Water damage can sneak up on homeowners, and the everyday appliances we rely on are often the cause. Dishwashers, washing machines, refrigerators, and water heaters can all cause serious damage when leaks go unnoticed. Here’s a closer look at the most common culprits.

1. Washing Machines

Washing machines are notorious for water damage due to hose failures or overflows. Hoses can crack or wear out over time, leading to leaks or floods. Overloading the machine can cause it to overflow, resulting in water damage to nearby flooring or walls.

2. Dishwashers

Dishwashers can cause serious damage if their seals, water lines, or gaskets fail over time. As these mechanisms wear out, slow leaks may go unnoticed until major damage or mold growth has occurred. Addressing small issues before they escalate can help avoid costly repairs and protect your home from water-related problems.

3. Refrigerators

Refrigerators with ice makers or water dispensers contain small water lines that can crack or become loose over time. These leaks often occur behind or underneath the fridge, making them harder to detect until damage to the kitchen floor or walls becomes evident. Regularly checking the water lines can help avoid surprise damage to kitchen floors or cabinets.

4. Water Heaters

A failing water heater can cause extensive water damage. Over time, corrosion and sediment buildup can lead to leaks or bursts, causing water to flood the area around the heater. Replace aging water heaters before they become a hazard, and regularly inspect them for signs of wear or leaks.

5. HVAC Units

Heating and cooling systems can cause water damage through condensation. If the condensate line becomes clogged or the drain pan overflows, water can leak into walls, ceilings, or floors, leading to mold or structural issues. Regular maintenance, like clearing the condensate drain, can prevent these issues.

6. Sump Pumps

When they malfunction, sump pumps can cause water damage, especially during heavy rains or flooding. Water can quickly flood the basement or crawl space if the pump fails, leading to severe damage. Routine maintenance and testing of the sump pump can help prevent this.

7. Garbage Disposals

A garbage disposal leak can cause damage beneath the sink. Loose fittings, gaskets, or worn-out seals often cause leaks, which can go undetected until significant damage occurs. Regularly checking for leaks under the sink can help avoid potential water damage.

8. Toilets

Leaky toilets, especially those with old or worn-out parts, can also cause water damage. Slow, undetected leaks can rot the flooring or lead to mold growth. Regularly checking the toilet’s water connections and replacing any faulty parts can help prevent leaks.


Simple maintenance, like inspecting hoses, seals, and drains, can help avoid expensive repairs. It’s important to check them regularly for leaks to prevent water damage from home appliances.
