We’ve all been there. One minute your washing machine is humming along, the next—you’re standing in a pool of water wondering where it all went wrong. If you’re thinking, “What to do if my washer is leaking from the bottom”, well-you’re not alone. It’s one of the most common sources of domestic water damage, and if not dealt with quickly, it can lead to mould growth, warped floors, and expensive repairs.
In this blog, we’ll walk you through what is causing washing machine leaks, what to do immediately, and why renting a dehumidifier might be the difference when it comes to drying.
Top Reasons for Bottom Leaks on a Washing Machine
Before we dive into repairs, it is helpful to understand why your washer might be leaking from the bottom:
- Worn or damaged water inlet hoses
- Damaged or loose drain hose connections
- Blocked or damaged pump or drum
- Overloaded machine causing door seal to fail
- Residue or limescale build-up that leads to clogs
Tip: Remove your machine and look for indications such as green slime, calcium deposits, or water spots at the back of the unit.

What to Do Right Away if Your Washer Leaks
When your washer leaks, it is crucial to act quickly. Follow these steps:
- Shut Off the Water Supply
Find the valve that is behind the washer and shut it off. If this does not work, turn off your house’s main water supply.
- Unplug the Appliance
Prevent any electrical shocks by turning the power off at the socket.
- Mop Up the Water
Suck up all the water you can with mops, towels, and buckets. If you have a wet vacuum, great.
- Open Doors and Windows
Ventilation will help the drying process and prevent musty smells from developing.
- Clean the Damaged Area
If the leak is from the supply hose, the water is usually clean (“white water”).
If from the drain hose, it’s “grey water” and may contain dirt or grease. Disinfectant or antimicrobial cleaner will kill germs and remove odours.

This is where it gets serious. Surface water can be mopped away, but water can get trapped under floors and behind walls—and that’s when mould starts.
Will a dehumidifier help with mould?
Your drying plan will depend on your flooring:
- Solid Concrete Floors
Replace tiles, lino, or laminate if it’s retaining moisture
- Install a fan and dehumidifier to blow dry air directly onto wet surface
- Timber or Raised Floor Voids
Water may enter voids under floorboards or panels
- You may need to lift sections of floor and duct dry air into void
- Walls (especially plasterboard)
Damp can seep in at skirting and adjacent walls
If plasterboard is involved, think about cutting a hole to create airflow and blow dry air over the wet surface using a fan and dehumidifier
