Hobart dishwasher shows inconsistent wash results; some racks are clean while others are still soiled.

Safety first: Turn off power before removing wash arms.

• Clean wash arms thoroughly: Remove and clean all wash arms, ensuring every jet is open and free of debris or scale.
• Standardize loading: Train staff to load racks according to Hobart guidelines, avoiding stacking items or blocking spray from reaching all surfaces.
• Check wash pressure: If equipped with a pressure gauge, verify wash pressure is within specification. Low pressure suggests pump wear or intake restriction.
• Separate heavy soil loads: Run heavily soiled items separately from lightly soiled wares to prevent redepositing soil.
• Service pump if needed: If wash pressure remains low after cleaning, the wash pump impeller or motor may need replacement.
