3. Put very simply, a washing machine is a device consisting of a perforated drum that rotates inside a container. Water and a chemical product are added, and rotating the drum creates a mechanical action that causes the detergent solution to move in and out of the linen, thereby establishing the detergent action. Functions of a washing machine:

4. Priority issues in programming: On creating a program, the intensity of each of the 4 basic parameters is regulated. WASHING PROGRAM WASHING PROGRAM Time Temperature Mechanical action Chemical action Programming in each phase: level and type of water, spins, temperature, etc. Seeking the best conditions Type of fibre Type and quantity of soiling The dye used in the fabric In terms of:

5. Washing phases depending on degree of soiling: The type and number of phases is determined in response to the degree of contamination: Consult the summary for Chapter No. 6, which explains each stage of the washing cycle.

6. Washing phases ~ Water level The choice of water level (the amount of water inside the drum) directly affects the detergent action. Low levels in the washing phase mean a higher concentration of chemical product. Higher levels are recommended during rinsing to provide more water to dilute the detergents. Consult the summary for Chapter No. 6, which explains each stage of the washing cycle.

7. Washing phases ~ Type of water Table summarising where the use of each type of water is most suitable: Consult the summary for Chapter No. 6, which explains each stage of the washing cycle.

8. Washing phases ~ Type of detergent The results of the washing process depend largely on the choice of the right moment for using each type of detergent. Some detergents cancel each other out and others do not achieve their full potential. Consult the summary for Chapter No. 6, which explains each stage of the washing cycle.
