RW Heating Air Plumbing & Electrical

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.

A comprehensive PM program should include: scheduled inspections at manufacturer-recommended intervals, cleaning of condenser coils and filters, calibration of temperature controls, inspection and testing of safety systems, lubrication of moving parts, replacement of wear items (gaskets, filters, belts), refrigerant level checks, combustion analysis for gas equipment, and detailed documentation for each visit. Avoid programs that are just a visual inspection without hands-on service.

Installation costs vary widely: single appliance installation $300-$2,000 depending on complexity (simple drop-in vs. gas/electrical connections required); complete kitchen buildout $15,000-$75,000+. Costs include equipment setting, utility connections (gas, electric, water, drain), ventilation hookup, and commissioning. Always get installation quotes separate from equipment costs — some dealers include installation, others charge separately.
