Washing Machine Overflows – Causes and Clean-Up

Nasutsa Mabwa
June 23, 2025A washing machine overflow can lead to serious water damage if not addressed quickly. Learn the common causes, prevention tips, and how ServiceMaster Restoration By Simons helps Chicago homeowners clean up safely and effectively.
What Causes Washing Machine Overflows?
A washing machine overflow can quickly turn from a minor inconvenience to a major water damage emergency. Understanding the most common causes can help you prevent a costly disaster in your Chicago-area home.
Malfunctioning Water Inlet Valve
The water inlet valve controls the flow of hot and cold water into your washing machine. If it fails to shut off after the wash tub fills, water will continue to pour in and overflow. To test this, turn off the machine’s power during filling. If water keeps flowing, the valve is likely the problem and needs replacement.
Broken Pressure Switch
This switch signals the machine to stop water flow once the desired level is reached. A faulty pressure switch means nothing stops water from filling the machine, leading to overflow.
Low Water Pressure
Water pressure below 20 PSI can prevent the inlet valve from receiving the signal to stop water flow. This can cause the washer to overfill.
How to Prevent Washing Machine Overflows
- Avoid overloading the machine; distribute laundry evenly and loosely.
- Replace old rubber supply hoses with durable stainless steel braided hoses.
- Install a water alarm or detector near your washer to alert you to leaks.
- Consider installing an automatic shutoff valve to stop flooding from failed hoses or valves.
- Use the correct detergent for your machine, and never use more than recommended to avoid excess suds.

What to Do If Your Washing Machine Overflows
If you face a washing machine overflow:
1. Turn off electrical power at the circuit breaker.
Do not press "Cancel" on the washer, as this could activate the drain cycle and worsen flooding.
2. Mop up water and remove wet rugs or furnishings.
Dry these items immediately to prevent further damage. Water from a washing machine is generally clean, so many items can be salvaged.
3. Remove wet clothes from the machine.
Wring them out over a sink or outside to minimize additional water inside the appliance.
4. Inspect water supply hoses.
Move the washer and check for leaks or drips. Replace damaged hoses promptly.
If water has spread beyond the laundry area or seeped into hidden spaces, it’s best to call professionals. Water can cause damage behind walls or under floors and promote mold growth if not properly dried.
