Very few manufacturers have produced direct drive washing machines, as opposed to the normal conventional system used in the vast majority of machines available on the market.
There is always a lot of hype around a launch of something new in the washing machine world. It may well be worth taking you through the differences between the systems, and the pros and cons for both system. You may find this useful when selecting your new washing machine.
One point to make up front is that the direct drive system has been around for quite a long time, and most manufacturers have not taken it up.
The main difference is that the direct drive system does not work on the normal drive belt and pulley system, used in most washing machines on the market today.
On a direct drive machine, the system itself is bigger than the normal belt and pulley system. This means that the weight is carried at the back of the machine, and will restrict the size of the drum.
Pros and Cons of the Direct Drive System are set out below, but please be aware that most of the Pros are from the advertising claims for this system.
It is claimed this system uses less parts, which they suggest will mean less problems. Due to the additional sensors required, the difference is not necessarily less parts, but more like different parts.
The lack of the belt and pulley in the direct drive system means there is less wear and tear, and the machine will last longer – so it is claimed. However, over the last 20 – 30 years, the design and manufacture of domestic washing machines has improved considerably and it is now very unusual to come across problems with belts stretching. It is fair to say this was a common problem in the past but rare these days. In most cases when the belt does fail, it is generally down to the way the machine has been misused by its owner over a period of time, specifically by constant overloading. Not only does this cause problems with the actual washing of the clothes themselves, it can cause the drum to be off-balanced, putting strain on the belt and pulley system.
The motor itself is attached directly to the centre of the drum, making it more stable and thus reducing vibration. This is not necessarily the case. With most washing machines, excessive vibration is caused by poor installation, meaning that the machine is not level, causing it to rock from side to side during the washing cycles. Also, overloading can cause a machine to vibrate as it tries to move the drum fast enough to spin clothes, putting unnecessary strain on the belt.
There is no brush in the direct drive system, which reduces the amount of friction and the washing machine is, therefore, extremely quiet. This is true, but can also be said of induction washing machines that are available on the market. One thing to bear in mind if you are looking for a very quiet machine, an induction machine will be more expensive.
The claims are that a direct drive washing machine is more stable. Unless you are comparing the direct drive with a very cheap machine, the fact that vibration is caused with the high spin speed, you will probably not notice any improvement at all.
You can obviously choose to buy any kind of washing system for any appliance that you want, but there seems very little point in the direct drive system, especially if the cost is higher than the normal belt and pulley system.
