Front Load Washers…..The process described

The washing result depends on four main components after water has entered the wash bowl. The amount of water can be determined by the load or a fixed level pressure switch. 

  1. Mechanics
  2. Chemicals
  3. Heat
  4. Time

These all play a role. One part of the process cannot be changed without affecting the other three

The amount of detergent can be reduced and compensated with a longer washing time for example

The amount of detergent is relevant to the hardness of the water.

The washing mechanics, that is the way the laundry is dealt with in the washing drum, affects the washing result. The principle is that the speed of the drum turning must be such that the washing follows the drum up and is dropped as far a distance as possible. Too high a speed would mean that the laundry would follow the periphery of the washing drum and not drop down.

For most cycles best washing results, the washing drum should rotate at about 50 rpm. This gives the greatest drop height as a general discovery. On average, makers have designed their machines to rotate on wash at this speed and to rotate in each direction for about twelve seconds. The drum remains stationary in between direction changes for about three seconds. Different cycles my vary this slightly.

The drop height is very important to the end result; an increase in foam or water volume decreases the quality of the washing result.

The chemical component consists of detergent in water. In order for detergent to work properly it must be dosed correctly. The hardness of the water is relevant i.e. soft water requires less detergent. You will have to determine the hardness of your water to make choices about dosing. An insufficient amount of detergent can cause the washing to become dirty because the dirt is not broken down. Too much detergent can cause too much foam.

The temperature during the wash is the key to achieving the best results. In general it can be said that a higher washing temperature improves the washing effect, but as not all laundry can tolerate high temperatures, there must be a compromise. A common temperature used normally that suits most fabrics is fourty degrees. A sixty degree wash is suitable for towelling. And should be used at least weekly. Continuously washing at low temperature often leads to bacterial growth .The various components of the chemicals work at their best at different temperatures. Slow heating is an advantage. The detergent ingredients that work best at different respective temperatures are then given time to act effectively. A slower heating time improves the wash result.

Washing time affects the time of mechanical process and chemical process

This description is based on a standard regular cycle. It is meant to give you an overview of the principle of horizontal axis washing. Some cycles may be a little different; for instance, some cycles are shorter and accept more water to produce an adequate result.
