A washing machine must dispose of the used water after its cycle is complete. The drainage system, a crucial element that guarantees your clothes are left clean and prepared for drying, takes care of this duty.
Despite being frequently disregarded, the drainage device is essential to the efficient operation of your washing machine. Knowing how it operates will help you maintain your computer’s efficiency and ward off possible problems.
This post will explain how the drainage system works, what typical issues it may encounter, and how to keep it in good working order.
In order to effectively remove dirty water from a washing machine after each cycle, avoid water pooling, and guarantee that your clothes come out clean, a drainage device is necessary. Knowing how this part functions will make it easier to maintain your machine and increase its lifespan by assisting you in troubleshooting common problems like slow draining or water remaining in the drum.

Elements of the water removal system
The drainage system is really quite basic. The user won’t have any trouble inspecting the machine and identifying the "weak spot" if there are drain issues. We will list the components that make up the unit. Any automatic machine’s regular water tank drainage is caused by the following factors:
- drain pipe;
- pump;
- garbage filter;
- Drainage hose.
In the spent water flow, the drain pipe rises first. It links the pump and tank together. There is a thickening at the start of the corrugation, and a plastic ball serves as a check valve. The "ball’s" job is to keep the sewage system smelling bad and to drains.
The pump, which is made up of an electric motor and a working chamber, is the primary component of the drain system.
The nozzles are attached to the pump’s plastic pump chamber. Pumping a spent fluid is carried out in the instance. The end of the element has a garbage filter inserted to shield the pumping station from foreign objects. The pump engine comprises two cores. This is where it winds. The working wheel is recorded on the rotor, which rotates inside. The pump’s parts are all "hidden" inside a plastic shell. Wiring connection terminals are bred outward.
When it comes to the SMA pump, its typical voltage is 220 V. Depending on the machine model, the pump power can range from 30 to 80 watts. The windings are composed of either copper or aluminum. The element is powered by the main control module.
The pumping station operates on a straightforward principle. Since the pump is positioned below the tank’s level, the working chamber is always filled with water. The motor wheel starts moving when the module delivers voltage. There is pressure in the inlet and a vacuum in the supply pipe. As a result, liquid is pumped out of the tank.
At last, water finds its way into the drain hose. Its two ends are attached to the sewer pipe’s outlet point and the pump’s working chamber, respectively. The drain hose must be connected correctly and placed between 50 and 70 centimeters above the floor. Gravity will cause the water in the tank to drain if you break this rule.
How to check and replace the pump?
Drainage issues with the washing machine could arise after several years of use. The drainage system’s components frequently become clogged. The machine’s functioning can be restored with a quick cleaning. Accidents also occur. For instance, the pipe may crack or the pump may burn out. You will have to change the components in this scenario. You will need to examine every part of the drainage system in order to identify and address the issue.
The lower decorative panel of the case or the service hatch provide access to the drainage system.
A screwdriver can be used to remove the false panel or open the door. Pry off the cover and take care of the clamps. Examine the trash filter and a portion of the drain pump after that. The following will be the sequence of events:
- de-energize the washing machine;
- close the valve responsible for the water supply;
- open the hatch or remove the lower decorative panel;
- find the trash filter;
- cover the floor around the machine with dry rags, place a small container under the washing machine in the area where the filter is located;
- unscrew the plug of the "garbage can" by half a turn. Note that water will flow out of the hole;
- wash the drain filter, clean the seat from dirt;
- shine a flashlight into the resulting hole – this way you can see the impeller of the pump;
- remove the wound debris from the blades;
- using a long stick, try to spin the impeller – it should move intermittently, but freely.
If the impeller is hard to turn, there’s probably something foreign lodged in between its blades. You must take the pump out of the housing in order to clean the element. This is carried out in the manner described below:
- lay the machine on its left side. It is better to cover the floor with something soft beforehand;
- if there is a bottom, unscrew the fasteners and remove it;
- find the pump – it is located immediately under the tank.
It is advised to inspect the pump before disassembling it. A multimeter can be used for pump diagnostics. To accomplish this, attach the tester probes to the element’s contacts, adjust the device to 700 V, connect the machine to the network, and activate the "Drain" mode. You should assess the multimeter’s readings after a few minutes. We can conclude that the pump is defective if it is not humming at 220 volts.
If the pump is not repaired, the element will have to be changed.
Remove the element from the pump, unscrew the bolts holding it in place, and disconnect the pipes and wiring before you can pull it out. Self-tapping screws are used to secure the new component in position, and hoses and previously dropped chips are connected to it.
| Component | Description |
| Drain Pump | Removes water from the drum after each wash cycle. |
| Drain Hose | Carries the water from the machine to the household drain. |
| Filter | Catches debris before it enters the drain pump. |
| Air Gap | Prevents backflow of water into the machine. |
Maintaining the smooth operation of your washing machine is made easier when you are aware of its drainage mechanism. It is essential for draining the water from the drum and leaving your clothes dry and clean.
Common drainage issues can be avoided with routine maintenance, like checking the hoses and cleaning the filter. Your washing machine’s lifespan can be increased with this easy maintenance, sparing you money on expensive repairs.
Understanding how the drainage system functions will help you troubleshoot problems more successfully and maintain a hassle-free laundry routine.
