Have you ever wondered how your washing machine maintains stability while spinning and tossing your clothes? The counterweight, a vital component, holds the key to the solution. This component is crucial for maintaining the machine’s balance, particularly during high-speed cycles that could otherwise result in excessive vibration or shaking.
But what material makes up a counterweight exactly? For this reason, the majority of washing machines use bulky materials like cast iron or concrete. The base of the machine frequently has concrete blocks inserted into it to provide the weight needed to keep everything steady. Due to their density, cast iron weights, which are used in certain models, are just as effective.
You can better appreciate the engineering that goes into your washing machine if you know what the counterweight does and how it is made. It’s a little but powerful part that makes sure your washer runs smoothly and silently, which eventually lessens the hassle of laundry day.
| Material | Description |
| Concrete | Heavy and durable, often used to stabilize the washing machine during operation. |
| Cast Iron | Sturdy and weighty, helps to reduce vibration and movement. |
| Steel | Strong and solid, provides good balance while the machine is running. |
| Plastic | Lighter than other materials, sometimes used in modern machines to reduce overall weight. |

Counterweight material
Almost all washing machines had steel blocks or cast iron counterweights when they were first introduced, probably 20 to 30 years ago. Take Vyatka-automated washing machines, which were manufactured in the early 1990s. As of right now, only high-end Swedish and German equipment has metal weights.
Today, concrete counterweights are found in 98% of washing machines.
Although concrete weights are significantly less expensive than metal ones, they are not as strong as cast iron or steel blocks. This lowers the price of contemporary washing machines. The primary drawback of a concrete counterweight is its rapid wear, while its price is an advantage. Vibrating under a concrete counterweight causes it to break down over time. Additionally, they are always found inside a washing machine that is in use. As a result, the weights start to develop cracks that get bigger over time.
During the subsequent wash, a cracked concrete counterweight may easily break into multiple pieces and fall. Certain internal components of the automatic machine, such as the interference suppression filter, pressure switch, hatch locking mechanism, and so on, will undoubtedly "touch" some of the falling fragments. It will be necessary to remove "collateral" damage in addition to changing the weight.
It is evident that washing equipment is not the ideal use for a concrete counterweight. However, producers will persist in outfitting machinery with these blocks for an extended period of time, in an effort to produce automated devices at the lowest feasible cost.
If the counterweight needs to be replaced, you can handle the task without a professional’s assistance.
A specialty store will sell new weights that are specific to the washing machine model. We’ll walk you through disassembling vintage counterweights.
Location of counterweights
Locating counterweights in an automated machine is a very simple task. The simplest method for reaching the higher weight. But there are always more issues when removing this block. In order to "get to" it, you must:
- de-energize the automatic machine;
- close the shut-off valve responsible for the water supply;
- move the washing machine away from the wall to have free access to all sides of the case;
- use a screwdriver to unscrew the two screws holding the top panel of the machine;
- remove the case cover, to do this, move it slightly back and lift it.
You’ll notice the upper counterweight right away. It is essential to check the unit for flaws. Subsequently, you must evaluate the state of the front weights; to do this, you must remove the case’s front wall. The following will be the subsequent action algorithm:
- pull out the powder receptacle;
- unscrew the bolts located along the perimeter of the control panel;
- unhook the "dashboard" from the case and carefully place it on the machine so as not to damage the wiring;
- dismantle the lower false panel, behind which the garbage filter is hidden, by hooking it with a screwdriver;
- open the hatch door wide open;
- hook the outer clamp holding the drum cuff with a screwdriver and remove the ring;
- tuck the sealing rubber inside the drum;
- slightly tilt the machine case back, put your hand between the tank and the front wall, feel the UBL and disconnect the plug with the blocker contacts;
- unscrew the screws holding the front wall;
- remove the front panel.
You can now examine the counterweights up front. You will need to replace the elements if there are numerous cracks in them. To create space for new blocks, we will demonstrate how to remove damaged concrete weights.
A washing machine’s counterweight is essential to maintaining the stability of the device while it is in use. Constructed from materials such as cast iron or concrete, it aids in machine balancing and vibration reduction.
Gaining knowledge about the composition of the counterweight can help you better understand how your washing machine works. This easy-to-use yet efficient solution guarantees that your laundry gets done quickly and quietly, without the machine bouncing around or creating excessive noise.
Understanding the counterweight is a minor but crucial component of the puzzle, regardless of whether you’re thinking about fixing your washing machine or are just inquiring about how it operates.
In terms of washing machines, the counterweight is essential to maintaining the machine’s balance and steadiness while it is in use. These counterweights are usually constructed from substantial materials, such as cast iron or concrete. Their primary function is to counterbalance the rotating drum in order to minimize undue movement and vibration. Gaining an understanding of the materials used to make these counterweights can help you appreciate the engineering that goes into making a stable, effective washing machine that lasts longer and runs smoothly.
