The consumption in the Easy-care program changed from 65 l(0.45kw) to 58 and then 55 and to 49 l (0.44 kw).

Delicate program used to use 75l of water (0.4kw) and it got reduced to 65l (0.35/0.33kw).

Woolen program used to use 60l (0.2kw) of water before 1997, then 25l (0.15kw); since 2000 it uses 35l of water and 0.23/0.22kw energy pr wash.

100 years of Miele washing machine:From brawn to brain

100 years of Miele washing machine:From brawn to brain

This year the washing machine celebrates its 100th anniversary: Back in 1901, Carl Miele and Reinhard Zinkann built their first wooden-tub washer and, in doing so, took a decisive step in the history of domestic appliances. Put poetically, this development was eventually to liberate the housewife from the drudgery of the scrubbing board.A century ago, Monday's work was hard graft and toil. On the eve of the big day, dirty laundry was sorted and steeped in soda lye. At the crack of dawn next morning, wood and coal would have to be carried in and a fire kindled. With bended back, the work continued: Soaked laundry had to be wrung out, rubbed with soap and stains scrubbed. By the time this was complete the laundry could be thrown in the water in the tub, which by now had reached the boil. With a wooden paddle (and a fair portion of elbow grease) the laundry had to be jostled and kept in motion in the tub. Once washing in boiling water was over, the laundry items had to be rubbed individually on a washboard - with hands chapped from wringing garments in soapy water. And rinsing was no easier either, as the process had to be repeated time and time again to ensure the thorough removal of lather. This was followed by blueing, bleaching and rinsing once again, washing woollens in lather and cleaning the wash tub. After washing came wringing, ironing and the starching of collars and table cloths. And Monday's fallout was still noticeable on Friday.And then, all of a sudden, a wooden tub washer, nothing more than a glorified butter churn designed by two young entrepreneurs from Herzebrock one year previously, arrived on the scene to put paid to laundry-day blues. Both machines relied on a cross-shaped wooden paddle inside the tub: On the one it churned cream into butter, on the other it jostled laundry.Strong arms were still necessary, though, to keep the laundry in motion. By 1904, though, even that changed: The agitator was now belt-driven: A leather drive belt connected an external motor to the machine. By 1914, the washing machine was a self-contained unit with its own electric motor.In the Thirties, metal tub washers were to slowly usurp their wooden counterparts. But Miele's unbreakable wooden tubs continued to be built through to the Sixties before finally being displaced by sheet metal. The first metal casing was enamelled in 1938. Since those early days, the art of enamelling has been perfected and has come to stand for the quality of Miele appliances.During the Fifties, the washing machine conquered more and more homes. In the early days, laundry had to be transferred dripping wet from the washing machine into a spin dryer - an unpleasant and messy business. But that stopped in 1956 with the introduction of the fully automatic washing machine, able to wash and spin in one and the same drum.This was followed just a few years later by single-knob controls - still today the best approach to programme selection on the market. In the quest for even better technical solutions, 1978 marks an important milestone with the introduction of microcomputers and sensor electronics. Solid-state controls today are the brains of every washing machine (and all other major domestic appliances) at Miele. Microprocessors, sophisticated circuitry and application-specific software form the basis for such innovations as programmes for hand-washable woollens and silks. Electronic controls have also made great contributions towards reducing water and electricity consumption. Over the past 20 years, consumption of both power and water has been reduced by 70%.

Thanks to the Update function which allows new and modified programmes to be downloaded onto an existing machine, Miele washing machines are future-proof - increasing the likelihood that Miele washing machines will continue to satisfy customer requirements far beyond the centenary of the first wooden tub washer.

Continuously setting new standards

Gütersloh. - Laundry care has been a domestic chore since time immemorial. Perhaps this fact was in the back of the minds of Carl Miele and Reinhard Miele when they set about taking the elbow grease out of laundry care more than 100 years ago. Since then, numerous innovations have been inextricably linked to the history of the washing machine at Miele. The age of the fully automatic washing machine, though, only dawned as recently as 1958 and since then Miele has produced precisely 20 million units.

Miele's first foray into the world of laundry care came shortly after the company was founded. This first model, launched in 1900, bore great affinity to a butter churn. However, instead of churning cream into butter, the central agitator jostled laundry in soapy water. The agitator in the washing machine rotated in both directions and was equipped with a flyweight to perpetuate motion. The first models were manually powered, but in 1904, electric motors were introduced, initially in combination with a belt drive system. By 1914 the motor had been internalised into the product. Nevertheless, manual drive systems continued to be perfected as electricity was by no means available in all homes. Within just a few years, Miele's range of washing machine models had grown impressively, consisting of 50 variations on 20 basic models by 1913.

In the mid-Twenties, Miele washing machines experienced a quantum leap in their development when the first coal- and gas-fired drum washers for commercial use were built. In this case, an electrically driven drum replaced the prior art involving the vertical vat-and-agitator design. The drum washing machine had a larger load capacity, and water could be heated or even brought to the boil in the machine. Gone for ever were the days when hot water had to be bucketed into the tub!

1930 saw the advent of the first domestic models with an all-metal drum, opening up the way for electric heating. From 1938 onwards, the metal casing was enamelled. In the Fifties, washing machines first began to be installed in kitchens, with considerable impact on machine technology and design. The age of the fully automatic washing machine at Miele was finally heralded in by the 'Automatic 505'. From then on, there was no more need to transfer laundry to a separate appliance for spinning.

In 1962, Miele presented its first washing machine with single-knob controls. Once selected, the machine's electrical controls determined wash times, mechanical action, water levels, temperatures, rinse cycles and spin speeds. This innovation served to consolidate Miele's position as market leader. The age of solid-state controls began in earnest in the Seventies when microprocessors were first used in washing machines. This revolution was first presented to the public at Domotechnica in 1978. By this time, Miele was already cashing in on its technological lead with a specialist department devoted to electronic controls at its Gütersloh headquarters.

Since then, electronic controls have been the heart and soul of every Miele washing machine, contributing towards perfecting laundry care. Today's washing machines can now cope with all manner of fabrics – even expensive woollens and delicate silks. Electronic controls are also an empowering factor in optimising the use of detergent, water and electricity and, in doing so, make a huge contribution to the environment. The proverbial durability of Miele appliances is, in itself, a major contributing factor. And to ensure that washing machine controls always incorporate the latest programmes and parameters, more recent appliances feature Miele's electronic Update function.

To mark this special event, Miele has launched a range of campaign models under the title Gala Grande. Alongside the W 4000 series, models from the classic W 3000 range are also available together with matching special-edition tumble dryers from the T 9000 and T 8000 series. The washing machines in this range have a higher spin speed than entry-line models and therefore achieve improved dewatering. The matching tumble dryers are available as either condenser or vented dryers. The campaign is planned to run from April to December 2007.
