Why Is My Washing Machine Leaking Water?

A leaking washing machine can go from being a small annoyance to a big problem fast. For London homeowners, where space is tight, and plumbing can be a bit outdated, keeping your appliances in check is important. Whether it’s just a few drops or a full-on flood, sorting out a leak quickly can save you from some seriously expensive repairs.

In this blog, we’ll break down why your washing machine is leaking, how to figure out what’s wrong, and what you can do to fix the issue.

Washing Machine Leaking Explained

If your washing machine is leaking, the first step is figuring out where the water's coming from—that’s the key to fixing it. Below are some of the most common types of washing machine leaking.

Types of Washing Machine Leaks

Washer leaking from door

If your washing machine is leaking from the door, the culprit is usually the door seal. Over time, the seal can get damaged, worn out, or clogged with dirt and grime. When debris builds up, it prevents the seal from closing tightly, letting water escape during a wash cycle.

Washer leaking from bottom

Noticing the bottom of the washer is leaking? There are a few possible causes. It could be a damaged pump leaking water, especially during the spin or drain cycle. Loose or disconnected hoses are another common issue, often caused by wear and tear or incorrect installation. Cracks in the washer’s tub or drain system might also lead to the clothes washer leaking from the bottom.

Leaking from the bottom or sides

If water is leaking out from the bottom or sides, a clogged or blocked drain filter might be the issue. Over time, lint, debris, or small objects can build up and cause water to back up and spill out. Internal leaks from the tub or seals can also cause water to escape in these spots.

Common Signs of a Washing Machine Leaking

Even small water puddles around your washing machine can mean trouble. It might be a leak in the hoses, seals, or even the drum. Ignoring it could lead to bigger headaches down the line.

Spot any rust or weird discolouration? Check the seals, joints, and edges of your machine.

If you leave it too long, it could lead to the washing machine leaking and expensive washing machine repairs you definitely don’t want.

Diagnosing the Leak

Unplug and examine the washing machine:

Start by unplugging your washing machine and shutting off the water supply. Safety first! Once that’s done, pull the machine away from the wall and take a look at the hoses and connections at the back. Are there any cracks, loose fittings, or signs of wear? These could be the culprits behind your washing machine leaking.

Take a look at the door seal:

Open the washer door and check out the rubber seal around it. Feel around gently—any tears, cracks, or gunk buildup? These can let water sneak out during a wash. While you’re at it, grab a damp cloth and give the seal a quick clean to make sure dirt isn’t causing any problems.

Peek underneath the machine:

Check the drain pump, pipes, and the bottom of the machine. Keep an eye out for cracks, leaks, or screws that might need tightening.

Don’t forget the filters:

Find the drain filter, usually at the bottom front of the machine and pull it out. Rinse it well to get rid of any dirt, lint, or debris clogging it up. While you’re at it, check behind the filter for anything stuck in there. Cleaning the filters regularly can save you from washing machines leaking!

Causes of Washing Machine Leaking and How to Fix Them

Understanding why your washing machine is leaking will help you make an informed decision on how to resolve it. Here are a few common causes:

Damaged Seals or Gaskets

The rubber seal around your washing machine door also called the door gasket, is key to keeping water in during a wash cycle. But over time, it can crack or wear out, which often results in the washer leaking from door.

This is especially common if detergent residue builds up or if the machine isn’t cleaned regularly, as the buildup can weaken the rubber and lead to the washing machine leaking.

• Give the door gasket a quick clean now and then to avoid any detergent buildup.
• Keep an eye out for cracks or wear. If it looks damaged, it might be time for a replacement! You can grab a new gasket from the manufacturer or your local hardware store.

Loose or Cracked Hoses

The hoses, like the inlet hose that connects the washing machine to the tap, can loosen or crack with age or frequent use, leading to the washing machine leaking from underneath. If they’re not tightly secured or the rubber weakens, leaks can happen. The inlet hose might leak when water is filling the machine, and the drain hose could cause problems when water is being pumped out.

• Take a quick look at your hoses now and then to check for cracks or if they feel loose. If anything’s loose, just tighten it up.
• If there are any damaged hoses, swap them out for a new one. Make sure to always go for high-quality ones that’ll last longer!

