Some points to note when using the drying function
- According to a leading dishwasher expert, your dishwasher may struggle to dry your dishes, plates, and cups because they can retain water. This makes it difficult for dishes, plates, and cups to dry completely. Additionally, the material of the items also affects the drying level. Plastic is harder to dry than glass or ceramic due to its heat retention properties. Materials that retain heat better will support the drying process of the dishwasher more effectively.
- There are several ways you can help your dishwasher do a better job of drying. First, you can use a rinse aid to assist in the drying process. What it does is make water roll off your dishes instead of forming droplets on them. Second, if your dishwasher does not have a heating element, it usually has an option for you to manually turn on the drying mode.
- You should unload the items from the bottom rack of the dishwasher first. This way, any remaining water on the dishes in the upper rack will not spill onto the dishes below, wetting them.
- Leave space between dishes: you should not overload the dishwasher and should not let dishes touch each other. They will dry better if hot water or hot air can circulate between them. You don’t want to have to wipe them down again after they have been dried, right?
- Open the door slightly after drying: to allow warm air to escape, after 10 to 15 minutes, the dishes will be a bit drier. Some high-end dishwashers have an automatic door-opening feature. However, this type usually comes at a higher cost. You can do this manually after hearing the beep indicating that the drying process is complete.
- Utilize gravity: you can take advantage of gravity to help water flow off the dishes by placing items at an angle to avoid water pooling. This also reduces drying time, lowers electricity costs, and provides very good results. Just be a little mindful when placing dishes and items in the dishwasher. Just a few reminders and you will easily form a habit for this.
- You can use rinse aids or drying agents if needed.

1. What is the drying function of a dishwasher?

Drying technologies of dishwashers
Drying with hot air
- This is a technology that dries items by using hot air and occurs in a closed process within the dishwasher.
- At the end of the dishwashing cycle, the temperature of the washing water in the machine will be raised to a high level during the final rinsing phase, combined with rinse aid.
- As a result, it promotes the evaporation of any remaining water on the dishes, enhances the shine of pots, pans, and dishes, and maximizes bacteria elimination.
- Currently, high-end dishwashers all have enhanced drying features, meaning the drying temperature is higher, enhancing evaporation capability, reducing water adhesion on the surfaces of pots, pans, and dishes, completely eliminating bacteria just like your kitchen utensils have just been sterilized. You can use the dishes immediately after the washing program ends.

Zeolith Drying
The Zeolith drying technology helps dry dishes using energy beads based on a natural reaction. It does not require any other energy source or materials.
The operation process of this drying technology is as follows:
- The cleaned dishes proceed to the end of the washing cycle, which is the drying phase.
- At this point, steam will be sucked into a pipe and transferred to a compartment below containing Zeolith stones.
- Zeolith here will chemically react with the steam to produce a very high amount of heat. This temperature is enough to boil water.
- The hot air generated will then blow back into the main compartment, making the washed dishes hot and dry.
- The moisture on the dishes generated during the drying process is sucked back into the compartment containing Zeolith.
- This cycle is continuously circulated until the moisture is gradually sucked out and completely disappears.
- At that point, the dishes have been completely dried in the machine safely and cleanly.
This natural reaction of Zeolith stones has the ability to regenerate and continuously replenish. Because it only operates by absorbing water and releasing thermal energy. Therefore, there is no need to replace them throughout the machine’s lifespan. Thus, Zeolith drying technology is extremely safe, highly economical, and environmentally friendly. Zeolith drying technology is rated as very superior, saving electricity and increasing the durability of the machine. Dishwashers using Zeolith drying technology will have a higher price than those using hot air drying.
►►► In general, these two technologies both help to quickly and effectively dry dishes and pots, allowing users to consider their needs and finances to choose a machine with the appropriate technology.
Should you buy a dishwasher with a drying function?
Should you buy a dishwasher with a drying function? The answer is definitely: YES.
Because using a dishwasher with a drying function brings you the following benefits:
- Superior cleaning of dishes and utensils.
- Effectively eliminates pathogenic bacteria, ensuring health for the family.
- Saves time, effort, optimizes space, and investment costs.
- Instead of buying an additional specialized dryer, you only need to equip a dishwasher with a drying function and select the appropriate washing mode.
However, it must be emphasized: The main function of a dishwasher is to clean dishes, and in reality, there is no model that finishes washing dishes and opens to find them completely dry.
Why doesn’t the dishwasher dry the dishes?
There are several reasons why your dishwasher may not dry the dishes. In some cases, it is due to technical faults, but most issues are actually user errors. Below are some common causes and solutions to help you resolve the issue of water pooling in the dishwasher, not drying.
1. Incorrectly loading dishes, pots, pans…
Solution: Arrange cups and dishes so that the distance between them is reasonable. The bottom rack is the position for arranging larger dishes or bulky items like pots, pans, or large trays. The top rack is for arranging smaller items like cups, bowls, small plates, and smaller trays.
See details: How to properly load items into the dishwasher.
2. Removing items before the drying program is completely finished
The best practice is not to remove cups and dishes from the machine too early. After the machine finishes the washing program, open the door and wait about 15-20 minutes for the remaining steam in the dishwasher to escape. Then, remove the cups from the bottom rack first before moving to the top rack. Because if you remove them in reverse order, water from the top items will drip down onto the bottom items.
You can also choose dishwashers with an automatic door-opening feature after the washing cycle ends to make steam escape more convenient and easier. For regular dishwashers, the automatic door-opening feature is usually only integrated into the ECO saving wash program. However, nowadays, some high-end dishwashers have this feature integrated into most washing programs, which is very convenient for consumers.
3. Using too little rinse aid or not using it at all
Note that the amount of rinse aid must be sufficient for one washing program; you should not skimp on the rinse aid as it also affects the drying capability of the machine.
4. Choosing the wrong washing program
Choose a washing program suitable for the number of cups and dishes you need to wash and dry. Because if the washing program has a shorter duration, the drying temperature will also be lower. Therefore, choose a program with a longer duration and higher temperature for better drying of cups and dishes. ????
5. Dishes, cups… your items have a poor-quality coating or damaged surfaces
For items with poor-quality coatings, you should wash them by hand instead of choosing the dishwasher. Remember that plastic and Teflon are harder to dry. Plastic does not retain heat as well as other materials like glass or porcelain, and the surface tension of Teflon can cause water to bead up. This leads to cooking utensils made from these materials possibly remaining wet while other items are completely dry.
Water may not dry completely if the surfaces of the items show signs of damage. Water droplets may still remain in holes or chips even when the washing and drying cycle has ended. Avoid washing these items in the dishwasher.

6. Using a detergent with low drying effectiveness
You should switch to a different detergent that has a higher drying effectiveness ????
7. If the water is not hot, your dishes will not dry. The dishwasher will detect the issue and display an error code
You should call a technician for repair or take it to service centers for the quickest resolution.
8. Consider technical issues
If the problem persists, there may be a malfunction with the thermostat or heating element of the dishwasher. If you suspect this is the cause, please contact an authorized service dealer.
