Dishes are not coming clean; food soil remains on plates and glasses after a full cycle with a Hobart dishwasher.

Safety first: Turn off power and allow the machine to cool before disassembling wash arms.

• Clean wash arms: Remove upper and lower wash arms. Use a small brush or toothpick to clear each jet nozzle of food particles and scale. Rinse thoroughly.
• Clean filters and screens: Remove tank strainers, scrap screens, and pump intake filters. Wash them under running water to remove grease and debris.
• Check detergent: Verify you are using the correct Hobart-approved commercial detergent and that the dosing pump is set to the supplier’s recommended concentration.
• Inspect wash pump performance: During operation, observe spray intensity. Weak or uneven spray may indicate a worn wash pump impeller or partially blocked intake, requiring pump service or replacement.
• Regular maintenance: Implement a daily cleaning routine for arms and filters to maintain consistent wash performance.
