There are few things worse than starting a load of laundry only to return a few hours later to puddles of water spread across the floor. Whether your washing machine is new or old, leaks can happen. When they do, it’s important to quickly assess what the causes are and correct them to ensure that further damage doesn’t occur.
Reasons That May Cause a Leaking Washing Machine
Although there are a wide variety of reasons as to why you’re experiencing a washing machine leak, here are the most common items for you to be on the lookout for.
1. Loose or Missing Hose Clamp
The drain hose is responsible for ensuring that water safely and securely exits the machine, and it’s the hose clamp that must be tight so as to prevent water from slipping through as it circulates.
If your hose clamp connection feels or appears loose, try tightening it to prevent water from leaking through. If that doesn’t work, you may need to call in professional support.
2. Broken or Faulty Tub Seal
The tub seal is an important piece in keeping your machine’s transmission operating effectively, and if it appears that leaking occurs during a rinse cycle, it’s likely that your tub seal is in need of repair or replacement. Tucked away on top of the transmission itself, you’ll need to remove the spin basket and, in some cases, flip the machine over. That said, it’s recommended that you seek professional support for this replacement.
3. Clogged Catch Basket or Filter
Your washing machine catch basket is similar to your dryer’s lint trap. Over several uses, it can become clogged and cause fibres to build up in the machine, leaving residue on your clothing and, oftentimes causing the washer to leak. To fix this problem, simply remove the catch basket – found easiest by referencing your ownership manual – and clear it out.
4. Broken or Cracked Coupler
The coupler is a plastic seal placed between the motor and drum of your washing machine, designed to crack in instances of increased pressure. If the coupler does crack – which will often save the much more expensive machinery from getting damaged – it can cause leaking underneath. That said, it’s a fairly affordable and simple item to replace.
5. Faulty Water Pump
More often than not, a washing machine leaking water will be due to a damaged water pump or compromised water pump hose connection. Symptoms of a faulty pump include loud rumbling or shaking from the machine during a wash cycle.
You can access the water pump through the bottom of the machine to assess its condition, as well as the condition of the hoses connected to it, and determine the work needed.
What to Do If Your Washing Machine Is Leaking
Shut off the water supply to stop the flow.
- Unplug the machine to avoid electrical hazards.
- Contain the leak using towels or a wet/dry vacuum.
- Call a professional if the source isn’t obvious or if parts need replacement.