Overloading the washer

Stuffing your washing machine full to the brim might seem like a time-saver, but it’s actually a recipe for trouble. Overloading doesn’t just hurt cleaning performance. It also puts extra strain on the door seals, hoses, and internal parts, making leaks more likely. Plus, the extra weight can cause the machine to shake, mess up its components, and lead to the washing machine leaking.

• Check your washing machine’s manual to see how much laundry it can handle.
• Don’t overstuff the drum—spread your clothes out evenly. It’s easier on the machine and helps your laundry come out cleaner!

Worn Pump or Faulty Parts

The drain pump handles draining water during and after cycles, but over time, it can wear out, crack, or even get clogged with things like lint, coins, or buttons. This can lead to leaks from the bottom of the machine. Other parts like seals, bearings, or valves can also degrade over time and cause your washing machine to leak.

• Clean out the drain pump filter regularly because it’s a magnet for lint, coins, and other debris.
• If the pump is cracked or not working, it’s time for a replacement. Just make sure it’s compatible with your machine’s model.
• Take a look at other parts like bearings, seals, or valves. If they’re worn out, consider replacing them, and don’t hesitate to call a plumbing engineer for help!

Blockages in the Drainage System

If water is pooling under your machine or spilling out onto the floor, it could be a blockage in the drainage system.

These blockages are often caused by lint, detergent residue, or small items like coins and hairpins that sneak in with your laundry.

• Make sure to clean the pump filter and check if anything’s clogging the drain pipe.
• If there’s a blockage in your home’s drainage system, try using a plumbing snake or call a professional plumber to handle it.
• Keep small items like coins or hairpins out of the wash, and use a laundry bag for those tiny things.

Improper Installation

Sometimes, washing machine leaking isn’t about wear and tear—they’re about how your machine was set up. Loose water connections, improperly placed hoses, or even an uneven machine can cause water to escape. Make sure that your washing machine installation is carried out according to the manufacturer's instructions, and double-check that everything is secure.

• Make sure the hoses are correctly connected and in the right spot.
• Use a level to check that your washing machine sits evenly on the floor.
• Take a quick look at the installation guide to avoid any setup mistakes.

Incorrect Detergent Type or Quantity

Wrong detergent or too much of it can create too many suds, especially in high-efficiency (HE) washers designed for low-sudsing detergents. Those extra suds can overflow and leak out from the detergent drawer or other parts of the unit, leading to the washing machine leaking. To avoid this, always use the detergent recommended for your washer and measure the right amount.

• Stick to your machine's recommended detergent (like HE detergent for high-efficiency washers).
• Measure out the detergent based on the load size and the instructions.
• If there are too many suds, run a rinse cycle to avoid any leftover residue.

Preventative Maintenance

Don’t wait for a leak to disrupt your day. Take these practical steps to prevent the washing machine from leaking from underneath.

• Wipe the door seal after every use: It only takes a minute to grab a damp cloth and clean around the door seal. This keeps dirt, detergent build-up, and mould at bay to prevent the washer from leaking from the door.
• Check the filters once a month: Filters love to trap lint and debris, so take a quick peek every few weeks. Clearing them out keeps the drainage flowing and avoids any pesky blockages.
• Pay attention to Seasonal care: London’s chilly winters can mess with your washer. Check hoses and water connections during colder months to make sure they’re secure and haven’t cracked from freezing temps.
• Don’t overload: Stick to your washer’s capacity guidelines. Overloading can stress the machine and leave your clothes less clean.

When to Call a Professional?

Some washing machine leaks are easy to fix yourself, but there are some issues that need a professional touch. If you’ve tried the basics and the leak won’t stop, or if it’s a big one and seems like a more serious issue—it’s time to call in an expert.

Here are a few situations where it’s better to get help:

• Internal Water Leaks: If water is pooling under the machine and you can’t figure out why, it’s probably an internal issue that needs professional repair.
• Electrical Problems: Got signs of sparks, burning smells, or shocks? Unplug the machine right away and call an electrician.
• Unsure What’s Wrong: If you’re not sure what’s causing the washing machine to leak or don’t feel confident trying to fix it, it’s always safer to leave it to a pro.

When in doubt, it’s better to be safe than sorry!
