When you run a busy commercial kitchen, your dishwasher works just as hard as your staff—maybe even harder. It’s the unsung hero that keeps everything moving smoothly, making sure dishes, cutlery, and cookware are spotless and ready to use. But just like any piece of equipment, it needs regular TLC to keep performing at its best.
Here are some practical maintenance tips to help you avoid costly dishwasher breakdowns to extend the life of your commercial dishwasher.

1. Clean the Filters Daily
Grease, food scraps, and debris can clog the filters, making your dishwasher less effective and causing drainage issues. Make it a routine to remove and rinse the filters at the end of each day. This simple habit can save you a lot of trouble down the line.
2. Inspect and Unclog Spray Arms
Spray arms are responsible for distributing water evenly inside the machine. If they get blocked, your dishes won’t come out clean. Regularly check the nozzles and remove any build-up or debris to keep everything spraying smoothly.
3. Use the Right Chemicals
Not all cleaning products are created equal. Always use detergents, rinse aids, and cleaning products designed specifically for commercial dishwashers. Using the wrong chemicals can damage internal components and affect cleaning quality.
4. Monitor Water Temperature
Water that’s too cool won’t clean properly, while overheating can wear out parts faster. Make sure your dishwasher’s water temperature aligns with manufacturer guidelines—typically around 55°C for washing and 82°C for rinsing.
5. Descale Regularly
Hard water is the enemy of commercial dishwashers. Limescale can build up quickly, affecting performance and damaging heating elements. Set up a regular descaling schedule, especially if your area has high mineral content in the water.
6. Check Door Seals
Leaks not only waste water but can also be a safety hazard. Inspect the door seals regularly for wear and tear. If they’re cracked, loose, or look worn out, it’s time to replace them.
7. Run an Empty Cycle Weekly
Running a hot cycle with a dishwasher cleaner and no dishes helps clear out grease and grime from the inside of the machine. Think of it as a refresh for your dishwasher—it keeps everything running smoothly and smelling fresh.
8. Schedule Preventive Maintenance
Even with the best daily care, it pays to have a professional technician inspect your machine every few months. They can catch small issues before they become big (and expensive) problems.
Your commercial dishwasher is an investment—and one that deserves proper care. With a preventative maintenance plan, you’ll get better performance, cleaner dishes, fewer breakdowns, and a longer-lasting machine. In a fast-paced kitchen, that’s peace of mind you can’t put a price on.
