If you asked homeowners about their “most dreaded plumbing nightmare,” leaks would likely top the list. Dealing with a leak means fixing or replacing a faulty hose or pump and addressing the “collateral damage,” aka mold, wall, or flooring damage. 

One typical example is a washing machine leaking from the bottom, which can become even more concerning if your laundry room is upstairs. If not addressed promptly, such a leak can quickly escalate from a minor inconvenience to a full-blown household crisis. If you are in such a situation, it’s time to take action.

In this post, we’ll provide step-by-step guidance on how to fix a washer leaking from the bottom, including seven essential and easy tips to prevent similar scenarios in the future. Roll up your sleeves, and let’s dive in.

Dealing with a Washer Leaking from the Bottom? Follow these Steps to Resolve the Issue

Step 1 - Identify the Leak Source 

The first step in solving a washing machine that leaks from the bottom is to identify the source of the leak and determine at which stage of the cycle the leakage occurs. The leak could manifest during the cycle’s fill/agitation, spin, or drain phases. Nevertheless, a common reason for bottom-leaking washing machines is a leak in the external drain hose.

Taking the time to pinpoint the origin of the issue accurately will save you valuable time and effort, as each “leakage source” demands a different repair strategy. Resist hastily disassembling the washing machine or opening the access panel until you’ve precisely identified the leak’s source.

Step 2 - Inspect Parts & Tackle the Issue

Once you identify the leak source, it’s time to inspect the relevant components that could be causing the problem based on findings from the previous step and apply the appropriate repair method.

• Leaks Occurring during the Fill/Agitation Stages: A damaged tub seal could be the root cause. To verify, run a small load and observe if the washer fills to the proper level.
  • If the water level is correct, the tub seal likely needs replacement. Because the disassembly required is complex, it is advisable to seek professional assistance.
  • If the water level is incorrect, the issue may lie with the water level switch, necessitating professional repair or replacement.
  • Note that the tub seal location differs between front-loading and top-loading washers.

• Leaks Occurring during the Spin Stage: The issue could be an unbalanced washer. First, check if the washer is level and adjust the leveling feet until it is.
  • If balanced but still leaking, inspect the water pump, drain hoses, and seals between the drain hose and pump. 
  • The tub cover gasket may malfunction for top-loaders spraying from the top during the spin stage.

• Leaks Occurring during the Drain Stage: The problem could be a loose or damaged drain hose clamp, leaky/malfunctioning hose, or broken drain pump.
  • Locate the hoses and their connection points by unplugging the washer and carefully moving it away from the wall. 
  • Tighten loose connection points and verify that the hoses are undamaged/not leaking.
  • Swap out any broken/punctured hoses and secure loose drain hose clamps.
  • If a broken drain pump is suspected, contact a licensed technician for replacement.
    
    
• Leaks Stemming from the External Back Hose: Many washing machines have the water hose at the back. To diagnose leaks from this area, run the washer to observe the drain hose and pull it away from the wall for better access.
  • Ensure the drain hose is securely connected and not loose.
  • Inspect the drain hose for any tears, splits, or punctures.
  • If leaking, tighten or replace the drain hose as needed.

Step 3 - Check for Other Potential Issues

Even after inspecting the parts mentioned in step 2, leaks may persist due to other underlying issues. For instance, tub-related issues are potential sources for washers’ leaking from the bottom. This includes cracks or holes that develop in the inner tub itself and worn or failing bearings that support the inner tub. Thoroughly inspecting the tub and its supporting components for any damage is recommended when dealing with a bottom leak.

Other potential culprits include a clogged coin trap or filter restricting water flow, a faulty water inlet valve, or the washing machine’s age. If you’ve exhausted all potential causes and the leak persists, consult a professional plumber for further diagnosis and repair.

Safety Measures & Prevention Tips for a Washer Leaking from the Bottom

Ensuring your washing machine doesn’t leak from the bottom is essential to avoid extensive and expensive water damage. Here are some valuable and easy-to-follow tips to prevent future bottom leaks in washing machines and keep you protected while fixing them:

1. Wear protective gloves when dealing with a washer’s sharp internal parts. 
2. Unplug the washer and any other nearby appliances to prevent electric shocks.
3. Reduce the detergent amount to eliminate residue buildup inside the overflow tube; this can lead to clogs and blockages, which can contribute to leaks.
4. Avoid overloading the washer to minimize vibrations and violent shaking that could pressure the hoses and connections.
5. Keep the washer safe from the wall so as not to compress the back drain hose.
6. Install a washing machine pan to minimize water damage from broken hoses.
7. Always empty pockets before washing clothes to prevent foreign objects from getting through the filter and clogging hoses/pumps. 

Address Washing Machine Leaking to Enjoy Washing Machine Longevity

Fixing the issue early is a best practice when it comes to leaking washing machines. That requires hands-on washing machine maintenance and attention to the washer’s operation and surrounding area. This proactive approach will minimize the risks of severe “collateral damage” and mitigate costly and complex repairs when issues amplify. 

One area prone to leaks and worth inspecting regularly is the washing machine’s supply hose. Neglecting these areas could lead to unexpected bursts, resulting in significant water damage.
