Hoshizaki maintenance:
complete checklist
A Hoshizaki refrigerator or freezer lasts 12 to 15 years with good maintenance. Without maintenance this halves. This checklist reduces your breakdown risk, lowers energy consumption and extends the service life of your units.

Most important maintenance
Monthly: vacuum condenser + check door seal. Every 3 months: replace ice maker water filter + thorough condenser cleaning. Every 6 months: ice maker disinfection + full technician inspection. Never neglect condenser maintenance – it is the most common cause of failure.
Daily maintenance: 5 minutes per day
Daily maintenance of your Hoshizaki units takes five minutes and prevents 80 per cent of the most common faults. These tasks should be part of your kitchen team's fixed end-of-shift routine.
Weekly: 15 minutes
Weekly maintenance focuses on the components that govern airflow and filtration. Set a fixed time (e.g. Monday morning before service starts) so nothing gets forgotten.
Monthly: condenser is critical
A dirty condenser is the primary cause of premature failure in Hoshizaki refrigeration. A 3 mm dust layer increases energy consumption by 30 per cent and puts extra strain on the compressor. Monthly cleaning is essential.
Every 3 months: water filter and deep clean
Every 3 months the water filter of your ice maker must be replaced, regardless of visible condition. A saturated filter reduces ice production by up to 20 per cent and causes limescale deposits on the evaporator.
Annually: call in a technician
Annually an authorised Hoshizaki technician must carry out a full inspection of your units. This is beyond DIY maintenance: specialist tools and knowledge of the refrigeration circuit are required. JMGT offers this as a one-off service or within a maintenance contract.
Warning signs: call service immediately
Certain signals indicate an imminent fault and must be reported to service immediately – not when the unit has completely failed. Acting early prevents food loss and often saves repair costs.
Maintenance contract: what you get
A maintenance contract at JMGT for Hoshizaki units costs on average €175 to €425 per year depending on type and number of units. This is generally cheaper than a repair outside the contract and ensures HACCP requirements are met.
Included: 1 or 2 inspections per year, priority on breakdowns, original Hoshizaki spare parts, HACCP reporting, discount on out-of-contract work and advice on modernisation or replacement.

Frequently asked questions
How often does a Hoshizaki ice maker need to be cleaned?
A Hoshizaki ice maker must be fully disinfected at least every 6 months, in hard water areas every 3 months. Daily: rinse storage bin with hot water. Weekly: clean filter grille and drip tray.
How often does the condenser of my Hoshizaki refrigerator need to be cleaned?
The condenser must be vacuumed or blown out with compressed air every 3 months. A dirty condenser increases energy consumption by 15–30 per cent and is the most common cause of compressor failure in Hoshizaki units.
What do I do if my Hoshizaki stops cooling?
Check first: 1) is the condenser clean, 2) does the door close properly (check door seal), 3) is there sufficient ventilation around the unit (minimum 5 cm clearance). If it still does not work: call JMGT for service – do not attempt repairs yourself, as this will void the manufacturer warranty.
How long does a Hoshizaki last with good maintenance on average?
With proper maintenance a Hoshizaki refrigerator or freezer lasts 12 to 15 years, ice makers typically 10 to 14 years. Without regular maintenance (especially condenser and water filter) this drops to 6 to 8 years. Proper maintenance discipline doubles the service life.
Can I take out a maintenance contract with JMGT?
Yes. For Hoshizaki units we have supplied, we offer maintenance contracts with 1 or 2 inspections per year. Including preventive maintenance, calibration and HACCP reporting. Rates depend on unit type and frequency.
Do water filters on my Hoshizaki ice maker need to be replaced?
Yes, every 6 months or after 18,000 litres of water throughput. A saturated water filter leads to limescale deposits on the evaporator and reduced ice production. JMGT supplies original Hoshizaki water filters and handles replacement within the maintenance contract.
