2: What do you think the monthly maintenance cost for a dishwasher is?

The costs for a dishwasher to operate include the following:

A: Electricity cost

You can rest assured about electricity consumption as dishwashers use less than 1 kWh for a washing cycle.

For example: If you are using the Kocher KDEU-8835 model, which has the lowest energy consumption for a washing cycle at 0.9 kWh (this model has an energy standard of European A+++). In a month, it consumes about 27 kWh. Assuming the electricity price is 2000 VND/kWh, you will spend about 54,000 VND on electricity per month.

B: Water cost

Using a dishwasher saves a lot of water compared to washing dishes by hand.

The Kocher dishwasher consumes less than 10L of water for a washing cycle. For a family of 4-5 people using the machine daily, 10L of water can easily wash 10 cups, 10 bowls, 20 plates, 20 sets of cutlery, 3 pots, and some other kitchen utensils. In contrast, washing by hand would require about 25-30L of water for one wash.

The estimated water consumption when using the Kocher 8835 dishwasher is about 9L per cycle. In a month, it will use about 270L of water, equivalent to 0.27 cubic meters (m3). With the water price at 6000 VND/m3, the monthly cost is less than 2000 VND.

=> The total cost of electricity and water/month when using the Kocher dishwasher is approximately: 56k/month.

C: Cost of detergent tablets, rinse aid, salt, and cleaning solutions

To ensure the dishwasher operates well, lasts long, and maintains its lifespan, specialized products for dishwashers are essential. You cannot use regular dish soap.

For detergent tablets:

Using detergent tablets means you have to cut them for each wash, and you can’t measure the exact amount accurately. The price for Somat detergent tablets is about 250k for 28 tablets. Thus, the cost of using detergent tablets for the dishwasher is about 134k/month.

For powder detergent:

You can easily adjust the amount of powder needed for a cycle. The amount depends on how many dishes your family uses. You should pour just enough to avoid excess that makes the dishes sticky. If you use Somat powder, the market price is about 160k for 1.2kg, while Finish powder costs 210k for 1.2kg, and you would only use 0.6kg in 6 months. Therefore, if you use Somat powder, the monthly cost is 13k, while Finish powder is about 17k.

For rinse aid:

Rinse aid helps increase shine and dry dishes faster. You can use it or not; if you want your dishes to be spotless, it’s recommended to use rinse aid. If you use Somat rinse aid, the price is about 70k for 500ml. You would only use 400ml in 6 months, so the cost is about 10k/month.

For salt:

Dishwasher salt is a very important specialized product for dishwashers. The salt contains components that can reduce water hardness and remove Ca+, Fe+, Mg+ ions from the water source, helping the machine last longer and operate more efficiently.

Currently, there are many types of dishwasher salt available for you to choose from, depending on your budget. If you choose Somat salt, the price is about 70k for 1.2kg, which lasts about 6 months. The cost is about 12k/month (however, the amount of salt used depends on the hardness of your household water).

The cost of accessories for the dishwasher to operate for one month is approximately ~ 35k/month (if using powder detergent; if using tablets or other specialized products, it may be more expensive).

The total cost for a Kocher KDEU-8835 dishwasher to operate for one month is approximately: (electricity and water cost + specialized products for dishwashers) ~ 56k + 35k = 91k/month

D: Other costs

In addition to fixed costs, users often worry about other incidental costs such as maintenance or repairs when malfunctions occur. This cost is very difficult to estimate in advance as it depends on the specific technical faults, and the replacement parts will vary in price. However, if you choose to invest in high-quality equipment from the start, the machine can operate stably for several years, even decades, without worrying about minor breakdowns. In the field of premium kitchen appliances, Köcher is proud to be a pioneer in Vietnam, bringing German technology into induction cookers, providing optimal solutions for durability and long-term safety for every family.

In conclusion, with a converted cost of less than 100k per month, you can reduce the burden of household chores, thus gaining more precious time for family, children, and enjoying moments of rest, relaxation, and self-care. This investment is entirely worth it to elevate your quality of life. Be a wise woman by proactively choosing smart, convenient products for yourself and your family today.
