platform, dHE means a temporary dry function error — LG's own wording. First, record the code and whether a dry cycle was running. dHE applies only to a washer-dryer with a drying function, so a stand-alone washer will not show it.

Before you touch a setting
Record this first — changing settings destroys the evidence
- That the display shows dHE
- Whether a dry cycle was running
- Whether the washer washes normally
- The model number

ReversibleRecord the code and whether a dry cycle was running.
Correct only the documented fault domain
ReversiblePower down and unplug the washer, let it rest for 10 seconds, restore power and restart the wash cycle.
Power down and unplug
ReversibleLG says a dHE error code is caused by a temporary dry function error. Power down and unplug the washer.
Rest for 10 seconds
ReversibleAllow the unit to rest for 10 seconds, restore power, and power the unit back on.
Restart the wash cycle
ReversibleRestart the cycle. If dHE persists, close the water tap and unplug the washer; LG says the unit will require a repair service.
Power down and unplug the washer
ReversibleLG's step for dHE is to switch the washer off and unplug it from the outlet, so that the control loses power completely.
Let it rest for 10 seconds
ReversibleWait for at least 10 seconds, as LG says, so that the control's memory clears and any temporary fault state is reset.
Restore power
ReversiblePlug the washer back in and switch it on, and check that the display returns to normal.
Restart the wash cycle
ReversibleLG says to restart the wash cycle, so choose a short wash first and see whether the washer runs without the code.
Run a dry cycle later
ReversibleOnce a wash has completed normally, try a short dry cycle to check that the dry function now works.
Contact LG if dHE returns
ReversibleIf the code comes back, contact LG support with the model number, since the dry heater or its sensor may need a technician.
Model-specific
What is true of this model and not of its siblings
- The code on this page
- dHE, a temporary dry function error.
- Parts involved
- The dry function and the control.
- LG's guidance
- Power down, unplug and rest the washer for 10 seconds.
- Washer-dryers are two machines in one
- A combination washer-dryer has a wash path and a dry path that share a drum but use different parts, such as a heater, a fan and a sensor for drying. A fault in the dry path can leave the wash path perfectly healthy, which is why the washer keeps washing when the dry function reports dHE.
- Help the dry cycle succeed
- Do not overload the drum for a dry cycle, since a drum that is too full cannot circulate air, and clean the lint filter and the condenser as the manual describes. A restricted air path can stop a dry function and trigger a fault.
Stop boundary
When this stops being a self-service repair
- !Unplug the washer and close the water tap if dHE persists, as LG says
- !Do not run repeated dry cycles on a unit that shows dHE
- !If dHE returns after the reset, book LG service
- !Unplug before any check
- !Use the wash function while the dry fault is open

Exact questions
Common questions
What does dHE mean on a LG washer?+
a temporary dry function error — LG's own wording.
How long should the washer rest?+
10 seconds.
Is dHE serious?+
Not usually, because LG describes it as temporary, and a restart often clears it.
How do I clear it?+
Power down and unplug the washer, wait 10 seconds, restore power and restart the wash cycle.
Can I still wash clothes?+
Yes, the wash function normally works, even if the dry function reported a fault.
When should I call LG?+
If dHE returns after the restart or the washer will not dry at all.
Does overloading cause dHE?+
It can, because a full drum cannot move air through the clothes, so dry smaller loads.
Should I clean the filter?+
Yes, a clean filter helps the dry function and avoids faults.
