Kitchen Disaster Series, Vol. 1: Dishwasher Leaks
A slow drip under the sink or a mysterious puddle in front of your dishwasher might not seem like a big deal—until your wood floor starts to buckle or mold forms behind your cabinets.
Dishwasher leaks are one of the most common causes of kitchen water damage in the Chicagoland metropolitan area. Whether you’re in a Wilmette bungalow or a Logan Square condo, the combination of hot water and soap can cause extensive damage to hardwood floors, drywall, cabinetry, and insulation. Do you know what to do for a Dishwasher leak in the Chicagoland metropolitan area?
Common Causes of Dishwasher Leaks
Your dishwasher is more complex than it looks. Leaks can stem from multiple places:
-
Cracked or loose water supply line
-
Faulty door gasket or latch
-
Improper leveling causing water to pool and overflow
-
Broken float switch or drainage failure
-
Clogged or damaged drain hose
-
Excessive detergent causing suds to spill out
Even a pinhole leak can release gallons of water over time, especially if your dishwasher runs daily.
Signs of Hidden Water Damage in Your Kitchen

Dishwasher leaks don’t always gush. Often, they cause slow, persistent water damage that spreads under the surface. Watch for:
-
Warping or cupping of wood or laminate flooring
-
Discoloration or peeling of baseboards or cabinetry
-
A musty smell near your dishwasher
-
Visible mold or mildew
-
Water stains on the ceiling below (in multi-story homes)
-
Soft or sagging drywall around or behind the dishwasher
Why Wood Floors and Hot Water Don’t Mix

Hot water from dishwasher leaks doesn’t just sit—it seeps into wood grain, causing it to expand, warp, and split. Add in soap and grease, and you’ve got the perfect recipe for rot, mold, and subfloor delamination.
We’ve seen Chicagoland kitchens where:
-
Hardwood had to be completely removed and replaced
-
Subfloors were soaked and grew mold within 72 hours
-
Cabinet toe kicks hid months of slow leaks
What to Do Immediately After a Dishwasher Leak
-
Turn off the dishwasher and water supply
-
Soak up standing water with towels or a wet vac
-
Remove the bottom kick plate and inspect for moisture or mold
-
Call a certified restoration team (like ServiceMaster By Simons) to assess hidden damage with moisture meters and thermal imaging
💡 Pro Tip: Insurance may not cover long-term leaks. Catching it early matters.

Frequently Asked Questions About Dishwasher Leaks
Q: How do I know if my dishwasher is leaking?
A: Look for puddles near the base, warped floors, or a musty smell. Hidden leaks often damage wood floors and cabinets before you notice.
Q: Is dishwasher leak damage covered by homeowners insurance?
A: Often yes—if the leak is sudden and accidental. Long-term or neglected leaks may be denied. It’s best to act fast and document the damage.
Q: Can I dry out my kitchen myself?
A: Small spills, yes. But dishwasher leaks often soak subfloors and insulation. Professional drying prevents mold and structural issues.
Q: How fast does mold grow after a leak?
A: Mold can begin forming within 24–48 hours, especially in dark, damp areas like under dishwashers and behind cabinetry.
