DIAGNOSIS E24 indicates a water intake fault. The dishwasher did not fill with the required amount of water within the expected time.
FIX Check your water supply. Ensure the sink's hot water valve under the sink is fully open. Inspect the inlet hose for kinks. Disconnect the fill hose from the valve and check the mesh filter for debris; clean it if clogged. Restart the dishwasher.
IF THAT DIDN'T WORK The water inlet valve solenoid may be faulty. Test the valve for continuity with a multimeter. A failed valve will not open to allow water in.
