What maintenance schedule should I follow for a commercial ice machine?

Use a layered schedule so nothing gets missed:

Every day (end of shift): empty and wipe the bin lid and surrounding surfaces, wash and sanitise the scoop, check ice looks and smells normal, and keep the bin closed.

Weekly: clean high-touch parts (scoop holder, bin door/handle, splash areas), check the drain is flowing freely, and clean any accessible air intake vents.

Monthly: remove and clean washable air filters (if fitted), check water supply fittings for leaks, and inspect door seals and bin liner for damage.

Quarterly (or more often in hard-water areas): run a full descale and sanitise of the ice-making system following the manufacturer procedure, then deep-clean the storage bin.

Annually: schedule a professional service to confirm water system, refrigeration and safety checks, especially for high-volume sites.

If you notice slow production, small/soft cubes, off-odours, scale build-up, or slime in the bin, bring the deep-clean forward rather than waiting for the next planned interval.
