You find a puddle in front of the dishwasher, or water under the kitchen sink. A dishwasher leaking water can damage your floor and cabinets before you notice it. The good news is that many leaks have simple causes.
This guide shows where dishwasher leaks usually come from, what you can check safely, and when to call a pro. For fast help in New Braunfels, call New Braunfels Appliance Fix at (830) 240-5230.
Why is my dishwasher leaking?
The most common causes are a worn or dirty door gasket, the wrong detergent, a dishwasher that is not level, a loose or cracked hose, a leaking water inlet valve, or a worn pump seal. Where the water shows up is the best clue. Water at the front of the door usually points to the gasket or suds. Water under the unit usually points to hoses, valves, or seals.
Safety first
Turn off the dishwasher and shut off power at the breaker before you remove the kick plate or touch any wiring. Close the hot water valve under the sink if water is still coming out. Dry the floor so no one slips.
Common causes and fixes
1. Worn or dirty door gasket
The rubber gasket around the door seals in the water. Food bits and grease can keep it from sealing, and old gaskets can crack or flatten. Wipe it with warm, soapy water. If it is torn or hard, it needs to be replaced.
2. Wrong detergent or too much of it
Regular hand dish soap makes thick suds that can push water out past the door. Even dishwasher detergent can cause suds if you use too much. Use only dishwasher detergent, in the amount the label says.
3. Dishwasher not level
If the dishwasher tilts forward, water can pool at the door and leak out. Check with a small level and adjust the front feet.
4. Loose or cracked supply line
The water line runs from the valve under the sink to the dishwasher. A loose fitting or cracked line leaks every time the dishwasher fills, and sometimes all the time.
5. Leaking water inlet valve
The inlet valve lets water into the dishwasher. When it wears out, it can drip from behind the kick plate. This part needs a technician to replace.
6. Worn pump seal or drain hose
The pump and its seals sit under the tub. A worn seal or a loose drain hose can leak during the wash or drain. You may see water only during certain parts of the cycle.

How to prevent dishwasher leaks
- Use only dishwasher detergent, in the right amount.
- Wipe the door gasket every few weeks.
- Clean the filter monthly. New Braunfels has hard water, and buildup can block parts.
- Check under the sink every few months for drips.
- Do not overload the racks so the door closes fully.
If your dishwasher leaves water in the bottom, read dishwasher not draining. For spots and film, see dishwasher not cleaning in hard water.

Frequently Asked Questions
Why is my dishwasher leaking from the bottom of the door?
The most common causes are a worn or dirty door gasket, a door that does not close evenly, too much detergent, or regular dish soap used by mistake. Check and clean the gasket first.
Why is there water under my dishwasher?
Water under the unit often comes from a loose or cracked supply line, a leaking water inlet valve, a worn pump seal, or a drain hose that has come loose. These are hidden behind the kick plate.
Can I use my dishwasher if it is leaking?
It is best not to. Even a small leak can soak the subfloor and cabinets over time. Turn the dishwasher off until you find the cause.
Can regular dish soap make a dishwasher leak?
Yes. Hand dish soap makes a lot of suds, which can push water out past the door seal. Only use detergent made for dishwashers.
