The E1 error code on a Kenmore standalone or built-in ice maker indicates the unit failed to detect water entering the reservoir within the expected fill time. The water inlet cycle timed out without the water level sensor confirming a successful fill.
Causes
- Water supply valve turned off or low water pressure
- Kinked or frozen water supply line
- Clogged water inlet filter
- Failed water inlet solenoid valve
- Water level sensor malfunction
What To Do
- Verify the water supply valve (usually under the sink or behind the unit) is fully open.
- Check the supply line for kinks or freezing.
- Replace the water inlet filter if it has not been replaced in over 6 months.
- If water supply is confirmed OK, the inlet solenoid valve requires professional testing.
