The Ultimate Buying Guide for Dishwashers

What are the different types of dishwashers? 

When it comes to selecting the right dishwasher for your kitchen, you'll come across various types to consider. 

Integrated dishwashers

Slimline dishwashers

Freestanding dishwashers

Table top dishwashers

What’s the difference between a slimline and a full size dishwasher? 

In terms of capacity, full-size dishwashers excel due to their larger size. They can accommodate a greater number of dishes, glasses, and utensils in a single wash cycle, making them a preferred choice for larger households or families with substantial dishwashing needs. Slimline dishwashers, though still capable of handling a respectable quantity of dishes, have a smaller capacity relative to their full-size counterparts. Consequently, they are better suited for smaller households or kitchens where space is limited.

Space considerations are another crucial factor. Slimline dishwashers are specifically designed for kitchens with restricted space, making them an excellent fit for small kitchens, apartments, or narrow layouts where fitting a full-size dishwasher can be challenging. Full-size dishwashers, by contrast, require more floor space in the kitchen and may not be suitable for compact kitchen designs.

Lastly, there's a difference in energy and water usage. Full-size dishwashers tend to consume more water and energy per cycle due to their larger capacity. On the other hand, slimline dishwashers, being smaller in size, may use slightly less water and energy per load. However, the exact energy and water efficiency can vary depending on the specific models and their energy ratings.

In summary, the choice between a slimline and a full-size dishwasher hinges on factors such as kitchen size, household size, and dishwashing requirements. While full-size dishwashers excel in capacity, slimline dishwashers are designed to save space and are more suitable for smaller kitchens or locations with limited available space.

What different sizes of dishwashers are available?

Dishwashers are available in a range of sizes to cater to different kitchen layouts and household needs. 

Dishwasher width

The standard full-size dishwasher models are typically designed with a width of around 60 centimetres (cm), providing ample space for cleaning a substantial number of dishes in one go. However, if your kitchen space is limited, or if you're looking for a more space-efficient solution, you may want to consider slimline designs or table top dishwashers as viable alternatives.

Full-size dishwashers, with their 60cm width, are a dependable choice for households with a considerable volume of dishes to clean. They offer the convenience of accommodating larger pots and pans, as well as a generous quantity of plates, glasses, and utensils. This makes them particularly well-suited for families or those who frequently entertain guests, as they can efficiently handle sizable dishwashing loads.

On the other hand, slimline dishwashers provide a space-saving alternative for kitchens where every inch of space counts. These dishwashers typically have a more compact width, around 45 cm, making them a perfect fit for smaller kitchens, apartments, or any setting where space is at a premium. While they have a reduced capacity compared to full-size models, slimline dishwashers still offer a practical and efficient solution for daily dishwashing needs, making them an ideal choice for couples or individuals.

If space is an even greater concern, table top dishwashers offer the ultimate in compactness and portability. These miniature marvels can be placed on a countertop or a stable surface, requiring minimal installation effort. Table top dishwashers are especially useful for tiny kitchens or studio apartments, where full-size or slimline models might be impractical. While they have a smaller capacity compared to larger dishwashers, table top models are perfect for single individuals or small households with limited dishwashing requirements.

In summary, when selecting a dishwasher, it's essential to consider the available space in your kitchen, the volume of dishes you need to clean regularly, and your specific household needs. The choice between full-size, slimline, or table top dishwashers ultimately depends on these factors, ensuring that you find the perfect fit for your kitchen and lifestyle.

Dishwasher Capacity

Dishwasher capacity is typically measured in place settings, with a "place setting" representing the standard arrangement of dishes and utensils used by one person during a meal. This typically includes a dinner plate, a salad plate, a bowl, a glass, a cup and saucer, flatware (knife, fork, and spoon), and additional utensils like a dessert fork and knife.

Here's how dishwasher capacity and place settings are measured:

• Standard Place Settings: A standard full-size dishwasher is designed to accommodate a specific number of standard place settings, usually around 12 to 14. This means it can clean the dishes and utensils used by 12 or 14 people in a single wash cycle.

• Adjustable Racks: Dishwashers often feature racks and shelves that can be adjusted to fit dishes of various sizes and shapes. This flexibility can influence the total number of place settings a dishwasher can hold.

• Size and Configuration: Dishwashers are available in different sizes and configurations. Smaller slimline dishwashers may have a capacity of 8 to 10 place settings, while larger models can handle up to 16 or more place settings.

• Cutlery and Utensil Storage: Some dishwashers offer specialised cutlery trays or baskets that can impact overall capacity. These trays can free up space in the main rack for additional dishes.

• Additional Features: High-end dishwashers may include features like adjustable tines, fold-down shelves, and extra spray arms that can optimise space and potentially increase capacity.

When considering dishwasher capacity, it's important to bear in mind that the actual number of dishes and utensils you can fit may vary depending on their size and shape. Overloading a dishwasher can lead to less effective cleaning, so arranging dishes properly is essential to ensure a thorough wash.

In summary, dishwasher capacity is primarily measured in terms of place settings, with standard full-size models typically accommodating around 12 to 14 place settings. However, factors such as adjustable racks and specialised features can influence how effectively the space is used and the number of dishes a dishwasher can hold.

Are dishwashers more efficient than washing up

Yes, dishwashers are generally more efficient than washing up by hand in terms of water usage, energy consumption, and even cleanliness. Here are a few reasons why dishwashers are considered more efficient:

1. Water Conservation: Dishwashers are designed to use a specific amount of water for each cycle, and they recycle and filter this water efficiently. Washing dishes by hand often involves continuously running the tap, which can result in significant water wastage.

