1. Turn the dishwasher off and start a new cycle to clear the error.
2. Use only detergent made for automatic dishwashers, never hand dishwashing liquid.
3. To clear detergent residue from the tub, put 4–8 oz (100–200 ml) of milk in a shallow bowl on the upper rack and run the Auto cycle.

1. Check that the dishwasher is level: with the lower rack out, place a level on the inside wall of the tub, and check that the gap between tub walls and door liner is equal on both sides.
Qualified technician If it is not level, have the installer adjust the leveling feet.
