LG Washer dHE Error — Temporary Dry Function Error Fix

What it means

LG washer dHE error appears on LG WashTowers and LG combined washer-dryers — LG's 'Temporary dry function error' code.
The dry function isn't reaching target temperature or the dryer condenser/sensor has a fault.
The wash side of the unit usually still works — only the dry side is affected.

Affected Models

LG Front Load Washer
LG Top Load Washer
LG WashTower (combined washer + dryer)
LG TurboWash Washer
LG TwinWash Washer

Common Causes

Lint filter blocked or full
Condenser unit blocked with lint (LG WashTower)
Dryer thermistor reporting out-of-range temperature
Heating element in the dryer failed
Vent or ducting blocked (vented dryer models)

How to Fix It

Clean the lint filter thoroughly.

Pull out the lint filter (usually inside the door area on LG WashTowers).
Brush off all visible lint.
For deeper cleaning, soak the filter in warm soapy water, scrub gently with a soft brush, rinse, and dry completely before refitting.
Clean the condenser (WashTower).

On LG WashTowers, the condenser is accessible behind a panel at the bottom of the dryer.
Pull it out, vacuum loose lint, and rinse if it's heavily clogged.
A choked condenser is the single most common dHE cause.
Run a normal dry cycle to test.

After cleaning, start a short dry cycle.
If dHE doesn't return, the cleaning fixed it.
If dHE comes back, the thermistor or heater needs investigation.
Check the vent hose (vented models).

If your unit is a vented dryer (not condenser), check the vent hose for kinks and lint build-up along its length.
Outside the house, check the vent flap for obstruction (bird nests, leaves).

When to Call a Professional

dHE often clears with a thorough lint and condenser clean.
If cleaning doesn't fix it, the dryer thermistor or heating element needs technician replacement — both inexpensive but require accessing the dryer's back panel.

Frequently Asked Questions

Why does dHE only appear on long dry cycles, not short ones?

Because the heater runs for longer on long cycles, giving more chance for the temperature to climb out of range or for the thermistor to detect drift.
Short cycles end before the issue becomes critical.
If dHE only appears on long cycles, the lint filter and condenser are the prime suspects — partly-blocked airflow heats the dryer faster than designed, and the thermistor trips dHE to protect the unit.
