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.

1) Check if the condenser unit is running. 2) Inspect condenser coils for dirt and debris — blocked coils are a common cause. 3) Ensure walk-in door gaskets are sealing properly. 4) Check if evaporator fan is running. 5) Look for ice buildup on evaporator coils (defrost system failure). If temperature is rising significantly, move temperature-sensitive inventory and call a technician immediately — this is an emergency situation.

Critical food safety temperatures: Cold holding — 40°F (4°C) or below for refrigeration; freezer 0°F (-18°C) or below. Hot holding — 140°F (60°C) or above for steam tables and food warmers. Cooking temperatures vary by food type (145°F-165°F). Dishwasher final rinse — 180°F (82°C) for high-temp machines. Any equipment consistently failing to maintain these temperatures is both a safety risk and a health code violation.
