CMA Model EST44 Maintenance Checklist

• Always scrape dishes before placing them in the dishwasher. Ideally, you should give them a quick rinse as well. Try to ensure that few food particles remain on the dishes before placing them in the dishwasher.
• Clean it every day. Always follow your machine’s specific cleaning guidelines carefully. Remove food particles and other debris before cleaning the interior of the dishwasher, including the spray nozzles and other parts.
• Check detergent, sanitizer, and rinse aid levels each day. If there is not enough soap, sanitizer, or rinse aid going into the machine during a cycle, dishes will not come out clean. Always ensure you have adequate solution levels before starting a cycle.
• Allow the dishwasher to air dry after cleaning. Do not shut the dishwasher after you have finished using it for the workday. You should allow it to air dry overnight, or else you run the risk of breeding harmful bacteria.
• Ensure the filter is clean. You should change your filter approximately every twenty cycles, or more often if your machine is used more frequently than usual. If there are pieces of food or other debris stuck in the filter, place the filter under running water and clean with a soft brush. Reinstall the filter afterward.
• Refill the tank every 20 cycles. When you change the filter, you should replace the water in the tank to ensure dishes come out clean every time. Cleaning the interior tank with a manufacturer’s approved cleaning solution can also help reduce bacteria for a deeper clean.
• Never use any chemicals that may damage the machine. Your commercial dishwasher user manual will have guidelines on which chemicals to use to clean the machine. Bleach and other types of chemicals should never be used in a commercial dishwasher.
• Schedule annual inspections. To ensure your dishwasher is performing optimally, a certified dishwasher technician should inspect the machine at least once a year. The technician will be able to replace any broken parts or diagnose other hidden problems you may not identify.
