Dishwasher leaking water — San Francisco, California
A leaking dishwasher can damage kitchen flooring, cabinets, and the subfloor beneath them before you notice the problem. Water may pool under the unit, seep forward onto the floor during cycles, or drip from the door seal. Common causes include a worn or cracked door gasket, a loose or damaged supply line connection, a faulty inlet valve, a cracked pump housing, or a clogged drain hose that forces water backward. If the dishwasher is older than 8–10 years and the tub or pump is cracked, replacement is usually more cost-effective than repair. A licensed plumber can diagnose the source, tighten or replace supply and drain connections ($100–$250), replace a door gasket ($50–$150 parts + labor), swap a faulty inlet valve ($150–$300), or advise on replacement. Act fast — even a small dishwasher leak left for weeks can warp the subfloor and encourage mold growth in the enclosed cabinet space.
Why this is common in San Francisco
San Francisco's Victorian and Edwardian housing stock hides original galvanized and cast-iron pipes long past their service life, prone to corrosion and low pressure. Hilly terrain complicates drainage, and seismic shifting periodically cracks pipe joints and sewer laterals.
