For single-temp machines, the water must be at least ______.

• A. 165 degrees F (74 C)
• B. 160 degrees F (71 C)
• C. 170 degrees F (77 C)
• D. 180 degrees F (82 C)

Answer: (A)

Single-temp machines sanitize using hot water alone, so the water must be hot enough and stay at that temperature long enough to kill bacteria on the dishes. The minimum temperature for this method is 165°F (74°C). Maintaining at least this temperature during the wash cycle ensures proper sanitization without needing a separate chemical sanitizer or rinse step. Higher temperatures like 170–180°F are used in other machine types or for different sanitizing methods, but for a single-temp machine the required minimum is 165°F.
