It can happen that a washing machine no longer drains, that is to say that water remains in the tub after the wash cycle is finished. In this case, something is preventing water from draining from your device. The origin of this failure may come from an installation or maintenance problem, or from a defective spare part.
You will have to carry out several tests and checks in the different elements of your machine. If the problem persists, you will need:
- empty the remaining water,
- check drain filter
- check the tank hose and the drain pipe
- check the vent
- check the drain pump and test its power supply
- check the electronic board.
Discovering that your washing machine is no longer draining or emptying properly can be a frustrating experience. Standing water in the drum or a failure to complete the drainage cycle can prevent your laundry from getting properly cleaned. There are several potential reasons why a washing machine may encounter drainage issues, and understanding these causes can help you troubleshoot the problem and find a solution. In this article, we will explore the common reasons why a washing machine may no longer drain or empty, and provide possible solutions to address the issue.
1. Clogged Drain Hose
A clogged or partially obstructed drain hose is one of the most common causes of drainage problems in a washing machine. Over time, lint, debris, or other objects can accumulate and block the flow of water through the hose. To resolve this issue, start by checking the drain hose for any visible blockages. If you find any obstructions, carefully remove them and clean the hose thoroughly. If the clog is severe, you may need to disconnect the hose from the machine to clean it more effectively.
2. Blocked Pump Filter or Coin Trap
Washing machines often have a pump filter or coin trap that collects debris such as lint, coins, and small objects. If this filter becomes clogged, it can impede the water drainage from the machine. Locate the pump filter, which is usually located at the front or bottom of the machine. Follow the manufacturer’s instructions to remove and clean the filter. Clearing any debris or obstructions from the filter should help restore proper drainage.
3. Pump Failure
If the drain hose and pump filter are clear, but your washing machine is still not draining or emptying, it’s possible that the pump itself has failed. The pump is responsible for pumping water out of the machine during the drainage cycle. A malfunctioning pump will need to be replaced to restore proper drainage. It is recommended to seek the assistance of a professional technician to diagnose the pump and carry out any necessary repairs or replacements.
4. Incorrect Installation of Drain Hose
Improper installation of the drain hose can lead to drainage problems. The hose should be securely attached to the washing machine and properly positioned to ensure smooth water flow. Verify that the drain hose is not kinked, twisted, or too far inserted into the drain pipe. Additionally, ensure that the height of the drain hose is within the recommended range specified by the manufacturer, as an incorrect height can result in siphoning or backflow issues.
5. Drainage System Blockage
If multiple plumbing fixtures in your home are experiencing drainage problems, there may be a blockage in the main drainage system. In such cases, it is advisable to contact a professional plumber to inspect and clear the blockage from the main drain line.
It is possible that on some appliances your drain pump is connected to a vent. It is a black hose that makes the connection between the drain pump and the product box.
To access this part, simply remove the left side and the top, then disconnect the hose at the pump. Blow inside and see if it is blocked.
Here are some troubleshooting steps you can take to address a washing machine that no longer drains or empties:
- Check the drain hose for blockages and clean it if necessary.
- Locate and clean the pump filter or coin trap to remove any debris.
- Ensure that the drain hose is properly installed, without any kinks or obstructions.
- Verify the recommended height of the drain hose and adjust it if needed.
- If none of the above steps resolve the issue, contact a professional technician to inspect and repair the pump or any other potential mechanical problems.
It is important to exercise caution when working with a washing machine’s drainage system. Always disconnect the power supply and refer to the manufacturer’s instructions before attempting any repairs or maintenance.
In conclusion, a washing machine that fails to drain or empty properly can be caused by various factors, including a clogged drain hose, blocked pump filter, pump failure, incorrect hose installation, or a blockage in the main drainage system. By understanding these common causes and following the troubleshooting steps mentioned above, you can often identify and address the issue effectively. If the problem persists or if you are unsure about any repairs, it is advisable to consult a professional technician to diagnose and repair the specific problem with your washing machine’s drainage system.
