You’re loading up the dishwasher after dinner, you press start, walk away — and then you spot it: a small puddle forming on your kitchen floor. That sinking feeling sets in.
A leaking dishwasher doesn’t just leave a mess — it can damage your cabinets, flooring, and even cause mold if not handled quickly. But the good news? Not every leak means you need a new appliance. In many cases, the issue is minor and completely repairable.
As a trusted appliance repair service in Des Plaines and nearby areas, we’ve seen all kinds of dishwasher leaks. Here’s what might be going on — and when to call in the pros.
🧼 1. Worn-Out Door Gasket
The door gasket is the rubber seal that runs around the inside of your dishwasher door. Over time, it can wear out, crack, or come loose — allowing water to seep out during a wash cycle.
What to look for:
- Water dripping from the bottom or corners of the door
- Visible cracks or looseness in the gasket
- Mold or grime buildup along the seal
Quick Fix: Clean the gasket with warm soapy water. If it’s cracked or hardened, it’s time to replace it — a simple job for most repair techs.
💧 2. Leaky Water Inlet Valve
This valve controls how much water enters your dishwasher. If it’s faulty or clogged, it can allow too much water in — or leak around the valve connections.
What to look for:
- Water pooling under the dishwasher
- Water leaking even when the unit is off
- Rust or mineral buildup near the valve under your sink
Why it matters: A damaged inlet valve wastes water and can strain your appliance’s motor.
🌀 3. Damaged or Misaligned Spray Arm
The spray arm spins and sprays water during the wash cycle. If it’s cracked, clogged, or not spinning correctly, water pressure may be redirected toward the door — causing leaks.
What to do:
- Remove the arm and rinse it under hot water
- Check for debris, cracks, or uneven spinning
- If damaged, replace it (they’re inexpensive parts)
🧰 4. Dishwasher Not Level
Believe it or not, an unlevel dishwasher can cause water to pool and overflow near the door. Even a small tilt can lead to leakage.
How to check:
- Place a level across the front edge
- Adjust the legs under your dishwasher until it’s perfectly level
🛠️ 5. Loose or Cracked Drain Hose
Drain hoses carry used water out of the dishwasher. If they become loose or cracked — especially behind or under the unit — water can leak during draining.
Signs of this issue:
- Leaks at the back of the dishwasher
- A musty or sewage smell under your sink
- Wet spots in the cabinet where the hose connects
Don’t wait too long on this one — a leaky hose can cause long-term water damage.
⚠️ Should You Try to Fix It Yourself?
Some issues, like cleaning the spray arm or checking for a clogged gasket, are safe for a DIY attempt. But if you’re dealing with electrical parts, water valves, or anything involving disassembly — it’s best to leave it to the pros.
Trying to force a repair without the right tools or experience could make things worse — and more expensive.
