Smeg SPD505AU Ecoline Professional Commercial Underbench Dishwasher (500x500mm Basket / HTR System / WaterMark Certified)

Streamline commercial scullery operations, eliminate back-of-house warewashing delays, and guarantee thermal sanitisation with the Smeg SPD505AU Ecoline Professional Commercial Underbench Dishwasher. Designed and manufactured in Italy backed by four decades of catering equipment engineering, this heavy-duty 578 mm wide undercounter warewasher processes up to 40 baskets (720 dishes) per hour. Combining a high-pressure HTR (High Temperature Rinse) atmospheric boiler system with a quiet 55.5 dBA double-wall chassis, it delivers spotlessly cleaned, food-safe plates, glassware, and GN 1/1 trays across busy cafes, restaurants, bars, aged care homes, and hospitality venues.

Constant 85°C Thermal Sanitisation with Smeg HTR Technology

Fluctuating mains water pressure often undermines final rinse temperatures in standard commercial dishwashers. The Smeg SPD505AU resolves this with its proprietary HTR (High Temperature Rinse) system, which pairs a dedicated internal rinse booster pump with an atmospheric break tank boiler (6-litre capacity). Independent of incoming mains water pressure fluctuations, the system guarantees a continuous, uniform water spray at a certified 85°C thermal sanitisation temperature (with a 60°C wash cycle), fully satisfying Food Standards Australia New Zealand (FSANZ) Standard 3.2.2 requirements for commercial hygiene and fast evaporative drying.

High-Output 40 Racks/Hour with 340 mm Loading Clearance

Designed for high-speed turnover during peak breakfast, lunch, and dinner rushes, the SPD505AU features three automatic electronic wash programmes (90, 150, and 240 seconds) plus dedicated self-cleaning and extra-rinse options. Standard 500 mm × 500 mm racks slide through a 340 mm vertical door clearance, easily taking tall beer steins, stemmed wine glasses, dinner plates, pasta bowls, and full-size GN 1/1 Gastronorm food prep trays directly from the kitchen pass.

Acoustic Dampening & Thermal Insulation (55.5 dBA Ultra-Quiet)

Operating a warewasher near open kitchen counters or quiet front-of-house dining spaces requires low acoustic disturbance. The SPD505AU is built with an insulated double-wall door and a partial double-skin AISI 304 commercial stainless steel body. This heavy-duty build drops operational sound to an ultra-quiet 55.5 dBA, while locking in thermal energy to minimise standby boiler reheat cycles and lower ambient kitchen heat.

Fully Integrated Pumping Suite & 4-Stage Scrap Filtration

The unit comes factory-fitted with all essential commercial plumbing pumps to streamline below-bench integration:

• Built-in Automatic Drain Pump: Discharges soiled wash water into elevated wall standpipes or under-sink plumbing spigots without requiring gravity fall.

• Peristaltic Detergent & Rinse-Aid Dosing Pumps: Electronically regulated dosing draws the precise amount of chemical per cycle, stopping chemical waste, cloudy glass film, and mineral spotting.

• 4-Stage Tank Filtration Network: High-density stainless steel surface filters and pump intake strainers catch food scraps, lemon seeds, and coffee grounds, keeping the 16-litre wash tank clean and protecting the wash pump impeller.

Single-Phase Commercial Power & Low 3.2L Water Efficiency

Consuming an economical 3.2 litres of fresh water per cycle, the SPD505AU reduces monthly utility overheads, chemical usage, and water heating demands. Engineered for commercial power circuits, the machine draws 3.5 kW on 230V/240V single-phase power (15A/16A dedicated commercial connection). Backed by a comprehensive 24 Months Parts and Labour Warranty, it delivers reliable Italian performance for hospitality operations.

Technical Specifications

Daily Care, Maintenance & End-of-Shift Sanitisation

To maintain wash performance, prevent scale build-up, and satisfy commercial hygiene compliance:

1. Power Isolation: Before cleaning internal chambers, removing wash arms, or emptying filters, switch off the appliance on the control facia and isolate the electrical supply at the wall isolator.

2. Automated End-of-Shift Drainage & Self-Cleaning: At the close of each service shift, activate the automated self-cleaning and drain cycle to evacuate the 16-litre wash tank completely. Never leave soiled water resting in the machine overnight.

