just a word of warning, last year our dishwasher went up in flames, we had finished tea and cleared up put the machine on to do it's thang and went to watch TV, half hour later I heard some strange noises the OH thought it was the dogs, but I went to check anyway and knock me down with a feather the kitchen was full of really gagging horrible black smoke, luckily we had the lorry fire extinguisher in the house ( don't ask )
and we put the machine out, claimed on the insurance they had to send an engineer out to sign the death certificate, He reckons that they are one of the worse things for spontaneously catching fire and (some)insurance companies are not paying out if you leave them running unattended.
Since then we do not leave ours running unless we are there. Just thought I'd pass that on, oh we had an Hotpoint
