Pass-Through & Hood Type Dishwashers

A pass-through dishwasher is a large-format warewasher where racks slide in from one side and exit clean from the other. The hood lifts over the rack rather than the rack sliding into a closed door. That design lets one operator load while another unloads, cutting turnaround time significantly during a busy service. Hood type and pass-through are often used interchangeably, though some models are wider or deeper to handle full sheet trays and utensils alongside crockery.

You'll find single-rack hood type models, wide-body units built for gastronorm trays and utensils, and twin-rack machines that process two racks simultaneously. Several Hobart Premax and Profi lines feature Vapostop vapour management and optional auto hood lift. Meiko, Washtech, Winterhalter, Eswood, Comenda, Eurowash, Wexiodisk, Aristarco and SMEG Professional each bring their own wash system designs, so there is a broad range to suit different kitchen layouts and throughput needs.

Both styles share the same hood-lift loading principle, so the real choice comes down to rack size, throughput and floor footprint. A single-rack hood type suits a cafe or mid-sized restaurant with moderate cover counts. A twin-rack or wide-body model suits high-volume venues processing large cookware alongside plates. If vapour control matters in a tight kitchen, look at models with built-in Vapostop or equivalent exhaust energy recovery, which several Hobart and Meiko units offer.

Start with your peak cover count and the types of ware you wash most often. A venue turning over a high volume of plates per service will need a machine with a faster cycle time and, potentially, a twin-rack configuration. Wide-body models handle full gastronorm trays without disassembly, which matters for catering and production kitchens. Measure your wash-up area carefully — these machines need clearance above for the hood to lift, plus inlet, drain and power connections on the correct sides.

Pass-through dishwashers typically require a dedicated electrical supply, a hot or cold water inlet, a floor drain and adequate overhead clearance for the hood. Some models include built-in booster heaters; others rely on an external hot water supply at a specified inlet temperature. Your plumber and electrician should review the model's data sheet before rough-in. Auto hood lift variants also need enough ceiling height above the machine for the hood to travel fully open.

Most pass-through dishwashers are designed to align with standard bench heights, but the machine footprint is larger than an under-counter model. You'll need infeed and outfeed bench space on both sides so operators can stage dirty ware and rack clean ware without crowding. Wide-body and twin-rack units take up more floor space, so map out the full bench run — including rack landing zones — before you order. Some brands offer matching inlet and outlet tables as accessories.

Daily cleaning typically involves removing and rinsing the wash arms, clearing the filter basket and wiping down the interior after service. Descaling frequency depends on your local water hardness — harder water areas need more regular treatment. Rinse aid and detergent dosing systems should be checked and refilled routinely. Most brands recommend a scheduled service by a qualified technician to inspect wash arm nozzles, door seals and chemical dosing pumps, keeping the machine running at its best between major services.

Hobart, Meiko, Washtech, Winterhalter and Eswood all have established service networks across Australia. Comenda, Eurowash, Wexiodisk, Aristarco and SMEG Professional are also supported locally through authorised service agents. We'd recommend confirming service coverage in your specific region before purchasing, particularly for regional or remote sites where technician call-out times can vary. Having access to local parts and trained technicians is worth factoring into your buying decision alongside the machine's purchase price.

Vapour management systems, such as Hobart's Vapostop, reduce steam released into the kitchen, which matters for ventilation and staff comfort. Auto hood lift removes the manual effort of raising and lowering the hood on every cycle. Heat recovery on the drain line can reduce energy consumption over a long service. Built-in water softeners are available on some models and are worth considering in hard-water areas. These features add to the purchase price but often reduce running costs and improve the working environment.

Prices vary considerably depending on rack size, cycle speed, energy recovery features and brand. Entry-level single-rack hood type models sit at a lower price point, while twin-rack wide-body units with auto hood lift and vapour management sit at the higher end.
