Dishwasher leaves greasy or cloudy residue on dishes and inside the tub.

Safety first: Let the appliance cool before cleaning.

• Clean filters and sump: Remove all filters and clean thoroughly. Remove any grease deposits from the sump and door edges.
• Run hot program: Periodically run the hottest available program with a dishwasher cleaner to dissolve grease.
• Increase detergent: If you have very greasy loads, slightly increase detergent dosage within manufacturer recommendations.
• Avoid overloading: Ensure water can reach all surfaces; do not stack dishes too tightly.

If water is not heating properly, a heating fault may be present and should be diagnosed.
