When strange noises start coming from your LG washing machine, it can be annoying. You wonder if something is wrong because your once-quiet and efficient machine now hums loudly during the wash cycle. You’re not the only one who encounters this problem and is unsure of how to resolve it.
A humming sound coming from a washing machine can indicate a number of issues, from minor adjustments to more significant issues. The first step in fixing any issue and getting your machine operating normally is identifying the cause, be it an imbalance in the load, a clogged drain pump, or something else entirely.
This post will examine the typical causes of your LG washing machine’s humming during the wash cycle and provide helpful fixes to help you resolve the problem. In this manner, you can maintain the efficiency of your laundry routine and prevent expensive repairs.
| Possible Cause | Explanation |
| Unbalanced Load | If the laundry is unevenly distributed, the drum might spin unevenly, causing the machine to hum. |
| Worn Bearings | Over time, the bearings in the drum can wear out, leading to a humming noise during operation. |
| Foreign Objects | Small items like coins or buttons stuck in the drum can create noise while washing. |
| Loose Parts | Loose screws or parts inside the machine can rattle and cause humming sounds. |
| Blocked Pump | If the drain pump is blocked or clogged, it can cause the washing machine to hum while trying to drain water. |
There are a number of common reasons why your LG washing machine may be humming during the wash cycle, including an uneven load, clogged filters, or a problem with the motor or pump. Early detection of the issue can stop additional damage and maintain the functionality of your computer.

Is the noise normal or abnormal?
You must first determine whether or not the LG washing machine’s audible hum exceeds the allowable standard. To accomplish this, locate the operating instructions for the machine and review the details regarding the highest noise level. This manufacturer’s models typically have direct drives, which reduces their noise output to between 50 and 60 dB.
Not quiet, but not loud either, is a noise level of 50–60 dB. But the only person who can tell by ear how loud the machine is humming is a qualified repairman. A noise meter is a specialized tool that is required for precise measurement by regular users. It won’t cost much if you locate a Chinese-made example, and it will make it evident whether you should be concerned about the outgoing noise or not.
An LG washing machine typically runs between 50 and 60 decibels loud.
If purchasing a noise meter is not necessary, you can compare the audible sound level to the noise "levels" that have already been measured. For instance, a functioning typewriter or a normal human conversation are said to be at 50 dB. The 70 dB threshold is appropriate for a busy street, 95 dB is audible in the subway, and a jackhammer operating generates 120 dB. It is simpler to monitor the hum’s normalcy using the provided examples; if you have any suspicions, initiate diagnostics.
Why the equipment washes too loudly?
A LG direct drive washing machine usually spins at 800-1200 rpm and produces very little noise while washing; at most, it makes some noise. However, there is a clear issue if the washing machine hums at startup and the drum essentially stops rotating. One of them is that the machine was installed incorrectly.
The unloosed transport bolts are typically the source of the problem when the washing machine hums during startup. These fasteners hold the tank firmly in place during transportation, preventing it from loosening and deforming, which makes them essential. However, they need to be taken out and the plugs put in before using the device. If not, the motor will attempt to spin the fixed drum upon starting, which could have catastrophic results. An unevenly standing case is another common installation error. Household appliances should ideally stand on a level surface; if this isn’t feasible, the feet need to be carefully adjusted.
Noise is another common result of internal machine malfunctions during rinsing. Among them are:
- Cracks in the tank. Replacement required.
- Loose bolts on the motor play. You need to tighten the screws tighter.
- Loose fasteners on the counterweights and upper springs. Remove the top cover and check if the bolts are loose. If the blocks themselves are damaged, then replace them.
- Worn bearings. A loud hum often occurs due to problems in the bearing unit. It is easy to confirm your guess: just spin the drum with the machine turned off and listen. If you hear a grinding or rumbling sound, then the culprit has been found, and you need to replace the parts. To make a replacement, you will have to disassemble the unit almost completely, right down to removing the tank. Next, we halve the container, knock out the worn-out ones bearings and install new ones. At the same time, we install new seals, which are responsible for sealing and protect the "rings". The machine is assembled in the reverse direction.
Another cause could be an unclean or poorly chosen hatch cuff. A hum is often caused by rubber crumbs that are left behind when the rubber rubs against the drum. Resolving the issue is simple: begin rinsing after taping fine sandpaper to the tank’s edge. In this manner, all of the debris is cleaned out of the friction area and removed with water.
A foreign object got into the tank
We’ll talk more about the possibility of a foreign object entering the tank. Practice demonstrates that this is what typically occurs and results in a loud hum. However, there are more severe repercussions, including a tank leak, in addition to auditory discomfort.
The truth is that a lot of metal items, like coins, bra bones, keys, and "tongues," get stuck between the plastic tank and the drum. In this instance, the machine keeps running while the stuck object scrapes against the surface, piercing both metal and plastic. Thus, there’s a hum, a knock, and a leak.
When the drum rotates throughout the cycle, you will hear a grinding, creaking, and humming sound, which makes it easy to identify that a foreign object is the source of the noise. It makes sense that eliminating the object is the only way to solve the issue. To accomplish this, you must take off the washing machine’s back panel, remove the heater by unscrewing the bolts holding it in place, and then shine a flashlight into the hole that has been created. As soon as the coin or keys are located, we reach inside and either create a metal wire hook or use pliers to hook our hand through.
There are a few common reasons why your LG washing machine might hum while it is washing. Noise can be produced by simple problems such as an uneven load, an object stuck in the drum, or an uneven surface for the machine. Taking care of these issues usually stops the humming.
If the noise continues, though, it may indicate a more serious problem, like a problem with the drum bearings or the motor. It’s a good idea to get professional advice in these situations to stop further damage to your machine.
Your washing machine can continue to operate smoothly and silently with routine maintenance and careful use. You can ensure that your appliance continues to operate efficiently and prolong its lifespan by taking immediate action in response to any unusual sounds.
