Washing machines are one of the most common sources of water damage in the home, and the damage can be costly. After paying the deductible, the national average claim for water damage caused by washing machines is over $5,000.
Since each washing machine has multiple ways of causing water damage, many homeowners do not fully understand the risks, prevention options, or cleanup options. Knowing just a little about how your washing machine can cause water damage can help you save thousands of dollars and a lot of headaches.
Supply Hose Leaks Cause Most Washing Machine Water Damage
More than 50% of all washing machine water damage claims can be traced back to a supply hose failure. This can be caused by:
- Pinching the hose while installing or replacing a washing machine, causing a hairline break
- A poor connection to either the washing machine or wall
- The hose’s own aging, which can lead to brittleness
Washing machine intake hoses are high-flow lines and can output over 600 gallons of water in an hour.
If your washing machine’s supply hose is more than 5 years old or isn’t steel braided, replace them as soon as possible. It may sound a little excessive until you realize that a new pair of hoses can cost under $30 and can easily be installed without a plumber.

The good news is that intake line water damage is category 1, which means it contains relatively few biological contaminants.
Washing Machine Drainage Issues Can Cause Flooding
If your sewer backs up, if there’s a clog in the drainage pipe, or if your drain pipe simply isn’t lined up right, your washing machine’s drainage system is going to cause at least some water damage.
The most crucial issue is to avoid a sewer line clog. If your sewer backs up, you could be faced with category 3 water damage, which is filled with contaminants that can pose serious health risks. Be extremely careful when running your washing machine if your home’s sewer line has a history of backing up, or if you’ve recently experienced a storm.
Preventing Water Damage from your Washing Machine
The most effective ways of preventing damage from your washing machine are to:
- Replace the washing machine intake hose every 5 years
- Check your sewer line after a storm, before running your washing machine
- Don’t overload your washing machine
- Have your machine professionally installed to avoid water line pinches and drainage issues
- Shut off the intake valve behind your machine at the first sign of trouble
- If you can’t access the intake valve, know how to shut off your home’s water main
