Water pump: This circulates the water through the machine, rotating in two directions. It’s used for circulating the
water through the wash cycle and also for draining the water during the spin cycle.
Water inlet control valve: This is located near the water inlet point, which is opens and closes automatically when
you load the clothes, depending on how much water is required.

Drum: Did you know that washing machines actually have two tubs? The one you see where the clothes are
loaded is the inner drum, which moves around the washing machine and is perforated with holes to allow the
water in and out. The outer tub contains the inner drum and the water, stopping it from leaking into the rest of the
machine and supports the inner drum.
Agitator or paddles. This is located inside the tub of the washing machine and helps perform the cleaning of the
clothes. Most fully-automatic washing machines have these paddles on the rotating inner drum which is controlled
by a rotating disc, whereas semi-automatic washing machinesuse an agitator that rotates within the machine to
produce a current in the machine. Either way, these are designed to move the clothes around during the wash
to allow the detergent to work and remove dirt particles and soiling from your clothes, helping the clothes rub
together while washing.
Washing machine motor. This is combined with the agitator or the disc that turns the drum, it produces a rotator
motion. This is basically the mechanism that gets your machine going.
Drain pipe. All the dirty water from your washing is expelled from the machine via the drain pipe.
Printed circuit board (PCB). This is where you’ll find mainly the electronics that operate the machine from elec-
trical components to circuits. These can be programmed and help operate the machine, acting as the artificial
intelligence for the washing machine, sometimes even deciding on the time needed for rinsing or washing.
Timer. This helps set the wash time for your clothes, which can be set manually or automatically.
Heating element. This heats the water up in the washing machine to the desired temperature.

Different types of washing machine :
There are four main washing machine types available. Each offers the user something different, so keep reading
to find out the pros and cons of each type, in order to choose the right one for you.
Top-loading washing machines:
Top-loading washing machines are generally considered more convenient than their front-loading counterparts,
particularly for those with mobility issues. There is no need to bend down while you load and unload laundry. In
addition to this, top-loading washers can have a larger capacity and can be fitted into a tighter space, as they
don’t require space for the door to swing open while you crouch. If you have a traditional London apartment, this
feature can be very useful.

Other top-loading washing machine characteristics include:
Can add clothes mid-cycle
Often a more budget-friendly option
Top loaders can be harsh on clothes
Front-loading washing machines:
Front-loading washing machines are more efficient than top-loaders, as they use less water and electricity. Often,
these laundry machines have a greater variety of cleaning options and features than their top-loading cousins.
More front-loading machine features include:
Less wear and tear on your clothes
Cleans laundry more efficiently
Accommodates more fabric types and stain levels

Often slightly more expensive than top-loaders
Integrated washing machines:
A ‘stow away unit’ is a fantastic option for anyone who is looking for a seamless, modern aesthetic. In general, this
would utilise a front-loading washing machine, with a few key differences. Most importantly, the washing machine
should fit into the cabinetry or walls of your home and will blend in with the features that surround it.
