Washing Machine Leaking Water? Here's Why

A washing machine leak can range from a small puddle under the machine to a full-scale floor flood. Some causes are easy to fix yourself; others require a technician or replacement. Here are the seven most common causes.

1. Leaking from the Door (Front Loaders)

The most common leak point on front loaders is the door seal (gasket). Over time, the rubber seal can tear, become mouldy, or accumulate debris that prevents a proper seal.

Check: Run a cycle and watch the door seal carefully. Look for small tears, mould patches, or foreign objects (coins, bra wires, socks) trapped in the seal fold.

Fix: If the seal is undamaged, clean it thoroughly with a cloth and mild detergent. If torn, the door seal can be replaced — this is a relatively affordable repair ($80–$150 for parts and labour).

2. Inlet Hose is Loose or Cracked

The cold (and hot, if applicable) water inlet hoses connect to the wall tap. If these hoses are loose, cracked, or the rubber washer inside the connection has degraded, they'll leak.

Check: Inspect both hose connections at the tap end and at the machine end. Feel for moisture. Look for cracks or discoloration in the hose itself.

Fix: Tighten connections by hand (don't over-tighten). Replace degraded washers (they cost less than $5 at a hardware store). Replace the entire hose if cracked — never risk a burst hose as it can cause major flooding.

3. Drain Hose is Loose or Kinked

The drain hose runs from the pump to the standpipe or laundry tub. If it's not seated properly, it can let water escape during the pump-out phase.

Check: The leak will occur during or after the spin cycle when the machine pumps out. Check the drain hose connection at the machine and at the wall.

Fix: Reseat the drain hose and ensure the standpipe connection is secure. The hose end should sit inside the standpipe, not resting against the outside.

4. Too Much Detergent

Excess detergent creates excessive foam. This foam can overflow from the drum and leak out the front door seal, the dispenser drawer, or even the pressure sensor hose.

Check: If the leak is soapy and foamy, this is almost certainly the cause.

Fix: Use less detergent. For front loaders, use HE (high efficiency) detergent and use the recommended amount only. Run a rinse-only cycle to clear excess soap.

5. Dispenser Drawer is Blocked

Detergent and fabric softener residue can build up in the dispenser drawer and block the outlet, causing water and detergent to overflow out the front of the drawer.

Fix: Remove the drawer completely (usually by pressing a tab while pulling), soak it in warm water, and scrub with a brush to clear all residue. Clean the drawer housing too.

6. Pump Filter is Blocked (Front Loaders)

Front loaders have a pump filter (usually accessed via a small panel at the front bottom of the machine). When this is blocked with lint, coins, and debris, it can cause a backup leak from the filter housing.

Fix: Place a towel under the filter, unscrew it slowly, and let the water drain out gradually. Remove all debris and clean the filter housing. Screw back firmly.

7. The Drum Bearings are Failing

If your machine is very noisy during spin and also leaking from the bottom, the drum bearings may be failing. When bearings go, they can allow the drum to shift and damage the drum seal, causing leaks.

Diagnosis: Spin the drum by hand with the machine off. It should feel smooth and quiet. Grinding or rumbling suggests bad bearings.

Repair vs Replace: Bearing replacement is an expensive repair ($250–$450). On machines over 8–10 years old, replacement is often more economical.

When to Replace

If your washing machine is leaking due to a faulty pump, failed drum seal, or significant mechanical failure and it's over 8 years old, a replacement often makes more financial sense than a costly repair.
