The short answer
Check the Obvious First
Start by pulling the dishwasher out slightly, if you can, and look underneath with a flashlight. A small puddle or damp spot often points to a loose connection rather than a cracked tub. Wipe the area dry, then run a short cycle and watch where moisture appears.
Also inspect the door seal for food debris or cracks. A worn gasket lets water escape during the wash, and it can run down the front and pool at the base. If the seal looks damaged, replacing it is a simple fix you can often do yourself.
- Check the door gasket for tears or buildup
- Tighten the supply line nut at the shutoff valve
- Look for cracks in the drain hose
- Ensure the dishwasher is level so water doesn't run to one side
- Clean the filter to prevent overflow and backpressure
Look at the Hoses and Connections
The water supply line and drain hose are common leak points. If the compression nut is loose or the hose has a pinhole, water can drip down the side and appear as a bottom leak. Turn off the water at the shutoff valve, then gently tighten connections with a wrench.
Drain hoses can also leak where they connect to the sink drain or garbage disposal. If the clamp is loose, water backs up and seeps out. Inspect the hose for kinks or cracks, and replace it if you see any damage.
When the Tub or Pan Is the Problem
If no hose or gasket issue shows up, the leak may come from a cracked tub or a damaged internal water pan. A crack in the plastic tub can let water escape during a cycle. You might notice water only when the dishwasher is running, not when it sits idle.
A rusted or split water pan under the unit also leaks. This part catches overflow from the tub, and if it develops a hole, water drips onto the floor. Replacing a tub or pan is more involved and often worth doing with a pro, especially if the unit is older.
Why Acting Fast Matters
Even a small leak can soak nearby cabinets, baseboards, and subflooring. Water that sits for days encourages wood swelling and mold growth. In a semi-arid climate with cold snowy winters and hot dry summers, indoor moisture can still cause damage quickly.
If you notice a musty smell, warped cabinet panels, or soft flooring near the dishwasher, the leak may have spread beyond the appliance. Catching it early keeps the repair smaller and protects your home's structure.
When to Call the Pros
If you cannot find the source, or if water has spread under the cabinets, local water damage pros can help. They use moisture meters and thermal imaging to trace hidden water without tearing things apart. This is especially useful when the leak has traveled along joists or into walls.
The pros can also dry out affected areas and check for mold before it becomes a bigger problem. If you live in Orem, keep your shutoff valve location written down so you can stop the water quickly during an emergency. Policies vary, and your insurer decides what is covered.

Why is there water under my dishwasher after every cycle?
A recurring puddle often means a loose connection, a worn gasket, or a cracked tub. Run a cycle with the lower panel off to watch for drips. If the leak only happens during the wash, the tub or pan is likely the culprit.
Can I fix a dishwasher bottom leak myself?
Yes, for simple issues like a loose hose clamp or a dirty gasket. Tighten connections and clean the seal first. If the leak continues, the problem may be internal, and a pro can diagnose it without guessing.
How do I know if the leak damaged my floor?
Look for warped laminate, stained wood, or a soft spot when you press down. A musty odor near the baseboard also hints at trapped moisture. A moisture meter can confirm hidden wetness in the subfloor.
