One thing that has changed in the 8 years since I last bought one, is that instead of 2 water inlets for hot and cold, there is now just one. Cold water only machines are apparently the norm now (here in the UK at least) for a number of reasons discussed in detail by service engineer and white goods expert Andy Trigg. Chief among them is that modern washers use much less water then in the past, and heating this small amount in the machine is usually more efficient than using water pre-heated by your boiler, which will have cooled in the pipes and therefore take time to run hot.
We tend to think of electronic devices as evolving to become increasingly complex as more features and "intelligence" are built in to each new generation. Here though is an admirable example of an element being deliberately taken away and sold to us as a "feature".
However, simplicity isn't about blindly removing things. Every decision, whether adding or removing something, needs to be weighed up carefully and justified.
While I'm instinctively attracted to the idea of machines with fewer parts and therefore fewer things to go wrong (and of course to the environmental benefits of using less energy), there are valid arguments in favour of keeping the more complicated dual-inlet design, as put forward by several participants in a lengthy discussion on Andy's blog.
As I rarely wash above 30° I'm more than happy to dispense with the (for me) unnecessary complexity of a second pipe/inlet, but the point is that decisions about how simple things should be are rarely simple.
However much we may value and strive for simplicity, it's important to accept that a degree of complexity may well be justified.Back to the top
