I've been trying to work out how long I've had this dishwasher. I assumed it must have been the third one in 22 1/2 years, but I've found a guarantee going back to the 90s and have worked out that it's only the second.
When we moved here, I bought a Hotpoint. It cost in the region of £250 and I paid for a 5 year guarantee. In that time, it had repairs which would have cost about £280. It lurched on for another year or two before it packed in completely (one time, it broke down, full, on Christmas Day) but it was certainly enough to put me off that brand for life.
That means that the current Bosch dishwasher has lasted me, with very little problem at all, for about 16 years. It's only in the last few days that I've had to rinse cups etc before putting them in, normally it is fine, though recently not quite as good as it was. I remember buying it on the recommendation of friends who had been bemused to see how little I could put in the old one without washing quality going way down. I use it pretty well every day, sometimes twice.
So this one owes me nothing at all, and I'd be perfectly happy to buy one again, but Blue Witch, who does her research SO THAT I DON'T HAVE TO (thanks ever so, BW, xxx) says that Bosch and Siemens are owned by the same company but the latter is now better made.
I have been looking, so far, at models at the price I'm willing to pay (the JL website is useful for that because it gives a lot of information) and there seems to be little if anything to choose between them for energy and water consumption, noise and the various features.
If you've come here doing your own research, don't rely on me, I know nothin' about nothin' (it works better in a Norfolk accent). Go to one of the websites that does this sort of thing properly. Except, that I've been looking myself and what they don't mention, because they're reviewing current models, is longevity and that matters quite a lot to me.
