What does E1 error mean on Insignia NS-DWR3SS1 Dishwasher?
- MMichael WhiteSep 8, 2025
The E1 error code on your Insignia dishwasher indicates either insufficient water flow or excessively high water pressure from the incoming line. Make sure that the water supply to the dishwasher is turned on. Ensure the water pressure is within the range of 20~80 psi. Check the drain hose for any obstructions. If issues persist, contact Customer Service.
