Washing machine tub
Most washing machines have an inner and outer tub. The inner tub is called a wash basket in top load washers
and a drum in front load washers. The outer tub remains stationary and holds the wash basket or drum, catching
the wash water so it can be drained out. The wash basket or drum is the part of the washer that holds the clothes
and rotates to wash them. They can be plastic, porcelain or stainless steel.
Washer agitator or impeller

In top load models, wash action inside the tub is aided by an agitator or impeller. An agitator is a central post that
twists back and forth, rubbing against clothes to help break apart soils. An impeller is a cone or disc that rotates
to rub clothes against each other to help get them clean. In front load models, lifters or fins keep clothes tumbling
in the drum.

Washing machine motor
The washer motor usually sits at the bottom of the washer in top load models and the back in front load
models. The most common type of motors used in washers are direct drive or belt drive. The direct drive motor
is attached directly to the wash basket, while the belt drive motor sits independently and uses a belt to turn
the wash basket.
Washing machine drain pump
The water drain pump is in the bottom of the washer, usually towards the back in top load models and the front
in front load models. The drain pump controls the removal of water from the tub throughout the cycle, draining
the tub after the main wash, after the first rinse and during the final spin.
