Check if the drain hose is kinked or blocked. Ensure that the sink drain is not clogged. Also, inspect and clean the dishwasher filter and pump area.
To clean the filter, remove the bottom dish rack, twist the filter counterclockwise and lift it out. Rinse it under running water and remove any debris before placing it back.
The 'E4' error code indicates an overflow issue. Check for water leaks and ensure the dishwasher is level. Inspect the water inlet valve and float switch if needed.
Ensure that you use a rinse aid, select a higher drying setting if available, and avoid overcrowding the dishwasher to allow better airflow.
Ensure that dishes are loaded correctly and not touching each other. Check for any foreign objects in the spray arms or filter area. Tighten any loose components.
It's recommended to clean the spray arms every 1-2 months. Remove them and rinse under running water. Use a toothpick to clear any blocked holes.
Check if the door latch is obstructed or damaged. Ensure that the racks are not overloaded and that nothing is protruding from the racks blocking the door.
Use a high-quality automatic dishwasher detergent, preferably in tablet or powder form, to ensure optimal cleaning performance. Avoid using too much detergent.
Clean the filter regularly, use a dishwasher cleaner monthly, and ensure that food debris is cleared from dishes before loading. Leave the door slightly ajar to improve air circulation.
