Underbench dishwashers fit under standard 900mm commercial benches and provide compact, high-throughput wash cycles for cafés, bars, small restaurants, office kitchens and reception areas. Hospitality Connect supplies undercounter dishwashers and glasswashers from Eswood, Winterhalter, Apuro, Hobart and Smeg - all configured for AU 240V 10A or 15A circuits with HACCP-compliant rinse temperatures.
Types of underbench dishwasher
- Glasswashers (400mm rack): 90-180 second cycles; for bars and cafés running glassware-only volume. Lower water temperature than dishwashers preserves stem glass.
- Dishwashers (500mm rack): 90-180 second cycles; for cafés and small restaurants running plates, cups and cutlery.
- Combination glass/dish (500mm): Multi-program units; switches between glass and crockery cycles. Best for venues running both.
- High-temperature sanitising units: 82 degrees C+ rinse temperature; chemical-free sanitisation through heat alone.
- Pumped-drain models: For installations where the drain is above the unit; eliminates need for raised plinth.
Sizing and throughput
A 400mm glasswasher cycles 30 racks per hour - sufficient for a bar serving up to 200 covers per night. A 500mm dishwasher cycles 30-60 racks per hour - suits cafés up to 80 covers per service. Small restaurants over 80 covers should step up to passthrough hood machines (separate collection). Cycle time is the key metric: 90-second express cycles handle peak volume; 180-second sanitising cycles deliver HACCP-compliant rinse temperature. Cup/glass capacity per rack: 18 standard plates or 36 wine glasses or 25 mugs.
Plumbing and energy notes
- Hot water feed: Most commercial machines need 55-60 degrees C inlet, not cold. Undersized HWS chokes cycle time and rinse temperature.
- Drain falls: Floor waste below the machine outlet; pumped-drain models add cost but solve hard cases.
- Power requirements: Glasswashers run 10A 240V; dishwashers 15A 240V. Confirm circuit before delivery.
- Detergent and rinse aid: Both must be dosed - rinse aid alone reduces water-spotting and improves drying.
- Water hardness: Hard-water areas need water softener inline; lime scale damages elements within months.
Underbench placement matters: confirm clearance to the bench top (most units need 850-880mm under-bench clearance), position the unit close to the soiled-rack landing area to minimise dripping across the kitchen floor, and plan a dedicated detergent and rinse-aid storage cupboard within reach. Don't share the dishwasher circuit with another high-load appliance (induction, fryer) - simultaneous load trips the breaker. For high-volume bars running back-to-back glass cycles, an inline water softener pays for itself in element life and glass clarity within 12 months.
