What does this commercial ice machine annual checklist cover?

15 items across 5 sections, covering shutdown and lockout, descale and evaporator, harvest and production, refrigeration and electrical, and more. Each item spells out what the person walking the job is actually looking for, not just a box to tick.

Who should run this inspection?

The refrigeration service tech on the annual service visit.

When in the schedule should this walk happen?

Once a year. The descale is what keeps mineral off the evaporator so cubes still release cleanly and full.

Why do these items ask for a photo?

9 of the 15 items call for photo evidence, 10 photos in all. A checklist answer without the photo is a claim; the photo is what makes the record worth something in a dispute and lets a reviewer approve work without re-walking the job.

What most often fails a commercial ice machine annual inspection?

Machine descaled with a quick rinse while scale stays baked onto the evaporator, so cubes come out cloudy and thin. Slow, incomplete harvest blamed on the water when the harvest sensor or hot-gas valve is actually at fault. Nobody measures daily output, so a unit quietly making half its rated ice keeps limping until a rush runs the bin empty.

Can I use this checklist in RTI?

Yes. Start a free RTI workspace, build this list as a checklist, and the Photo Gate holds the submit button until every mandatory item is answered and its photos are attached. Approved inspections roll into a branded turnover package with a tamper evident audit trail.

Commercial ice machine annual maintenance checklist

The annual ice machine service is the deep pass: the measurements, cleanings and tests a quarterly round doesn't reach. This checklist keeps the full service on record with the photos that make it defensible later. Work is commonly verified against manufacturer's published instructions, the applicable health and safety code. Confirm the edition your authority having jurisdiction has adopted.

The checklist

Every item, and the photo evidence it needs

The photo count on each row is what RTI would require before the item can be submitted. Work the list here and watch the gate hold, or load it into RTI and let it enforce the real thing.

Shutdown and lockout

Kitchen told of the downtime and ice use from the bin stopped
Kitchen manager told how long the machine is down, backup ice arranged, and staff told not to scoop from the bin until it is cleaned, sanitized and making ice again.
No photo
Every supply locked out before the panels come off
Machine and remote condenser power locked, tagged, proven dead. Powered checks (descale, sanitize, harvest, output, amps): covers on, people clear, locks off by whoever hung them, re-locked.

Descale and evaporator

Full nickel-safe descale run through the water circuit
Approved descaler cycled per the instructions, evaporator and distributor rinsed clear of mineral, no scale left at the cube pockets.
Water distribution even across the evaporator
Every pocket filling evenly during freeze, distributor holes clear, no dry spots leaving partial cubes.
No photo
Water circuit and level control checked after descale
Float or probe clean and controlling the fill, and where fitted the water pump at full flow with a clear impeller and the purge or dump valve seating without leak-by.

Harvest and production

Harvest cycle observed start to finish
Cubes release clean and complete, harvest not dragging, hot-gas valve and thickness sensor responding correctly.
No photo
Daily production measured against the rating
A weighed or timed batch checked against the nameplate output for the incoming water temperature, shortfall investigated.
Bin full control proven to stop ice production
Bin thermostat, curtain switch or level sensor tripped as the manufacturer describes, machine stopping at the end of the cycle and restarting once cleared.
No photo

Refrigeration and electrical

Refrigerant circuit checked by eye for oil and rubbing lines
Tubing, joints and service ports dry with no oily dust, no line rubbing the frame; any suspected leak or charge work goes to a certified refrigerant technician.
Compressor amps and supply voltage read against the nameplate
Read during freeze under the site's energized-work procedure and PPE, within the nameplate range, condenser fan amps included where the unit has one.
Wiring, contactor and terminals inspected once re-locked
With the machine re-locked, contacts, terminals and harness checked for heat marks, chafe and water tracking, connections checked tight with any loose ones tightened.

Sanitation and housekeeping

Full sanitize of bin, water path and components
Sanitizer run through the water circuit and bin per the instructions, all removable parts cleaned, gasket sound.
Clearances kept clear around the unit
No storage crowding the condenser intake, service side accessible, drain line routed with an air gap.
Locks removed and the first harvests dumped after sanitizing
Panels and covers on, locks removed by whoever hung them, machine making ice again, and the first harvests after the sanitizer discarded rather than served.
No photo
Annual results and output reported to the kitchen and owner
Kitchen told when ice is safe to use, and the descale, amp readings, measured output and any refrigerant referral filed against the machine for next year.
No photo

What usually sends this back

The failures are almost always the evidence, not the work

Machine descaled with a quick rinse while scale stays baked onto the evaporator, so cubes come out cloudy and thin.
Slow, incomplete harvest blamed on the water when the harvest sensor or hot-gas valve is actually at fault.
Nobody measures daily output, so a unit quietly making half its rated ice keeps limping until a rush runs the bin empty.
