The document provides an overview of washing machines, including their history, components, processes, and tips. It discusses how washing machines have evolved from manual washing on rocks to modern machines with microchips and smartphone controls. The key components of a washing machine are described, such as the inner and outer tubs, plumbing, drive mechanism, and pump. The washing process involves filling, agitating, draining, rinsing, and spinning cycles. Tips are provided on pre-treating stains, choosing the right water temperature, and avoiding detergent residue. Common problems like not spinning or draining and solutions are also summarized.

13. Plumbing
 It fills the washing machine with the correct
temperature of water.
• It recirculates the wash water from the bottom of
the wash tub back to the top (during the wash
cycle).
• It pumps water out the drain (during the spin
cycle).

14. Drive mechanism
 To agitate the clothes, moving them back and forth inside the wash tub.
 To spin the entire wash tub, forcing the water out.

tips

24. Pre-treat obvious stains
• Act fast and rinse stains in cold water
before they have a chance to set.
• Check the fabric before removing any
stain. Do not rub stains as rubbing may
push the stain further into the fabric.
• Avoid hot water on an unknown stain -
hot water sets many stains.
• Avoid the use of any chlorine bleach
unless the garment tag says it may be
used.
Washing
tips

25. Washing
tipsChoose the right water temperature
• Cold (20°C) Ideal for fabrics that might shrink or fade in warm water and
recommended for typical wash-and-wear items. Cold Power liquid and powder
is specially formulated for cold water washing.
• Warm (35°C) Recommended for permanent press items including light
to medium colors.
• Hot (55°C) Provides maximum cleaning for items that can stand hot
water without losing color or shrinking.

26. Washing
tipsAvoiding detergent residue
• Detergent residue is often the result of
detergent not being properly dissolved before
the wash. In other cases, placing washing on
the surface of a full machine before adding
detergent can cause air pockets to form under
the washload.
Lumps of powdered detergent are
more difficult to dissolve.To prevent
lumpiness, store your powdered detergents in
a dry area to avoid moisture pick-up

27. Comm
on
proble
ms
 Most washing machine problems are some form or
conjunction of the following symptoms:
- The tub will not spin
- The machine will not drain
- The machine is abnormally noisy
- The machine is leaking
- The clothes smell bad after the washing

28. Solution
If your machine will
not start
If your clothes smell
bad
There are usually
different causes for
noisy machines:
The rattling
sound is simple a
coin or another
item that was in
your pockets
The pump is filthy
and it has to
pump harder to
drain the water
