A Hobart dishwasher—whether an undercounter, hood, or conveyor model—cuts cleaning time and keeps plates hygienic in cafés, pubs and commercial kitchens. I've put together what Australian kitchens should check in 2026 — setup, daily operation, sanitation targets, likely costs in AUD, who can help and common mistakes to avoid. Save this page and tick the checklist before each service so you don't miss anything.
Quick reference
- Thermal machines usually need a final rinse close to 82°C, while low‑temp units rely on a chemical sanitiser — always follow the manufacturer's dose and label.
- Expect undercounters to use a few litres per rack—often around 3–6 L; hood and small conveyors typically use a little less per rack, depending on the model.
- Power: undercounter ~0.6–1.5 kWh per cycle; conveyor higher depending on throughput.
- Clean filters and wipe seals every day, check chemical levels each month and book a full service about every 6–12 months.

Prerequisites
Before you run a Hobart dishwasher, make sure these items are in place.
1. Correct model and installation. Hobart makes undercounter, door/hood and conveyor machines. Installation must meet local plumbing and electrical rules. If a technician fitted the machine, keep their installation certificate and the wiring diagrams with your maintenance records.
2. Water and power specs. Most commercial Hobart undercounter machines need a 15–20 amp supply and a mains hot water feed or booster for high‑temp models. Confirm the data plate or manual for exact volts and amps.
3. Chemicals and dosing.
Only use detergents, rinse aids and sanitisers approved by the manufacturer to protect performance and warranty. For low‑temp machines you’ll use a chemical sanitiser dosed by a pump. Keep spare chemical contracts and material safety data sheets (MSDS) accessible.
4. Staff training and HACCP. Operators should know basic HACCP steps and local food safety rules. Refer to Food Standards Australia New Zealand at https://www.foodstandards.gov.au for national requirements.
Step-by-step: Daily operation (undercounter/hood models)
Follow these steps every service day. Numbered steps assume the dishwasher is installed, powered and plumbed.
- Pre‑start checks: Check water supply valve is open, chemical tanks contain product, and filters are seated. Confirm waste trap isn't blocked.
- Scrape and pre‑rinse: Remove major food scraps. Use a low‑pressure pre‑rinse to reduce solids — this keeps filters and pumps from blocking and lowers chemical use.
- Load correctly: Place cutlery handles down, bowls angled to allow water run‑off, and plates facing the centre. Don’t overload or nest items — that cuts wash coverage.
- Select program: Choose ECO, Standard, or Heavy based on soil level. ECO uses lower energy and water but may need longer cycles for thick soils.
- Start cycle and monitor: Watch the first minute to confirm water fills, spray arms rotate and there’s no unusual noise. If the machine is a thermal sanitiser, final‑rinse temperature should hit ~82°C for effective sanitisation.
- Unload after cooling: For thermal machines, wait until racks are cool enough to handle. For chemical sanitised racks, handle with clean gloves to avoid recontamination.
Step-by-step: Low‑temp machines with chemical sanitiser
Low‑temp machines run cooler—often around 50–60°C—and rely on an automatic dosing system to feed the sanitiser.
- Check dosing settings: Confirm the dosing pump is running and set to manufacturer‑recommended rates. Record settings daily in the log.
- Measure sanitizer: Test the rinse concentration with test strips or a meter. Target concentration varies by product; many are in the 50–200 ppm range. Follow the chemical label and Hobart recommendations.
- Maintain contact time: Ensure cycle length and dosing deliver the required contact time for the chemical to sanitise.
Maintenance: weekly, monthly and annual
Daily: empty and clean filters, scrape trays, wipe seals, flush chemical lines for a minute at the end of service if instructed.
Weekly: remove and clean spray arms, check door gaskets, descale if water is hard. Hard water increases scale — treat with a water softener if needed.
Monthly: test rinse aid and detergent levels; check dosing pump calibration; inspect electrical connections visually.
Every 6–12 months: book a Hobart‑trained technician for a service. Plan on roughly $200–$450 plus GST for a routine preventative service, but costs vary by state, machine and the terms of your service contract. Keep service records — they're often needed for warranty claims.
Costs and running estimates (Australia, 2026)
These are typical 2026 Australian estimates; actual numbers depend on model and usage.
Right now, purchase: a new Hobart undercounter dishwasher often starts around AUD 6,000–10,000 for basic models; hood and small conveyor machines commonly range AUD 8,000–25,000. Larger conveyors for high‑volume kitchens can be AUD 30,000+. Prices exclude installation, GST and chemical contracts.
Installation: plumbing and electrical connection usually add AUD 300–1,200. If a hot‑water booster is needed for thermal sanitising, budget AUD 1,000–3,500 for equipment and labour.
Operating costs: expect water use of 3–6 L per rack (undercounter) and energy around 0.6–1.5 kWh per cycle. Using an electricity rate of about $0.30–$0.40/kWh, a cycle that draws 0.6–1.5 kWh will cost roughly $0.18–$0.60 in energy alone. Add water and sewer charges and chemicals — heavy use kitchens can spend several hundred dollars a month on consumables.
Financial support: small businesses can check federal and state assistance schemes via Services Australia (https://www.servicesaustralia.gov.au) and state small‑business portals for any energy efficiency grants or rebates that might apply to replacing old equipment.
Tips
- Keep a log book with daily checks: detergent levels, dosing pump operation, and any faults. That saves time at inspection and proves due diligence for health audits.
- Use Hobart‑approved detergents and follow MSDS instructions. Off‑brand chemicals can damage seals and void warranties.
- Fit a water softener if hardness is over 200 ppm — scale damages heating elements and spray arms.
- Measure final rinse temperature with an infrared thermometer for thermal machines. For low‑temp machines, use test strips for chemical concentration each shift.
- Train casual staff on basic loading and pre‑rinse — poor loading is the biggest cause of poor wash results.
Common mistakes to avoid
1. Overloading racks — it’s tempting to push more through, but nesting plates or crowding spoils wash coverage and increases rewash rates.
2. Skipping filter and pre‑clean work — solids left in the machine block pumps and shorten equipment life.
3. Wrong chemical dosing — under‑dosing leaves bacteria; over‑dosing wastes money and can corrode parts. Test and record concentrations.
4. Ignoring temperature or sanitizer checks — health inspectors expect proof. For thermal machines, final rinse must reach sanitising temp; for chemical systems, documented ppm checks are necessary.
5. DIY electrical or plumbing changes — always use licensed trades. Incorrect work voids warranties and can breach workplace safety laws.
Alternatives and quick comparisons
Domestic vs commercial: Domestic dishwashers are cheaper but not built for continuous use. Hobart commercial machines are built for throughput and heavy soils — the higher initial cost pays off in labour savings and reliability.
High‑temp (thermal) vs low‑temp (chemical): Thermal machines rely on high final rinse temperature (~82°C) and need a hot‑water booster in many kitchens. Low‑temp models use chemical sanitisers and require dosing pumps and chemical monitoring. Choose based on existing hot‑water capacity, labour patterns and local health rules.
