Standing water that survives a clean filter, a clear drain hose, and a working disposal connection usually means a failed drain pump or check valve, and replacing those is a job for a technician. FixitBay LLC fixes dishwashers throughout San Francisco, the Peninsula and Marin, licensed in California by the Bureau of Household Goods and Services (BHGS #51001). The diagnostic is $80 and credits toward the repair, you approve a written estimate first, and the work carries a 180-day warranty on parts and labor. Book online for same-day or next-day service.
The most common cause is a clogged filter-the cylindrical filter at the bottom of the tub traps food particles and should be cleaned monthly. If the filter is clean, check the drain hose for kinks or clogs, then verify your garbage disposal connection. In our experience, 80% of drainage problems are fixed by cleaning the filter or clearing a blocked drain hose-both easy DIY repairs under 10 minutes.
During the drain cycle (typically near the end of the wash cycle), listen for a humming or whirring sound-that’s the pump working. Silence during the drain cycle often means the pump isn’t running. A loud grinding or buzzing sound suggests the pump is running but obstructed. If the pump sounds fine but water still won’t drain, the pump may have an electrical failure and needs professional diagnosis.
If your dishwasher was just installed and has never drained properly, the garbage disposal knockout plug is almost certainly the issue. When a dishwasher drains into a garbage disposal, the installer must remove a small plastic plug from the disposal’s inlet port. If it’s still in place, water has nowhere to go.
We recommend fixing the drainage issue before running more cycles. Standing water can become a breeding ground for bacteria and mold. More importantly, if the drain pump is running against a stubborn clog, continued use can burn out the motor-turning an easy $80 repair into a $200+ pump replacement.
If the fix is cleaning the filter or clearing a hose kink, it’s a free DIY repair. If the issue requires professional service-like replacing a drain pump, check valve, or control board-FixitBay LLC charges a $80 diagnostic fee applied toward the repair cost. Most drain pump replacements run from $250 total, parts and labor included, with a 180-day warranty.