2. Energy Efficiency: Dishwashers are engineered to heat water to the optimal temperature for efficient cleaning, usually around 60-65°C. Hand washing often requires using hot water from the tap, which can be less energy-efficient, especially if the water heater is far from the sink.

3. Consistent Cleaning: Dishwashers use powerful jets and spray arms to ensure consistent and thorough cleaning of dishes, including hard-to-reach areas. Hand washing may not achieve the same level of cleanliness, and it's easier to miss spots or leave residues.

4. Sanitisation: Dishwashers can reach high temperatures during the drying phase, effectively sanitising your dishes and killing most bacteria and germs. Hand washing with hot water may not achieve the same level of sanitisation.

5. Time Efficiency: Using a dishwasher saves you time and effort. You can load it, press a button, and let it do the work while you attend to other tasks. Hand washing, on the other hand, can be more time-consuming.

6. Water Temperature Control: Dishwashers are equipped with thermostats to ensure the water reaches the right temperature for cleaning. Hand washing may involve guessing or inconsistent temperature control.

It's worth noting that the efficiency of a dishwasher depends on various factors, including the dishwasher's age and energy efficiency rating, how full it is, and the settings you use. However, in most cases, modern dishwashers are designed to be environmentally friendly and cost-effective compared to washing dishes by hand, especially when used efficiently.

How to care for your dishwasher

Dishwashers are hardworking kitchen appliance that deserves a little TLC to keep it running smoothly. Proper care not only extends its lifespan but also ensures consistently clean and sanitary dishes. Here's a general guide on how to care for your dishwasher, covering daily maintenance, dishwasher cleaning, and loading tips:

Loading a dishwasher:

• Properly Arrange Dishes: Load dishes with the soiled side facing the spray arms. Plates should go on the bottom rack, with larger items like pots and pans along the sides. Glasses, cups, and smaller items should go on the top rack.

• Avoid Overcrowding: Ensure there's enough space between items for water and detergent to circulate. Overcrowding can lead to inefficient cleaning.

• Secure Utensils: Place utensils with handles down to prevent water spray from getting trapped. Use the utensil basket or rack to keep them separated.

• Be Mindful of Dishwasher-Safe Items: Check labels for dishwasher-safe items. Delicate or non-dishwasher-safe items should be hand-washed to prevent damage.

Daily maintenance for a dishwasher:

• Scrape Food Residue: Before loading your dishes, scrape off excess food into a bin or compost. This prevents food particles from clogging the dishwasher's filters and spray arms.

• Rinse Heavily Soiled Items: For dishes with stubborn or dried-on food, consider giving them a quick rinse before loading. This can prevent food debris from circulating in the dishwasher during the wash cycle.

• Run Full Loads: Dishwashers are most efficient when fully loaded. Wait until you have a full load before starting a cycle to conserve water and energy.

How to clean a dishwasher:

• Clean the Filter: Check your dishwasher's user manual to locate the filter. Remove it and rinse it under warm water to remove trapped debris. Depending on your dishwasher model, you may need to clean it monthly or as needed.

• Wipe Down the Interior: Periodically, wipe down the interior of the dishwasher, including the door gasket and seals. Use a damp cloth or sponge to remove any residue or stains.

• Clean the Spray Arms: Inspect the spray arms for clogs. Remove them if possible and rinse them under warm water. A toothpick or small brush can help dislodge any debris stuck in the spray arm nozzles.

• Deodorise: To remove odours, place a dishwasher-safe cup of white vinegar on the top rack and run a hot water cycle. Alternatively, you can use a commercial dishwasher cleaner.

By following these daily maintenance routines, periodic cleaning steps, and loading guidelines, you'll keep your dishwasher in top condition and enjoy spotless dishes with every cycle. A well-maintained dishwasher not only saves you time and effort but also contributes to a more sustainable and efficient kitchen.

Why do dishwashers need salt and rinse aid?

Dishwashers utilise salt and rinse aid for different purposes to enhance their overall washing and drying performance:

1. Salt:

   • Water Softening: Dishwashers require salt primarily for water softening. In regions with hard water, characterised by a high concentration of minerals like calcium and magnesium, these minerals can accumulate in the dishwasher and on your dishes over time. Hard water can also diminish the efficacy of detergents.
   • Water Softener Unit: Dishwashers equipped with an integrated water softener unit have a compartment where you can add dishwasher salt. The salt plays a crucial role in regenerating the resin beads within the water softener. These resin beads attract and eliminate the hardness minerals from the water, thereby averting limescale build-up in the dishwasher and ensuring effective cleaning.

2. Rinse Aid:

   • Enhanced Drying: Rinse aid is employed to boost the drying performance of the dishwasher. It reduces the surface tension of water, facilitating its easy runoff from dishes and preventing the formation of water droplets on items such as dishes, glassware, and cutlery during the drying cycle.
   • Spot and Streak Prevention: Rinse aid serves to prevent spots and streaks on your dishes by promoting even water flow over their surfaces, thereby reducing the likelihood of minerals and detergent residues drying onto them.
   • Quicker Drying: By facilitating faster drying, rinse aid also diminishes the need for heated drying, which can be energy-intensive. This makes your dishwasher more energy-efficient.

To summarise, dishwasher salt is primarily utilised to preclude the accumulation of mineral deposits within the dishwasher and to uphold effective cleaning, particularly in areas characterised by hard water. Conversely, rinse aid is employed to elevate drying performance, avert spots and streaks on dishes, and enhance the general cleanliness of your dishware. Both salt and rinse aid contribute to the efficiency and effectiveness of your dishwasher, ensuring that your dishes emerge clean and free from unsightly spots.
