4.0 Wash technology

4.1 Basics

Four factors influence the cleaning results of washing in a dishwasher.

These can be presented in a pie chart known as the Cleaning Circle:

1. Mechanical action: Spray pressure of water.

2. Chemical action: Composition of detergent.

Detergent with greater cleaning properties can be used which,

in conjunction with the factors temperature and time,

compensates for the relatively low level of mechanical action in

a dishwasher compared with washing up by hand.

3. Temperature: Wash temperature.

During washing, temperatures from 68°F to 167°F may be

achieved, depending on the program selected.

4. Time: Duration of wash program.

During manual washing the contact time between the suds and

the item being washed is generally limited to less than 1 min. In

contrast, with machine washing, items in the load come into

contact with the suds throughout the pre- and main wash cycles

(10 min plus 30 min), a considerably longer time.

Throughout the cleaning process water is the linking medium between

detergent and load. It acts to dissolve and transport the detergent, and

remove the food residues. It also acts as a carrier for transferring

mechanical energy and heat energy to the load. To prevent calcareous

deposits developing in the appliance and on the load, the water is softened

before it enters the cabinet.
