Dishwasher leaks are easy to miss because much of the plumbing is hidden under the appliance or inside the cabinet. By the time water appears on the kitchen floor, it may already have traveled under cabinets or flooring.
Common dishwasher leak sources
- Loose or damaged supply lines
- Drain hose failures
- Door seal leaks
- Clogged or overflowing drains
- Connections under the sink
Check under nearby cabinets
Water often moves through the toe-kick area and can soak cabinet bases. Swelling, discoloration, peeling finishes, or a musty smell can indicate hidden moisture.
Flooring can trap water
Floating laminate, engineered flooring, and other layered systems can hold water underneath the visible surface. The flooring may not show obvious damage immediately.
Walls beside the appliance may also be wet
Leaks can reach drywall behind the dishwasher or the sink cabinet. Moisture readings help determine whether wall cavities need drying.
Dry before rebuilding
Cabinet and flooring repairs should wait until the affected structure is dry. Otherwise, moisture can remain trapped behind new finishes.
