Dishwasher

Which dishwasher should you buy that not only cleans effectively, but also safely disinfects, and fits well in a Vietnamese kitchen? The following article from the Köcher technical team will help you understand the operating principles, selection criteria, and suitable segments for this product line based on years of consulting and directly installing dishwashers in Vietnam. 1. Does a dishwasher clean better than hand washing? This is the most common question that Vietnamese families often ask before deciding to invest in a dishwasher. The answer from technical experts is yes, and not only does it clean better, but the dishwasher also provides significantly superior safety in terms of hygiene and disinfection. When we wash dishes by hand in the traditional way, the maximum water temperature that human skin can tolerate is only around 45 degrees Celsius. This temperature is completely insufficient to kill stubborn bacteria and mold that cling to the surface of dishes. The dishwasher helps eliminate bacteria on dishes after washing, something that hand washing cannot achieve[/caption> In contrast, the dishwasher operates by using hot water at high temperatures ranging from 60 to 70 degrees Celsius throughout the washing cycles. Combined with this is the extremely strong water spray pressure from multidirectional spray arms, ensuring that hot water and specialized detergents can reach and penetrate the entire surface of the dishes, including the insides of tall glasses or the bottoms of pots and pans coated with grease. Especially, the current high-end Köcher dishwashers are also equipped with UV disinfection technology after the washing cycle is completed. This technology ensures that your family’s dishes are not only spotless but also safely sterilized, eliminating up to 99.99% of harmful bacteria for the digestive system. The practical benefits that a dishwasher brings to daily life: Time-saving: Frees the homemaker from 30 – 40 minutes of manual dishwashing each day, giving you more time to relax with family. Water-saving compared to hand washing: Many people think dishwashers use a lot of water, but in reality, dishwashers use water in a highly efficient closed-loop cycle, consuming only about 9 – 12 liters of water per wash, while hand washing under a running tap can use up to 30 – 40 liters of water. Protects the health of your hands: Prevents hands from prolonged contact with cold water and strong detergents, reducing dryness, peeling, or calluses. Drying and safe storage: Dishes after washing will be completely dried and stored directly in the sterile dishwasher compartment, without worrying about mold or insect intrusion. 2. Classifying dishwashers according to 4 important criteria To choose a suitable dishwasher, you need to understand how to classify this product according to the criteria below: 2.1. By installation method The installation method of the dishwasher directly affects the harmony with your current kitchen cabinet interior, and is also related to the complexity of the water supply and drainage installation. Fully built-in dishwasher: The entire body of the dishwasher is placed inside the cabinet, while completely hiding the control panel behind the door. This design offers high synchronization with the kitchen cabinet system. Freestanding dishwasher: This type of dishwasher can be placed directly in any available space in your kitchen without the need to cut or modify the existing wooden cabinet. This is the perfect choice for families renting or wanting to buy a dishwasher for immediate use without altering the old kitchen cabinet. Semi-built-in dishwasher: This is a hybrid dishwasher that combines both of the above designs. The dishwasher body is fitted into the cabinet space but the front remains visible. Classification of dishwashers by installation design[/caption> 2.2. By capacity (measured in European place settings) Choosing the right capacity for the dishwasher will help you gather all the cooking dishes of the day into one wash, optimizing operating costs. Note: The capacity of dishwashers is calculated according to European standards, where 1 place setting is equivalent to the eating utensils of 1 person including a plate, bowl, glass, and cutlery. Under 10 place settings: Very compact design (often referred to as countertop or mini dishwashers). Suitable for singles, families of 1 – 2 members, or studio apartments with extremely limited kitchen space. 10 place settings (Köcher X10, X10 PRO): According to Köcher, a capacity of 10 place settings is equivalent to 1 – 2 meals for a family of 2 – 4 people. Suitable for small families wanting to save space while still having all the premium features. 12 – 14 place settings: Mid-range capacity, well-suited for daily dishwashing needs for families of 3 – 4 members. 15 – 17 place settings (Köcher X15, X16): Suitable for families of 4 – 6 people. This is an ideal choice for larger families or those who frequently host guests, organize parties at home, and have a habit of cooking with many large pots and pans. For an average Vietnamese family of 3 – 5 members, a capacity of 15 – 17 place settings is the optimal choice. One wash gathers all the dishes of a day, including soup pots and frying pans. 2.3. By drying technology This factor directly determines whether your dishes are truly completely dry and safe enough to be stored immediately after washing. Passive drying with steam: This drying method utilizes residual heat from the final hot water washing cycle to evaporate water clinging to the dishes, and the steam then condenses on the cooler stainless steel walls of the dishwasher and drains away. The downside is that dishes may not be completely dry, especially plastic items which often retain tiny water droplets after the program ends. Enhanced drying: Creates a continuous flow of hot air, ensuring dishes are completely dry even plastic items. This enhanced drying technology is equipped on models like X15S and X15B from Köcher. Drying combined with UV disinfection technology: Combines enhanced drying with UV lights shining directly into the compartment after washing, ensuring dishes are not only dry but also sterilized, stored safely for up to 7 days without mold. UV technology and Ozone disinfection help prevent bacterial growth and kill 99.9999% of bacteria 2.4. By integrated smart features In addition to the basic criteria, if you are interested in modern technology, consider the following factor: Conventional control dishwashers: Users will have to observe and assess the dirtiness of the dishes to choose the appropriate manual wash program integrated on the dishwasher’s control panel (such as quick wash, standard wash, heavy-duty wash for pots and pans…). AI Wash integrated dishwashers: This is currently one of the smartest dishwashers (notably the Köcher X15 Smart AI). The dishwasher is equipped with a turbidity sensor system that automatically identifies the amount of dishes and the grease on the utensils to optimally allocate water, water temperature, washing time, and spray pressure. Köcher’s AI Wash X15 integrated dishwasher 3. 