Tip: Where’s the washing machine leaking from? Bottom leaks may be better identified using a newspaper. Just dry the floor and lay the newspaper beneath the washing machine before you test for leaks. Darkened sections map out your water leak. This method is not always foolproof, however. The best diagnosis will come from a qualified service professional inspecting your machine.

Possible causes |
Signs to look for |
What to do |
|---|---|---|
Leaky pump |
Is the washing machine leaking from bottom in the rear? Note: Some models have pumps in the front. |
You may need a replacement pump. Depending on your make and model, pumps range around $30-$125. Set up washing machine service with a repair professional to have the diagnosis confirmed and a new pump installed. |
Hole in tub |
Do you see a hole anywhere in the tub? |
Constant imbalance can rub a hole in the tub, and holes cannot be patched. You can replace the tub, but a new tub is expensive—around $550 for a complete tub assembly for some models and around $275 for the inner tub only, and that doesn't include the installation. Consider purchasing an entirely new washing machine if you are ready. |
Rusted tub |
Is the tub rusted through in any spots? |
A rusted area that is contributing to small leaks cannot be patched. You may need to replace the tub or buy an entirely new machine. Before you make a decision, check to see if your rusted-through tub is covered under warranty. Rusted tubs that are not covered may need to be replaced, but you will likely find it more economical to purchase a new washing machine than to buy a replacement tub. |
Rusted tub seals |
Rust around the tub seals may be allowing water to drip from the washing machine. Do you see water collecting around the bottom of the washer when the fill starts? |
Tub seals are bolts with rubber and metal washers that secure the outer tub of your washing machine to the cabinet. Rust can often develop around the seals, causing leaks. Have a qualified repair professional determine the level of damage. If the rust is minimal, a new oversized seal should fix the leak. But if the rust is all around the bolt, you'll need a new washing machine. Tub seal parts are relatively inexpensive—seals go for around $10 each and tub seal kits can be purchased for around $75 online—but replacement is tricky, so expect to pay for the time and expertise it takes to install them. |
Faulty center post gasket (top-load washers) |
Does the leak only occur when the machine agitates? |
Arrange for washing machine service to have the center post gasket replaced. It is also a good time to have the air dome seal replaced as well. These aren't expensive parts: A center post gasket can be purchased for about $10 and the air dome seal is even less. But installation can be complicated, so leave this one to the experts. |
Faulty air dome seal |
Does water run out from beneath the side edges of the washing machine? |
The air dome on a washing machine uses air pressure to signal the washing machine about the progress of the wash cycle. A faulty seal can lead to leaks. Schedule washing machine repair service to replace the air dome seal. Replacement is complex, but the part itself can be purchased for less than $10. |
Faulty agitator seals (top-load washers) |
|
If the leak occurs in the middle and when the machine agitates, you will need to replace the spin tube seal on the agitator. While not a pricey part, replacing the spin tube seal can require special tools. It's a job best left to the experts. If the leak appears in the middle and you find grease on your clothes after a wash, you will likely need to have the agitator shaft seal replaced. As with the spin tube seal, the part isn't expensive but replacing it can be complicated. Call in a qualified washing machine repair expert. |
Still seeking a solution? Schedule washing machine repair service with a qualified professional.
Note: Sometimes, what may seem like a washing machine leaking from bottom locations is actually one that leaks slowly from other spots. Slow leaks can accumulate beneath your washing machine making it seem like you have a bottom leak. See our troubleshooting guide to a washing machine leaking for more possible causes.
How to prepare for your washing machine service appointment
Leaks that appear to come from the bottom of a washing machine indicate a problem with an internal component, so be prepared for your service professional to open the cabinet and the top of your washing machine in order to fix it. You can help prepare for the repair by clearing access to the washing machine as much as possible, emptying it of water and clothing, and wiping up any leaks.
If you've tried the newspaper test (at top), be sure to let your service professional know the results.
Dealing with washing machine leaks
Has your leaky washing machine left you with a wet floor? If the spill is contained on hard flooring, the solution is as simple as grabbing some old towels and getting busy.
But if the water has oozed over to any carpeted area, it's imperative to act fast before the carpet backing is soaked.
If water has spread to carpet:
-
Throw clean towels over the wet carpet and walk around on them. This should soak up some of the excess moisture.
-
If you have a wet/dry vac, use it to suction out as much water as possible.
-
Direct a box fan toward the wet area.
If the carpet remains wet despite these efforts, it has been deeply soaked and you'll have to employ more extreme remedies. Pull back the carpeting and cut away the wet backing and replace it with new. Then, rent a professional drying fan to eliminate the last of the moisture.
Repair or replace?
Unless the tub needs replacing, repair of your leaky washing machine will probably make economic sense. But what if the repair is pricey but still cheaper than a new washer? Consider these factors when deciding whether to repair or replace:
-
Age. Washing machines last about 12 years on average. If yours is getting up there, it may be time to consider a replacement, especially if you've had your eye on a new model. Of course, if you love your old washing machine or have a high-end model, you'll have more incentive to consider repair.
-
Efficiency. Newer models use less water and energy. The saving can add up, especially in drought-prone areas where water is especially expensive. If you do shop, look for models with the Environmental Protection Agency’s Energy Star label. They use about 30% less energy and half the amount of water of regular washers. -
Size. Don't overlook what can be an important consideration. Newer washers tend to be bigger than earlier models. If you have an older home with a small laundry room, it might be tricky to find a replacement that will fit the space. Shop before you give up on your old appliance.
-
Features. New washing machines range from about $400 to more than $2,000. If you're content with a simple model, buying new can be an economical choice. If you want your new machine to have all the bells and whistles, you'll need to factor in that cost.

Service pro's plea: If in doubt, stay out. Don't risk causing more damage to your product (or yourself!) by attempting to fix it on your own. It's also easier and quicker for a service technician to diagnose and fix a problem when the product is assembled. In the end, you'll save time and money.