3. 4-Stage Tank Filter Cleaning: Lift out the stainless steel scrap trays and the fine cylindrical pump intake filter. Rinse under running water in a scullery sink to clear trapped food particles, lemon seeds, and toothpicks before refitting.

4. Wash and Rinse Arm Inspection: Unclip or unscrew the upper and lower rotating wash and rinse arm assemblies weekly. Check all nozzles for limescale deposits or food debris, rinse the arms under clean water, and secure them back into place.

5. Chemical Feed Line Checks: Inspect the clear peristaltic detergent and rinse-aid pickup tubes weekly. Confirm that the suction weights sit submerged in the chemical drums and that tubing is free of dried, crystallised chemical blockages.

6. Water Treatment & Descaling: In Australian hard-water regions, connect the appliance to an approved commercial water treatment filter or softener. Run an approved descaling solution through the unit periodically to prevent limescale accumulation on heating elements and within the atmospheric boiler.

7. Exterior Stainless Steel Care: Wipe down external door panels, handle recesses, and the control facia daily using a soft microfibre cloth dampened with warm water and a neutral commercial cleaner. Avoid abrasive scouring pads, wire wool, or chlorine bleaches.

8. Washdown Safety: Never wash down the front or sides of the underbench unit with a high-pressure hose or commercial pre-rinse spray gun. Keep water away from the lower mechanical service compartment and electronic controls.

Kitchen & Bar Placement Guidelines

The Smeg SPD505AU is engineered for commercial wash-up passes, bar returns, and scullery stations:

1. Dedicated 15A/16A Power Supply: The unit requires 3.5 kW on single-phase 230V/240V power and requires a dedicated 15A or 16A commercial circuit connected to an appropriate breaker. Do not use domestic 10A-to-15A adaptors or standard extension cords.

2. Plumbing Supply & Dynamic Pressure: Connect the inlet hose to a 3/4-inch BSP water connection (recommended inlet temperature: 45°C to 50°C for fast cycle turnaround). Because the machine features an internal break tank and atmospheric boiler, it operates reliably even in venues with variable mains water pressure.

3. Drainage Connection: Thanks to the factory-fitted automatic drain pump, the waste discharge hose connects directly into a standard 40 mm standpipe or under-sink spigot located up to 600 mm above finished floor level. Ensure the drain hose is secured without kinks or tight bends.

4. Underbench Levelling: Slide the unit into its 600 mm undercounter opening and adjust the threaded levelling legs until the machine sits plumb and level. Proper levelling prevents water pooling and ensures the counterbalanced door closes with an airtight perimeter seal.

5. Tableware Pre-Scrapping: Always scrape large food solids, napkins, and garnishes into an organic waste bin before loading baskets. Pre-rinsing heavily soiled plates preserves the 4-stage filtration system and keeps wash tank water cleaner across multiple cycles.

Frequently Asked Questions

Can I plug this commercial dishwasher into a standard Australian 10 Amp power point?

No. The Smeg SPD505AU has a total electrical power rating of 3.5 kW to run the wash pump, tank element, and 6-litre atmospheric boiler simultaneously. It requires a dedicated 230V/240V 15 Amp or 16 Amp commercial electrical supply.

What is the benefit of the Smeg HTR rinse system?

Standard commercial dishwashers rely on incoming mains water pressure to push hot water through the rinse arms, which can lead to dropped temperatures and patchy rinsing if water pressure drops. Smeg’s HTR system uses an atmospheric boiler and a dedicated rinse booster pump to deliver constant water pressure and an exact 85°C sanitisation temperature on every cycle.

Can this unit wash standard GN 1/1 Gastronorm pans?

Yes. With its 340 mm vertical door clearance and 500 mm × 500 mm basket dimensions, the SPD505AU easily takes full-size GN 1/1 food prep pans and large dinner plates.

Does this dishwasher include detergent and drain pumps?

Yes. The machine comes fully configured from the factory with an automatic drain pump, electronic peristaltic detergent dispenser, and rinse-aid dosing pump, removing the need for external pump add-ons.

What is the noise level during a wash cycle?

Thanks to its double-wall insulated door and partial double-skin AISI 304 stainless steel casing, the unit operates at an ultra-quiet 55.5 dBA, making it well-suited for undercounter placement in open cafes, bars, and compact sculleries.

What warranty coverage is included?

The Smeg SPD505AU is backed by a comprehensive 24 Months (2 Years) Commercial Parts and Labour warranty across Australia.
