Like my mega efficient Bosch dish washer, that cant wash dishes unless they are clean to start with.


When my dishwasher seems to not wash properly, I usually find bits of rice in the jets.

I've got a Bosch dishwasher, about 3 yrs old, it washes much better than the old AEG. Even on the most energy and water efficient programme it normally gets oven casserole dishes clean as well, unless really baked on stuff (and the instructions tell you to not rinse dishes)

When mine doesn't wash properly I just ask her to do them again.

a mate has an older model and mine was as close as I could get to his. His roasting dish goes in straight from the oven and comes out clean. My machine struggles to clean the plates, but it does pass the A(or A++) rating it has.

Its broken. My really cheap A+ machine will clean anything, other than scrambled eggs, off almost anything. I have never found a dishwasher that can cope with egg properly.

It is the familiar trick known as "designing into the tolerances". Legitimate but misleading.

Simply, for example, if you are working to a requirement with a

10% tolerance, and you can actually reliably control to 2%, then depending on which way the advantage falls, you aim for either +8% or -8%.

First time I came across this was after the GEC takeovers, and the old AEI transformers factory at Wythenshawe was building transformers designed by GEC Rugby. I still remember the undisguised scorn when the AEI engineers saw the GEC technical data sheets and found that they had been doing exactly that.
