Do’s and Don’ts for Peak Dishmachine Performance

Every piece of equipment in the foodservice kitchen needs to be properly used and maintained. Improper use and poor maintenance can slow an operation down, and even lead to downtime, with major disruptions to daily business.

From the before-opening prep work until the last diner’s silverware is washed, the dish machine is working throughout the day. So it’s imperative that proper maintenance and cleaning procedures be performed to keep the dish machine at peak performance.

Here are some “do’s and don’ts” for the care and operation of your commercial dishwasher to keep it delivering peak performance:

  • Prescrap dishes thoroughly, removing any large particles of debris. 
  • Place the ware in a plastic dishrack and be sure to leave adequate spacing between items so water and chemicals can reach all parts of the ware.
  • At the end of each operating day, clean the machine thoroughly. Check, empty, rinse, and replace the machine’s scrap basket, rinse it and leave the machine door open to dry. Make sure that the wash arms and nozzles are clean.
  • Ensure your water is at the proper level of hardness (3 grains per gallon is recommended).
  • Use only commercial dishwashing chemicals recommended by your chemical provider. Do not use detergent made for home dishwasher use. And remember to use gloves and eye protection when handling chemicals. 
  • Deliming the machine is critically important. Follow the deliming schedule recommended by the manufacturer. 
  • Never exceed the recommended concentration of detergent, sanitizing solution, rinse additive or lime scale remover. Overusage of any of these products can be harmful to long-term machine performance.
  • For machine cleaning, use only products that are formulated to be safe for stainless steel. Never use steel wool to clean warewasher surfaces.

It’s also important to have staff trained on proper machine operation. While many commercial dishwashers are easy and intuitive to operate, a well-trained operator can help spot little problems before they become big ones. Training videos and wall charts provided by the manufacturer can be helpful staff aids.
