Why Is My Dishwasher Leaking? 8 Things to Check
A dishwasher leak can come from the door seal, filter area, drain connection, detergent use, or a plumbing connection underneath.
What to check
Start by identifying the problem
Stop the dishwasher and switch off power at the accessible control or breaker if needed and safe. Mop up standing water.
Check the easiest causes first
Check the door gasket for food debris, damage, or poor seating. Clean it gently according to the manufacturer's instructions.
Inspect the relevant components
Make sure the dishwasher is not overloaded in a way that prevents the door from closing properly.
Look for signs of a larger problem
Use the detergent type and amount recommended for your dishwasher. Hand dish soap can create excessive suds and cause problems.
Avoid risky shortcuts
Inspect the visible drain hose connection under the sink if accessible. Do not disturb electrical wiring.
Compare the pattern
Check whether the leak occurs during filling, washing, draining, or throughout the cycle. Timing can help identify the source.
Consider when the problem started
Call a qualified appliance technician or plumber if water leaks from underneath the machine, a connection is damaged, or the leak persists.
When to call a professional
Get professional help when the problem persists after basic checks, involves a component you are not qualified to service, creates a safety hazard, causes active water damage, or affects multiple systems or fixtures. Prompt service can help prevent a small problem from becoming more expensive.
Quick checklist

- Look for leaks, damage, unusual odors, or warning signs.
- Follow the manufacturer's instructions for any homeowner maintenance.
- Do not bypass safety devices or work on hazardous components.
- Get professional help when the cause is unclear or the problem returns.
