Restaurant Ice Machine Maintenance
in Alhambra, CA

FDA Food Code and most manufacturer specifications require cleaning and sanitizing at minimum every six months. In Alhambra, where tap water runs 11–17 GPG, many high-volume operators — particularly dim sum halls and hot pot restaurants — benefit from quarterly descaling even if the full sanitization cycle stays semi-annual.

Inspectors look for a written cleaning log showing the service date and confirming the machine was sanitized. They also visually inspect the bin interior and evaporator area for slime or scale. A missing log is a citable violation regardless of how clean the unit appears.

Alhambra water tests at 11–17 grains per gallon — very hard by any standard. Scale deposits on the evaporator reduce ice production, force the compressor to work harder, and create rough surfaces where biofilm colonizes faster. Descaling is not optional maintenance here; it's the primary way to protect both the equipment and the ice quality.

Cleaning and sanitizing removes biological contamination — slime, biofilm, mold — using a food-safe cleaner and sanitizer applied to all ice-contact surfaces. Descaling uses an acid-based solution to dissolve mineral deposits from the evaporator and water system. Both steps are needed; Alhambra's water hardness means descaling is as important as the sanitization cycle.

LA County Environmental Health can require the machine to be taken out of service until it is cleaned and a log is available. For a restaurant on the Main/Garfield corridor running through a busy dinner service, that means no ice — a significant operational hit. Staying current on documentation avoids that scenario entirely.

LA County's requirement is documentation of cleaning and sanitizing per manufacturer specifications — if you follow the manufacturer protocol precisely and keep a dated log, a self-performed cleaning can satisfy the record-keeping requirement. In practice, most operators find that hard-water descaling and evaporator access require a technician, and that a third-party service record is easier to produce under inspection pressure.

Hard water affects ice machines, steamers, and dishwashers simultaneously. Operators running dim sum carts or Sichuan hot pot who descale the ice machine are often overdue on the steamer and dish machine as well. Coordinating those cycles together reduces the total number of service visits and prevents a surprise violation on a piece of equipment that shares the same water supply.

Boh coordinates service through vetted local vendors and can typically schedule within a few business days for non-emergency visits. If an inspection is imminent or a machine has been flagged, contact Boh directly — priority scheduling is available for compliance-urgent situations.
