Appliance leaks rarely look like emergencies. A cracked supply hose or a clogged drain pan lets water out slowly behind a dishwasher or under a washer, and the first sign is a soft spot in the floor or a smell. By then the cabinet bases and subfloor have often been wet for days.
Where appliance water goes
- Under dishwashers, into the cabinet base and subfloor
- Behind washing machines, along the wall and floor edge
- Beneath refrigerators with water dispensers or ice makers
- Below sinks, through the cabinet floor into the room
The water follows the easiest path, which is often under the flooring, so the visible spot rarely shows the real extent. Moisture readings around the appliance and along adjoining walls show where it traveled.
Owners and renters
Single-family houses make up roughly 96 percent of the city's housing units, and most occupied units are lived in by their owners, so most appliance leaks are the homeowner's to report and fix. Where a unit is rented, the tenant usually tells the landlord at once, the landlord handles the structure and the tenant's own policy usually covers belongings. Photos taken before cleanup help either way.
See the water extraction page for removal and the main appliance leak page for the full scope.

Appliance and Supply Line Leaks questions in Walnut, CA
How does a dishwasher leak go unnoticed?
The water runs out the back or underneath, soaks the cabinet base and flows under the flooring. Nothing shows on the surface until the floor softens or swells at an edge.
Should the appliance be replaced right away?
Only after the water is stopped and the damage is assessed. A failed hose or valve may be the only broken part, so repair and cleanup can proceed independently.
Who handles the leak in a rented home?
The tenant reports it to the landlord immediately, and the landlord typically arranges structural drying and repair. A renter's policy usually covers personal belongings, but leases vary.
Can cabinets be saved after an appliance leak?
Solid cabinet bases with finished surfaces can often be dried, while particleboard boxes that swell usually cannot. Moisture readings and a close look at the edges decide.
Does insurance cover a leak that went unnoticed for weeks?
Sudden discharge is often covered, while long term seepage often is not. Photos, dates and moisture logs help show what happened and when.