6 Criteria to identify a quality dishwasher If you have no experience buying appliances, you can apply the following 6 golden criteria from Köcher to evaluate the product before purchasing: 3.1. Actual capacity and smart rack system design Many cheap dishwashers claim a capacity of 15 place settings but only have 2 racks and a fixed non-flexible grid design, making it difficult to arrange large pots and pans. Quality standard: Dishwashers with a large capacity of 15 – 17 place settings are designed with a system of 3 independent racks (the top rack for knives, spoons, and chopsticks; the middle rack for small dishes and glasses; the bottom rack for large plates, pots, and pans). Additionally, the dish racks are designed smartly, allowing for flexible folding or height adjustment of the middle rack to optimize space when arranging pots and pans. How to check: Pull out the entire rack system of the dishwasher and inspect it. The dishwasher compartment needs to be flexible, spacious, and suitable for the cooking habits of Vietnamese families 3.2. Pressure spray system and multidirectional spray arms The spray arm system of cheap dishwashers is often limited in spray angle and has weak water pressure, leading to dishes in hidden corners or the top rack not being completely cleaned, still having food residue after the cycle ends. Quality standard: Good quality dishwashers are equipped with at least 2 rotating spray arms (top and bottom) for 2-rack models, and ideally 3 independent spray arms for 3-rack dishwashers. How to check in-store: Observe inside the dishwasher compartment to count the number of spray arms in the racks. 3.3. Active drying technology and storage capability after washing Vietnamese people have a habit of cooking daily and want to store clean dishes immediately. Quality standard: Dishes after completing the entire washing cycle of the dishwasher need to be completely dry so that users can store them in the cabinet. To optimize further, the dishwasher compartment should meet sterile standards to safely store dishes for up to 7 consecutive days. How to check: Read the information on the product catalog or ask the consulting staff. Prioritize dishwashers with active drying technology and storage capability after washing 3.4. Extremely low noise control level during operation Dishwashers are household appliances that operate for a relatively long time for each washing cycle (usually lasting from 2 to 3 hours). Additionally, most Vietnamese families often have the habit of running the dishwasher at night after dinner so that clean dishes are ready for use the next morning. Quality standard: The noise level when the dishwasher operates at maximum power must be strictly controlled at below 50 dB (ideally fluctuating from 42 dB to 46 dB – equivalent to a whisper or a gentle breeze). How to check: Stand close to the dishwasher to feel the vibrations of the outer shell and listen to see if the sound of the motor is smooth and pleasant. 3.5. Standard installation size, perfectly compatible with Vietnamese kitchen cabinets Many families buy imported dishwashers from Europe but cannot install them into the existing lower kitchen cabinet because the machines are too tall (usually up to 85 cm). Therefore, you should note: Quality standard: For standard European built-in dishwashers, the overall width must meet 60 cm and the height should range from 81 – 82 cm (after removing the top cover of the machine). How to check: Measure accurately the 3 size dimensions: width, height, and depth of the cabinet space intended for installation at your home before purchasing a dishwasher. Installation size of the dishwasher 3.6. Integration of diverse smart washing programs compatible with Vietnamese kitchenware Vietnamese dining utensils are incredibly diverse in materials, from traditional glazed porcelain bowls, delicate crystal glasses to thick cast iron pots that are greasy and burnt. Therefore: Quality standard: The dishwasher should have at least 6 to 8 different specialized washing programs such as quick wash, eco wash, heavy/intensive wash at high temperatures of 70 degrees Celsius, and a program to protect delicate glassware. How to check: Carefully read the list of washing programs displayed directly on the dishwasher’s touch control panel or ask the consulting staff to explain in detail the function of each button displayed on the dishwasher’s LED screen. The dishwasher should have at least 6 to 8 different specialized washing programs 4. How much does a dishwasher cost? Suggested suitable costs Currently, in the Vietnamese market, genuine dishwasher products have very reasonable prices ranging from 12,000,000 VND for common dishwashers to 25,000,000 VND for the highest-end smart dishwashers imported directly from Malaysia. 5. FAQs – Frequently asked questions about dishwashers Can dishwashers wash large thick pots and pans? Absolutely can. However, the effectiveness of the arrangement will directly depend on the actual capacity of your dishwasher. Is it necessary to connect the dishwasher to the existing hot water pipe? No, it is not necessary. Köcher’s genuine dishwashers are equipped with a built-in intelligent heating element inside the machine compartment. You only need to connect the dishwasher to the regular cold water supply pipe of your home and plug it into the power source. Is the installation process of the dishwasher complicated? The process of installing a dishwasher is quite simple and only requires 3 basic technical connections: connecting the water supply pipe (using the common cold water supply pipe), connecting the drainage pipe (connecting to the sink drain pipe), and plugging in the power cord. How much electricity and water does each washing cycle of the dishwasher consume? The specific electricity consumption and water usage depend entirely on the rated power of each dishwasher model and the washing program that your family chooses for daily cooking. In general, Köcher dishwashers equipped with Inverter technology operate extremely efficiently, consuming only about 0.8 to 1.1 kWh and from 9 to 12 liters of water for a complete washing and drying cycle of dishes. 6.
