Fault Code	Cause	Solutions
E1	Water Inlet Fault Issues with water supply, inlet valve, or hose	Confirm the water tap is fully turned on and pressure is sufficient Inspect the inlet hose for any twists, bends, or obstructions Detach and rinse the inlet filter to clear debris Examine the inlet valve for faults and replace if needed
E2	Drainage Fault Blocked drain hose, dirty filters, or faulty pump	Thoroughly rinse the dishwasher filters Inspect the drain hose for blockages or sharp bends Check for unusual pump sounds and replace if necessary
E3	Heating Fault Malfunctioning heating element or thermostat	Use a multimeter to verify the heating element’s condition Assess the thermostat and swap if defective If components are functional, consider replacing the control board
E4	Overflow/Leakage Fault Overflow, faulty inlet valve, or leaks	Inspect door seals and the base for potential leaks Test the water level sensor and replace if it’s malfunctioning Ensure the inlet valve shuts off correctly when needed
E5	Motor Fault Problems with the wash motor	Examine motor connections for secure wiring Run diagnostics to check motor efficiency Replace the control board if motor issues persist

E9	Water Softener Fault Issues within the softener unit	Verify salt levels and refill as needed Replace the softener valve if it’s not functioning correctly
EA	Communication Error Faulty communication between control boards	Power cycle the dishwasher to attempt a reset Inspect wiring for loose or damaged connections Replace control module if issues remain unresolved
EC	Heating System Fault Defective heating system parts	Swap out any faulty heating elements Test thermostat performance and replace if needed Consider replacing the control board for persistent issues
