What is the 3 in 1 function in a dishwasher?
Many modern dishwashers feature a 3-in-1 function, but not all buyers know what it is. It's actually a very useful feature, and that's what we'll be dedicating our post to today. We'll decipher the 3-in-1 symbol, explain how the 3-in-1 function works, and explain the various options it offers.
What is the essence of this function?
The special 3-in-1 function allows the dishwasher to recognize tablets and capsules containing detergent, rinse aid, and salt. The composition of these tablets is complex, so the dishwasher must run a special program that will gradually dissolve the tablet layers at different stages of the wash cycle.
What does this do? It significantly improves dishwashing quality by introducing specific layers of the 3-in-1 tablet into the program at the right time. According to some Western experts, using the 3-in-1 system improves dishwashing quality by 8-12%. How does this feature work?
- We open the dishwasher door.
- We load the tablet into a special compartment for detergents.
- We launch any washing program.
- A special sensor will detect the presence of a 3-in-1 tablet and adjust the program.
- We wait until the wash is finished and take out the clean dishes.
Although the 3-in-1 tablet contains salt, don't leave the dishwasher's salt reservoir empty. Refill it regularly.
If you instead3-in-1 dishwasher tablets If you put in the washing powder and poured in the rinse aid, the sensor would have detected that too. The program would have been adjusted to accommodate the powder.
What tablets can be used?
If you've purchased a dishwasher with a 3-in-1 function, you'll soon be thinking about purchasing the right detergent. So, let's take a look at which tablets are suitable.
- 2-in-1 tablets. These are rare on the market today. These tablets contain only compressed detergent and rinse aid.
- 3-in-1 tablets and 3-in-1 capsules. These products contain salt, rinse aid, and detergent. Tablets contain dry, pressed ingredients, while capsules contain them in liquid form.
- 4-in-1 tablets. These tablets contain four components: salt, rinse aid, detergent, and a special glassware protector.
- 5-in-1 tablet detergents. Multi-component tablets that, in addition to salt, powder, and rinse aid, contain solvents for difficult stains and protective chemicals.

Today, dishwasher owners are actively using 7-in-1, 10-in-1, and even 12-in-1 tablet detergents. All of these detergents are easily recognized by 3-in-1 dishwashers, so there's no need to worry.
If there is no such function?
Is this feature necessary in a modern dishwasher? I suppose it is, but what if it's not there and you still want to use tablets? Incidentally, many users ask this question: If the dishwasher doesn't have the 3-in-1 function, can you use tablets?
Most often, the instructions don't prohibit this; it won't harm the dishwasher, but it won't benefit you either. Imagine this: the dishwasher starts the wash cycle, dissolves the tablet in the first 20-30 minutes, prepares the cleaning solution, and successfully mixes the detergent, salt, and rinse aid into it. At the end of the cycle, you'll have clean dishes, washed without any rinse aid, since it dissolved at the very beginning.
It turns out that without the 3-in-1 function, there is no point in overpaying for multi-component tablets, since some of these components will be washed down the drain without benefit. There is no point in buying even 2-in-1 tablets, not to mention tablets containing 5, 7, 10 or more components.
In conclusion, I'd like to say that the lack of a 3-in-1 dishwasher feature doesn't necessarily harm the machine. If you use the correct dosage of detergent and rinse aid, you can achieve stunning cleaning results, even without fancy technical features. Good luck!
