Why is My Washing Machine Leaking?

A washing machine that has sprung a leak is a fault that ranges in severity, from a minor dribble to an all-out flood.  Usually, leaks can be fixed yourself at little or no cost; you just need to have a methodical approach to finding the source.

Start looking on the outside of the washing machine

Before you start removing the washing machine lid and rear panel first take some time to see if there are signs of water on the outside of the washing machine.

Check the water inlet taps and hoses

The area to start your investigation is at the rear of the washing machine where the water inlet hoses are attached.  With the washing machine running check for water at each end of the inlet hoses.

Washing machine waste pipe blocked?

A common problem in hard water areas where a build-up of limescale can cause blockages in your waste pipe restricting the flow of water to the drain.  Water will back up and overflow the waste pipe causing flooding.  Check the wall area around the waste pipe for signs of water.

Check the soap dispenser

A build-up of powder detergent in the hose that runs from the soap dispenser to the tub will eventually cause a blockage and water would back up and flood from the soap dispenser drawer.

Check the washing machine door

A common area for leaks is the washing machine door.  If it appears that water is coming from the door, check the door seal for signs of damage or perishing.  See our video on how to replace your washing machine door seal if necessary.

Check the door glass; a build-up of limescale on the glass will mean that the door isn’t forming a seal causing water to escape.

Check the washing machine filter

If your washing machine has a removable filter, you will almost certainly find it at the front bottom of your washing machine.  Sometimes it can be hidden behind the plinth.  A damaged or perished filter seal will be enough to cause a leak in this area.  Check out our video on how to clean and replace your washing machine filter.

Leaks from inside the washing machine

Once you have ruled out the leak is coming from outside of the washing machine it will be necessary to investigate the internal hoses and components.  First, it is a good idea to try and understand the approximate location of the leak.  To do this, you can spread some newspaper or cardboard underneath the washing machine, and then turn it on.  The position of the water leak will now be visible and give you a good idea of where to investigate first.

Check the pump and associated hoses

Leaks from the washing machine pump are relatively rare. However, a build of limescale can cause hoses and seals to perish.

Check the internal hoses and plastic components

Any component that is rubber or plastic has the potential to break down and cause a leak.  You will typically see a tell-tale sign that water has leaked around an area.

Nowadays washing machine tubs are constructed of plastic, not metal, and it is not uncommon for a foreign object, such as a coin, to get caught up between the drum and the tub sheering part of the plastic moulding.
