Dishwasher causing backup in sink: diagnosis and repair

Kitchen4 min readDecember 2024

Dishwasher and sink connection issues

When your dishwasher causes water to back up into your kitchen sink, it indicates a problem with the shared drainage system that requires professional attention.

Why this happens

  • Shared drain line: Dishwashers and sinks often share the same drain
  • Garbage disposal issues: Clogs in the disposal can affect both appliances
  • Improper installation: Incorrect dishwasher drain hose positioning
  • Blockage downstream: Clogs further down the line affect both fixtures
