What To Look For When Buying A Restaurant Dishwasher

Running a restaurant efficiently involves investing in the right equipment, and one essential piece of equipment is a reliable commercial dishwasher. Choosing the right dishwasher can save you time, effort, and money in the long run. Here we'll discuss the key factors to consider when purchasing a restaurant dishwasher.


The first consideration when buying a dishwasher is its size. You need to ensure that the dishwasher you choose fits comfortably in your kitchen space. Measure the available area carefully, including height, width, and depth, to ensure a proper fit. Smaller kitchens may be looking for an undercounter model while larger restaurants might require a pass through or conveyor dishwasher. Keep in mind that a dishwasher that's too small may not meet your capacity needs, while one that's too large may be inefficient for smaller operations.

Capacity & Output:

The dishwasher's capacity and output are crucial factors to consider. Determine the average number of dishes, glasses, and utensils you need to wash per hour during peak times. Look for a dishwasher that can handle your required volume efficiently. Consider the number of racks and compartments it offers and its ability to accommodate different dish sizes and shapes.

Break Tanks, Drain Pumps & Water Softeners: 

When it comes to dishwasher functionality, break tanks, drain pumps, and water softeners are important features to consider. Break tanks prevent backflow of dirty water into the mains water supply, ensuring hygiene and compliance. Drain pumps assist in efficient water drainage, especially in areas where gravity flow is not feasible. Water softeners help combat limescale build-up, extending the lifespan of your dishwasher and ensuring spotless results.


The best commercial dishwashers offer more than standard cleaning. Look for other notable features that can enhance performance and efficiency such as:

  1. High-quality manufacture: Look for dishwashers built with durable materials and components that can withstand the demands of a busy restaurant environment.

  2. Superior insulation for added efficiency: Dishwashers with excellent insulation help retain heat and reduce energy consumption, resulting in lower utility bills.

  3. Eco programs: Some dishwashers offer eco-friendly programs that use less water and energy without compromising cleaning efficiency. This can be a valuable feature for environmentally conscious establishments.

Some commercial dishwasher brands offer features and programmes that are unique to that manufacturer. Always look out for advanced technology that will give enhanced hygiene or potential energy savings such as these:. 

  1. Winterhalter EnergyPlus exhaust air heat recovery: This innovative feature utilises the heat from the exhaust air to preheat the cold water inlet, reducing energy consumption by up to 15%.

  2. Sammic thermo-lock feature: This feature ensures dishes are properly sanitised by ensuring the rinsing cycle is only being carried out when ideal rinse water temperatures are reached.This effectively eliminates harmful bacteria and guarantees ultimate hygiene and optimal disinfection.


When purchasing a dishwasher, consider reputable brands known for their reliability, performance, and after-sales support. Brands that have been in the industry for a long time often have a track record of producing quality equipment.


A dishwasher with a solid warranty provides peace of mind, as it covers any manufacturing defects or malfunctions during the specified period. Look for warranties that offer comprehensive coverage, including parts and labour.


While price is important when it comes to sticking to budgets, it should not be the sole determining factor. A higher-priced dishwasher may offer advanced features, durability, and energy efficiency that can save you money in the long term. Consider the value and return on investment rather than solely focusing on the upfront cost.

Choosing the right dishwasher for your restaurant is essential to ensure smooth operations and consistent cleanliness. Consider the size, capacity, and output requirements of your establishment. Look for features that enhance efficiency, hygiene, and energy savings. Don't forget to consider the brand's reputation, warranty coverage, and the overall value the dishwasher provides. By carefully evaluating these factors, you'll be well on your way to selecting a reliable and efficient dishwasher that meets your restaurant's needs.
