Why Is My Chatsworth Dishwasher Leaking?
Common Causes and What You Can Do About It
Dishwasher Leaks Are More Than Just a Nuisance
A leaking dishwasher can lead to water damage, mold, and even electrical hazards if ignored. If you’ve discovered a puddle forming beneath or around your dishwasher in your Chatsworth home, don’t panic—but do act quickly. Leaks can stem from a number of common issues, some of which are easy to spot while others require professional attention.

Most Common Causes of Dishwasher Leaks
Worn Door Gasket
The rubber seal around the dishwasher door—called the gasket—can become brittle, warped, or cracked over time. If it doesn’t form a tight seal, water will leak out during the wash cycle.
Faulty or Loose Water Inlet Valve
This valve controls water flow into your dishwasher. If the valve is cracked, loose, or has a faulty connection, it may leak at the base of the unit. This is especially common in older models.
Clogged or Damaged Drain Hose
A dishwasher must expel dirty water at the end of each cycle. If the drain hose is cracked, clogged, or disconnected, water may back up or leak out onto your floor.
Overloading the Dishwasher
Too many dishes or poor loading can cause water to spray in unintended directions, which may lead to water escaping past the door gasket or pooling near the base.
Using the Wrong Detergent
Using dish soap or non-dishwasher detergent can create excessive suds, which may push water out of the unit. Always use a detergent designed for your dishwasher.
Faulty Float Switch
This small device monitors water levels. If it’s stuck or malfunctioning, your dishwasher may overfill and leak as a result.
Cracked Tub or Spray Arm
Less common but possible: a crack in the dishwasher tub or damage to the spray arms can cause misdirected water and leaks. These issues usually require part replacement.
