Dishwasher fills with water but does not wash; you hear filling and maybe a hum, but spray arms do not move and dishes stay dirty.

Safety first: Disconnect power and be cautious of sharp edges and broken glass inside the sump.

• 1. Verify water level: After fill, open the door and confirm water level is just below the door opening. If low, address inlet issues first.
• 2. Clean filters and sump: Remove lower rack and filters. Inspect the sump for debris blocking the intake to the circulation pump. Remove any obstructions.
• 3. Check spray arms: Ensure spray arms spin freely by hand and are not blocked by dishes. Remove and clean them if clogged.
• 4. Listen to motor: Start a wash cycle and listen. A loud hum without water movement suggests a seized pump. Access the circulation pump under the unit and inspect the impeller for obstructions.
• 5. Replace circulation pump: If the motor is seized or open-circuit, install a new Insignia-compatible circulation pump assembly.

If you are unsure about working under the dishwasher, seek professional service.
