Washer shows E31; often related to water level sensor signal out of range.

Safety first: Unplug the washer before working near the control area.

• Inspect pressure hose: Remove the top panel of the Insignia washer and locate the pressure sensor and hose. Check for kinks, blockages, or disconnections.
• Clean air dome: If accessible, remove the hose at the tub and clear any soap scum or debris from the air dome port.
• Dry connectors: Ensure the sensor's electrical connector is dry and firmly seated.
• Replace sensor: If E31 persists, replace the Insignia pressure sensor with an OEM part and retest.
• Control board consideration: If a new sensor does not resolve the error, the main control board may be misreading the signal and should be evaluated by a technician.
