Dishwasher Leaking? Here’s What to Check

Noticed a puddle near your dishwasher? You’re not alone. Many common causes of leaks are easy to troubleshoot.

Before calling for help, try these simple steps.

Start with the Basics

Check if the dishwasher is level.
- Uneven placement can lead to water pooling.
Use the right detergent.
- Too many suds from the wrong soap can cause overflow.
Inspect the door.
- Make sure it closes completely and nothing is blocking the seal.
Clean the filter.
- A clogged filter can prevent proper drainage and cause overfilling.

If these checks don’t solve the issue, it’s time to dig deeper.

Step-by-Step Leak Inspection

Door Gasket

Check for cracks, wear, or buildup on the seal.
Remove, clean, or replace the gasket if needed.

Water Inlet Valve

Located under the dishwasher.
If stuck open, it can cause overfilling.
Most faulty valves need to be replaced.

Hoses and Connections

Inspect for cracks or loose fittings.
Tighten or replace as needed.

Pump and Seals

Look for leaks around the pump housing.
Replace worn gaskets.

Float Switch

Prevents overfilling.
Check for obstructions or a stuck float.
Replace if not functioning correctly.

Spray Arms and Tubing

Damaged parts can spray water in the wrong direction.
Replace cracked or broken components.

Motor Shaft Seal

A worn seal can cause leaks from underneath.
Replacement may be necessary.

DIY Tips

Start with the easiest fixes first.
Take photos during disassembly.
Always unplug the dishwasher before repairs.
