Why does my dryer take so long to dry clothes?
Poor airflow can increase drying time. A lint filter that is full of lint or clogged with fabric softener sheet residue can reduce airflow and make drying take much longer. The manual also refers you to the troubleshooting charts for more tips.

Why does my washer make loud banging noises while it is filling with water?
It is usually caused by plumbing in your home, not by a washer defect. When the water valve shuts off, your pipes can move and make a banging noise called water hammer. A water hammer arrestor can reduce it.
- LG · Laundry · WM4000HBA · reviewed answer
Why does my washer thump during a cycle?
Heavy wash loads can produce a thumping sound, and an out-of-balance load can also cause it. If the sound continues, stop the washer and redistribute the load; you can pause the cycle and do this after the door unlocks.

Why does the dryer run but not heat?
Possible causes listed are a blown house fuse, a tripped circuit breaker, a power outage, the gas supply or dryer shutoff valves being off, or the Energy Saver option being selected. Make sure the gas shutoffs are fully open, and if using the Normal cycle, deselect Energy Saver.

Why does the estimated time sometimes change after I start a cycle?
After you press Start/Pause, the washer measures the load size, so the estimated time may change once load sensing is complete.
- LG · Laundry · WM4000HBA · reviewed answer
Why does the washer make a banging noise when filling with water?
This is described as water hammer. It is caused by household plumbing moving or flexing when the washer valves shut off, and it is not a washer defect. The manual suggests water hammer arrestors, or lowering very high household water pressure.

Why don’t I see steam at the beginning of the cycle?
That is normal. Steam is released at different stages of the cycle depending on the option selected.

Why is detergent not dispensing completely?
Common causes are putting detergent in the wrong compartment, not closing the dispenser drawer fully, using too much detergent, low water supply, or normal residue buildup in the dispenser.
- LG · Laundry · WM4000HBA · reviewed answer
Why is there so little water in my washer? How can it clean the clothes?
That is normal for an HE (High-Efficiency) washer. It uses a minimum amount of water and energy, and the low water level makes the detergent more concentrated for effective cleaning.
- LG · Laundry · DLEX4000B · reviewed answer
Why should I clean the lint filter before every load?
A clogged lint filter increases drying time. The filter should be cleaned and reinstalled firmly before starting the dryer.
- LG · Laundry · WM4000HBA · reviewed answer
Why should I flush the water hoses before using the washer?
Flushing removes foreign substances like dirt, sand, or sawdust. The manual says these can damage the washer inlets and cause leakage.
- LG · Laundry · DLEX4000B · reviewed answer
Why won’t the dryer turn on?
The manual lists a blown house fuse, a tripped circuit breaker, or a power outage as possible causes. Reset the breaker or replace the fuse. Do not increase fuse capacity. If the problem is a circuit overload, have it corrected by a qualified electrician.
- LG · Laundry · WM4000HBA · reviewed answer
Why won’t the washer let me choose a temperature, spin speed, or option I want?
Not every temperature, spin speed, soil level, or option is available on every cycle. If the setting is not allowed, the washer sounds twice and the LED does not light.

Will LG provide in-home repairs for an in-warranty product?
Yes, but only if the product is within a 150 km radius of the nearest authorized service center, as determined by LG Canada.
