Washer displays E9 and may stop filling or draining; sometimes associated with water level anomalies.

Safety first: Unplug the washer and turn off water supply immediately if overfilling occurs. Mop up any spilled water to prevent slipping.

• Shut off water: Close both hot and cold supply valves to the Insignia washer to stop filling.
• Check tub water level: If the tub is overfull, manually drain using the drain filter or a wet/dry vacuum before proceeding.
• Inspect inlet valves: With power disconnected and water turned off, remove the hoses and check if water continues to drip through the valve. A valve that leaks when de-energized is defective.
• Examine pressure hose and sensor: Remove the top panel and inspect the pressure hose for disconnection or cracks. Reseat it on the tub air dome and sensor, and secure with clamps.
• Test fill after reset: Restore water and power, then run a small test cycle. If the washer continues to overfill or E9 returns, replace the Insignia water inlet valve and/or water level sensor as indicated by testing.
• Control board evaluation: Persistent overflow with good valves and sensor suggests a control board fault; contact a professional.
