A washer leaking from the bottom is a common problem for homeowners. If ignored, it can cause water damage, mold, and expensive repairs. Luckily, most machine leaks come from a few common problems that you can often fix yourself.
The main causes of bottom leaks are a loose or damaged drain hose, a broken drain pump, or a worn-out tub-to-pump hose.The drain hose carries water out of the washer, while the drain pump removes water from the tub during the spin cycle. The tub-to-pump hose connects these two parts. If any of these parts crack, get punctured, or come loose, water can leak from the bottom of the washer.
A leaky washing machine can be a real headache, but it doesn’t have to mean a costly repair. In this article, we’ll explain the most common reasons for a washer leaking from the bottom and how to fix them.
How to Troubleshoot a Washer Leaking from the Bottom
There are many causes of leakage in washing machines. Here are some of the common causes of leaks and how to fix them:
Loose or Faulty Hose Clamp
The drain hose of your washing machine connects to the drainage pipe extending from the washer. A clamp secures this connection, some washer models might have this clamp hidden inside, but it’s usually on the outside and easy to spot.
If you notice water leaking from your washer, it could be due to a loose connection or a missing clamp. Check if the hose is connected tightly enough to the drainpipe or if the gasket needs replacing. Both problems can be resolved by hand-tightening the hoses or replacing the faulty part.
Broken Tub Seal
If water is leaking from your washing machine during the rinse cycle, the tub seal is likely broken or damaged. The tub seal is a rubber ring located around the drum. It’s job is to prevent water from leaking out during the wash cycle. If the seal breaks or gets worn out, water can escape from the bottom of the washing machine.
To fix it, unplug the washer from the power supply and turn it over onto its top. Take off the outer cover to access the drum area. Inspect the tub seal for any cracks, tears or damage. If it looks bad, you need to replace it with a new tub seal.
You may be able to temporarily fix it by tightening the existing seal, but to properly stop leaks from occurring, you should install a new tub seal.
Faulty Pressure Switch
A faulty or damaged pressure switch can cause leaking from the bottom of your washing machine. The pressure switch in your washer is responsible for measuring the amount of water entering the drum, if the switch is broken, water could overflow while running a cycle.
To fix this, check the pressure switch on the control panel of the washer and see if it needs replacement. Also check the connecting wire, connecting the switch to the water supply and replace it if damaged.
Faulty Detergent Drawer
The detergent drawer can also cause leaks and overflows if faulty or damaged. If the detergent drawer of your washing machine is leaking, it can cause rust to accumulate around the area leading to further damage of the machine. Check the detergent drawer for any signs of rust or leakage and fix it.
Faulty Door Seal
There are many reasons why your washing machine might be leaking from the bottom. One common cause is a broken door seal, which is easy to spot and fix. Most leaks happen because something is stopping the front door from closing all the way, like dirt or too much detergent.
If the door seal is broken, replace it with a new one. Contact the manufacturer or brand for help and make sure you get the right seal for your machine.
Defective Coupler
A broken coupler can cause water to leak from the bottom of the washer. One of the major signs of a defective coupler is when your clothes are still soaked even after a cycle. The coupler is a rubber-like seal that is designed to break if there is a malfunction to save the machine from being totally damaged. To fix this, check the condition of the coupler and replace with a new one if necessary.
Clogged Catch Basket or Filter
The catch basket in your washing machine is like the lint trap in your dryer. It removes lint and hair from your clothes to ensure your clothes are properly clean. If the catch basket get clogged, it can cause fibers to stick to your clothes, and also cause leaks.
You can find the catch basket in one of three places; on top of the drum, near the agitator, or at the end of the drain hose. If you cannot it in these locations, then your washer might be a new model without a catch basket. Clean out the catch basket regularly to avoid lint buildup or leakages.
Faulty Water Pump
Water leaks usually occurs in washing machine when there is a problem with the water pump. If you hear loud noises and shaking coming from the washer during a wash cycle, the pump may be the problem.
In most models, the water pump is located at the bottom of the washer, attached to two big hoses. If the pump is broken, or the internal hoses are clogged, water can leak from the bottom of the washer.
Check the water pump for any signs of damage or wear and replace it if necessary. Also check the hoses connected to the pump to see if they are clogged or loose and fix them.
Broken Water Inlet valve
Whenever there is a problem with the inlet valve, water leaks tend to happen. The water inlet valve is responsible for bringing water into the washer. If this valve is loose or broken, water will leak continuously from the bottom.
If you encounter this type of problem, unplug the washer and tighten the inlet valve at the bottom. If the valve isn’t tight enough, water can leak out. Remember to clear any dirt, debris, or build up blocking the valve before closing it. If water continues to leak, consider replacing the inlet valve.
Faulty Gaskets
Another common causes of water leaks in washing machine is a faulty gasket. Gaskets are meant to stop water from getting inside the washing machine’s cover and outer parts. However, when it wears out, water will start to leak from the washer.
To fix this, take out the front cover of the washing machine and tighten the bolts of the gasket. If the damage on the gasket is severe, you may need to replace it with a new one.
How to Prevent Leaks in Washing Machine
A leaky washer is something every homeowner’s dreads. To avoid encountering a leaky washer, follow these tips:
Cut back on Detergent
Using too much detergent in your washing machine creates a sticky residue that can build up in the overflow tube of the washer, causing blocks and leaks. To avoid this, use the recommended amount of detergent on the box or bottle for each wash.
Reduce Load Size
Do not put too many clothes in the washer during the spin cycle. This will overload the machine and cause it to shake a lot during the spin cycle. This imbalance and overload can cause wear or damage on the hoses and connections leading to leaks. Keep the load small, and ensure the washer is balance before running a cycle.
Add a Lint Catcher
Lint can build up in the washer’s drainpipe, causing clogs and overflows. Install a mesh lint catcher at the end of the drain line, and clean or replace the lint catcher every month.
Frequently Inspect Hoses and Connections
The hoses and connections all operate under pressure, which can cause them to crack or break over time. Inspect the hoses and connections frequently to prevent leaks. Tighten all loose hose connections and replace any worn out or damaged hose as soon as you notice them.
Install a flood sensor
A flood sensor detects leaks and help prevent room flooding. If the sensor notice water where it shouldn’t be, it will sound an alarm or turn off the power to the washing machine in some cases.
Bottom Line
When you’re running a load of laundry, the last thing you want to see, is your washer leaking from the bottom. Although it may be frustrating, with a little troubleshooting, you can fix the problem and get your washer running smoothly once again. If the leaks persist after carrying out these steps, contact a technician or expert for assistance.
