Preventive maintenance frequency depends on the equipment and usage volume. As a general guideline: fryers and ovens should be inspected every 3-6 months; refrigeration equipment annually or semi-annually; ice machines every 6 months (including cleaning and sanitizing); exhaust hoods quarterly to semi-annually per NFPA 96; and dishwashers quarterly. High-volume operations benefit from more frequent service intervals.

Chemical dispensing problems are typically caused by: clogged or faulty chemical pumps, incorrect dilution ratios, empty chemical containers, broken injection lines, or control board issues. In low-temperature machines, proper chemical concentration is essential for sanitization — test strips should verify concentration after every repair. Many chemical distributors offer free testing; alternatively, a technician can verify and repair the dispensing system.

Commercial ice machines should be professionally cleaned and sanitized every 6 months at minimum, or more frequently in hard water areas. The FDA Food Code requires ice machines to be clean and sanitized to prevent mold, slime, and bacterial growth. Between professional cleanings, staff should clean the exterior, ice bin, and scoop holder regularly. Many operators who skip cleaning face costly repairs from scale buildup and potential health code violations.
