Why Is My Washing Machine Leaking?

Jul 18, 2023, 15:51pm

Your washing machine generally leaks when the sealing of one of the elements of your appliance no longer has an effect (hoses, detergent drawer, hoses, porthole, etc.). Some parts can wear out over time, such as hoses and water connection circuits.

Depending on the origin of the leak, it will be necessary to check the elements linked to it:

  • Check the tap and siphon
  • Check the drain filter cap
  • Check the product box
  • Check the tightness of the tank seal
  • Examine the hoses
  • Check the check valve
  • Check the tightness of the drum bearing
  • Check your tank

Your washing machine can also leak if there is too much detergent: excess suds can cause the detergent box to overflow. Start by looking through the window and observing whether or not there is excessive foam when the machine is running.

Discovering that your washing machine is leaking can be a frustrating and potentially damaging situation. A leaking washing machine not only causes water damage to your floor and surrounding area but also interrupts the cleaning process. There are several potential reasons why a washing machine may develop leaks, ranging from simple issues to more complex problems with internal components or connections. 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 leaks and provide possible solutions to address the issue.

Why Is My Washing Machine Leaking?

1. Damaged or Worn Out Hoses

One of the most common causes of a leaking washing machine is damaged or worn out hoses. The hoses that supply water to the machine and drain water away can develop cracks, splits, or loose connections over time. Inspect the hoses for any visible signs of damage or leaks. If you detect any issues, replace the faulty hoses with new ones to ensure a secure and watertight connection.

2. Faulty Door Seal or Gasket

If your washing machine has a front-loading design, a faulty door seal or gasket could be the cause of the leak. Over time, the seal or gasket can become damaged, loose, or develop cracks, allowing water to escape during the wash cycle. Inspect the seal or gasket for any signs of wear or damage. If necessary, clean or replace the seal or gasket according to the manufacturer’s instructions.

3. Clogged or Damaged Pump

A clogged or damaged pump can also cause leaks in a washing machine. The pump is responsible for draining the water from the machine during the wash and rinse cycles. If the pump becomes clogged with debris or develops a fault, it may not function properly, leading to water leakage. Check the pump for any obstructions or damage. If necessary, clean or replace the pump to restore proper drainage.

4. Overflowing or Clogged Detergent Dispenser

If your washing machine has a detergent dispenser, overflowing or clogging of the dispenser can cause leaks. Excessive detergent or fabric softener can overflow from the dispenser and leak onto the floor. Additionally, clogs in the dispenser can prevent proper water flow and cause water to leak during the wash cycle. Clean the dispenser regularly to remove any residue or obstructions, and ensure that you use the appropriate amount of detergent and fabric softener.

5. Loose or Faulty Connections

Loose or faulty connections within the washing machine can also contribute to leaks. Inspect the connections between the water inlet and outlet, as well as any other internal connections, for any signs of looseness or damage. Tighten loose connections or replace faulty parts to ensure a secure and watertight seal.


The joint and bearing assembly is called the “drum bearing”. The bearings ensure the rotation of the drum. They are generally protected by a seal which can cause a leak, because they are heavily stressed. It generally wears out due to limescale or repeated detergent overdoses.

Check the condition of the drum bearing seal: if there is rust or whitish marks, the bearing is leaking.

  • On front-loading machines, there is only one bearing located just behind the pulley.
  • For top loading machines, there may be a bearing on each side of the drum.


It sometimes happens that a foreign body comes to pierce the tub, generally during the spin cycle when the tub is rotating at a very high speed. This is one of the reasons why it is very important to check the pockets of clothes before putting them in the washing machine.

  • Open your device. Dismantle the side walls and the one on the top and the back, to see the whole contour of the tank.
  • Visually check the condition of your tank, there should be no holes or cracks. A very fine crack is enough to create a leak.

Troubleshooting Steps

Here are some troubleshooting steps you can take when your washing machine is leaking:

  1. Inspect the hoses for damage or leaks, and replace them if necessary.
  2. Check the door seal or gasket for wear or damage, and clean or replace it as needed.
  3. Examine the pump for clogs or damage, and clean or replace it if required.
  4. Clean the detergent dispenser and use the appropriate amount of detergent and fabric softener.
  5. Check for loose or faulty connections and tighten or replace them accordingly.

By following these steps, you can often identify and address the issue of a leaking washing machine. Regular maintenance, proper usage, and attention to the machine’s components and connections will help prevent future leaks.

In conclusion, a washing machine that leaks can be caused by various factors, including damaged or worn out hoses, faulty door seals or gaskets, clogged or damaged pumps, overflowing or clogged detergent dispensers, and loose or faulty connections. By understanding these common causes and following the troubleshooting steps mentioned above, you can often identify and address the issue effectively.
