Possible Causes

Rinse aid not dispensing, Final rinse temperature too low, Excessive rinse water left on wares due to low pressure, Improper rack loading preventing drainage

How to Fix / Troubleshooting

Safety first: Allow the machine and wares to cool before inspection.

  • Check rinse aid level: Ensure the rinse aid container is filled and the pickup tube is submerged. Prime the rinse aid pump if necessary.
  • Verify rinse temperature: Observe the final rinse temperature on the display or gauge. It should meet Hobart specifications for your model. If low, troubleshoot the booster heater and supply temperature.
  • Inspect rinse nozzles: Clean final rinse nozzles to ensure even coverage and proper sheeting of water off the wares.
  • Improve rack loading: Load dishes at an angle to promote drainage and avoid nesting items that trap water.
  • Adjust chemical dosing: Work with your chemical supplier to optimize rinse aid dosage for your water hardness and ware type.
