Where does this unpleasant sound come from?
The automated machine may operate excessively loudly for a number of reasons. The majority of them show up right during the primary wash. What could be the reason behind the washing machine’s loud humming right after the used liquid is drained? The drain pump should be looked at as the primary source of noise because it starts up before the water starts to exit the tank. One of the following causes the pump to roar when draining:
- if it is clogged;
- if the pump is damaged;
- when the drain hose or pipes are clogged;
- when debris accumulates in the drain filter.
The "growling" sound usually happens just before spinning, but after the rinse. But, once the cycle is over and the water is almost completely drained, the washing machine might begin to hum. We will explain what to do later on when stating problems.
How to troubleshoot?
Finding and removing the source of the washing machine’s loud noise is not difficult. The forthcoming work front is manageable even for a non-professional. Where should the repair begin? using the sections that are simplest to inspect. Examining the trash filter should be done first in this situation.
LG washing machines have the drain filter behind a small panel at the bottom, in the right corner. The door can be easily opened by using a slotted screwdriver. Simply place the tool’s tip inside the crack and pry the door open. After that, you must take these actions:
- take a piece of cloth and put it under the machine, the rag will absorb the water flowing out of the filter hole;
- unscrew the cover from right to left;
- remove the filter element from the housing and wash it, preferably with detergent;
- inspect the hole that appears after pulling out the drain filter. Take accumulated garbage from the cavity, wipe the walls from dirt;
- install the waste filter in its original place, carefully, so as not to strip the threads, tighten the cover;
- run the machine cycle in test mode, check if you managed to cope with the noise.
This method might not work to unscrew the drain filter if it is very clogged; in that case, you will need to remove the element and pump from inside the case.
The drain hose and the pump need to be inspected in addition to the waste filter when the check indicates that it is not clogged. The hose is visible on the back of the case, but you must first access the pump in order to disconnect it for inspection.
The majority of LG washing machine models have the drain pump at the bottom of the machine. Simply turn off the machine, unplug it from the communications network, and turn it upside down to remove it. Following that, you must take the pump apart, check the chamber for debris, and give the pump impeller a thorough cleaning. You can ask a specialist to perform this procedure if you are too scared to do it yourself.
Examine the hose and pipes thoroughly after cleaning the drain pump. Therefore, disconnect the drain hose that is fastened to the pump using a specialized clamp first. The sewer pipe connector on the other end of the tube has already been disconnected. You will be holding the hose the entire time. You must rinse the element well and clear any existing blockages.
Using a unique rod with a brush at the end, the drain hose can be cleaned. The cable’s diameter shouldn’t be larger than one centimeter. The following will be the sequence of events:
- insert the rod into the drain hose;
- move the cable back and forth inside the tube;
- wash the cavity under the tap with running water;
- install the drain hose in its original place;
- assemble the washing machine and connect it to the network.
Once a minor repair is finished, you ought to put the device into test mode. At this point, adding a specialized tool to clean the "insides" of the machine is advised. It makes sense to swap out the damaged element for a functional one if damage to the drain hose or pump is found.

| Blocked Drain Pump | Check and clean the drain pump filter to remove any debris. |
| Clogged Drain Hose | Inspect the drain hose for any blockages and clear them if needed. |
| Faulty Pump Motor | If the noise persists, the pump motor may need replacement. |
| Loose Parts | Tighten any loose parts in the washing machine that could be causing the noise. |
It’s crucial to take action if your LG washing machine hums while emptying the water. This noise might indicate a blockage, a broken drain pump, or even something as straightforward as a foreign object lodged in the drain filter.
To begin resolving the issue, make sure there are no obstructions in the drain hose or filter. A closer inspection of the drain pump may be necessary if the noise continues. In most cases, the repair is simple, but if you’re not sure, it’s best to call a professional to avoid more damage and save time.
