Any washing machine, regardless of its age and condition, necessarily makes various sounds during operation. It is worth noting that even properly installed washing equipment cannot operate absolutely silently. If the washing machine hums when draining water, and the nature of the noise differs significantly from the standard one, you need to start looking for various faults in the equipment components. We will describe in detail each breakdown of the washing machine units, which provokes the appearance of third-party sounds during drainage of water.
The reason for the hum of washing equipment
One of the most common causes of extraneous noise when draining water from washing equipment is the presence of small objects or small pieces of clothing in the drum. For example, small coins, buttons, various metal fittings, a sock, etc., which fall into the space between the tank and the drum and, when the latter rotates, produce various sounds.
All these items must be removed without fail, as they can cause more serious problems and malfunctions in the washing machines.To do this, the machine must be partially disassembled. More detailed instructions can be found on the Internet. But we strongly recommend that you do not carry out any serious repair operations yourself, but rather contact highly qualified craftsmen from a specialized service center.
You should also pay attention to the fact that the user of the equipment may be to blame for the occurrence of third-party noise when draining water from the washing machine. For example, in case of incorrect installation and connection of the washing machine, or its drum is overloaded.
Let us consider in detail the main malfunctions that cause extraneous sound when draining water after the washing process is completed.
The washing machine is not installed correctly
A significant level of noise when draining the washing machine may be a consequence of improper installation of the equipment. In this case, we recommend contacting a qualified technician who will quickly eliminate all existing shortcomings.
Only if installed correctly will the washing machine function correctly and its service life will be as long as possible. If the washing machine was initially installed and connected incorrectly, various malfunctions may occur in the future due to a violation of its position.
Forgot to remove the shipping bolts
Any new washing machine has special shipping bolts, the purpose of which is to prevent damage to its individual elements during unloading and transportation. Before installing the equipment, they must be removed in order to completely prevent incorrect operation in the future. The manufacturer must indicate this point in the technical documentation for the product.
It is worth noting that unremoved transport bolts can cause serious damage to the washing machine after it is turned on. After purchasing a new washing machine, be sure to pay attention to this feature. We recommend that you keep the protective bolts, as they may come in handy if you need to transport the washing machine again.
Clogged drain hose or pump 
If you can clearly hear an extraneous sound while draining water, it is quite possible that the cause of its occurrence was a clogged pump or hose. Small items of clothing (socks, swimming trunks, etc.) and various accessories from clothing can get into these elements, disrupting the normal flow of the line.
To eliminate the cause of extraneous noise when draining water from the washing machine, you should clean the drain hose or pump. To do this, you need to find a special hatch on the front lower part of the washing machine that covers the filter. You need to clean the filter element as much as possible and remove all small debris that can get under the impeller of the pump and serve as a source of noise. The drain pump has failed
The water drain pump can fail on any washing machine, regardless of its build quality and service life. Its malfunction is always characterized by the presence of a hum during water drainage when the washing machine is operating. Only a highly qualified specialist can fully restore the unit's functionality. It is worth noting that in some cases, this element needs to be replaced, which should also only be entrusted to service center technicians.It is worth noting that transportation bolts that have not been removed can cause serious damage to the washing machine after it is put into operation. After purchasing a new washing machine, you must pay attention to this feature. We recommend that you keep the security bolts as they may be useful if you transport the washing machine again.
The drain hose or pump is clogged
If you hear a distinct sound when draining water, it is quite possible that the cause is a clogged pump or hose. Both small parts of clothing (socks, swimming trunks, etc.) and various accessories from clothing can get into these elements, disrupting the normal flow of the highway.
To eliminate the cause of extraneous sound when the washing machine drains water, you should clean the drain hose or pump. To do this, you need to find a special hatch on the front bottom of the washing equipment that closes the filter. It is necessary to clean the filter element as much as possible and remove all small debris that can get under the pump impeller and serve as a source of noise.
