Is your top-loading washer leaving puddles on the floor after every cycle? If so, a damaged outer tub may be the cause. The good news is that you do not need to call an expensive repair technician right away. With some time, basic tools, and the right replacement part, you can replace the outer tub yourself and stop the leaks for good.
Understanding the Washer’s Inner and Outer Tubs
Inside a washing machine, the drum assembly contains two main parts.
- Inner tub: Usually made of metal or ceramic. This is the perforated drum that holds your clothes during the wash, rinse, and spin cycles.
- Outer tub: A large and sturdy plastic shell that surrounds the inner tub. It keeps water contained inside the machine.
When the outer tub develops cracks or holes, water escapes during almost every cycle and often leaves a large mess. Fortunately, replacing this component is straightforward once you know how to access it and what to look for.
Diagnosing a Damaged Outer Tub
Washers can leak for several reasons, but when the outer tub is compromised, the leaking is usually consistent. To confirm that this part is the source of the problem, you will need to open the washer cabinet and look directly at the tub.
Check for the following:
- Cracks in the plastic
- Puncture marks
- Chewed or worn areas
- Any visible holes or splits
If you see signs of damage, it is time to replace the outer tub.
Common Causes of Outer Tub Damage
Two frequent sources of trouble include:
- Hard debris: Coins, small rocks, and other overlooked items can bounce around during wash or spin cycles. They can strike the outer tub with enough force to crack it.
- Rodents: Mice and other small animals sometimes chew through the plastic and create openings that lead to heavy leaking.
Tools You Will Need
Gather these items before you begin so the repair process goes smoothly.
- Compatible replacement outer tub
- New center tub seal gasket if your replacement tub does not include one
- Flathead and Phillips screwdrivers
- Quarter-inch socket or nut driver
- Seven-sixteenth socket with long extension and ratchet
- Hammer
- Spanner or tub nut wrench
- Pliers or channel lock pliers
- Several towels
- WD 40
- Work gloves
Safety Considerations Before Starting
Replacing an outer tub requires lifting, prying, and working around electrical components. Safety should come first every time you work on a washer.
Important points to keep in mind:
- Disconnect the washer from power before touching any internal parts
- Shut off both hot and cold water valves
- Keep the work area dry to reduce the risk of slipping
- Wear gloves to protect your hands from sharp edges and rough plastic
- Use eye protection when working near springs and metal clips
- Keep children and pets out of the work area
- Place the washer on a stable surface to prevent unexpected movement
- Avoid using worn or damaged tools
- Keep track of removed parts to avoid losing fasteners or brackets
How to Choose the Right Replacement Outer Tub
Not all tubs fit every top-loading washer. Selecting the correct part helps the repair go smoothly and prevents repeat leaks.
Consider the following:
- Match the model number printed on the washer’s tag
- Confirm compatibility with the brand’s parts listings
- Compare the shape and size of your original tub
- Check whether the replacement includes a center tub seal
- Look for manufacturer-specific mounting features
- Read customer reviews for longevity and fit
- Confirm that the replacement material matches the original
- Review return policies in case the part does not fit
- Purchase from a reliable supplier to avoid counterfeit components
