Posted by Ollie Nelson on

Welcome to our comprehensive guide on commercial dishwashers and glasswashers in the UK market. In this informative article, we aim to equip you with the essential knowledge and terminology required to make well-informed decisions when selecting the right commercial dishwasher or glasswasher for your establishment. Whether you manage a pub, bar, or restaurant, grasping the various styles and sizes available will enable you to optimise your operation and guarantee impeccably clean glassware and tableware for your customers.

Glasswashers: Elevating Glass Cleaning

Commercial glasswashers stand as indispensable equipment in establishments like pubs, bars, and restaurants, where a considerable volume of glassware necessitates efficient cleaning. These compact machines come in different sizes, predominantly featuring 350mm and 400mm baskets. Nonetheless, our exceptional Speedwash SW45 Glasswasher presents a 450mm basket option, offering a medium-sized alternative between the conventional 400mm and 500mm machines. The basket's size determines the glasswasher's capacity, specifying the number of pint glasses it can accommodate.

Glasswasher Capacity (Approximate):

  • 350mm basket – Up to 16 glasses
  • 400mm basket – Up to 20 glasses
  • 450mm basket – Up to 25 glasses
  • 500mm basket – Up to 30 glasses

(Capacity may vary based on glass type)

With a standard 13amp UK plug, these glasswashers boast straightforward installation and operation, bidding farewell to manual washing and welcoming a hassle-free glass cleaning experience.

Small Dishwashers (400mm Basket): Compact Cleaning Power

In situations where space poses a challenge, small dishwashers equipped with 400mm baskets, like the Advantage AD40 or Speedwash SW40, emerge as saviours. These versatile machines are perfect for cramped quarters and deliver comparable cleaning performance to glasswashers. Featuring a rotating upper wash arm, they guarantee thorough cleaning of snack plates, side plates, and saucers. It's noteworthy, however, that the clear entry height may restrict the washing of larger crockery items. Nevertheless, owing to their compact dimensions and the convenience of a standard 13 Amp UK plug, these small commercial dishwashers serve as an excellent choice for establishments with limited space.

Large Dishwashers (500mm Basket): High-Volume Cleaning Powerhouses

For establishments necessitating a greater capacity and the ability to clean larger crockery items, large commercial dishwashers with 500mm baskets emerge as the ideal solution. These under-counter, front-loading dishwashers offer a similar cleaning performance to glasswashers and small dishwashers but come with the added advantage of accommodating bulkier items. They can be conveniently situated under work surfaces or on dishwasher stands, affording flexibility in terms of installation. With various wash cycle time options and power specifications, these large dishwashers are meticulously crafted to meet the demands of high-volume operations.

Our extensive array of 500mm basket commercial dishwashers caters to diverse washing requirements. The Speedwash SW50 offers an affordable yet efficient undercounter dishwasher capable of handling up to 800 plates per hour. The Advantage AD50 incorporates cutting-edge water and energy-saving technology, minimising operational costs without compromising on performance. The Advantage range also introduces a compact version, the AD50 Compact, designed for bustling establishments that necessitate the capacity of a 500mm dishwasher while grappling with limited space.

Pass-Through Dishwashers: Efficiency and Versatility Combined

Pass-through dishwashers, also recognised as hood dishwashers, are conceived with efficiency and versatility in mind. Their lift-able hood design simplifies loading and access, and these machines can be configured to operate in a 90-degree corner or straight-through setup, adapting seamlessly to varying kitchen layouts. Offering washing output akin to large under-counter machines, pass-through dishwashers come equipped with ergonomic features and additional capabilities to handle bulkier items, ensuring enhanced throughput.

Our pass-through dishwasher range comprises three models. The Speedwash SW55 and Advantage AD55 can accommodate 500mm baskets and can wash up to 1200 plates per hour each. The Advantage AD60, our largest commercial dishwasher, accommodates a 600mm x 500mm basket and can wash up to 1440 plates per hour—a 30% increase compared to typical pass-through dishwashers.

Utensil Washers: Tackling the Toughest Cleaning Tasks

When it comes to cleaning bakery equipment and cooking utensils, specialised machines like utensil washers, tray dishwashers, pan washers, and pot washers come into play. These appliances offer increased entry height and larger basket sizes to accommodate a broad range of utensils. With flexibility in cycle time and power configurations, they provide the adaptability required to tackle even the most challenging cleaning tasks in commercial kitchens.

Conveyor Dishwashers: Streamlining Large-Scale Cleaning Operations

For large-scale cleaning of dishes, glasses, and cutlery, conveyor dishwashers—also known as rack dishwashers—emerge as the ultimate solution. These machines employ a conveyor system that automates the washing and depositing of clean items. With customizable specifications tailored to individual customer needs, conveyor dishwashers offer unparalleled efficiency and productivity for high-volume operations.


Selecting the appropriate style and size of commercial dishwasher or glasswasher is pivotal for the seamless operation of your pub, bar, or restaurant. Whether you opt for a glasswasher, small dishwasher, large dishwasher, pass-through dishwasher, utensil washer, or conveyor dishwasher, comprehending the array of options available empowers you to make an informed choice.