The drain pump has failed
The water drain pump can fail on any washing machine, regardless of its build quality and service life. Its malfunction is always characterized by the presence of a hum when water is drained when the washing equipment is operating. Only a highly qualified specialist can fully restore the unit’s functionality. It is worth noting that in some cases, replacement of this element is required, which also must be entrusted only to service center technicians.
In the case of self-restoration or replacement of the drain pump, it is necessary to correctly select the appropriate part. For example, a pump for an LG washing machine will not fit on a Samsung, and vice versa.
We definitely recommend contacting a specialized service center, since only in this case will a guarantee of the continued correct functioning of the washing equipment be provided. We emphasize that any user intervention voids the product’s manufacturer’s warranty (if it is still valid).
- Bearing wear
- Natural wear of bearings often provokes the appearance of third-party sounds during operation of an automatic washing machine. At the same time, the noise always increases at maximum drum speeds (during the operation of the equipment in the spin and drain mode). As a rule, bearings wear out after prolonged use of the washing machine (more than 5-10 years).
- Also, the cause of damage and wear is metal corrosion, which severely destroys the bearings. If the sealing seals fail, moisture constantly enters the bearings, as a result of which they quickly rust and fail, causing extraneous noise and incorrect operation of the washing machine.
- The main signs indicating the need to replace the bearings of a washing machine:
- the presence of traces of rust on the surface of the drum;
- a hum occurs when the drum rotates at maximum speed in spin mode;
- the occurrence of vibrations;
difficulty rotating the drum;
presence of liquid on the floor where the washing machine is installed;
poor quality laundry;
centrifuge jamming due to imbalance of the drum due to bearing wear.
The solution to the problem is to completely replace the worn oil seal and bearings. It is worth noting that repair procedures must be carried out as quickly as possible, otherwise other components of the washing machine can be damaged, as a result of which the cost of repairing it in the future will increase significantly.
Many models of washing machines have a non-removable tank,
which significantly complicates repair work to replace the oil seal and bearings. In this case, you only need the intervention of an experienced craftsman who can cut the tank and then restore its original integrity and strength.
The counterweights and pulley have become loose
If the washing machine begins to make extraneous noise while draining water, it is necessary to check the fastenings of the counterweights and pulley, as they may become loose due to constant use of the equipment.
If the pulley fastenings are not tightened properly, the washing machine makes noise and characteristic clicks during operation. In this case, it is necessary to check the tightness of all fastenings of the pulley and drum, and, if necessary, tighten them. There is nothing complicated about this, so any home technician can handle this problem. The main thing is not to overdo it, so as not to damage the threaded connections.
The purpose of the counterweight is to balance the drum and give stability to the washing machine during operation. They can be attached using either bolts or self-tapping screws. During operation of the technique, the fastenings may become loose, causing the counterweights to begin to make extraneous noise when the tank rotates.
It is worth noting that the fastenings of the counterweights must be tightened urgently, since during operation, loose elements can cause serious damage to the washing machine. We recommend periodically checking the tightness of all counterweight and pulley threaded connections.
A foreign object has gotten between the tank and the drum
Various small items of clothing, accessories and other small objects located in pockets can get into the space between the tub and the drum during washing and make extraneous sounds when the equipment is operating. In this case, any foreign object must be removed without fail, since it may later cause more serious malfunctions and damage to the washing machine units.
You can get the item after partially disassembling the automatic machine. We recommend contacting a service center, since different models have their own assembly features, which only an experienced technician knows.
- Troubleshooting Methods
- If extraneous sounds occur while draining water from the washing machine, it is necessary to urgently look for the source of the problem, since further operation of the equipment can only aggravate the breakdown and increase the cost of future repairs. Minor faults, such as cleaning the drain filter, can be corrected yourself. We strongly recommend that you trust repairs of larger problems only to highly qualified technicians from specialized service centers.
- Prevention of breakdowns
- Simple recommendations will help to completely eliminate the appearance of third-party sounds during the operation of washing equipment and significantly increase its service life:
- Any washing machine requires mandatory maintenance.
Constant overload of the drum is unacceptable.
It is necessary to use special chemical compounds that reduce water hardness.
Clean the drain filter periodically.
