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.

Most commercial kitchen equipment installations require permits: gas appliance permits for any gas connection work, electrical permits for new circuits or panel changes, plumbing permits for water and drain connections, and health department approval for new food service operations or major renovations. Requirements vary by jurisdiction — your installer should know local requirements. Operating without required permits can result in fines and forced closure during inspections.

Signs of a refrigerant leak: unit runs but doesn't reach temperature, ice buildup on evaporator coil, hissing or bubbling sounds from refrigerant lines, oily residue near connections or fittings, and higher than normal electricity consumption. Only EPA-certified technicians can legally handle refrigerant. If you suspect a leak, call a technician promptly — operating a refrigerator with low refrigerant damages the compressor.
