Do Commercial Dishwashers Need Hot Water? Mayers Gives You A Clear Answer
Oct 14, 2025| For restaurants, hotels, and catering businesses, commercial dishwashers are a must for smooth kitchen operations. A common question we get at Mayers (a professional commercial dishwasher factory) is: Do these dishwashers need hot water? The answer is simple-yes, hot water is a must, not an option. It directly affects how well dishes are cleaned, how hygienic they are, and how long your dishwasher lasts.
1. Hot water = faster, cleaner stain removal
Commercial kitchen dishes are covered in tough messes-dried egg, burnt oil, sticky sauces. Cold or warm water can't break these down well.
Hot water softens grease and loosens dried food quickly. When paired with detergent (at 120°F–140°F/49°C–60°C), it gets dishes clean in one cycle. No more re-washing by hand-saves your staff time and cuts labor costs.
2. Hot water = safe, bacteria-free dishes
Food service needs strict hygiene. Harmful bacteria like Salmonella and E. coli must be killed to meet health rules (e.g., FDA standards).
Hot water is a natural sanitizer. Most commercial dishwashers have a sanitization cycle that uses 180°F–195°F (82°C–91°C) water-this kills bacteria in seconds. Without hot water, even good detergent can't keep dishes safe for customers.
3. Hot water = longer dishwasher life
A commercial dishwasher is a big investment-you want it to last. Using cold water causes problems:
Undissolved detergent sticks to internal parts (spray arms, filters, pumps). Over time, this clogs parts and wears them out early. Hot water dissolves detergent fully, preventing buildup and keeping your machine running smoothly.
