Learn What to Do with the E1 Error on Samsung Dishwasher
The E1 fault code signals a leak. When there is a leak in the system, the motor works at a higher RPM.
Check hose connections
This error is assigned to indicate low or zero back pressure in the system when the drain pump is running. Most likely, there is a leak in the drain system. If you see the error on the display, check the system’s hoses and connections. Check the dishwasher’s bottom for water. If there is nothing wrong, make sure the drain hose is positioned at an appropriate height and looped properly. If these are all right, but the error persists, the drain pump is bad.
Run the drain hose lower than the sink drain to ensure sufficient syphoning from the dishwasher.
