High-temperature commercial dishwashers must reach 180°F (82°C) at the final rinse to achieve proper sanitization per NSF and health department standards. Low-temperature chemical sanitizing machines must maintain proper chemical concentrations (chlorine, iodine, or quaternary). If your high-temp machine isn't reaching 180°F, it's not properly sanitizing and may fail health inspection. Call a technician immediately.

The hi-limit switch is a safety device that cuts power when fryer temperature exceeds safe limits. Common causes: faulty thermostat allowing oil to overheat, failing hi-limit switch itself, improper temperature settings, low oil level exposing heating elements, or carbon buildup insulating heating elements. Never bypass the hi-limit switch — it prevents fires. Call a technician to diagnose the root cause.

Combi oven steam issues are commonly caused by: clogged steam generator or boiler scale buildup, failed heating element in the steam generator, water inlet valve problems, or steam nozzle blockages. Mineral scale from hard water is the most common culprit and can be prevented with regular descaling. A combi oven specialist should inspect the steam system as improper repairs can damage the boiler.
