How to Fix Error E2

- Ensure the household water supply valve to the dishwasher is fully open.
- Inspect the water inlet hose for kinks, damage, or blockages at both ends.
- Clean the inlet filter screen located at the connection of the water supply hose.
Technician Only Inspect and service water level/pressure sensor and inlet valve
- Disconnect power and remove access panels to locate the pressure sensor hose and pressure chamber.
- Check for blockages in the pressure hose and clean or replace if necessary.
- Test the water inlet valve for proper operation and continuity; replace if faulty.
- Use diagnostic tools to verify proper water level sensor readings during a cycle.
Parts needed: water inlet valve, pressure sensor/level sensor, pressure chamber/hose
