Combination Products (2 In 1, 3 In 1) Function - Miele Dishwasher Care And Maintenance

Technical Information
2.4 Combination products (2 in 1, 3 in 1)
These products are a combination of detergent and rinse aid (2 in 1) or
detergent, rinse aid and salt substitute (3 in 1) and are dispensed during
the main wash step. The function of combination products is based on the
fact that they dissolve in stages and do not lose their effectiveness when
water is drained off. Their effectiveness is transferred from wash cycle to
rinse cycles. This is known as the carry-over effect. However, the
concentration is reduced from cycle to cycle.
Note
Previously there were combination products designed to dissolve
depending on certain pH values or temperature.
Note
There are also 4 in 1 products on the market. In addition to detergent,
rinse aid and salt substitute, they include a constituent for glass
protection. Some manufacturers include a glass protector as an
additive in the detergent but do not refer to this separately.
The glass protector is automatically released during the wash cycle so
no program modification is required. 4 in 1 tabs can be used in all
Miele dishwashers with and without 3 in 1 function, without any
adverse effects.
Properties
Under certain circumstances unsatisfactory cleaning or drying results can
be due to the use of combination products. Tests in application technology
laboratories have shown that the best cleaning or drying results are
achieved by using a standard proprietary dishwashing detergent in
conjunction with rinse aid dispensing and optimal water softening via a
dedicated water softener. Under laboratory conditions, all combination
products produce poorer results. Test institutes also recommend the use
of powder dishwashing detergent or normal (non-combination) tabs,
reactivation salt and rinse aid.
