8. Drainage • A pump motor drains the water from the drum.

decrease the water temperature gradually to prevent laundry from being
damaged and for safety reasons.
9. Untangling • It balances laundry load and senses the eccentricity of the load, to only
(Sensing allow spinning without vibration.
eccent- • If the eccentricity is worse than the allowed level, it repeats the
ricity) disentangling process. When the repeated time is more than allowed
