How often does a Hoshizaki ice machine need to be cleaned?

At least every six months to keep the warranty valid, and quarterly for high-volume kitchens, poor water or hot back-of-house locations. We document every cleaning for your records.

My Hoshizaki stopped making ice overnight. What should I check?

Check the water shutoff and filter head, look for a service light on the board, feel whether the condenser is hot and clogged, and make sure the bin control is not blocked by ice. If all of that looks right, call your regional dispatch line.

Do you carry Hoshizaki parts on the truck?

Yes. Our trucks carry the common Hoshizaki failure parts, so most repairs close on the first visit instead of waiting for a part to ship.

Hoshizaki ice machine repair

Oasis Preferred Maintenance is a Hoshizaki certified service rep (HCSR), and our technicians are factory trained and certified on Hoshizaki equipment. That means your Hoshizaki gets diagnosed by someone who trained on the platform, repaired with the parts it was built with, and documented the way the manufacturer expects.

Our Hoshizaki status

Factory trained & certified — HCSR service rep.

Because we are factory authorized, warranty repairs on a covered Hoshizaki are processed directly through the manufacturer — you are not paying out of pocket and then chasing a reimbursement.

Why HCSR status matters on a Hoshizaki

A Hoshizaki in a busy kitchen is rarely idle, so when it stops the clock is already running. Hoshizaki control boards keep fault history, and a certified tech reads that history before pulling a single panel. That shortens the diagnosis and keeps us from replacing parts that were never the problem.

Our trucks carry the common Hoshizaki failure parts, so most calls close on the first visit instead of turning into a second trip while a part ships. If a repair is covered by warranty, we handle the paperwork with the manufacturer so the machine is back in service and you are not left holding the invoice.

Field diagnosis

Common Hoshizaki problems we fix

Not harvesting or making no ice

Usually water supply, a stuck water valve, a dirty evaporator or a board in a fault state. We read the stored fault history first, then test the harvest cycle instead of guessing.

Low production or small cubes

Scale on the evaporator, a restricted water flow, a clogged condenser or a weak refrigeration circuit all shrink cubes. We measure output against what the unit should make and fix the cause.

Cloudy ice and scale buildup

Cloudy cubes are almost always water chemistry — high dissolved solids or a filter past due. A descale and the right filtration fixes the ice and protects the evaporator.

Water leaking on the floor

Clogged or poorly sloped drains, a cracked or dislodged water trough, or an inlet valve that will not fully close. We find the source rather than mopping around it.

Service light or fault on the board

A fault light is the machine telling you something specific. We pull the code history, confirm the reading with real measurements and repair the component that triggered it.

Bin full but still running — or never stopping

A blocked, dirty or failed bin control lets the machine overfill or shut down early. We clean or replace the control and verify it cycles correctly before we leave.

Hoshizaki cleaning & sanitation

Hoshizaki, like the other major manufacturers, calls for a full cleaning and sanitation at least every six months to keep the warranty valid — quarterly in high-volume or hot kitchens. Our ice machine cleaning service tears down and sanitizes every surface the ice touches and leaves a dated report for the health inspector.

Water filtration that protects your Hoshizaki

Scale is what shortens a Hoshizaki's life more than anything else, and manufacturers exclude scale and sediment damage from warranty coverage. Filtration matched to your water test protects the evaporator, keeps cubes clear and keeps warranty claims clean.

Preventative maintenance memberships

A preventative maintenance membership puts your Hoshizaki on a schedule — cleanings, filter changes, harvest-cycle checks and condenser cleaning — with priority same-day dispatch ahead of non-members when something does go wrong.

Replacing or leasing a machine

If a Hoshizaki is near the end of its life, we will run repair-versus-replace numbers honestly. Leasing bundles new equipment, filtration, cleanings and service into one monthly cost with no capital outlay.
