LG DLEX8377WM dryer Parts

To clear an LG DLEX8377WM dryer Flow Sense (airflow) warning, we reset the condition causing it: clean the lint filter and venting, then power-cycle the dryer. Flow Sense usually returns to normal after airflow is restored and the dryer is restarted.

Reset steps (in order)

• Turn the dryer off.
• Clean the lint filter completely (do this after every cycle as well).
• Check the exhaust path for restrictions: crushed flex duct, lint buildup, blocked exterior hood.
• Unplug the dryer for 5 minutes (or switch the breaker off for 5 minutes), then restore power.
• Run a timed dry cycle for 5 to 10 minutes and confirm strong airflow at the outside vent.

For model-specific operating and care guidance, use the DLEX8377WM owner's manual.

What to check if the warning comes back

Restricted airflow is the most common cause. These checks fix the majority of repeat Flow Sense alerts:

• Vent length is not excessive and has minimal elbows.
• Duct is rigid or semi-rigid metal (not kinked plastic or foil).
• Lint is not packed in the blower housing area.
• The lint screen cover area is sealing and not letting lint bypass.

If you find damage or poor sealing around the lint screen opening, replacing the dryer lint screen cover 3550EL1006B can help restore proper airflow through the lint filter path.

Quick symptom-to-cause guide

What you notice	Most likely cause	What we recommend
Clothes take too long to dry	Vent restriction	Clean/shorten venting, confirm outside flap opens
Dryer feels hot but airflow is weak	Blocked duct or hood	Clear lint, remove obstructions
Dryer shuts off or overheats	Airflow restriction causing high temps	Fix venting first, then retest
Warning appears soon after start	Severe blockage or crushed duct	Inspect behind dryer and at wall connection

Why it matters

Flow Sense is designed to protect drying performance and help prevent overheating. Restoring proper airflow lowers dry times, reduces heat stress on components like the heating element and thermostats, and helps your LG dryer run efficiently.

Yes for steam features; no for basic drying. On the LG DLEX8377WM, steam cycles and steam options require water in the steam system, but you can run normal timed or sensor dry cycles without using steam. Follow the fill and use directions in the DLEX8377WM owner's manual.

How water is used on this LG steam dryer

LG steam dryers use water to generate steam for cycles like Steam Fresh and for steam options that reduce wrinkles and static.

• Steam cycles require the steam system to have water available
• If you do not want steam, choose a non-steam cycle and do not select steam options
• If a steam cycle is started without water, the dryer can display an “ADD WATER” type message

What to do if you do not have a water hookup

You can still use the dryer for everyday loads; just avoid steam selections.

• Use regular cycles (Timed Dry, normal sensor cycles) without steam options
• If you accidentally select a steam cycle, stop the cycle and switch to a non-steam cycle
• Keep the steam feeder empty when moving the dryer

Steam feeder basics (what the manual calls out)

For steam cycles, the manual instructions focus on the steam feeder drawer.

Item	What to do	Why it matters
Steam feeder drawer	Pull out the drawer and fill to the MAX line	Steam generator needs the correct water level
Water type	Use water only (not detergents or additives)	Prevents sensor and steam system problems
Water temperature	Do not use hot water (over 86°F / 30°C)	Helps protect the steam system

Why it matters

If the steam system is not supplied with water, steam cycles cannot work as designed, and you can get poor wrinkle reduction or a water-level related message. Using non-steam cycles avoids those issues and still dries clothes normally.

The most common issue we see with LG dryers like model DLEX8377WM is poor drying performance caused by restricted airflow. A clogged lint filter or blocked venting makes cycles run long and can trigger overheating-related shutoffs; worn drum-drive parts can also cause noise or tumbling problems. See the DLEX8377WM owner's manual for care and troubleshooting steps.

Most common symptoms and what they usually mean

• Dryer takes too long to dry: lint filter or vent restriction, or weak airflow from the blower area
• Dryer shuts off mid-cycle: overheating from restricted airflow, or a temperature-sensing issue
• No heat or low heat: heating circuit problem (electric models), thermostat, or sensor issue
• Loud squealing, thumping, or grinding: belt, idler pulley, or drum support wear
• Clothes feel hotter than normal: airflow restriction or thermostat control problem

Quick checks we recommend first (fast, high-impact)

1. Clean the lint filter after every load (the manual notes the filter should be cleaned each cycle and the dryer should not run without it).
2. Inspect the vent path from the dryer to the outside hood for crushing, kinks, lint buildup, or a stuck damper.
3. Run a timed dry cycle and confirm strong airflow at the outside vent.
4. If the drum is not turning or you hear squealing, inspect the belt and idler system.

Common parts involved on DLEX8377WM

Symptom	Likely area	Example part on this model
Drum not turning, burning-rubber smell	Drum drive	Dryer drum belt 4400EL2001F
Squealing or chirping	Idler pulley	Dryer idler pulley 4560EL3001A
No heat or unstable temps	Heating and temperature sensing	Dryer heating element 5301EL1001J, dryer thermistor AGM30045804
Overheating symptoms	Safety temperature control	Dryer blower thermostat 6931EL3002M

Why it matters

Airflow problems do more than slow drying. They raise operating temperatures, which can cause repeated shutoffs, shorten the life of heating and thermostat components, and increase energy use.

Most LG dryers, including model DLEX8377WM, typically last 10 to 15 years with normal household use and basic upkeep. Consistent lint and vent cleaning, plus fixing wear items early (belt, rollers, thermostats), is what most often determines whether you land closer to 10 years or 15.

What affects dryer lifespan the most

• Airflow and venting: a restricted vent makes the dryer run hotter and longer.
• Lint control: cleaning the lint screen area reduces heat stress and drying time.
• Heat regulation parts: failed thermostats or a thermistor can cause overheating or poor drying.
• Drum drive wear: a worn belt, idler pulley, or rollers increases strain on the motor.
• Load habits: frequent overloading shortens the life of drum support parts.

Maintenance that adds years (simple routine)

• Clean the lint screen after every load.
• Check and clean the exhaust path regularly; keep the vent run as short and straight as possible.
• If drying times increase, address airflow first before replacing parts.
• Listen for squealing, thumping, or scraping; those are early signs of belt, idler, or roller wear.
• Follow the care and troubleshooting guidance in the DLEX8377WM owner's manual.

Common wear parts to watch on DLEX8377WM

If you notice symptoms, these are common repair areas for this model:

Symptom	Common cause	Example part on this model page
Drum not turning, burning rubber smell	Worn or broken belt	Dryer drum belt 4400EL2001F
Squealing or rattling while tumbling	Idler pulley wear	Dryer idler pulley 4560EL3001A
No heat or overheating	Heating or temperature control issue	Dryer heating element 5301EL1001J

Why it matters

A dryer that runs with poor airflow or failing drum support parts often overheats and overworks the motor and heater. Fixing the root cause early usually prevents bigger repairs and helps the dryer reach its full 10 to 15 year service life.
